An Investigation of Wing Lift Augmentation with Spanwise Tip Blowing.

Abstract

Experimental and analytical investigations or lift augmentation on fighter type wings with wing tip blowing are described. Results of a small-scale wind tunnel test program in the NEAR, Inc. facility are presented for three wings with a wide range of tip nozzle configurations. Effects of nozzle geometry and blowing rate are described, and optimum tip nozzles are selected for further examination in a large-scale test. Results from a large scale test program in the 7- by 10-foot wind tunnel at the NASA/Ames Research Center are presented for a typical fighter wing with tip blowing. Effects of tip nozzle geometry and blowing rate on lift and drag augmentation, measured pressure distributions, and flow field surveys are discussed. Keywords: Lift augmentation, Numerical analysis, Wing tip blowing.
