Abstract
The present invention provides a kind of pneumatic transmitting barrel structure, and initial velocity is provided when taking off for scout missile.The pneumatic transmitting barrel structure, including cylinder, piston, restriction orifice, tether, gas generator, inner bottom plating, controller, Outer Bottom Plating, adjusting screw, wherein gas generator has two, and controller is used for the time interval for controlling two gas generators to start.The beneficial effects of the invention are as follows, gas generator, which is connected to after enabling signal, can sequentially activate under the action of controller, discharge gases at high pressure, gases at high pressure promote piston and scout missile to accelerate together through restriction orifice, during piston motion to cylinder edge, tether is tensioned, and piston separates under the pulling force of tether with scout missile, while quickly reduction of speed and is rested in cylinder, ensure that gases at high pressure are not excessive, it can be achieved that noiseless, unglazed launching effect；In addition, adjusting the axial location of inner bottom plating by adjusting screw, change emission cavity internal volume, and then change the effect of emission rate；By varying the aperture of restriction orifice, gas rate of release is can control, and then changes the effect that size is overloaded in transmitting.
Description
Technical field
The present invention is a kind of pneumatic launching tube mechanism, initial velocity is provided when can take off for scout missile, suitable for using
Catapult-assisted take-off formula scout missile and scout missile technical field.
Background technology
Scout missile is that one kind can carry out " flight of cruising ", the new concept ammunition of " standby target of attack " above target area,
With scouting, hit integrated ability.This new attack mode is just paid close attention to, US and Russia once proposition be subject to many countries
Research one after another it has been carried out with Fa Deng states of Germany and Britain.The pneumatic launching tube mechanism research conditions of scout missile are as follows：U.S.'s switchblade hair
Shooting cylinder cylinder shares three layers, is followed successively by Kev drawing from inside to outside, lightweight mother metal, Kev are drawn；The gas of its gas generator release
For high-temperature fuel gas, and push directly on piston motion；Piston underlying space size is unadjustable.
This method causes cylinder processed complex；Meanwhile after gas generator starts, piston lower portion pressure can raise rapidly,
Cause to accelerate overload peak value larger so that scout missile body structure is easily damaged；In addition, overloaded in accelerator and go out a speed
It is unadjustable, the relative motion performance requirement that different band load shell is taken off can not be adapted to.
The content of the invention
The object of the present invention is to provide a kind of pneumatic transmitting barrel structure, initial velocity is provided when taking off for scout missile.This
Invention requires solve the problems, such as it is that cylinder reduces difficulty of processing on the premise of lightweight is kept；Scout missile is in accelerator at the same time
Middle overload is as small as possible, and overloads and go out a speed and adjust, to adapt to the mission need of different band load shell.
The technical scheme is that cylinder uses pp plastics outsourcing Kev pull-up structures.Gas generator has two, according to
Filling medicament amount is divided into small one and large one, and the order and time interval of two generators startups are controlled using controller, is specially first
Start small gas generator, treat that piston and body have accelerated a distance, cylinder pressure peak value to restart atmospheric hair later
Raw device.
In the present invention, current limiting orifice plate between piston and gas generator, the orifice plate has not only acted as the work to piston limit
With, while the aperture of orifice plate adjusts, that is, promotes the gas flow of piston motion to adjust；The position of inner bottom plating also may be used at the same time
Adjust, i.e., the size of cavity volume can be adjusted under piston.
The advantages and positive effects of the present invention are：(1) cylinder reduces difficulty of processing on the premise of small quality is ensured
And cost.The difference of (2) two gas generator explosive payloads and coordinate uniqueness Starting mode solve early takeoff by
Cavity volume is small under piston, and gas quick release causes pressure rise excessive velocities, and then overloads the problem of excessive, avoid patrol it is winged
Body structural damage in accelerator.(3) can by the axial location of the pore size and inner bottom plating that adjust restriction orifice
Adjust the overload in accelerator and go out the size of a speed, and then be suitable for different band load shell or different model bullet
The mission need of body.
Brief description of the drawings
Attached drawing 1 is the launching tube structure chart of the present invention.
Embodiment
Below in conjunction with the accompanying drawings the present invention is further illustrated with example.
As shown in Figure 1, a kind of pneumatic launching tube mechanism, including cylinder 1, piston 2, restriction orifice 3, tether 4, gas occur
Device 5, inner bottom plating 6, controller 7, Outer Bottom Plating 8, adjusting screw 9.
Before transmitting, the restriction orifice 3 in suitable aperture is first installed, inner bottom plating 6 is adjusted with the thread fitting nut of adjusting screw 9
Axial location and fixation, adjust corresponding 4 length of tether and its both ends be separately fixed on 2 bottom of piston and inner bottom plating 6,
Enabling signal is provided to controller 7, two gas generators 5 sequentially activate and discharge gases at high pressure, and gases at high pressure are through metering hole
Plate 3 promotes piston 2 and scout missile to accelerate together, and during piston motion to 1 edge of cylinder, tether 4 is tensioned, and piston 2 is being
Separated under the pulling force of rope with scout missile.
