Addition 2004+ to the list of Asymmetric aircraft
    Nov. 18th 2004 - February 08th 2010, by X.Toff for Unicraft Models

  [My friend Igor must give of course a full priority to producing and sending Unicraft Models, creating new ones, so he needed help to update his great Asymmetric-planes main site with 2003 additions of mine. As I am not a professional, just an enthusiast ignoring how to handle Copyrights, I give here just reduced or simplified pictures, inviting the interested people to find the very source. As well, I have not required any payment, nor a free kit - I am willing to pay Unicraft kits at catalogue price, they deserve it.]

1/ Engine test beds
2/ Rotor-craft

4/ (What-if)
5/ (Toff-Tophe What-if)
6/ high-speed asymmetry
7/ asymmetric ailiners
8/ slight asymmetry

10/ asymmetric lifting-body
11/ simple asymmetry
12/ temporary asymmetry

1/ Engine test beds
1a- A Gulfstream II twin-jet having a single propfan on the port wing had been built by Lockheed for the NASA, to test this engine/propeller. On the starboard wing was just a balance boom at the tip. The first flight occured in 1987. (Sources: Jane's All the World Aircraft, 'Lockheed Aircraft' Pub.Putnam)
1b- Many aircraft have been used to test in flight one new engine on one side while keeping reliable power on the other side, providing some asymmetry. Still to test the UnDuctedFan in the 1980s, a propfan was on one side of the tail (with normal jet on the other side) on a Boeing 727, a McDonnell MD-80, a Yakovlev Yak-42; a long time before that, a Boeing 707 used 3 turbojets and the first turbofan, bigger and shorter; and more recently, a Boeing 747 used 3 normal turbofans and one with huge fan; etc... (Source: Internet, Air & Cosmos and Aviation International magazines)

2/ Rotor-craft
2a- A very famous asymmetric aircraft was not an airplane: the Lockheed XH-51A Compound. In order to increase very much the speed of helicopters, it was tried to add a single big turbojet laterally on a classical XH-51 (with the rotor, a classical additional dorsal jet was not possible). The first flight occured in 1964, and the World speed record for rotorcraft was established at 272mph =438km/h. The Kaman Seasprite Compound used, also in 1964 the same principle: a starboard jet. (Sources: Internet, 'Lockheed Aircrat' Pub.Putnam, Jane's All the World Aircraft)
2b- Of course, most of the rotorcraft are slightly asymmetric, using a single rotor rotating clockwise (or else: counter-clockwise) with an anti-torque system at the rear, on one side, pushing in a lateral direction for balance. But this is not the subject here, as well as the vertical asymmetry or front/aft asymmetry of almost all aircraft. Though, the old Hellesen-Kahn hélicoptère /double-plane illustrates with huge asymmetry the principle of usual rotorcraft... First (unsuccessful) flight in 1925. (Source: 'Le Trait d'Union' magazine, BFAB Pub.)
2c- A striking asymmetry was used on the Fairey Gyrodyne, replacing the rear anti-torque system by a lateral propeller providing both anti-torque balance and speed increase. The first flight occured in 1947, and the program was cancelled after the crash of the prototype in 1949. Less known, the SIAI-Marchetti SV-20C project would have used the Gyrodyne principle with a pusher propeller, on the basis of the SV-20A helicopter - all was cancelled in 1974. (Sources: Internet, 'L'histoire de l'hélicoptère' Pub.France-Empire, Jane's All the World Aircraft)

3/ Flying Toys
3a- After the rotating wing, there is the domain of circular flight. Many flying toys, with line-control, have only a port wing and a starboard weight for balance, as the NASS A, 1/2A, F2A. (Source: Internet)

4/ More What-if
4a- Jacques Lecarme's DaU was a fool's-day joke (April 1st 1968) featuring a port fuselage and starboard push-pull engines. It was mentionned that an inverted version was available for left-handed pilots, just a little more expensive... (Source: Aviation Magazine)
4b- The Ki-624 has been presented as a war-bird having a starboard fuselage and port push-pull propellers. With it was presented the couple General Motors XF2M-A&B, with either port push-pull or starboard-push/port-pull. And the Mitsubishi D5M used the same principle. (Source: Internet).
4c- From Japan also, the Hanger EP-6 would have used the layout of the DaU, simplified, without pretending to some historical background. (Source: Internet)
4d (12a)- Maybe from Switzerland, the Superdahu would have been a supersonic interceptor designed for circular Mach-2 cruise over a little country. Funny... (Source: Internet)

