Embodiment 1

[0042] see figure 1: The present application provides a missile fragile front cover, comprising: a front cover body 100 provided with a weakened groove 110, and a mooring mechanism 200 for constraining splashing of the front cover body; the weakened groove 110 extends to the front The radial and / or latitudinal arrangement of the cover body 100 divides the front cover body 100 into a plurality of regions 120 to be broken by the weakened groove; the mooring mechanism 200 is provided with fixed ends 201 at both ends Rope 210; one end of the mooring mechanism 200 is used for fixed connection with the cylinder wall B of the missile launching cylinder;

[0043] Preferably, in one of the preferred technical solutions of this embodiment, the weakening groove is arranged along the radial direction of the front cover body, and the end of the mooring mechanism fixedly connected with the region to be ruptured is located at the region to be ruptured. On the axis of symmetry of the zone, a...

Embodiment 2

[0047] Such as figure 2 As shown, the fragile front cover of the missile is composed of a front cover body 100, an upper flange ring 300, a lower flange ring 400, a sealing ring 500 and a mooring mechanism 200, wherein the front cover body 100 and the upper flange ring 300, the lower The flange ring 400 is connected by bolts, and the mooring mechanism 200 is connected with the front cover body 100 and the upper flange ring 300 .

[0048] Specifically, in the above structure, the lower flange ring is used for fixed and sealed connection with the barrel edge of the missile launching tube; The hole position is matched with the through hole, and is fixedly connected with the missile launching tube through the fastening and pressing between the upper flange ring and the lower flange ring.

[0049] Preferably, in one of the preferred technical solutions of this embodiment, the fragile front cover structure of the missile includes: a body layer 101, a reinforcement layer 102, a shi...

Embodiment 3

[0059] This embodiment provides a method for preparing a missile fragile front cover, the method comprising the following steps:

[0060] The upper flange ring and the lower flange ring whose shape is compatible with the launch port of the missile launching tube are manufactured by mechanical processing technology; bolt holes are respectively processed on the upper flange ring and the lower flange ring;

[0061] The reinforcement layer is manufactured by compression molding injection molding process;

[0062] The front cover body is made on the upper end surface of the reinforcement layer by foaming process; the edge of the front cover body is provided with a cover edge required for press-fit sealing connection with the flange ring; the radial and radial directions of the front cover body / or Weakening grooves are provided in the weft direction;

[0063] Spraying or brushing the heat-resistant paint after grinding the upper end surface of the front cover body;

[0064] Maki...

Abstract

The invention is used to improve the technical problem of poor safety of the existing fragile front cover of the missile, and provides a fragile front cover of the missile and a preparation method thereof; wherein the structure includes: a front cover body provided with a weakening groove, and a mooring mechanism The weakening groove is set along the radial and / or latitudinal direction of the front cover body, and the front cover body is divided into multiple regions to be broken by the weakening groove; the mooring mechanism is a rope with fixed ends at both ends. The method comprises the following steps: making an upper flange ring and a lower flange ring; manufacturing a reinforcement layer and a front cover body; setting weakening grooves in the radial direction and / or latitudinal direction of the front cover body; grinding the upper end surface of the front cover body After spraying or brushing heat-resistant paint; making a gasket whose shape matches the shape of the pressing surface between the upper flange ring and the lower flange ring; making the seal between the lower flange ring and the outer wall of the missile launch tube launch port sealing strip. The invention can simultaneously meet the use requirements of both bursting and bursting, and it is not easy to cause fragments to splash when the front cover is broken.

Description

technical field [0001] The invention relates to the technical field of missile storage and transportation, in particular to a missile fragile front cover and a preparation method thereof. Background technique [0002] Box-type thermal launch is a commonly used tactical missile launch method. When the missile is launched, in order to reduce the complexity of the equipment and simplify the launch process, the front and rear covers of the launch box are often made of fragile covers. The power source of the back cover of the box cover comes from the closed and suppressed pressure generated when the missile is ignited, and the front cover is broken into several pieces under the action of the missile warhead or the initial shock wave, and is thrown around to open the channel for the missile launch. The separation method of the front cover has always been a research difficulty in this field at the beginning of the design. The choice of whether to use the missile warhead to burst or...
