Thrust reversing effects on horizontal tail effectiveness of twin-engine fighter aircraftThe Langley Research Center has conducted an experimental program to determine the interference effects of thrust reversing on horizontal tail effectiveness of a twin engine, general research fighter model at approach (Mach number 0.15) and in-flight (Mach number 0.60 and 0.90) speeds. Twin vertical tails were tested at three longitudinal locations. Two nonaxisymmetric nozzle reverser concepts were studied. The effects of thrust reversing on horizontal tail effectiveness were found to be very dependent upon vertical tail locations. At approach speeds thrust reverser operation usually resulted in large variations in horizontal tail effectiveness as either nozzle pressure ratio or model angle of attack was varied. Either increases or decreases in tail effectiveness ocurred due to reverse operation depending upon tail location. At in-flight conditions there were always decreases in tail effectiveness due to reverser operation regardless of vertical tail location.
