Steady and Periodic Pressure Measurements on a Generic Helicopter Fuselage Model in the Presence of a Rotor
Abstract
Helicopter airframes are subjected to periodic air-loads due principally to the rotating main rotor blades. The periodic air loads impact the noise and vibration within the passenger cabin as well as the fatigue life of the airframe. Computational techniques have been and are being developed to predict these periodic airframe air loads. Periodic pressure measurements are needed on simple configurations for validation of the computational techniques. Few experimental data sets are available in the open literature. Available results are typically limited to a few measurement stations and test conditions. The purpose of this investigation is to obtain steady and periodic pressure distributions on a generic helicopter configuration suitable for CFD validation studies.
