The engineering test of the XM159/C rocket launcher was conducted at Aberdeen Proving Ground, Maryland from December 1967 through 16 Jul 1968. Environmental tests, including simulated helicopter vibration, rain, temperature-humidity, salt spray, sand and dust, and high and low temperature, were conducted. The primary objective of the test was to evaluate the launcher for suitability for use on the UH-1 series helicopter. The test results revealed deficiencies in the electrical firing-circuit design, the ability of the launcher to withstand the aircraft vibration test, and the gas impingement principle of operation of the rocket-motor detent. Shortcomings included excessive corrosion on and about the firing contact, the failure of the firing contacts to reliably return to the forward position after firing, inadequate quality control during manfacturing, and the failure to meet the accuracy requirements. The XM159/C rocket launcher, as designed, is not considered suitable for the intended use. It is recommended that the launcher be improved to correct the deficiencies and shortcoming noted in this report. (Author)
