Abstract

Wind tunnel tests were carried out on 1:50 scale PSLV_XL configuration in the Mach number range of 0.8 to 3.0 to determine the repeatability of basic aerodynamic characteristics of the complete configuration at model roll orientations of 0 deg, and -90 deg. The tests were conducted in the NAL 1.2m wind tunnel in the Mach number range of 0.8 to 3.0 and in the incidence range of -8 deg to 8 deg. To ascertain the repeatability of the data with different support systems, few repeat runs were conducted on the complete configuration with regular as well as TRMS support system at selected Mach numbers in the transonic regime. Repeatability tests were also carried out on 1:50 scale PSLV-C configuration without RFDS protrusions at Model roll of 0 deg and -90 deg with new and the old rear segments. A few tests were also conducted on 1:40 scale PSLV D1 protrusion model to check the repeatability. The Reynolds number based on body diameter varied from 1.1 to 1.7 million.
