Technical field
The present invention relates to a kind of igniter, and in particular to a kind of laser ignition equipment.
Background technology
The propellant that rocket engine is used has two kinds of forms, and one kind is liquid, and another kind is solid matter.Burning
Agent and oxidant are all then to be referred to as liquid fuel motor in the engine of liquid form, or are liquid-propellant rocket engine, two
Person is then referred to as solid propellant engine or solid propellant rocket in solid state.If in two kinds of fuel, one
Kind it is solid, one kind is liquid, then referred to as solid-liquid rocket engine or directly claim the rocket engine of its material title.Such as,
Hydrogen-oxygen rocket.Because the energy that the energy ratio liquid oxidizer that solid-state incendiary agent is produced sends is high, so, the fire of development
Arrow engine is mostly solid-liquid rocket engine, and two kinds of fuel meet burning, forms high temperature and high pressure gas, and gas is from spout spray
Go out, produce huge thrust and carrier rocket has been served space.Existing rocket fuel generally uses stove silk or electrode discharge
Arc light goes to light, effect on driving birds is not good.
The content of the invention
For not enough present on prior art, the present invention seeks to be to provide a kind of laser ignition equipment, structure letter
Single, easy to use and reliable, igniting is simple, practical, can real-time detection light needed for time and burning data.
To achieve these goals, the present invention is to realize by the following technical solutions：Laser ignition equipment, including swash
Optical generator, reflective mirror, the first focus lamp, form mirror and generation room is lighted, laser generator exit is provided with reflective mirror, instead
Light microscopic lower section is disposed with the first focus lamp, form mirror and lights generation room, and form mirror is arranged on and lights generation ceiling portion,
Described generation room of lighting includes cavity, workbench, inductor probe, camera monitoring window, viewing window and ventilation mouth, in cavity
Portion is provided with workbench, and the material lighted in need is placed on workbench, and workbench side is provided with inductor probe, inductor
Probe is connected with the visual detector of containment portion, and the position that cavity both sides outer wall is flushed with workbench is provided with camera monitoring window
Mouth, viewing window, viewing window lower section are provided with ventilation mouth.
Preferably, described ventilation mouth is vacuum orifice, described viewing window is drain hole.
Preferably, described ventilation mouthful is externally connected to valve.
Preferably, the igniting flow of described laser ignition equipment：Put material → vacuumize → laser ignition → measuring point
The data such as pressure, the composition produced the time required to combustion and after burning.
Beneficial effects of the present invention：Simple structure, easy to use and reliable, igniting is simple, practical, being capable of real-time detection
Time and burning data needed for lighting.
Brief description of the drawings
Describe the present invention in detail with reference to the accompanying drawings and detailed description；
Fig. 1 is structural representation of the invention.
Specific embodiment
For technological means, creation characteristic, reached purpose and effect for making present invention realization are easy to understand, with reference to
Specific embodiment, is expanded on further the present invention.
Reference picture 1, this specific embodiment uses following technical scheme：Laser ignition equipment, including laser generator 1,
Reflective mirror 2, the first focus lamp 3, form mirror 4 and light generation room 5, the exit of laser generator 1 is provided with reflective mirror 2, reflective
The lower section of mirror 2 is disposed with the first focus lamp 3, form mirror 4 and lights generation room 5, and form mirror 4 is arranged on and lights generation room 5
Top, described generation room 5 of lighting includes cavity 51, workbench 52, inductor probe 53, camera monitoring window 54, viewing window
55 are internally provided with workbench 52, the material lighted in need, workbench 52 are placed on workbench 52 with ventilation mouth 56, cavity 51
Side is provided with inductor probe 53, and inductor probe 53 is connected with the visual detector 6 outside cavity 51, outside the both sides of cavity 51
The position that wall is flushed with workbench 52 is provided with camera monitoring window 54, viewing window 55, and the lower section of viewing window 55 is provided with ventilation mouth
56。
It is worth noting that, described ventilation mouthful 56 i.e. vacuum orifice, described viewing window 55 is drain hole.
It is worth noting that, described ventilation mouthful 56 is externally connected to valve.
Additionally, the igniting flow of described laser ignition equipment：Put material → vacuumize → laser ignition → measuring point combustion institute
The data such as pressure, the composition produced after taking time and burning.
After this specific embodiment laser generator occurs laser, lead to there is room top, laser by reflector alignment
After crossing the first focus lamp and form mirror, spot diameter is 4mm or so, and fuel can be quickly lighted well, and hot spot is too small and is difficult
In lighting.If vacuumizing, fuel will be with combustion adjuvant, generally potassium chlorate, potassium permanganate etc., and interior occurs can not also take out very
Sky, or specific gas are placed into after vacuumizing, it is for deliberation.The material for needing to light is put on workbench, it is highly supervised with shooting
Survey window and drain hole quite, have valve outside ventilation mouth, can adjust, vacuumize late gate closing, having surveyed after each item data can
Open again.Inductor is popped one's head in data transfers such as pressure, temperature to external message handler, carries out data analysis.
