Title Low cost air rocket warhead triggered fuze system analysis and design
Abstract The fuze is used with a certain type of air rockets, with proof, redundancy, delay arming, triggering angry functions。
To find out air rockets characteristics, access to a large number of documents, websites, collection of foreign aviation rockets information, coMParative analysis, summarized, obtained many common characteristics, based fuze design provides a design basis; in order to ensure correctness of structural design, through theoretical calculations of the weak parts of the fuze housing, thread, in order to ensure the reliability of arming, by theoretical calculation of the insurance after sitting, crawling Insurance performance analysis, the results showed that it can reliably arming; to analyze the motion of the clockwork fuze, obtained by theoretical calculation clockwork extension of time, the results show that its delay arming distance is longer than the muzzle safe distance, to protect the safety。 In order to ensure the correctness of the design size of some of the important dimensions of fuse components were calculated dimension chain。 Fuze security compliance "safety fuse design criteria" and "Environmental and fuze performance test method" requirements。