5/ Toff-Tophe What-if
5a- I have drawn many what-if twin-boom asymmetrical planes of the 1940s (fantasy). I present 4 of them here, selected among 32... (Source: 'The end of Forked Ghosts' book by X.Toff)
5b-  In 1992, I already imagined crazy twin-boom asymmetric shapes, I present here 4 of these puzzles-for-taxonomists: twin-boom or not? (Source: 'Catamarans du Ciel' book by X.Toff)
5c- At last, I have created a whole site for the fantasy/logical analysis of the asymmetric layout, I present 4 of them here, selected among 45... (Source: 'Asymmetric-or-Twin-boom?' on Internet by X.Toff)

Maybe someone else will create another page, after me. Anyway, thanks again to Igor for his marvellous site and collection!

-------------------------------------------------------------------- LATE ADDITIONS -----------------------------------------------------

(2005/01/11th) 2c'/: Thanks to Alex Panchenko, whose incredible collection of Soviet project models is fully presented and commented at http://www.ussr-airspace.com , it is possible to add another poorly known derivative of the Gyrodyne, belonging to the Myasishchev M-12 batch of V/STOL transports.
(2005/06/22nd) 2d/ Other way : the Dornier Conrado Patent DE 44 43 731 of 1996 includes a completely new reason to be asymmetric: for a VTOL with tilting wing/propeller, the simplest way is to have the power and free space at the center of the aircraft, thus a twin-fuselage layout (port+starboard), BUT if it is impossible to have such two half-fuselages (e.g. to hold one very big device), a single fuselage is still required and it may be lateral, asymmetric (Fig.5 of this Patent), leaving free the central axis. With contra-rotating propellers/rotors, it was obvious that this Dornier layout was not justified by helicopter torque, this is a completely new reason to be asymmetric, congratulations to the inventor! (Source: Internet)
(2005/06/24th) 2e (12b)/ the Papin-Rouilly Gyroptère (tested in 1915) and other mono-blade choppers could be seen as asymmetric, stopped on the ground or in a flight snapshot. Thanks JCC for this addition. (Source: Internet)
(2005/09/24th) 6a/ Thanks to Scott Lowther, preparing a great new book (see at
http://www.up-ship.com/Book/bomproj.htm), it is possible to add a very serious Northrop asymmetric flying wing project, that came after the B-49. Asymmetry allowed the crew to be put as far from the nuclear reactor as possible. (+2007/01/06th:) The same is presented as project 1956 at http://www.fantastic-plastic.com/NorthropNuclear-PoweredFlyingWingCataloguePage.htm.
(2005/10/14th) 7a/ In 1966, the Douglas designers considered 3-engined airliners coded D-967, either classically symmetric with a jet in the fin (like the Boeing 727: D-967-10, or the DC-10: D-967-1) or else with an asymmetric layout: the most asymmetric was the D-967-20 having wing engines with the single starboard one more external than the 2 port ones; less asymmetric was the D-967-30 with rear engines, close to the centreline. Such a layout was leaving the fin and rudder free from any fire or explosion in case a major engine problem occurred, with better controls/safety than a classical 3-jet. (Source "Great airliners", 6)
(2006/02/12th) 4e/ For aviation enthusiasts regarding aircraft with smiles and tenderness, the asymmetric layout main quality is originality, weirdness, not mechanics or aerodynamics, and this point of view is further illustrated by several Bv 141 cute caricatures (like the ones in the lovely Web sites http://modelbox.free.fr/dossiers/Eggs_P/ and http://www.desinaero.fr.st/). A Lego square Bv 141 may also have been built in a child bedroom… Aircraft are not only serious useful machines, they are pleasant silhouettes and dreams also.
