FURTHER DEVELOPMENTS IN LOW-SPEED WIND-TUNNEL TECHNIQUES FOR V/STOL AND HIGH-LIFT MODEL TESTING

Abstract

Experimental methods for wind-tunnel testing of high-lift models with boundary-layer control and circulation control were previously described by the authors about four years ago. Some of the further advances since then, particularly those to expedite investigations on jet and fan lift models at RAE, are discussed. Attention is concentrated on the following topics: (1) special mechanical and strain-gauge balance rigs for jet-'blowing models; (2) engine exit and intake flow simulation at model scale; and (3) ground simulation by a moving-belt rig. The need, development and application of these techniques are considered, together with some problems still to be overcome.
