Brief History of Aviation
The desire to fly has been present in humankind since ancient times. As early as 300 BC, the Chinese invented the kite, developing techniques to make it fly in the air and recording human attempts of flying with them.
Later, around 400 BC, a scholar of ancient Greece, Archites of Taranto, built a wooden artifact which he named “Peristera” (dove, in Greek). The bird-shaped apparatus, tied to ropes that allowed a controlled flight, was propelled by an air blast.
However, the credit for the first human flight, rests on the Andalusian Berber Abbas Ibn Firnas, born in Ronda (Malaga, Spain), who is said to have jumped from a high place in Cordoba in 875 with wooden wings covered with silk and feathers. Apparently, he flew for about 10 seconds before falling and breaking both legs. This flight served as an inspiration to Elmer de Malmesbury, a Benedictine monk who, a century later (about 1010) traveled more than 200 meters in

Autogyro
Rotorcraft with unpowered rotor
An autogyro (from Greekαὐτός and γύρος, "self-turning"), or gyroplane, is a class of rotorcraft that uses an unpowered rotor in free autorotation to develop lift. Part 1 [1] (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that gyroplane "means a rotorcraft whose rotors are not engine-driven, except for initial starting, but are made to rotate by action of the air when the rotorcraft is moving; and whose means of propulsion, consisting usually of conventional propellers, is independent of the rotor system." While similar to a helicopter rotor in appearance, the autogyro's unpowered rotor disc must have air flowing upward across it to make it rotate.
Forward thrust is provided independently, by an engine-driven propeller.
It was originally named the autogiro by its Spanish inventor and engineer, Juan de la Cierva, in his attempt to create an air
