Abstract:

Tests were made to obtain data which could be used to assign storage and ICC shipping classification to Air Force hypergolic igniters. The hypergolic ingiters were subjected to one cookoff test, two detonation and propagation tests, and three drop tests. These igniters are a representative of hypergolic igniters used in the SM 65 Atlas Missile. A hypergolic igniter which accidentally functions either by rupturing a diaphragm or by a puncture while in the shipping container will ignite and burn the cardboard shipping box. Igniters in contact with or adjacent to the burning igniter will not ignite. In open air, propagation will not occur between hypergolic igniters therefore blast damage will not occur. Damage, if any, will be from the heat on the O rings or igniter case. In a fire of intense heat the hypergolic igniter will burn. The igniter does not add to the fire. Cook-off time is difficult to determine since there is no visible change in the intensity of the fire. A hypergolic igniter cartridge removed from its metal shipping container and accidentally dropped from a height of more than 12 inches will cause the burst diaphragm to leak. Author
