Application of the Small Body Pressure Transducer

Abstract

The small body pressure transducers were used in both fixed-wing and rotary-wing scale models to measure dynamic and static pressures. These models were then tested under controlled wind tunnel conditions and the transducer signals recorded for either on- or off-line analyses. One experiment using the small body pressure transducers was conducted in the American Aeromechanics Wind Tunnel in order to compare different geometrically shaped rotary-wing airfoil sections under dynamic stall conditions. An additional application for the small body pressure transducer was a series of tests conducted in both the French Tunnel, Saclay, France and the Dutch-German Amsterdam, The Netherlands wind tunnel. During the foreign tests, data were obtained on helicopter rotor noise generated by blade pressure disturbances due to helicopter blade-vortex interaction. Both the acoustic signature and the blade pressure transducer outputs were recorded simultaneously.
