EVALUATION OF IGNITER RAM-JET ENGINE, M114
Abstract
ONE HUNDRED AND ONE IGNITERS WERE FUNCTIONED IMMEDIATELY AFTER REMOVAL FROM THE SEALED CANS. All 85 igniters from Lot PA-67-3 and 15 igniters from Lot PA-67-1, functioned with a small delay. The other igniter from Lot PA-67-1 failed to ignite the illuminant. Another group of igniters were conditioned to 120 F and 95% humidity from 6 to 72 hours. All igniters functioned after 24 hours of conditioning. At the end of 48 hours of conditioning 3 igniters from Lot PA-19-1 functioned, all other igniters failed. Another group of 18 igniters from Lot PA-67-2 and 6 igniters from Lot PA-19-1 were coated with an epoxy resin and placed in phenolic engine cases before subjecting them to 120 F and 95% humidity. Six igniters from Lot PA-67-2 were functioned after 48 hours and 96 hours; the remaining igniters functioned normally after 192 hours of conditioning. The epoxy coated igniters are recommended for use where there are high humidity conditions. (Author)
