Abstract
This program entails designing a Mach 10, scramjet propelled missile system using advanced CFD and design-optimization tools. The CFD codes were validated using full-scale data sets obtained from tests performed in the LENS shock tunnel facility. They contain advanced turbulence and thermochemical models. A preliminary rocket boosted and scramjet propelled concept vehicle will be designed meeting Army requirements and constraints. The propulsive system design will use extensions of earlier concepts, including optimized inlet designs of Candler, and elliptical combustor designs of CRAFT Tech, containing optimized flush round/diamond injector patterns. Inlet/combustor/nozzle designs will be coupled (i.e. realistic inlet solutions are used at the combustor entrance, etc.), and, nose-to-tail CFD calculations will be performed to extract key performance parameters from the CFD for design evaluation. Formal optimization tools will be used to maximize on-design performance, and off-design performance (angle-of-attack, variable M) will be evaluated. The completed propulsive system design will be modified to improve aerodynamic performance (via modifying cross-section shapes, etc.) and additional lift will be obtained by aerodynamic extensions to the design. An optional task deals with the design and evaluation of start-up concepts which will be evaluated using transient CFD simulations.
