Advanced Reusable Launch Vehicle (RLV) Systems Technology Qualis Corporation Huntsville, AL

1. Advanced Reusable Launch Vehicle (RLV) Systems Technology Qualis CorporationHuntsville, AL Innovation Defined the techniques and model hardware innovations for a new class of short duration base heating tests that are an order of magnitude cheaper to develop and operate than previous tests of this type. • Accomplishments • A 2.25% scale model of the X-33 flight demonstrator has been successfully hot fired. The model simulates the propulsion system hot exhaust gases for the X-33, and provides data which are useful in quantifying and validating the thermal environment in the aft end of the vehicle during powered flight. • Nitrogen buffer gas delivery system and fast acting electrically actuated propellant valve capability has been demonstrated. • Commercialization • The hardware and testing method will be marketed to Launch Vehicle prime contractors to support their development of the RLV, Expendable Launch Vehicles and Air Breathing Reusable Launch Vehicles. • A simplified set of test hardware will be offered along with the instructional software as a teaching aid and research tool for mechanical, aerospace, and propulsion departments at Universities. X-33 Base Model with Oil Flow Visualization X-33 Model Plume High Speed Film • Government/Science Applications • X-33 Plume induced convective heating and base pressure environment definition. • Potential application to RLV and future launch vehicles. • A Phase III contract will assist in conducting X-33 high altitude testing in MSFC Nozzle Test Facility. • Phase II was up to 10X cheaper than STS Test.
