Abstract

The invention provides a hot knife actuated split nut type compression releasing device. The device comprises two hot knives, two heat transfer sleeves, a two-petal type split nut, a rope harness, a bearing bolt, a waveform elastic washer and a spherical washer which are arranged in a space defined by a top cover and a base. The two-petal type split nut is arranged in the center of the space defined by the top cover and the base; the two heat transfer sleeves are symmetrically fixed on two petals of the two-petal type split nut; one hot knife is arranged in each heat transfer sleeve; the ropeharness is wound on an outer surface of the two-petal type split nut and the outer surface of the heat transfer sleeve; and in the locking state, the two-petal type split nut and the heat transfer sleeve are tightly bound, the spherical washer and the waveform elastic washer are arranged in an area defined by the lower portion of the two-petal type split nut and the base, and the bearing bolt sequentially penetrates through the base, the waveform elastic washer and the spherical washer and then is connected with the two-petal type split nut. The device is reliable in locking and safe in release, and has characteristics of a low impact, no pollution, low energy consumption, a high bearing capacity and miniaturization.

Description

Technical field [0001] The invention belongs to the field of aerospace technology, and particularly relates to a split nut type compression release device actuated by a hot knife. Background technique [0002] In view of the impact of shock and vibration during the launch of certain spacecraft, reliable locking devices need to be used to secure the space scientific load to ensure that the dynamic response of the system is controlled; after the spacecraft enters orbit, the scientific load should be completed according to instructions The release on orbit. The most mature pyrotechnics compression release device currently uses the energy generated by the combustion or explosion of gunpowder to achieve the release function, and its shortcomings such as non-repeatability, poor safety, large impact, and serious pollution are very prominent. For example, explosive bolts, pyrotechnic nuts, cutters, pin pullers, pyrotechnic locks, etc., often have a great impact, some even reaching 3000-...
