Background technology
Electromotor operation is typically necessary lighter to realize lighting a fire.Conventional lighter includes at present：Pyrotechnic igniter,
Plasma igniter and hot-shot ignition device etc..Pyrotechnic igniter forms high temperature gas flow, but the lighter using gunpowder explosion
Can not reuse, it is difficult to realize electromotor repeat light a fire.Plasma igniter is lighted a fire using plasma jet, but should
Lighter bulky, and need powerful power supply to produce plasma, significantly increase system burden.
Hot-shot ignition device is burnt using fuel and oxidant, produces high temperature gas flow to realize lighting a fire.Heat common at present
Jet initiation device has hydrogen/oxygen lighter, ethanol/oxygen lighter, kerosene/oxygen lighter, nitrous oxide/hydrogen point
Firearm etc., but above-mentioned lighter is generally used for Test System for Rocket Engine Test field, is applied to scramjet engine igniting also face
Face some problems：(1) it is not kerosene more than the fuel of above-mentioned lighter, needs to increase a single lighter fuel supply system
System；(2) although the fuel of some lighters be kerosene, but oxidant is oxygen or liquid oxygen, rather than safer air,
Increased the danger of system.
If a kind of lighter can be designed, using kerosene and air as fuel and oxidant, high-energy after burning, is discharged
High-temperature fuel gas, the kerosene for recycling combustion gas ignition engine burning indoor and air mixture, then lighter and electromotor
A set of fuel system can be shared, so as to cost and the complexity of pilot system is greatly reduced.The difficult point of this lighter
It is how to design kerosene nozzle and lighter combustor, just can ensure that kerosene is effectively atomized, can be sufficiently mixed with air, and
Kerosene flame being capable of stable existence.The open report of such kerosene air igniter there is no at present.
