Design and performance exploration of an igniter for a UAV rocket booster
This article introduces the design and selection of structure,ignition components,main charge agent,and ignition agent of an igniter.A semiconductor bridge ignition component,and two compatible ignition agents are used to make the ignition components.The inner layer agent of the ignition component has good ignition reliability,the outer layer agent has high energy density and the reaction is fast.Therefore,the comprehensive performance of the ignition components is improved.The ignition output pressure index of the igniter is mainly studied.The experimental results show that in a 590 mL chamber,the ignition output pressure is not less than 5.5 MPa,and the action time is not more than 100 ms.And other properies of the igniter are verified too.The results indicate that this igniter has superior electrical performance and high ignition reliability,meets the operation requirements of the UAV rocket boosters,and has good application prospects.
