Description

Technical Field

[0001] The invention relates to the field of separation and adjustment devices, and in particular to a separation and adjustment device which is adaptable to multiple windows, has adjustable openings and is highly precise. Background Art

[0002] Separation adjustment devices are mostly used in the fairings of missiles, rockets and other aircraft. The separation methods are mainly divided into overall fairing separation, two-petal rotation separation, two-petal horizontal push separation, multi-petal rotation separation and multi-petal horizontal push separation. The main feature of these separation methods is to first use explosive bolts and other structures to unlock the fairing and the main structure, and then complete the separation action under the action of the driving load. For example, in the overall fairing removal process, after the fairing and the carrier are unlocked, the driving force pushes the fairing forward to pull the fairing out, and then the solid small rocket arranged on the fairing is used to apply lateral thrust to deviate from the flight trajectory. Two-petal rotation separation. The fairing is first unlocked from the carrier horizontally, and then unlocked longitudinally into two half-covers. Under the action of the spring force, after each half-cover rotates around the connecting hinge to a certain extent, the fairing is completely unhooked from the hinge at the notch to achieve separation from the carrier.

[0003] In these separation structures, the separation action is often achieved by preloaded springs, small rocket engines, etc. The size of the separation port cannot be adjusted, and the degree of separation during the separation process cannot be adjusted, and only two states can be achieved: complete separation and non-separation.

The N parts are divided into the first group of parts and the second group of parts. The first group of parts is the first n parts from the inside to the outside, and the second group of parts is the n+1th part to the Nth part; The bracket is fixedly connected to the Nth part; The adjusting member is used to adjust the window between the first group of parts and the second group of parts; the adjusting end of the adjusting member acts on the first group of parts, N is a positive integer greater than 2, n∈N, n <N-1。

[0006] The beneficial effects of the present invention are: according to actual needs, N parts are divided into a first group of parts and a second group of parts by multiple fasteners, and then the first group of parts is adjusted to rise or fall a predetermined distance by an adjusting member, so as to realize a window opening structure based on the outer contour of the second group of parts, and realize a window opening lifting accuracy of a lead of P / 200. By using the installation connection of fasteners, that is, the setting of no connection relationship between the nth part and the n+1th part, N-1 different window opening structures are realized; the goals of adapting to multiple windows, adjustable opening, and high precision are realized.
