Description
Technical field
The invention belongs to weapons emitter technical fields, and in particular to a kind of eject just held for improving low-pressure chamber
Emitter.
Background technology
In MISSILE LAUNCHING, engine chamber is hyperbaric chamber, and the combustion gas that guided missile itself engine generates is sealed directly to
Launching tube so that launching tube bottom space becomes low-pressure chamber, and the indoor gas of low pressure is directly used in promotion guided missile.Combustion gas is on the one hand
Accelerate to form reaction force by Laval nozzle；Another aspect combustion gas filling low-pressure chamber space makes pressure rises to generate additionally
Thrust, this radiation pattern is known as self-eject launch.The emitter of this self-eject launch mode is simple in structure, it is empty to save
Between, loading density and fighting efficiency can be improved.But the low-pressure chamber of the emitter due to using self-eject launch mode is first
Hold smaller, guided missile overload can be caused in emission process bigger than normal, bigger than normal to launching tube inside pressure, Missile Body bottom temperature is excessively high.
Invention content
In view of this, the self-eject launch device that the object of the present invention is to provide a kind of just to hold for improving low-pressure chamber, energy
The low-pressure chamber for enough improving launching tube bottom just holds, and reduces guided missile in emission process and overloads, and reduces bullet bottom temperature and reduces launching tube
Inside pressure.
The present invention is achieved through the following technical solutions：
A kind of self-eject launch device just held for improving low-pressure chamber, including：Launching tube, guided missile, hydraulic cylinder and support
Plate；
The launching tube is internally provided with the step surface of annular；
It is machined with centre bore on the supporting plate；
Integrated connection relationship is as follows：More than two hydraulic cylinders are located inside launching tube, and cylinder body end is each attached to transmitting
On the step surface of cylinder, tailpiece of the piston rod is connected as one with the supporting plate positioned at launching tube bottom；
Guided missile is located in launching tube, and bottom contradicts on supporting plate, and the Laval nozzle of missile base passes through supporting plate
Centre bore；
When original state, the piston rod of hydraulic cylinder is in elongation state, the Laval nozzle and launching tube of missile base
Bottom connection touch；
Before launching a guided missile, drives guided missile to move upwards by hydraulic cylinder and supporting plate, make in guided missile bottom surface and launching tube
The distance of bottom surface is setpoint distance.
Further, further include launch tube closure, launch tube closure is mounted on the top of launching tube.
Further, the hydraulic cylinder is three-level cylinder.
Further, the hydraulic cylinder is two, and symmetrical centered on guided missile.
Further, one end of the launching tube is round cylinder, and the other end is square cylinder, and end is for installing where square cylinder
Hydraulic cylinder.
Further, guided missile bottom surface is the one third of launching tube length at a distance from launching tube inner bottom surface.
Advantageous effect：(1) present invention is shunk by the piston rod of hydraulic cylinder, drives supporting plate by guided missile lifting to launching tube
At the one third of length, the first appearance of the low-pressure chamber of missile base is effectively increased, the guided missile in Missile Launching Process is reduced
Overload, reduces bullet bottom temperature, reduces in emission process and is overloaded on the inside of launching tube.
(2) the configuration of the present invention is simple, compact, working environment is reliable, can under the premise of ensureing emission effciency and reliability
Effectively reduce transmitting device fabrication and maintenance cost.
(3) present invention is using in two hydraulic cylinders being diagonally distributed, when ensureing through the supporting plate lifting of missile, guided missile stress
Uniformly.

Specific implementation mode
The present invention will now be described in detail with reference to the accompanying drawings and examples.
A kind of self-eject launch device just held for improving low-pressure chamber is present embodiments provided, referring to attached drawing 1, including：
Launching tube 1, guided missile 3, hydraulic cylinder 4, supporting plate 5 and launch tube closure 6；
One end of the launching tube 1 is round cylinder, and the other end is square cylinder；
The hydraulic cylinder 4 is three-level cylinder；
The supporting plate 5 is cyclic structure；
Integrated connection relationship is as follows：Referring to attached drawing 2, be located in the square cylinder of launching tube 1 two of two hydraulic cylinders 4 are right
At angle, cylinder body end is each attached on the square cylinder of launching tube 1 and the step surface of circular cylinder intersection, tailpiece of the piston rod be located at
The supporting plate 5 of the square cylinder bottom of launching tube 1 is connected as one；
Referring to attached drawing 3, guided missile 3 is located in launching tube 1, and bottom contradicts on supporting plate 5, and the Lavalle of 3 bottom of guided missile
Jet pipe 2 passes through the centre bore of supporting plate 5；
Launch tube closure 6 is mounted on the end of the round cylinder of launching tube 1, in transportational process, preventing impurity from entering hair
In shooting cylinder 1；Launch tube closure 6 is Fragile cap, and when guided missile 3 hits launch tube closure 6, launch tube closure 6 is easily broken.
