Aerodynamic and Inlet Characteristics of the HAST I and II Missiles at Mach Numbers 0.5 to 1.6
Abstract
The aerodynamic and inlet characteristics were investigated for 0.15-scale models of the HAST I and II missiles. Mach number was varied from 0.5 to 1.6 for the HAST I test phase, but the HAST II models were tested only at Mach number 1.6. Reynolds number based on model length, varied between 13.9 and 18.7 million. Data were obtained on the HAST I for canard deflection angles from -20 to 20 deg, aileron deflection angles from 0 to 10 deg, inlet capture area ratios from 0 to 1.2, angles of attack from -4 to 12 deg, and sideslip angles of 0 to 6 deg. Data were obtained on the HAST II at angles of attack from -4 to 4 deg with canard deflection angle, aileron deflection angle, and sideslip angle all zero. Also characteristics of 18 HAST I and six HAST II configurations were evaluated. Test results indicated that canard deflection significantly affected axial-force, pitching-moment, and trim characteristics while aileron deflection affected only the rolling-moment characteristics. The inlet performance parameters showed significant variation with changes in capture area ratio and free-stream Mach number.
