About a few ridiculously big aircraft that didn't do much flying. Part 1

There are a lot of large aircraft flying. For instance let's look at the example, Antonov An-124.One of the larger planes ever. How many of them were built? 55. You might consider this a big number, however for example: Cessna 172- around 43 000 examples, over eight thousand B737, Flying Fortress- over 12 thousand. Ok, let's go back to big planes. 1502 Boeing 747s were built. Right, another large plane, the Airbus A340 (my favourite Airbus). Throught 20 years 377 were built.
Not all monstrous, gigantic and scarily big were so lucky. Some are old, some are relatively young projects. However they were all unsuccessful.
The list is in no order, it follows no rules of logic. Aircraft are limited to 5 being built.
Please write in the comments, about what would you like me to do a post about. I have a leak (not really) in my brain, therefore I'm losing inspiration. Just a little bit, don't worry.
I'll try to do part 2, but I'm a little bit busy/lazy/lacking inspiration. Write down some aircraft that I can write about in Part 2.
No.1. Nakajima G10N (0 built)

Nakajima G10N Fugaku. - En 1943 Nakajima por cuenta propia, inicio los estudios de un avión que fuera capaz de atacar territorio norteamericano en el otro lado del Pacifico, fue denominado Proyecto Z, como era de esperar, se reflejaría en el B-29 para iniciar el proyecto dado que este tenia el alcance y el resultado necesarios para llegara a territorio Japonés. El proyecto Z llamó la atención de los militares y la concepción dados ya reunidos por Nakajima sirvió de base para una petición común por parte de la Marina y el Ejército Japonés. Inicialmente Nakajima previo equipar el avión con motores de gran poder como el motor radial Nakajima Ha-505 de 36 cilindros (5.000 hp cada uno), tres en cada ala; sin embargo se vio que tales motores no estarían disponibles, así que se utilizaría los motores radiales Nakajima NK11A, cada uno desarrollando 2.500 hp. Definido esto, el ahora designado G10N1 Fugaku comenzó a surgir en la tablilla de los ingenieros. Basándose en un B-29, el G10N1 seria capaz de tomar un cargamento de 5.000 kg de bombas hasta los Estados Unidos y a continuación aterrizaría en Alemania. Para misiones más cercanas, el cargamento de bombas podría llevar hasta 20.000 kg, ellos como se mostraba las estimaciones, el G10N1 seria un avión muy impresionante, con cuestiones muy similares o incluso sobrepasando al mismo B-29. Sin embargo la cuestión fue si los japoneses estarían dispuestos a destinar los insuficientes recursos de guerra para la construcción de tan enorme avión, a la cual no eran completamente exactos de su utilidad para la situación de entonces. A diferencia de otros proyectos de grandes bombarderos en los cuales los Japoneses como el Kawasaki Ki-91 y el Nakajima G8N Renzan (que ya casi estaban en la línea de vuelo), el G10N1 permaneció solamente en el periodo de proyecto avanzado cuando la guerra llego a su fin. El G10N1 Fugaku no fue codificado por los Aliados, el proyecto Z fue cancelado en julio de 1944 y el Fugaku jamás fue construido. <BR> <BR>Dibujo del Nakajima G10N1 Fugaku: <BR><A HREF="" TARGET=_top></A> <BR> <BR>Características: <BR>Nakajima G10N1 Fugaku. <BR> <BR>Tipo: bombardero pesado de largo alcance, de seis a diez tripulantes. <BR>Planta motriz: seis motores radiales Nakajima Ha-54 enfriados por aire de 5.000 hp cada uno. <BR>Prestaciones: velocidad máxima 780 km/h; techo de servicio 15.000 m; alcance máximo 19.400 km. <BR>Pesos: vacío 42.000 kg; máximo en despegue 122.000 kg. <BR>Dimensiones: envergadura 63,0 m; longitud 46 m; altura 8,8 m; superficie alar 330 m2. <BR>Armamento: cuatro cañones Tipo 99 de 20 mm ubicadas en torretas dorsal, ventral y cola, mas una carga máxima de 22.000 kg en bombas. <BR> <BR> <BR>Saludos a todos y gracias por los post. - Fotolog

Japan faced problems with one type of aircraft during WWII. They never built an efficient strategic bomber. There were a few companies making aircraft, but the main one that wanted to finish the task of building a strategic bomber was Nakajima. In 1941 they first flew a plane called G5N, based on the DC-4. The specifications were quite decent, however the range was insufficient. Another, better, but smaller (sized) project was G8N. Again, the range didn't meet the expectations. 
Nakajima didn't give up. They began work on a project called Project-Z. The plans were quite decent, but none sufficient engines were found, changing the design a little bit. It still was stunningly big for an WWII airplane. The G10N Fugaku (mount Fuji, sounds scary) was approved by the Japanese military. The project was enormous. It's capabilities were quite impressive for it's times. Even now they are very good.