(2006/04/28th) 8a/ The Vickers Viking and Valetta, of the late 1940s, are mentioned as slightly asymmetric because their port tailplane is truncated to compensate a slipstream asymmetry, probably due to both engines rotating in the same direction instead of counter-rotating for balance.
(2006/06/01st) 4f/ On the X-plane.org Web-forum , "Foxbat" presented several asymmetric-wing 3D weird models he had designed/virtually-built: OrigBBD, Asymaplane, TwistWing. They seem able to fly!
(2006/06/02nd) 5d/ On What-if modellers Web-forums , Tophe (myself) presented one hundred fantasy asymmetric planes, from 1939-45 symmetric sources or discussing about the twin-boom definition. This stands as an update to the "Forked Ghosts" books, unReal part.
(2006/06/03rd) 6b/ Thanks (again) to Scott Lowther, preparing his new book (see at
http://www.up-ship.com/Book/bomproj.htm), here are 2 of the 5 Boeing designs for the USAF supersonic B-59 program of the early 1950s. A true twin-boom asymmetric layout, like featured here, is very rare, out of the fantasy world.
(2006/06/28th) 9a (12c)/ Some air-launched aircraft have flip-out wings, extended for flight, and photographs show them flying with asymmetrical outspread, as the IMI-Brunswick ADM-141A Tald, whose 141-code reminds strangely the asymmetric leader: Bv 141.
(2006/06/28th) 2e' (12b')/ Apart of the very-old or ultra-light single-blade helicopters were some modern-looking VTOL airplanes, as the delta-winged Sikorsky S-57 (XV-2, and maybe XH-36) of 1954.
(2006/08/24th) 7b/ The VFW 624 airliner project has been presented in 1973, in 4 versions: 2 symmetric triplex-engine and what seem to be 2 asymmetric twin-engine.
(2006/08/27th) 4g/ A fake photograph from Erfawn Akhtar-Khavari brought another nice addition to the asymmetric airliners family: Boeing 777-3m. While many computer graphic Masters added engines on the M.A.P. funny site (8-engined Boeing 747 etc.) the first step is adding only one, and if it is not central, that builds an asymmetric plane… There is no mention of the asymmetric originality, so it was probably presented as a normal 2-engined 777 turned into a weird 4-engined 777, while the angle allows to imagine the external port engine is hidden (by the internal port one), but as this one has never been handled/"built", this "photographed" plane is a 3-engined incredible 777, and dreamers may appreciate even more!
(2006/08/30th) 5e/ I have myself reached the Modified Airliner Photographs group, to add twin-airliners and asymmetric airliners. I put this Boeing 757-3e. It was fun to make with Corel PhotoPaint, I thank also Adrian Pingstone and Wikipedia for the souce picture.
(2007/01/17th) 4h/ Asymmetric cargo planes were presented in the fantasy Howdah design project. A challenge for balance but convenient to upload/download...
(2007/01/31st) 4i/ A Web designer named Cutangus also imagined asymmetric planes of the late 1940s.
(2007/02/01st) 3b/ At the International Haud-Launch Glider Festival (IHLGF, 2003?) was presented an asymmetric-wing glider made by Bill Watson, flown successfuly with asymmetry in chord, span and dihedral.
(2007/03/04th) 5f/ I have created a Web site gathering almost 200 imaginary P-38 Lightnings, and 36 of them are strongly asymmetric...
(2007/04/13th) 10a/ A 1974 Boeing "Transport Concept" would have used the Burnelli lifting body principle, with a port cockpit and starboard jet.
(2007/10/28th) 5g/ I have created a Web site gathering my fake photos of aircraft, half of them being asymmetric jokes.
