  • Device operating by means of pyrotechnic charges for releasing joints subject to load
    Patent number: 4493241
    Abstract: A device is described which operates with pyrotechnic charges to release nts under load effected between a plurality of constructional components and including bolts acted on by transverse forces. An example of such a device is for the separation of the rotor blades of a helicopter in order to be able to eject the crew upwards from the helicopter by an escape system without danger on failure of the helicopter to fly. The bolts of the joint are connected to a housing having a cylindrical bore of which the axis lies substantially in the direction of the resultant of the forces necessary to release the joint by extracting the bolts. On one of the constructional components there is a piston which supports itself on said component and engages in a cylindrical bore of the housing. The pyrotechnic charge is situated in the space between the end of the piston and the base of the cylinder bore. An ignition device for the pyrotechnic charge is provided on the housing.
