Engineering slide rule Keuffel & Esser Co., New York, New York Summary George Rosen (1914-2004) graduated from MIT in 1937 and went to work for Hamilton Standard (now United Technologies Aerospace Systems) as the company's first propeller aerodynamicist. Summary In 1961, he received the United Aircraft Mead Medal in recognition of his work in the field of propeller aerodynamics and outstanding contributions to United Aircraft. Summary In 1975, Rosen received the Goddard Award for leadership and technical contributions in the engineering sciences of propulsion from the American Institute of Aeronautics and Astronautics (AIAA), for his contributions which included the integration of the propeller with modern turbine and turboprop engines, work on the propeller system for the Lockheed C-130 Hercules transport, the Q-Fan® high bypass ratio propulsion system developed for short take off and landing aircraft, and the variable-camber propeller for tilt-rotor aircraft. Summary In 1977, Rosen retired from his position as Hamilton Standard's chief of propeller research and development Summary In 1984, Rosen's history of the airplane propeller, Thrusting Forward, commemorated the 50th anniversary of the joint efforts of Hamilton Standard and the British Aerospace Dynamics Group. The book is one of the few histories dedicated to the aerial propeller. Credit Line Gift of George Rosen Inventory Number A20080398000 Type EQUIPMENT-Miscellaneous ______________________
