AN/URT-21 LOCATOR BEACON JUMP TEST AND RECEPTION DISTANCES,

Abstract

The AN/URT-21 Locator Beacon and riser antenna were installed in several different locations in the B-5 Back Style and AP28S-10 parachutes. Live and dummy drop tests were conducted at altitudes of 1500 to 5000 feet in temperatures of -5F to 29F. Monitoring stations at a distance of 2 to 28 miles from the drop zones reported signals heard from time of parachute deployment until ground contact was made. Air-crew members wore the back style parachute with the beacon installed between the pack tray and back cushion. A study of their subjective evaluation of the comfort of this parachute was conducted in F-102, B-47 and KC-135 aircraft. After simulating ejection procedures and flying duties, aircrew members reported very minor or no discomfort and no interference with flying duties. It is recommended that beacons be installed between the pack tray and back pad, that the beacon activating button be made of rubberized material, and that the activating cord be tied on the riser.
