Drag of shroud deployment bladder at Mach numbers of 8 to 20

STRACT’ An investigation ‘of a Shroud Deployment System (SDS) bladder was conducted in the Rensselaer Polytechnic Institute 2+in .Hypersonic Shock Tunnel. The cut-rem investigation experimentally determined the axial drag coefficient for the bladder, while attached ~0 .$he SDS d-ge support, for nominal Mach numbers of 8 to 20 and stagnation temperatures up to 7400 “R Me&ements were made of the pitot pressure and the force applied to the bag by the j~ypynjc: ,flqw. i 10..
