Effect of Nozzle Configuration on PDE Performance

The research was conducted at several levels of complexity in a hierarchical manner to establish its accuracy and reliability (1) supersonic inlet dynamics (2) detonation in single-tube, multicycle environments and (3) system performance and thermodynamic cycle analysis. The progress made in each of the above three areas was reported at the 14th U.S. Office of Naval Research (ONR) Propulsion Meeting [1]. The work performed focused on the following three areas (1) effect of nozzle configuration on PDE performance, (2) single-tube thrust chamber dynamics, and (3) multitube thrust chamber dynamics.
