NASA LaRC Solicitation: Analysis of Ares 1 Thrust Oscillation Issues, NASA

"NASA/LaRC has a requirement for Use of the proprietary Universal Combustion Device Stability (UCDS) process developed and owned by the Gloyer-Taylor Laboratories LLC. The Government must assess thrust oscillation issues with the Constellation Program's ARES five-segment solid rocket booster. The Gloyer-Taylor Labs UCDS is a breakthrough modeling and analysis process, which provides detailed physical insight into the stability characteristics of complex combustion devices. Using calculations that are based entirely on known or measurable parameters, the UCDS makes it possible to predict for a given initial state the actual wave geometry, time history of the wave amplitude, limit amplitude reached by the wave system, and accompanying changes in the combustion chamber state properties. Design of corrective procedures can be accomplished with full physical understanding of the action of damping mechanisms."
