A Preliminary Windtunnel Investigation of a Wing Tip Static Pressure Amplification Device,

Abstract

A series of windtunnel investigations of a model utilizing a variety of ducted wing tip sections was conducted in the Princeton University 4' x 5' windtunnel during September and October 1974. The ducted section consisted of a venturi entry portion that could be tested with a number of different discharge slots of various geometries. The tests showed that significant amplification of the free stream static pressure could be achieved; that in general the magnitude of the amplification factor decreased with angle of attack; the magnitude of the factor could be significantly affected by the location and shape of the exit slot; and that the nature of the resulting signal was influenced by the location of the entry slot with relation to the leading edge.
