SRB environment evaluation and analysis. Volume 1: Redesigned SRB flight heating evaluation

Abstract

Following the Space Shuttle STS-51L disaster on January 28, 1986, a considerable redesign effort was launched on the Solid Rocket Booster. This effort culminated in three instrumented flights, STS-26R, 27R, and 29R, beginning in September of 1989. Aeroheating data were obtained on these flights in the form of pressure, heat flux, and gas temperature probe measurements. These data were analyzed from an ascent and reentry heating point of view. The flight data were verified, compared with historic and theoretical results, and scaled to design. Impact of these results on the current design environment set was assessed and recommendations made. This report documents this effort.
