TELEMETRY, COMMAND, AND BEACON ANTENNAS FOR VARIOUS AIR FORCE ROCKETS, PROBES AND SATELLITES.
Abstract
A number of measurements were made to improve existing antenna designs and to obtain information on antenna behavior during flight. Precision radiation patterns were run on unit radiators as well as various arrays to more fully evaluate antenna characteristics such as gain and directivity. Effects due to humidity were measured on various antennas by means of a humidity chamber. Aerodynamic heating was simulated by means of a jet engine exhaust. Effects of heating on antenna tuning and mechanical integrity were checked in this manner. Mechanical vibration of various antennas mounted in numerous modes gave valuable information for further mechanical improvement. Vacuum studies for rf breakdown characteristics were also run. The vacuum system is being redesigned and Physical Science Laboratory has furnished a vacuum pump of advanced design and a larger vacuum chamber for use in these tests. Field checkout of special flight antennas was performed at various launch sites.
