Piranha Wind Tunnel Test

Abstract

This report presents results from wind tunnel tests of several air duct-turbine wheel designs for the Piranha air-deliverable underwater mine (BLU- 94). The tests were conducted to determine the optimum turbine wheel blade angle for maximum rotational speed and acceleration, and to verify that the highest performance obtained would be sufficient to operate a portion of the mine's Safety and Arming mechanism. Maximum rotational speed developed with the optimum blade angle of 40 deg was 147 revolutions per second at an angle of attack of 10 deg and a free stream speed of 60.5 m/sec. Safety and arming mechanism function was obtained twice during the test.
