The IHAT System is a tool suite for configuration optimization of high speed airbreathing flight vehicles currently under development. The focus of the System is on high speed tactical weapons (Mach 4-8 regime) with relatively long range. The hypersonic flight regime of the weapons results in unique requirements for the analysis, design, and optimization tool suite. Due to the highly integrated nature of the configurations, traditional “stovepipe” design methods have not been successful in defining a viable configuration for this type of mission.

The IHAT System is an effort to provide an integrated analysis/optimization toolset. IHAT is being developed by a government/industry team using multiple, incremental builds. This paper discusses the IHAT development process and describes the capabilities of Build 4 of the IHAT System, which includes Modules for addressing the disciplines of Aerodynamics, Propulsion, Trajectory, Thermal, Structural, Stability & Control, Sensors, Lethality, and Cost Index.
