A Wind Tunnel Investigation of the Forces Acting on an Ejector in Flight.

Abstract

The lift and drag forces experienced by an ejector in a wind tunnel were measured and correlated with the geometry and static performance of the device. Lift forces in excess of three times the total static thrust are readily obtained at moderate tunnel speeds and with very little penalty in increased drag. Whereas the primary mass flowing to the ejector remained constant, pressure surveys at the exit plane of the ejector indicated a reduction in total pressure with increasing tunnel speed. (Author)
