Abstract

Experimental investigations on the steady and unsteady aerodynamic forces were performed on a wing/ejector engine model in the subsonic flow regime. The pressure measurements were made for the following parameters velocity, angle of attack, mass flow, reduced frequency, and amplitude of oscillation of the engine performing pitch oscillations. For the wing/engine combination, the unsteady interference effects for engine oscillation on the pressure side of the wing are strongly affected by flow separation at the wing/pylon connection. The induced unsteady aerodynamic forces on the wing are small. The experimental results are ready to be compared with theories, which still must be developed for all necessary parameters.Problems with the test models, the test equipment, the measuring procedure, and the electronic data recording and processing are discussed.
