Sharp-B01: An Important Element of NASA's Launch Vehicle Development Program

Sharp body designs for future reusable launch vehicles offer a number of attractive features including allowing zero staging, enabling airbreathing and lofting ascents, and potentially providing global cross range re-entries with continuous communications. The Slender Hypersonic Aerothermodynamic Research Program (SHARP) was initiated by NASA Ames to demonstrate sharp, passive leading edge designs for hypersonic vehicles, incorporating new ultra-high temperature ceramics. This paper will discuss how SHARP will provide an important technology base for making sharp body hypersonic vehicle designs a reality, and how this activity fits into NASA's overall program for developing next generation reusable launch vehicles.
