The factors that significantly affect the operability of aerospace planes are identified and considered in terms of the development of the National Aerospace Plane (NASP). The aircraftlike vehicle can be affected by variables related to the structure, propulsion, and mechanical elements of the design. The requirements to control the factors are listed including robustness, fuels and propellants, maintainability, autonomy, and development testing. The details of the requirements indicate critical factors such as the strength-to-weight ratios of the materials, propellant-system components that can withstand 5000 consecutive cycles, and low vehicle-failure probabilities. The NASP program is concluded to require: (1) models for quantitative operational assessments; (2) a modular design for the NASP structure; (3) computer-technology integration; and (4) technologies to support and normalize cryogenic operations.
