Popis: The Hypersonic International Flight Research and Experimentation (HIFiRE) program is a joint effort between the United States Air Force Research Laboratory (AFRL) and the Australian Defence Science and Technology Organisation (DSTO). Boeing is an industrial partner in the HIFiRE program. The specific objective of HIFiRE flight experiment number four (HIFiRE-4) is to gather flight data on the aerodynamics, stability, and control of an advanced waverider configuration performing a pull-up maneuver from a near vertical atmospheric entry flight path angle to horizontal flight. This paper discusses the design approach of this low cost airframe for flight test. The HIFiRE-4 vehicle flight profile presented additional challenges in airframe design that are different from a ballistic entry. The HIFiRE-4 airframe is constructed of conventional metallic materials including aluminum and copper. It is highly desirable to have a fully three dimensional thermal and structural analyses to verify the integrity of the airframe design, particularly the sharp leading edges which were subject to high aerodynamic heating. This paper describes how a cost effective integrated design development and flight test methodology was employed to attain challenging technical objectives within budget constraints typical of a basic research activity.
