Abstract

Wind tunnel investigations were undertaken to study the separation characteristics of four strap-on boosters simultaneously separating from the core of a launch vehicle. Tests were conducted in the NAL 1.2-m trisonic blowdown wind tunnel at a freestream Mach number of 3.1 and a test Reynolds number of 30.5xD7;106 m-1. Force data from all the four boosters were obtained for a range of pitch angles between -3 and 3 deg. Data corresponding to the highest value of the pitch angle in flight were utilized for the trajectory computations.