(2008/03/18th) 4j/ In January 1945, Roger Tennant explained in the magazine Flight that the best long range fighter would be an asymmetric twin-engine plane.
(2008/03/21st) 3c/ An asymmetrical control-line toy, reaching 150mph (240km/h), was already presented in 1949 in the magazine Flight.
(2008/03/22nd) 11a/ The Patent US 1,896,270 ("Airplane") filed in September 1929 by Theodore P. Wright (later engineer of the Curtiss-Wright Co.) presents a single-engine aircraft with good visibility, reduced fuselage vibration and reduced crash hazards. See Google patent or Flight magazine.
(2008/03/22nd) 5h/ I add here a (fake) Blohm und Voss Bv 141C with pilot and engine inverted: the goal would have been the ability to repair in flight the engine...
(2008/03/23rd) 5i/ I add also a (fake) Blohm und Voss Bv 141Z-2 with long range improvements in a Zwilling way: 2 fuselages and 1 half-pod for fuel, front observer as well as rear observer in a special pod, free from the pilot cockpit...
(2008/03/24th) 5j/ With gunners and lateral observers, the (fantasy) Blohm und Voss Bv 141Z-3 may have been rejected by very bad officials in 1944, it may be built anyway by very good modellers in 2014...
(2008/04/19th) 2f/ The Young Patent US3,820,743 of 1972 presented a Maple Seed Aerospace craft, VTOL with spinning flight... See Google Patent
(2008/04/19th) 4k/ A fool's day joke (April 1st 1980) was the Monoptère. (Source: Aviation Magazine)
(2008/04/19th+24th) 7c/ In 1971 was proposed an asymmetric 3-engined version of the Preliminary Boeing 747SP. Source: "Boeing 747" by Martin Bowman.
(2008/06/16th) 5k/ Coming back on the What-if modellers Web-forum, Tophe (myself) presented new fantasy asymmetric planes, from 1939-45 symmetric sources. This stands as another update to the "Forked Ghosts" books, unReal part (including the asymmetric Messerschmitt Me 610 and Me 710 together with the twin-fuselage Me 810 and twin-boom Me 910).
(2008/06/16th) 5l/ I have also created a Web site gathering my new fake photos of aircraft, half of them being asymmetric jokes.
(2008/10/03rd) 9b/ In the book " Illyustrirovannaya entsiklopediya samolyotov (OKB) V. M. Myasishcheva" by Bruk/Udalov/Smirnov/Arkhipov/Pogodin/Puntus, appeared a mysterious drawing of what seems to be an asymmetric variant of the Myasishchev M-63-2 Katamaran project – or this may be a mistake of the artist, not an external starboard foreplane nor a frontal starboard fin…
(2008/10/04th) 4l/ My friend Koen invented and justified a personal design for an asymmetric flying wing. See his Nest of dragons.
(2008/10/04th) 7d/ Jim Davis wrote that the preliminary Boeing 727 was designed as asymmetric, but refused by airlines as the public would not like that.
(2008/10/04th) 6c (12d)/ The Northrop-Grumman/DARPA Oblique Flying Wing (OFW) is a supersonic project, with a 2006 contract for a first flight 2010. See Flightglobal.
(2008/10/14th) 3d/ The Inter-Ex annual show (1984-2007) organised a classification for flying models, including an asymmetric group. There was a Blakert Bv 141B in 2001, and the drawing for the group is uncommon.
(2008/10/14th) 3e/ In 1997 the Academy of Model Aeronautics was selling an asymmetric version of a flying jet model, see Ironside.
(2008/10/18th) 6d/ Many more oblique wing projects (asymmetric airliners and fighters, twin-pod flying wings, etc.) are here and there, or on Desktop Aeronautics pages.
(2008/10/31st) 4m/ At least 2 asymmetric planes seem to appear in the computer game Crimson Skies: the Doppleganger besides and a twin-prop aircraft.
(2008/11/08th) 5m/ Differently asymmetric, the twin-engine flying-wing Blohm und Voss Bv 141N Nurflügel and the twin-tail Bv 141M have been designed (by myself) in 2008.





