Abstract

1336789 Igniters for parachute suspended flares THIOKOL CHEMICAL CORP 9 Aug 1971 [10 Sept 1970] 37341/71 Heading F3A An igniter for an aircraft-launched, parachutesuspended flare comprises a lanyard 13 for transmitting the pull from the parachute to a lever 19 which is arranged to retract and then release a striker 25 for movement against a primer 31, the primer serving to ignite a pelletized boron potassium nitrate composition 33 which in turn ignites a wafer 35 formed of a dispersion of ammonium perchlorate in a matrix of acrylobutadiene polymer. The latter ignites the flare composition 45 and is protected against inadvertent ignition by dropping, with the aid of a piece of foamed polystyrene 37. A shear pin 23 retains the lever 19 in its inactive position.
