Abstract

The invention relates to an ignition control device of a combustion-driven all gas-phase iodine laser combustion chamber and a control method. The device is provided with a data acquisition controller; the control voltage output by the controller is connected with a spark device through a voltage regulator and a drive circuit; then the spark device is connected to a spark plug through a conductive wire; and a control program is stored in the data acquisition controller. The method comprises the steps of presetting the amount of the gas-flow rate; introducing an oxidant into the combustion chamber according to the preset flow rate; starting an ignition switch, and igniting a fire maker; introducing fuel into the combustion chamber according to the preset flow rate; judging whether the ignition is successful according to the changes of the temperature and the pressure as well as the illumination condition of the combustion chamber; if the ignition is successful, adding other experimental gases; stopping the ignition switch, and stopping igniting the fire maker; stopping introducing the gas into each pipeline; and finishing the experiment. The invention has the advantages of simple structure, low cost, convenient operation, high efficiency, safety and good ignition effect, and ensures that the gas ignition implementation of the combustion chamber is simple in an ordinary laboratory.

Description

technical field [0001] The invention relates to an ignition control technology, in particular to a remote ignition control device and a control method for burning and driving a full-gas-phase iodine laser combustion chamber. Background technique [0002] All gas-phase iodine laser (AGIL, all gas-phases iodine laser) is a new type of iodine laser based on NCl(a)-I energy transfer. The volume efficiency and weight efficiency brought about by the phase reaction are limited to increase the volume efficiency and weight efficiency and the use of this gas-liquid reaction in some gravity-free environments. AGIL's technical route is as follows: [0003] F+DCl->DF+Cl [0004] Cl+HN 3 ->HCl+N 3 [0005] Cl+N 3 ->NCl(a)+N 2 [0006] NCl(a)+I->NCl(X)+I * [0007] I * +hv(1315nm)->I+2hv(1315nm) [0008] From the 1990s to the present, AGIL has gone through the research stages of conception, pulsed light output, continuous flow gain test of the discharge scheme, c...
