ABSTRACT:
To prevent the accumulation of a gas bubble at the inner end portion of a torpedo tube, exhaust gases are not discharged from an improved torpedo until after the torpedo has moved out of the torpedo tube. The improved torpedo includes a gas powered engine which rotates a hollow drive shaft to effect rotation of torpedo drive propellers in a known manner. During operation of the engine, there is a continuous flow of gas through the engine into the hollow drive shaft. When the torpedo is in the torpedo tube, gas is conducted from the hollow drive shaft through a manifold to a storage tank. Water which may accumulate in the hollow drive shaft is centrifugally slung outwardly against the side wall of the rotating drive shaft. Tubes extend through the water to a central portion of the drive shaft so that the gas can be conducted through the water in the shaft to the manifold and storage tank. When the torpedo has moved out of the torpedo tube, the pressure of the stored gas causes a valve to open and gas is discharged from the torpedo through the drive shaft and valve.
