A sleeve type fork ear support rod structure for a booster

Abstract

The invention relates to a sleeve type fork lug supporting rod structure for a booster, and belongs to the technical field of guided missile structures. The sleeve type fork lug supporting rod structure comprises a supporting rod and a stop thread insert, a threaded section is arranged on the supporting rod and connected with a missile body, a hexagonal boss is arranged on the lower portion of the threaded section, a cylindrical boss is arranged on the lower portion of the hexagonal boss and used for limiting the upper end face of the stop thread insert, the lower end face of the supporting rod is a plane and contacts with a convex lug plane of the booster, and a left stop surface and a right stop surface are arranged at the lower end of the stop thread insert. Left and right swing of the booster is limited by the stop thread insert when the booster acts, the gap between the booster and a convex lug is automatically adjusted around a rotating axis, and the booster can successfully fall off under the action of the gravity of the booster and aerodynamic force when thrust of the booster vanishes. The sleeve type fork lug supporting rod structure solves the problem that a past booster cannot fall off as the convex lug of the booster and the supporting rod are jammed in the past.

Description

technical field [0001] The invention relates to a sleeve type fork lug support rod structure for a booster, belonging to the technical field of missile structures. Background technique [0002] Generally, a single booster is used to launch a booster missile. The booster is generally fixed on the rear and lower part of the missile by means of suspension, so that the thrust line can pass through the center of gravity of the missile, and the booster is suspended on the missile body through a joint. In order to adjust the thrust arm and limit the left and right swing, a set of fixed support rods are installed on the body, and the thrust arm of the booster is adjusted by adjusting the height of the support rod from the axis of the body. In order to ensure that the booster does not move left , Right swing, and at the same time, there is no transition constraint, and one of the support rods is designed as a fork ear structure to limit the booster.

AI Technical Summary

Problems solved by technology

[0003] In a flight test of a certain model, when the thrust of the booster is large and the weight is light, the fork-shaped support rod rotates around the axis to produce elastic deformation, which affects the normal separation of the booster and the missile body
