Charles Horton Zimmerman (1908 – May 5, 1996), was an
aeronautical engineer
, whose work on novel airfoil configurations led to several notable experimental aircraft programs.
Early work
Zimmerman worked at
Vertical/Short Takeoff and Landing
aircraft.
Novel Flight Vehicles
Zimmerman's research[5] posited aircraft having flat circular bodies, sans wings, as their lifting surface. In the 1940s, Zimmerman and the Navy began researching this idea, which led to the Vought XF5U, nicknamed the "flying pancake".
In 1953, Hiller Aircraft contracted with the Office of Naval Research to combine several research ideas, including Zimmerman's "kinesthetic" theory, to produce an airworthy "flying platform". The project was classified and conducted at Hiller's Advanced Research Division. In 1954, the prototype model 1031 was delivered. A 1956 Army contract produced the larger
VZ-1 Pawnee
.
Awards
- Wright Brothers Medal in 1956[9]
- Dr. Alexander Klemin Award in 1956 from the American Helicopter Society
