Amazing unused aircraft designs

Throughout the years aviation has evolved dramatically due to no lack of trial, error and innovation. Here are some widely unknown designs of aircrafts that have been developed but either never came to be, can’t be built yet or do not have any particular use in society.

 NASA AD-1

Built in 1979, the NASA AD-1 proved that the wings of an aircraft could pivot quite dramatically without losing any of the planes’ stability.

 

Stipa-Caproni

The Stipa-Caproni was built in the 1930’s, with the propeller contained entirely within the fuselage. Although never put onto the production line, the aircraft worked and lead to the development of the jet engine.

 

Nemuth Parasol

The Nemuth Parasol was built by students of Miami University to prove that even a circular wing could keep an aircraft in flight.

 

Vought V-173

The Vought V-173 was an experimental place developed by the US. It was able to fly exceptionally slowly.

 

281 Proteus

Blohm & Voss 141

The Blohm & Voss BV 141 was a German tactical aeroplane, notable for its asymmetry.

 

Grumann X-29

Sikorsky X-Wing

The Sikorsky X-Wing aimed to combine the vertical lift of a helicopter with the forward speed of a jet plane. The project was dropped in 1988.

 

Lockheed-Martin P-791

The Lockheed-Martin P-791 was designed to combine buoyancy with aerodynamic propulsion, allowing it to shift heavy cargo loads quickly.

 

Beriev Be-200

The Russian Beriev Be-200 was a short-lived amphibious aircraft on a huge scale.

 

The White Knight Two

The White Knight Two is designed to carry spacecraft between the two fuselages and ferry them to the very edge of the Earth’s atmosphere.

 

McDonnell XF-85 Goblin

The McDonnell XF-85 Goblin was a ‘parasite fighter’ that was meant to be deployed from the bomb bay of a larger plane.

 

Bartini Beriev VVA-14

18ca58ofgljnajpgThe hulking Bartini Beriev VVA-14 was a soviet plane that employed vertical take-off.

 

Avro Canada VS-9 Avrocar

The Avro Canada VZ-9 Avrocar was developed by the US during the cold war in secrecy. The aircraft would have looked very much like a flying saucer, though it had severe overheating problems that prevented its practicality.

 

Snecma Flying Coleoptere

18ca57ys6ijsqjpg

The Snecma Flying Coleoptere was a French experimental aircraft that could take of and land vertically, removing the need for a runway.

 

De Lackner HZ-1 Aerocycle

The De Lackner HZ-1 Aerocycle was designed to take a single soldier into difficult-to-reach areas for reconnaissance missions.
