Abstract

The invention discloses a redundant multi-unlocking driving separation and release device which comprises a split nut, a radial limiting device, a lining frame, a locking device and an integrated unlocking device, the split nut clamps and limits separation of a separation bolt, and the radial limiting device limits opening of the split nut in the radial direction. The locking device is used for connecting and locking the radial limiting device and the lining frame, and the integrated unlocking device is used for releasing the locking state of the locking device so that the radial limiting device can move in the axial direction, the contact position of the split nut and the radial limiting device can be changed, and therefore the split nut can release radial limitation to achieve the separation purpose. Unlocking and releasing of the separation bolt are mainly converted into a mechanical control mode of simple axial movement of a mechanical structure, separation of large equipment driven by a small mechanical combined structure can be achieved, generated impact force is small, the mechanical structure layout is simple, the action mode is simple and direct, the efficient unlocking process is achieved, and the mechanical structure is simple in structure. And various unlocking operation mechanisms can be integrated.

Description

technical field [0001] The invention relates to the technical field of rocket separation, in particular to a redundant multiple unlocking drive separation and release device. Background technique [0002] Spacecraft separation and release technology is an important research and application content in the aerospace field, and it is a key link that affects the success or failure of aerospace missions. As a key product to realize connection and unlocking, the separation device needs to focus on the working reliability and environmental adaptability within the flight profile. Generally speaking, according to the classification of the structure, the separation device can be divided into point separation, line separation, etc.; according to the classification of the working principle, it can be divided into pyrotechnic separation device, non-pyrotechnic separation device and so on. Due to its non-polluting and environment-friendly characteristics, non-pyrotechnical separation dev...
