Many sample continuous ignition's laser ignition experimental apparatus

The utility model discloses a many sample continuous ignition's laser ignition experimental apparatus, including lens gland, laser lens, combustion chamber casing, intake pipe, lower box lid, lower box, wire barrel, lower box bottom plate, step motor, synchronous pulley, hold -in range, step -by -step axle, sample tray, baffle, blast pipe. Fix the solid propellant sample in putting the thing groove earlier during the use. It is later right the utility model discloses carry out the gas tightness and detect, confirm the utility model discloses open the laser instrument after the gas tightness is good and light first root solid propellant sample, later give the pulse of step motor some for next solid propellant sample just in time is located the laser lens under, ignites once more, and the step is accomplished until whole ignition of sample more than repeating. The utility model discloses it is easy and simple to handle, can realize the many continuous laser of sample ignition experiments in an airtight combustion chamber, and the quantity of sample can be according to the size of a dimension adjustment of combustion chamber.
