Design-oriented models to optimize scramjet and multi-mode engines
Abstract
The objective of the proposed work is to improve understanding of dual-mode scramjet isolators operating in ram-mode and to develop a dynamic physics-based reduced-order model (DPB-ROM) that will serve as a useful tool to aid their design. This delivered ROM will be able to predict the shock train motion in the presence of time-varying pressure disturbances such as combustor pulsations or atmospheric disturbances. To ensure rapid development, we will leverage previous work to the fullest extent possible; in particular, the starting point will be our existing quasi-steady method to locate the shock train based on the ratio of the isolator outlet to the inlet pressures, and the Mach number gradient in the full started isolator
