Engelbert Zaschka (1896 in Freiburg im Breisgau, Germany – June 26, 1955 in Freiburg im Breisgau, Germany) was a German chief engineer [Rolf Besser: Technik und Geschichte der Hubschrauber: Von Leonardo da Vinci bis zur Gegenwart. Bernard & Graefe Verlag, Bonn 1996, p. 65] , chief designer and inventor. [ [http://www.utdallas.edu/library/collections/speccoll/ltapdf/Rosendahl1.pdf The University of Texas at Dallas: "Vice Admiral Charles E. Rosendahl Collection - Biographical Information"] (See also: Charles E. Rosendahl)] Zaschka became one of the first German helicopter pioneers. He is a striking representative of the "Rotationsflugzeug" (Rotary-Wing Airplane). [Engelbert Zaschka: "Drehflügelflugzeuge. Trag- und Hubschrauber." C.J.E. Volckmann Nachf. E. Wette, Berlin-Charlottenburg 1936, p. 57]

Engineering Activities

Zaschka Helicopter

In 1927 [ [http://siris-thesauri.si.edu/ipac20/ipac.jsp?session=11P8B0B391935.82&profile=planes&uri=link=3100019~!26176~!3100001~!3100002&aspect=subtab13&menu=search&ri=2&source=~!sithesauri&term=Zaschka&index= Smithsonian National Air and Space Museum Washington: "Zaschka Helicopter (1927)"] ] 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. Gliding in this case means a straight descent. He wanted to develop an efficient propeller drive. [Engelbert Zaschka: "Drehflügelflugzeuge. Trag- und Hubschrauber." C.J.E. Volckmann Nachf. E. Wette, Berlin-Charlottenburg 1936, p. 47] A swivelling propeller at the rear provided propulsion and rudder control. The machine was a combination of an autogyro and a helicopter. 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.

Zaschka Human-powered aircraft

In 1934 [ [http://siris-thesauri.si.edu/ipac20/ipac.jsp?session=11P8B0B391935.82&profile=planes&uri=link=3100019~!26176~!3100001~!3100002&aspect=subtab13&menu=search&ri=2&source=~!sithesauri&term=Zaschka&index= Smithsonian National Air and Space Museum Washington: "Zaschka Human-Power Aircraft (1934)"] ] he completed a large human-powered aircraft, the "Zaschka Human-Power Aircraft". Zaschka constructed the large human-powered tractor monoplane with a narrow wing spanning about 66 feet (20 metres).

Motorcycle and Zaschka Three-wheeler

From 1921 till 1925 the design department of "Orionette AG für Motorfahrzeuge" in Berlin [Otto Meibes: "Die Entwicklung der deutschen Automobilindustrie." Halle 1926, p. 166] , headed by Engelbert Zaschka, also produced some interesting unorthodox designs. [ [http://members.chello.nl/~wgj.jansen/text/orionette.html "Orionette" - Unfortunately the very desmodromic lay-out of this interesting two-stroke engine still remains secret. Source: Motorrad Heft 10/1971 and Tragatsch, E. : The Ill. Encyclopedia of motorcycles.] ] Orionette is a historic German motorcycle brand.

In 1929 he invented a three wheeled car, an automobile which could be assembled quickly in domicile or set aside.
