Testing an Anti Tank Missile Model with Jet Simulation in the T-35 Subsonic Wind Tunnel
Goran Ocokoljić Boško Rašuo
In this paper, the wind tunnel test results of an Anti Tank Missile Model (ATM) with and without thrust vector control (TVC) jet simulation are presented. Since the lateral jets have influence on missile aerodynamic characteristics, the aerodynamic coefficients of the missile with lateral jets have to be known. This is especially important in the process of defining an accurate and efficient guidance algorithm. The main task of these experiments was to provide an experimental data base for the estimation of real effects of jets. A high pressure air installation for the jet simulation in the wind tunnel test section was described. The analysis was presented for Mach number 0.2, model configurations with and without jets, and three jet tab positions: tabs out of the jets and the upper or lower tabs in the jets. The experimental results are presented by the normal force and the pitching moment coefficients. The results obtained by flow visualization with tufts are also shown.