In the autumn of 1943, works on production facilities began. The project wasn't however considered so important, many top Japanese engineers didn't work on it at all, or where moved to different projects. The US army was closing Japan, different aircraft were more important and project abandoned. The documentation of the plane was obviously destroyed.
No.2 Convair  XC-99 (1 built)
Oversized B-36

Based on the B-36, it was the biggest piston engine powered airplane, only smaller than the Hughes Hercules. Designed by engineers led by Roberts R. Hoover began work in California. The hangar they used was to small. That just means, that this plane is awesomely big. Yes, indeed. The design with six engines turned back, the design was meant to produce more "pushing" power.Check out the specifications:
General characteristics
The plane was used in an impressive mission called "operation Elephant", transporting over 40 thousand tonnes of cargo (engines and other stuff used in building B-36 Peacemakers). XC-99 flew 19000 kilometres from Rhein AB to California, stopping twice. The XC-99 attracted everyone everywhere it went.
The USAF itself said they don't need such a big plane. One was only built as you have noticed. The XC-99 was retired in 1957 and is now preserved in Ohio.
No.3 McDonnell Douglas MD-12 (0 built)

Three viewsSame author and page as above.
The MD Donnell Douglas designers have shown a new design in 1991, it was basically a larger and modified MD-11. They called it MD-12X. The aircraft was meant to carry about 400 passengers. The MD-12 would be built out of composite material. The engines were placed like in the MD-11, MD Donnell Douglas designers didn't go so creative. Soon they changed it into a classic, A380 or 747 design. They also thought of the baggage hold to be in a way prepared for carrying passengers. In addition the cabin would have an area called the Panorama Deck, where 54 passengers could enjoy a view down. The tickets would have probably been very expensive, around 1000 Euros for a flight from Paris or London to New York, I guess. In the end a view of the Atlantic Ocean is probably very boring.The production was meant to start in 1994 and plane to fly in 1995. Eventually MD Douglas didn't have enough money and plans were deleted. Bye Bye oversized MD-12.

No.4 Conroy Virtus (0 bulit)
Double B-52 Mutant
This Enormous Freak Of A Plane Was Designed To Carry A Space Shuttle
NASA picture

Frankly speaking, this is enormous and very unreal. Mutant double B-52 SCA twin tail aircraft. It was designed to carry a space shuttle between it's large wings. The design was meant to carry the space shuttle between the B-52 based fuselage. Where would the pilots sit?!
At first due to design changes in the Space Shuttle programme, NASA wanted a plane that can fly from Kennedy Space Center to an altitude, where the shuttle can continue it's journey to space.One of the earliest designs was the Conroy Virtus by John M. Conroy, the same man that deigned the Pregnant, Mini Guppy and Super Guppy. Guppily (has that word ever even been used!) crazy idea!
The design was basically a JT9D (747 engines) powered twin B-52 fuselage aircraft with a wingspan of around 140 metres. In addition, the Virtus could carry the shuttles rocket boosters and external tank.
A 1/34 scale model was tested in wind tunnels, with positive results. The problem was money. What a surprise! (sarcastic).The size let the plane down, and in addition, Conroy Virtus required bulding new, bigger hangars for the plane. Lockheed later proposed a crazy double C-5 design (with six engines), but NASA decided that they want a normal aircraft. Therefore there would be no double DC-10, 707, DC-8 nor nothing different. In the end, NASA chose the 747-100, not the most usual, but more normal than the Virtus.
No.5 Sukhoi KR-860 (0 built)
Do you want to fold the wings?!

Courtsey of Wikipedia
To explain my choice, read through the technical data. Most importantly size, wingspan, capacity.
General characteristics
  • Capacity: 860-1000 passengers
  • Length: 80 m (262 ft 6 in)
  • Wingspan: 88 m (288 ft 9 in) with the wings unfolded or 64 m (210 ft) span with wings folded
  • Wing area: 700 m2 (7,500 sq ft)
  • Max takeoff weight: 650,000 kg (1,433,005 lb)
  • Powerplant: 4 × General Electric CF6-80E1A4B turbofan, 320 kN (72,000 lbf) thrust each or
  • Powerplant: 4 × Pratt & Whitney PW4168A turbofan, 305 kN (69,000 lbf) thrust each
  • Cruising speed: 1,000 km/h (621 mph; 540 kn)
  • Range: 15,000 km (9,321 mi; 8,099 nmi)
The aircraft was designed by Sukhoi, a company creating mainly fighter aircraft. The company expected the plane to first KR-860 to be built by 2000. The programme would cost around 10Billion $. Not bad! The aircraft could fold the wings like the new 777X design. In addition the outboard engine would be folded.
A 1/24 scale (better than the Virtus, ;P) at the 1999 Paris Air Show, 10 years after the Antonov 225 astonished everyone with it's size. Mainly the US. The project didn't succeed, due to lack of potential customers (I do agree with it, it would be worse than the Il-96 IMHO) and money. Both combined and everything is dead.
No.6 Tupolev Tu-244
A failed remake of the Tu-144
Tupolew Tu-244 Mockup vul.jpg
The work on this SST began in 1979, when Tupolev design bureau wasn't satisfied with the Tu-144.This project was based on the Tu-144, but also the Tu-160; for example, the same engines. One of the new features were FBW system logics used to control the plane, video cameras to help crews and new fuel-cryogenic fuel, that requires keeping in low temperatures. Not a problem. Tupolev intended to build around a 100 Tu-244 aircraft. One minus in my opinion, the plane needed three crewman. In the end (1993, not an end of anything) Tupolev abandoned the project due to it's cost. All in all the Tu-144 is the only SST ever built by Tupolev. And the Tu-244 was only a plan.
