Problems solved by technology

Since the work of the explosive bolt or cutter is to achieve material fracture within a few hundred microseconds, the pre-tightening force of the tape and the strain energy of the docking frame are also released instantly, and the separation impact of the tape-type separation device is too large. The safety of electronic instruments and equipment on payloads and launch vehicles poses hidden dangers
At the same time, since the separation pyrotechnic elements such as explosive bolts or cutters cannot be reused after working once, the unlocking and separation of the tape cannot be pre-detected on the ground, which is not conducive to improving the separation reliability

Abstract

The invention discloses a non-firework slow releasing device for connection and unlocking of a wire type separating device. The non-firework slow releasing device comprises a left rotating screw rod,a right rotating screw rod, a shell, a slowly opening device and an unlocking device, wherein the slowly opening device is connected with the unlocking device; the slowly opening device and the unlocking device are arranged inside the shell; the unlocking device can be used for making the slowly opening device rotate; the left rotating screw rod is connected with the slowly opening device throughthe shell; and the right rotating screw rod is connected with the slowly opening device through the shell. The non-firework slow releasing device disclosed by the invention improves the safety of thedevice, has repeated test capability and also reduces the separation impact.

Description

technical field [0001] The invention belongs to the technical field of launch vehicle payload separation structure, and in particular relates to a non-pyrotechnic slow-release device used for connecting and unlocking a line separation device. Background technique [0002] There are two main types of payload separation devices for launch vehicles: point-type separation devices and tape separation devices. Due to the advantages of good connection stiffness, high reliability, and strong carrying capacity, the tape separation device has become the mainstream payload separation device for launch vehicles at home and abroad. The most widely used separation device. [0003] The tape separation device is mainly composed of two or more tapes, multiple V-shaped clamping blocks, column shafts and separation pyrotechnic elements and other parts. The column shaft is installed at both ends of the steel belt, and a V-shaped block is installed on the inner side of the steel belt. After th...
