RA-3B/Sonobuoy Separation Program.

Abstract

An analytical and empirical examination of the separation of sonobuoys from the modified RA-3B FuNo. 144833 is presented. A sonobuoy launcher which simulates buoy deployments from the S-3A aircraft has been installed in the RA-3B to provide a capability to test the most severe S-3A launch conditions. A digital computer program was used to examine separation trends and identify configurations to be flight tested. Sonobyoys equipped with parachutes or rotochutes and heavier unretarded buoys with a forward located center of gravity were found to separate safely from the RA-3B at speeds at 425 KIAS. Maximum safe deployment speeds are lower for lighter unretarded sonobuoys, or those with a more centrally located center of gravity. Expressions for the ejection velocity from the RA-3B launchers are also derived.