(2008/11/08th) 5n/ The (2008-"designed") Blohm und Voss Bv 141D could have been a reco aircraft with much improved lateral view.
(2008/11/09th) 3f (12e)/ The Pilotomago Web film seems to feature a radio-controlled plane flying with a half wing (the other half being lost in flight), before great fake effects to connect to a (safe, saved) piloted airplane.
(2008/11/24th) 12f/ Some composite aircraft hold lateral little airplanes, that may detach separately, the first that goes away leaving behind a (temporary) asymmetric composite. That started in the 1930s with the Zveno composites then went on in the 1950s with the Tom-Tom ones.




(2008/11/30th) 5o/ Zwilling the usual Bv-141N and the rare Bv-141И (2008, for left-handed crew) could have produced a sadly-symmetric double-pod twinboomer. But, if ever one engine fails, a dangerous asymmetry would result, so the port engine was moved backward and the booms were brought near each other, with a piece of external tailplane for balance, the result being still asymmetric (Bv-141NИ or Bv-141Nee).




(2008/12/06th) 1c/ In 1956, the Canadair CL-52/B-47B was a flying test-bed for the Iroquois jet, it featured an asymmetric engine pod underneath the starboard tailplane.
(2008/12/07th) 5p/ 1948 (or 2008?) designed Bv-141T Tourismus for 12 passengers enjoying the landscape.
(2009/02/23rd) 5q/ As the count of Bv-141 twin-boomers in the what-if-modellers group raised to 4, I added one of my own: the Bv 141Neu-Neu (meaning New-New in English, meaning Brainless-Stupid in French). Such a design would have a precise technical goal for the designer-hero: being fired away from the design bureau, to design no Nazi aircraft anymore...
(2009/03/01st-02nd) 4n (6d)/ The challenge to imagine a supersonic Bv-141 leaded to design an asymmetric version of the F-16A: F-141A. Tophe drew a first sketch, then nicely corrected and improved by ElectrikBlue, that featured it as 3D model using parts from Logic-Wizard's original F-16 model data.
(2009/04/11th + 2009/05/24th) 4o/ An old cartoon invented by by Chris Wren showed a reverted Bv-141, canard somehow (see The Aeroplane June 2009).
(2009/04/17th) 4p/ A 1/72 model at the IPMS Octoberfest 2007 seemed to have featured an asymmetric F4U Corsair (or F4U/P-51B hybrid, or Crimson Skies' Doppleganger turned plastic).
(2009/04/19th) 5r/ In my collection of plastic/resin models, more than a dozen of asymmetric aircraft inventions are featured.
(2009/04/20th) 4q (6e)/ After presenting his 8-engined what-if project RF-52 Condor, the great (amateurish) designer ElectrikBlue was invited by Tophe to turn it into a 4-engined asymmetric plane. This gave life to the Boeing RF-55B Condor, a kind of hypersonic Bv-141… Thanks EB/José!
(2009/05/03rd) 8b/ A McDonnell Douglas Patent of 1996 for Aerodynamic body having coplanar joined wings includes an asymmetric fuselage layout.
(2009/05/04th) 10b/ In 1976, Boeing Spanloader concepts were presented. Some of them, with 5 or 7 jet engines, were asymmetric, the nose and cockpit being lateral.
(2009/05/13th) 12g/ In 2007 was presented the RoboSwift bird observation VG airplane, turning by sweeping asymmetrically its wings.
(2009/05/13th) 5s/ The Gloster Meteor III.4 would have been an asymmetric version, joining a half Mk.III and a half Mk.4, to have asymmetry both in wing shape and jet size.
(2009/05/14th) 4r/ From Unicraft kits, the what-if modeller Flitzer invented in 2008 this asymmetric derivative of the Hs P.122 : Henschel Hs Schief.
(2009/05/17th) 5t/ The unmanned Bv-141RC is still asymmetric, even without lateral pod.
(2009/05/19th) 5u/ From ElectrikBlue's imaginative Mig-70 (with 2 turbojets + 1 ramjet) was created the MiG-77M with uncommon asymmetry of jet-nozzles and fins.
