METHOD FOR ABSORPTION OF ENERGY OF IMPACT PULSE EMERGING AT ACTUATION OF PYROMECHANISM, AND PYROMECHANISM

摘要

A method for absorption of energy of impact pulse emerging at actuation of pyromechanism, and the pyromechanism relate to the field of rocket-space and aviation engineering. According to the method one splits the front of blast wave of powder gases formed at operation of pyrocharge of the pyromechanism, to separate gas jets, kinetic energy of blast wave transferred to the movable mass of the rod and to the body of pyromechanism is absorbed by cells of absorber with smooth retardation of impact force of movable parts of pyromechanism with a crusher. The pyro-mechanism has a body, a working chamber in the body, a movable rod, a chamber with gas ducts in the movable rod, a stopper and pyrocharge. Additionally it is equipped with multi-channel splitter as perforated plate installed in the chamber of the movable rod on springy anti-impact base, like rubber washer, a blast wave absorber, this is arranged as twisted impact-absorbing fiber and installed in the working chamber of the body of pyromechanism and a crusher arranged with varying cross-section and with perforated wall and installed inside the pyromechanism between the movable rod and the fixed body with support by movable rod and the stopper of the pyromechanism.
