DISCOVERER. Range Safety Report No. 5

Abstract

The Range Safety requirements established by the Vandenberg AFB Range Safety Officer are discussed herein, as are the means adopted by LMSD to comply with these requirements. In addition, the aerodynamic and trajectory data required for range safety evaluation are presented. Calculations indicate that the Discoverer/Thor configuration cannot execute a trimmed turn; therefore, maximum-rate controlled turns are presented to comply with the Vandenberg AFB Range Safety Officer requirements. The maximum-rate controlled turn is the sharpest turn that the missile can execute and still remain under control. (Controlled turns could be programmed by gyro drift and/or error in the programmer.) Because of the nature (cyclic) of a tumbling turn, the maximum velocity vector rotation is determined for the first one-half cycle of tumble. Further investigation shows that the worst case exists during the first 20 seconds of flight.