(2009/05/20th) 5v/ The twin-engined Bv-141zm zweimotorig has less asymmetry in weight, more asymmetry in thrust.
(2009/05/21st) 5w/ The F-104 Asy would feature simply dihedral asymmetry.
(2009/05/22nd) 9c/ The CWA Swan project has been presented with a radial engine only on the port wing. However the text (of The Aeroplane Spotter 9/7/1944) explained that the two 205hp in-line engines could be replaced by two 450hp radials, the sketch mixing both without such a construction being considered, it seems.
(2009/07/08th) 2g/ In 1965, the Lockheed CL-945 VTOL project featured a stowed rotor – becoming almost a classical airplane in cruise flight, while keeping a helicopter anti-torque device, uselessly asymmetric then…
(2009/07/08th) 5x/ A twin-boom flying disc was featured on a "Man's life" cover, presented in a Web forum and Weaver suggested that Tophe turned it asymmetric. So the port engine was discarded with Photopaint-6.
(2009/07/29th) 12h/ A Junkers Ju 88 was partly broken in flight, in 1941, and kept on flying 160km (100 miles), asymmetrically, without starboard taiplane. (See "Le Fana de l'Aviation" #477, Editions Larivière).
(2009/08/12th) 8c/ The Henschel Hs 298, in 1945, would have been an air-to-air missile (rocket-powered), with a little asymmetry. (See "Die detschen Flugzeuge 1933-1945", Lehmanns Verlag, 1964).
(2009/08/13th) 9d/ When only a profile is available, several layout hypothesis may be considered. In the book "Ceskoslovenska letadla" (Nase Vojsko, 1968) is a Czech text, that was uneasy to read, so the LE P-3.4 (project of 1949) might have been asymmetrical or twin-fuselage. At last, with Internet free translators, the twin-fuselage hypothesis appeared being the true one for this fighter-trainer, the asymmetry having just been a reader's dream...
(2009/08/18th) 10c/ The Roberts Wing body aircraft (Patent US3191883 of 1964-65) featured two fins, asymmetrical both in position and direction.
(2009/08/19th) 11b/ The Raymer Asymmetric GA Twin was an interesting design (dated 1981?) but has never been built it seems.
(2009/08/23rd) 12i/ The Supermarine 327 Spito prototype of 1937, not finished, was completely asymmetric, but unable to fly (and even to stand on the runway)...
(2009/08/24th) 4s/ The Science-Fiction B-wing Starfighter would have been a winged asymmetric space-craft, probably able to fly as airplane in some atmosphere.
(2009/08/25th) 7e/ The Roskam Asymmetric Trijet was an RC model of airliner.
(2009/08/26th) 5y/ The Blohm und Voss Bv-141E Ei (Egg) featured lengths reduced by 50% (as basis for an egg-plane model kit).
(2009/08/27th) 6f/ The McDonnell Douglas F-15 Staggerwing in 1977 improved transsonic drag with wing asymmetry (Patent US4,139,172).
(2009/09/05th) 8d/ The helicopter Boeing-Vertol 235 AAH, built as mock-up in 1973 had asymmetric cockpits and windscreens.
(2009/09/19th) 4t/ In 2008, an asymmetric Arado Ar-240 A-02 Asy was built by Jérôme Engel at scale 1/72.
(2009/09/20th) 3f/ The Paper Airplane Design Studio presented several Japanese asymmetric models in 2006.
(2009/09/20th) 3g/ In 2009, the Ninomiya machine with staggered planes was another Japanese paper plane.
(2009/09/20th) 3h/ An asymmetrical wing wooden plane was also built in Japan.
(2009/09/21st) 12j/ In 2009, a Rockwell Collins Damage Tolerance scale model of F-18 had part of its starboard wing removed in flight, while keeping control thanks to special electronics.
(2009/09/24th) 12k/ In 1996, the F-16HSR High Speed Research of the NASA featured temporarily a half wing with an experimental glove changing its shape.
(2009/09/24th) 3i/ Chinese paper planes featured staggered wings or starboard-only fin.
(2009/09/24th) 11c/ In June 2009 flew the XFC pusher unmanned aircraft of The US Naval Research Laboratory, with oblique wings and opposite winglets.
 
