Nasa's Top Secret Inventions Have Just Been Revealed

Recently, NASA has published many videos of tests of its top secret inventions to the public. Those are the unsuccessful and 'weird' inventions that have always been kept secret by NASA.

Key Facts About Nasa

On April 25, 2001, NASA experimented with aircraft using an inflatable impeller technology.

The wings of the aircraft are inflated with nitrogen oxide gas. Later, the experimental aircraft was dropped from a mother ship at an altitude of 245 - 305 meters and landed safely safely.

In 1969, the machine was built to equip the Apollo 11 ships on the Moon at the end of the year.

Why Nasa Matters

'Multiple leg spiders' are used to move if the terrain on the surface of the Moon is too dangerous. In the clip, "iron spider" floated in the air easily.

NASA's first solar plane has a 74-meter wingspan, longer than Boeing 720. It is made up of carbon fiber, epoxy, Kevlar, foam and a thin transparent plastic skin. This aircraft was tested in 2003.

Hyper III is NASA's wingless model, using the fuselage to increase aerodynamic capabilities, its wings are very small and do not have an important role in flight.

The video records the process of testing the release of Hyper III from a NASA-controlled SH-3 helicopter in December 1969.
