SUBMARINE-RESCUE VHF/UHF RADIO TRANSMITTING BUOY, MECHANICAL DESIGN CONSIDERATIONS
Abstract
A radio resue buoy was developed which can be launched from the interior of a submerged submarine in distress. The buoy rises to the surface and automatically transmits a radio distress signal continuously on 243 mc. With radio direction-finding techniques, it serves to localize the area. Physical characteristics and mechanical design features are considered in terms of the limitations imposed by requirements for simple ejection, automatic operation, stable flotation, reliability of operation after long stowage, minimum maintenance, and ease of manufacture in quantity procurement. Operating life is more than 11 hours at full output of one-half watt. Estimated shelf life is in excess of 10 years. Radio-communication ranges have been achieved to essentially line-of-sight with surface vessels, and with aircraft to distances of 36, 52, and 82 naut mi at respective aircraft altitudes of 2,500, 5,000, and 10,000 ft.
