Abstract
The objective of this study is to effectively model and independently analyze the three dimensional forebody, inlet, and isolator of a conceptual Four-Point-Star Morphing Ramjet-Scramjet Engine. The analysis was conducted using computational fluid dynamic (CFD) softwares, namely, the Air Vehicle Unstructured Solver (AVUS) and FLUENTTM . Ultimately a steady, three dimensional, double precision solver was used to model and analyse this very complex problem. The morphing ramjet-scramjet engine is very unique in that, this engine actually changes its geometry to obtain optimal thrust efficiencies. This engine is capable of operating in many different propulsion regimes. The propulsion regime of interest to this study is the lower hypersonic regime. During this study, the geometry designed for a Mach 6 flowfield design was generated and analyzed to represent the propulsion regime. FLUENT was used to conduct a 2-D viscous study. The initial result revealed that the concept developed was very promising. Results produced from the 3-D viscous analysis were inconclusive due to limitations on the computing packages. AVUS was used to conduct a 3-D viscous study. Results obtained from the 3-D inviscid study were also very promising.
