ABSTRACT:
A sonobuoy is disclosed which has a linear array of hydrophones horizonta depolyable at sea by a metal hydride jet thruster. The thruster is powered by releasing hydrogen gas from iron-titanium hydride (FeTiH.sub.1.95) and igniting it in a mixture with oxygen generated by reacting sodium peroxide (Na.sub.2 O.sub.2) with the water. The hydride is activated by an electrical heater and the steam generated by the combustion of the hydrogen and oxygen mixture. The thrust is directionally controlled in azimuth and depth by a compass and depth sensor.
