In 1927[4] Engelbert Zaschka of Berlin built a helicopter, equipped with two rotors, in which a gyroscope was used to increase stability and serves as an energy accumulator for a gliding flight to make a landing. Berlin is the capital city and one of sixteen states of Germany. A helicopter rotor is the rotating part of a Helicopter which generates an aerodynamic Force. A gyroscope is a device for measuring or maintaining orientation, based on the principles of Angular momentum. Gliding is a Recreational activity and competitive Sport in which pilots fly un-powered aircraft known as Gliders or sailplanes Gliding in this case means a straight descent. He wanted to develop an efficient propeller drive. [5] The machine was a combination of an autogyro and a helicopter. Configuration An autogyro is characterised by a free-spinning rotor that turns due to passage of air upwards through the rotor History Since 400 AD Chinese children have played with bamboo flying toys. The principal advantage of the machine, Zaschka says, is in its ability to remain motionless in the air for any length of time and to descend in a vertical line, so that a landing may be accomplished on the flat roof of a large house. In appearance, the helicopter does not differ much from the ordinary monoplane, but the carrying wings revolve around the body. In 1934[6] he completed a large human-powered aircraft, the Zaschka Human-Power Aircraft. A human-powered aircraft (HPA is an Aircraft powered by direct human energy and the force of Gravity; the Thrust provided by the human may be the
From 1921 till 1925 the design department of Orionette AG für Motorfahrzeuge in Berlin[7], headed by Engelbert Zaschka, also produced some interesting unorthodox designs. Aktiengesellschaft ('aktsiəngəzεlʃaft abbreviated AG) is a German term that refers to a Corporation that is limited by shares i [8] Orionette is a historic German motorcycle brand. MotorCycle is the title of a 1993 album by Rock band Daniel Amos, released on BAI Records.
In 1929 he invented a three wheeled car, an automobile which could be assembled quickly in domicile or set aside. A three wheeled car, also known as a tricar or tri-car, is an Automobile having either one Wheel in the [9]
