NASP - Focus on technology

The major changes in the NASP program caused mostly by budget pressures are described and current technology developments are highlighted. Particular attention is given to the program funding, vehicle and engine design, and the technology program. It is concluded that the success of the X-30 vehicle design depends on the success of the technology development effort. The major accomplishments of the NASP technology program include the T-5 Shock Tunnel at California Institute of Technology and Mach 16 injection and mixing experiments conducted in this facility; the low speed component integration rig which provide data on engine operation from static conditions to Mach 3.5; the module to module interaction test which provided data on the effects of inlet unstart in one engine module on an adjacent module at Mach 4.3; and the direct-connect module used for fuel injection and mixing studies at Mach 6-8.

The first year of teaming - A progress report

The National AeroSpace Plane (NASP) national contractor team began formal operations on January 31, 1991, and made considerable progress toward demonstrating the feasibility of the X-30 and the technology readiness to enter a full-scale development program. Two cycles of conceptual design are complete, preliminary design is initiated, and many of the major configuration and structural arrangement decisions are complete. Results of work in supporting technology areas for a variety of the propulsion system technologies are mentioned, including the low-speed oxidizer system, the production of slush hydrogen, and the use of external burning. Results of tests currently being performed on structural demonstration articles are satisfactory. Each of these demonstration articles is representative of structures and materials to be incorporated into the team's X-30 design. An operating team is outlined that encompasses not only the five principal contractors and their subcontractors, but also government and university laboratories through an innovative arrangement that brings this work into the mainstream of the program.
