Introduction •
•
•
Ever since man made his first flight on Dec 17th 1903 . The field of aviation has seen many innovations and major developments. Aerospace structures include launch vehicles, (GSLV, Delta, Titan), missiles (BRAHMOS, Harpoon), Hypersonic vehicles (Space Shuttle), military aircraft (TEJAS, F-18) and commercial aircraft (Boeing 777, MD-11), gyroplanes, gyrocopter,jetcopters. Functions of aerospace structures include travelling, space exploration, emergency services, military applications, logistics etc.

Gyroplane •
•
It has a fuselage like an airplane, and a propeller to provide the propulsion, but its lift is provided by a rotor similar to that in a helicopter.
The difference is that the rotor in an autogyro is not powered. It is made to spin by aerodynamic forces. This is known as autorotation.
