Abstract : A beacon system was designed and tested for use in recovering rockets and data stored therein. A miniature radio beacon is carried aloft with the rocket and ejected just before rocket impact. The beacon capsule impacts near the rocket, erects an antenna, and transmits a direction-finding signal at 242.00 Mc=0.005 percent for an estimated 10- to 16-hr period. Tests show that the beacon can withstand rugged flight environment, including high-speed release from altitudes exceeding 1000 ft above ground and subsequent 4000-g impact against rocky terrain. Theoretical aerodynamic and ground-impact investigations were performed, simulated flight and impact tests were conducted, and numerous electronic and mechanical instruments were developed. (Author)
