TANDEM CASCADE THRUST VECTORING RESEARCH PROGRAM.

Abstract

Continuous thrust vectoring from horizontal through vertical, to reversed thrust can be accomplished by the use of one or two cascades in series, each employing variable camber airfoils. An experimental wind tunnel evaluation of three types of variable camber airfoils, and experimental scale model investigation of the principle applied to a cruise fan is reported. Flexible camber blades are found to be most satisfactory with a cascade pressure loss coefficient of 0.4. The tandem cascade system provides efficient thrust vectoring varying from 6 percent loss at 67 degrees vectoring, 12 percent loss at 124 degrees vectoring and a maximum of 54 percent reversed thrust. The application of this thrust vectoring system to V/STOL applications is encouraged by these results.
