Reaction Jet Control Effects on the Air Force Advanced Tactical Rocket at Mach Numbers 2, 3, 4, and 5

Abstract

This program is part of a study to provide the Advanced Tactical Rocket (ATR) under development by the Air Force Armament Laboratory with a jet reaction control system (RCS). This control system, consisting of four sets of six supersonic nozzle jets, will be used to make final corrections to the ATR trajectory. The wind tunnel study was conducted at Mach numbers 2, 3, 4, and 5 using a 4/7-scale model of the ATR with a set of six sonic mozzles to simulate, with air, the jet wake disturbance produced by the full-scale RCS. The tests were conducted with the RCS placed at two different axial positions along the model axis and at roll angles of 0 and -45 deg with respect to the vertical tail fins. The data consisted of 5-component force (excluding axial force) and moment data. The model angle of attack was varied from -12 to 12 deg, and model roll angle was varied from 0 to -90 deg. The disturbance generated by the RCS simulation produced significant rolling moments when the model was in a combined pitch and roll attitude. Also, the slope of the aerodynamic coefficients with angle of attack varied depending on the RCS jet conditions and model roll position.
