Abstract:

A high-altitude igniter for use with the M6A1C Honest John rocket has been developed by the Materials Laboratory now designated Propulsion Laboratories, Ordnance Missile Laboratories, for the Army Ballistic Missile Agency. The igniter, which is essentially a modification of the standard M35A1 igniter, is capable of igniting the Honest John rocket motor at an altitude of 35,000 feet and a temperature of 0 F. Approximately 38 igniter firings were made in a dummy motor during developmental testing at various pressure-simulated altitudes and at temperatures from 0 F to -40 F. Delay times for the final design ranged from 10 to 30 milliseconds at an altitude of 35,000 feet and at a temperature of 0 F. Two igniters conditioned for 6 hours at 0 F and 40 F were tested in a full-scale motor at a simulated altitude of 30,000 feet. These firings were satisfactory in all respects ignition delays were 23 and 11 milliseconds, respectively. Author
