Ground Test and Evaluation Methodologies and Techniques for the Development of Endoatmospheric Interceptors

The cornerstone of the Strategic Defense Initiative SDI is the development of ground-based interceptors for late mid course and terminal tactical and strategic missile defense. Kinetic energy-type interceptors for ballistic missile defense have evolved from command guided concepts with nuclear warheads such as Nike Zeus in the early 1960s and SPRINT and Spartan in the late 1960s and early 70s. The family of Theater Missile Defense TMD and National Missile Defense NMD interceptors currently under development make up the national initiative of providing Global Protection Against Limited Strike GPALS. Selection of a ground-based interceptor airframe design is an iterative process that compromise among aerodynamic, aerothermal, weathererosion, and lethality requirements. The design validation process requires high quality ground test data to validate engineering designs, simulation and control models, material and component performance, and lethality assessments. This paper will focus on capabilities and test techniques of the AEDC facilities which are applicable to the development of ground-based interceptors. Also, a brief overview of the AEDC test support service and capabilities and supersonichypersonic related technology programs will be provided.
