IN-FLIGHT THRUST REVERSERS FOR TACTICAL FIGHTER APPLICATIONS.
Abstract
This program was to model test, analyze, and design a thrust reverser for use on tactical aircraft. The reverser is intended to replace speed brakes and drag chutes currently in use as decelerating devices. The program was divided into twelve areas of investigation. These areas of investigation encompassed design, performance analysis of both the reverser and the reverser aircraft combination, loads analysis and both cold flow and hot gas model testing. A target type reverser was selected in the design study, and all the testing proved that reversal efficiencies of from 50 to 60 percent could be obtained through pressure ratios of 1.3:1.0 and 4.0:1.0. A method of eliminating reverse ejector flow was determined. Performance loss caused by the reverser installation was found to be negligible. It can be concluded that a thrust reverser is feasible for use on supersonic aircraft for inflight decelerations over and above those normally provided by speed brakes or drag chutes. The reverser installation will not cause adverse effects on the performance of the aircraft. It is recommended that a flight test program be initiated utilizing the concept derived in this study. This flight test program would substantiate the use and need for a thrust reverser on tactical aircraft as well as prove the structural concept chosen in this study. (Author)