 
(2009/09/26th) 9e/ Sometimes, in an article, two half planes are compared, close to one another. Visually, this creates a kind of asymmetric airplane - like this (these) Dassault project(s) of mid-September 1956 in "Le Trait d'Union" #179.
(2009/09/27th) 9f/ Sometimes, the asymmetric aircraft that we guess is a temporary visual illusion, due to the angle of sight, making a 3-fuselage single-tail plane look like having only 2 lateral fuselages: one with tail and one without - then the plane would move and we would see there was just some alignment of the tail-carrying central-fuselage with one of the lateral fuselages.
(2009/10/07th) 5z/ Rarely, a profile of twin-engine airplane is presented with one lateral engine removed to show the short nose that it would hide. So there is the nose in front then a lateral engine, which looks like an asymmetric single-engine plane. It is possible from there to invent the other views. The single-engined Bristol Beaufighter came this way from pleasant profiles in the book "Interceptor fighters for the Royal Air Force" by M.Bowyer.
(2009/10/08th) 5za/ After the Blohm und Voss Bv-241B project (would have) created a symmetric Zwilling derivative of the Bv-141, the Bv-341B restored asymmetry, in a triplex pod layout.
(2009/10/11th) 5zb/ Of course the Blohm und Voss Bv-241B and Bv-341B have been themselves Zwillinged into the asymmetric Bv-241Z and Bv-341Z.
(2009/10/12th) 4u/ In 2009, the what-if designer Electrik Blue invented a MiG-29Z Zwilling, with a secret device in the front part of the starboard fuselage. The what-if modeller Tophe prevented interference with the starboard foreplane discarding this one (and the port tailplane for balance), into an asymmetric MiG-29Z-2.
(2009/10/13th) 9g/ Sometimes, another visual illusion may come from twin-boomers with separate tails and the central pod hides one of the booms, making the observer wonder: twin-boom symmetric or single-boom asymmetric? See the Pellarini Airjeep.
(2009/10/17th) 5zc/ Between the Bv-441 (Bv-241Z) and Bv-641 (Bv-341Z) was the Blohm und Voss Bv-541. This 5-engined reco aircraft was designed to carry a lot of fuel, for transatlantic flight back and forth without refueling.
(2009/10/18th) 5zd/ The Blohm und Voss Bv-741 (would have) avoided the need of rear protection by an increased speed: doubled power with no more drag.
(2009/10/18th) 5ze/ With the threat of jet fighters, 1944, were (or would have been) designed the 4-engined Bv-841 and 6-engined Bv-941, reaching (theoretically) 800km/h = 500mph.
(2009/11/03rd) 4v/ From the famous 2-engined RF-101 Voodoo, José ElectrikBlue invented the 4-engined RF-202 Zwilloo (Zwilling-Voodoo) and suggested that Tophe remove one fuselage. That created the 3-engined asymmetric RF-202R, half Northropish flying wing...
(2009/11/08th) 5zf/ Before designing the P.178 asymmetric jet, the Blohm und Voss team of course considered a Bv-141TL (jet derivative of the Bv-141).
(2009/12/08th) 6g/ In 2008, a thesis by R.W. Plumley at the Virginia Polytechnic Institute included a CGI drawing of Staggered Multi-Body aircraft, looking supersonic.
(2009/12/16th) 4v/ In 2006, the what-if modeller Rafael revealed the Yakovlev Yak-480, an airplane "built in 2013" from an old Messerschmitt Bf-109 and 2 turboprops... with high success!
(2009/12/16th) 4w/ In "1943" (according to the fantasy artist Stan Mott), maybe in 1957 in our world, Igor Sokerov's Chrysler Aeroflot carplane featured a port rear door and a starboard tail, it seems.
(2009/12/19th) 4x/ The what-if designer ElectrikBlue has created the Dassault Farfadet, a 66% scale Rafale (except cockpit and canopy: of course 100%), then the group Rafale+Farfadet gave birth to the Rafafale twin-plane, asymmetric.
(2009/12/20th) 4y/ The what-if designers ElectrikBlue and Stargazer2006 had fun creating the little Mirage 1000 from the big Mirage 4000, then Stargazer invented the Mirage 1000A with a F-16-like jet intake, requiring Tophe to build an asymmetric derivative of it. So, the asymmetric double Mirage 1001 featured both kinds of jet intakes, each one having good points and bad points.
(2009/12/23rd) 4z/ The what-if modeller Glenn dreaming of a Britten-Norman Twin-Islander, Tophe imagined several asymmetric versions of this Twislander.
(2010/01/17th) 5zg/ In X.Toff's book "Virtual Mustangs", many profiles have been mentioned as corresponding to either symmetric aircraft or asymmetric ones. This possibility has been illustrated with the P-51/3m or P-51/2m (with anti-torque little extra engine) on the update pages (what-if modellers forum).
(2010/01/18th) 11d/ The Cirrus The-Jet (future Vision SF50) single-jet design was considered in many ways: « even one with an engine mounted on the side, but un-surprisingly, it looked too un-conventional and who wants an asymmetric airplane anyway ? »…
(2010/01/30th) 5zh/ From the Mirage 1000 nice fake, and the source Mirage 4000, was created the Mirage 4001 asymmetric big & small...
(2010/01/31st) 4za/ The what-if designer ElectrikBlue created a 4-jet engined F7F Tigercat Jumojet, then 3-engined variants, including an asymmetric one.
(2010/02/07th) 5zi/ The what-if designer Wyrmshadow created a 3-engined Warhound mixing the Blohm und Voss P.170 layout (3-engined, double-fin, twin-lateral-booms) with Curtiss P-40 Warhawk parts. From this Tophe made a Warhound 2, 2-engined single-fin single-lateral-boom asymmetric derivative.
(2010/02/08th) 5zj/ When Unicraft Models presented the profile of a "Me 110" (future kit) looking like a Bf 109 with lateral engine, most visitors concluded this was a 3-engined plane, while Tophe imagined there was a single main engine, and a single extra little engine acting as anti-torque, asymmetrically. This turned wrong but was funny.
