Abstract : A design study was made to improve the initial lock of the M20 thruster to prevent premature release (resulting from shock and impact) and rotation of the threaded end cap with respect to the outer body. Two designs were prepared, fabricated, and evaluated. The final thruster design was designated 'Thruster, Cartridge Actuated, XM25.' Results of performance firings at -65, 70, and 200 degrees F; six- and nine-foot drop tests; static compression-tension tests; and vibration tests indicate that the XM25 thruster met or exceeded the performance of the M20 thruster. The vibration test fixture was designed to simulate aircraft mounting. It is recommended that the X25 thruster be standardized and that it replace the M20 thruster. (Author)
