Abstract:
With the advent of VTOLSTOL aircraft, it has become increasingly necessary to expand our knowledge in the field of low-speed aerodynamics. At the present time there is an appalling lack of experimental test data applicable to this type of high power-to-weight ratio aircraft. As a result, analytical work on evaluating simple static stability derivatives is almost non-existent and most of what has been done has not been confirmed nor correlated with test information. The Subsonic Aerodynamics Laboratory of Princeton University, in co-operation with the Airship Test and Development Department, NAS, Lakehurst, has developed a Flying Wind Tunnel, utilizing a Navy ZPG-2 airship as the stable model carriage. The airship has been modified to serve as the inflight laboratory and data reducing center for such inflight model testing. Models are flown beneath the airship and the data received, reduced, and analyzed inflight in this laboratory. This airship as a flying wind tunnel has been shown to give accurate, repeatable data for a variety of configurations with no difficulty. Author
