Integrated Aero-Servo-Thermo-Populso-Elasticity (ASTPE) for Hypersonic Scramjet Vehicle Design/Analysis

The ZONA Team proposes to establish an Aero-Servo-Propulso-Elastic (ASPE) methodology as a conceptual design/analysis tool for the stability and control of a Single Engine Missile (SEM) model, representing a generic hypersonic wave-rider with airbreathing/scramjet engine. With body flexibility included, the SEM formulation considers all physical components in order to capture the underlying physics that attribute to the coupling mechanism between aerodynamic, aeroelastic, propulsive and control forces. Generally applicable to such hypersonic vehicles, practical dynamic-inversion based control laws are proposed to design a single controller that will work automatically across the range of the SEM's mission profile while assuring robust stability and specified level of performance. A feasibility study will be conducted to validate the ASPE methodology at given flight conditions. The ASPE developed in Phase I will be modulized and fully integrated with ZONA's Hypersonic Aerothermodynamics, Aerothermoelasticity for TPS design/optimization (HyAAT) software system in Phase II. The outcome is an Enhanced HyAAT* system as a preliminary design and analysis tool with comprehensive Aero-Servo-Thermo-Propulso-Elastic (ASTPE) considerations. The ZONA team will work closely with the AF monitor throughout the course and will accept new vehicle definitions. The developed product HyAAT* is expected to enhance design/analysis capability of current and future hypersonic vehicles.
