Abstract:

Telemetry systems capable of surviving gun-launched accelerations in the order of 60,000 g have been developed for the High Altitude Research Program HARP. Such telemetry systems have been used to provide data on the flight dynamics of gun-launched vehicles as well as measurements of upper atmospheric phenomena. The results of measurements of electron densities and temperatures in the upper atmosphere are presented and discussed as examples of the data gathering capability of the HARP program. Vehicle roll rates and pitch-yaw frequencies have been measured during high altitude flights. The results are presented and some anomalous examples are discussed. It has been shown that the technique of using guns to launch instrumented payloads into the upper atmosphere is both practical and useful. Moreover, the inclusion of on-board instruments to observe the dynamical behavior of flight vehicles provides a useful tool for aerodynamic research in the real atmosphere. Author
