Description
Technical field
The invention belongs to aerospace engineering field, more particularly to a kind of priming system.
Background technology
Existing firer's actuator is mainly used in the weaponry in low latitude, using less in space environment.Can than
Space environment, which also takes, to work in harsh lunar surface environment, it is necessary to which the storage of actuator and use temperature range disclosure satisfy that a moon face ring
Border temperature, there need to be the performances such as mechanical, anti-lunar dust.And survey of deep space project controls the weight demands of payload tight
Lattice, it is desirable to which actuator volume is small, in light weight, reliability is high.Existing actuator is difficult to meet these requirements.
The content of the invention
The purpose of the present invention is：There is provided one kind can work in lunar surface environment, and appearance and size is small, power output
Greatly, there is firer's actuator of buffering effect.
The technical scheme is that：A kind of firer's actuator suitable for lunar surface environment condition, including：Preceding connection
Part, cylinder, piston rod, main ingredient, rear connectors, electric igniter, buffering ring；
Main ingredient is installed in plunger；
Piston rod is installed in cylinder, and front connector and rear connectors are installed in its both ends respectively；Piston rod can be in cylinder
Its axis direction of interior edge slides；
Electric igniter is arranged on cylinder, and after electric igniter detonation, ignite main ingredient, produces high temperature and high pressure gas, promotes and lives
Stopper rod moves to front connector direction；
Buffering ring is set with the outer circumference surface of piston rod, when piston rod movement to end of travel, compresses buffering ring；
Front connector, cylinder, piston rod, rear connectors use stainless steel material 1Cr17Ni2.
Beneficial effect：Profile of the present invention is small, simple in construction, reliability is high, and storage and operating temperature range are wide.Actuator
Designed using monoblock type powder charge, main ingredient is installed in the cavity on piston rod, realizes travelling charge, save barrel space.
During work, main ingredient can carry out aspect burning, have preferable adjustment effect to main ingredient burn rate and pressure.With mechanical, resist
The performances such as lunar dust, it can be used under the conditions of lunar surface environment.Actuator designs for direct-push principle, power output efficiency high,
Buffering effect is stable.By substantial amounts of ground simulation test, performance fully meets the job requirement under the conditions of lunar surface environment.
Brief description of the drawings
Fig. 1 is structure chart of the present invention when piston rod is located at initial position.
Embodiment
The present invention will now be described in detail with reference to the accompanying drawings and examples.
Referring to accompanying drawing, a kind of firer's actuator suitable for lunar surface environment condition, including：Front connector 1, cylinder 2,
Piston rod 3, main ingredient 4, rear connectors 5, electric igniter 6, buffering ring 7；
Main ingredient 4 is installed in the cavity of piston rod 3；
Piston rod 3 is installed in cylinder 2, and front connector 1 and rear connectors 5 are installed in its both ends respectively；Piston rod 3 can be
Its axis direction of the interior edge of cylinder 2 slides；
Electric igniter 6 is arranged on cylinder 2, and after electric igniter 6 detonates, ignite main ingredient 4, is produced high temperature and high pressure gas, is pushed away
Piston bar 3 moves to the direction of front connector 1；
Buffering ring 7 is set with the outer circumference surface of piston rod 3, when piston rod 3 moves to end of travel, compresses buffering ring
7；
Front connector 1, cylinder 2, piston rod 3, rear connectors 5 use stainless steel material 1Cr17Ni2.
For ensure the present invention anti-lunar dust performance, between the piston rod 3 and the cylinder 2, the rear connectors 5 with
Sealing ring is equipped between the cylinder 2, between the electric igniter 6 and the cylinder 2.
The dose of the main ingredient 4 in such scheme is increased and decreased according to the needs of load.
