Control Centric Parametric Trade Studies for Scramjet-Powered Hypersonic Vehicles

This paper presents an overview of a modeling and analysis tool suite for supporting early stage design of scramjet powered hypersonic vehicles. This efiort is a part and parcel of NASA’s Hypersonic project aimed at development of tools and methods for designing the next generation of space access vehicles. The tool suite, known as Aerospace Vehicles Simulation and Analysis Program for Hypersonics (ASAP-Hypersonics), is designed to provide rapid modeling and analysis capability from a GNC view point. The primary focus of ASAP is to provide the capability to generate GNC-centric constraints for use in early stage vehicle design studies. The modeling and analysis capabilities of ASAP-Hypersonics are demonstrated using some example trade studies. ASAP-Hypersonics can be used in various modes of operation including modeling, dynamic analysis, control analysis, parametric trade studies, and vehicle optimization.
