In this paper,various time interval initiation method are analyzed and a timing explosive initiator of high accuracy and realability for serial filling was designed and its working principle is also discussed.

Desensitive Ammunition and New Techniques of Safe Reliable Initiation;

Study on Short-duration Pulse Initiation Sensitivity of ANBDF;

Cloud initiation and detonation are dependent on delay time of ignition,initi-ating energy,detonating limit,initiating method and position.

Among all the factors affecting the performance of EFP s shaping, method of ignition is the most important one.

In this article, copper plate impression experiments of explosive charges with the same article number, the same charge density, different charge calibres and different charge heights have been carried out under the condition of two point ignition at the same time at the upside end of the charge.

It has been found that three of the reaction rate equation coefficients,namely the ignition factor I,the burning growth factor G and the coupling factor X,can each find their correspondence with the respective features of the shock initiation process.

This paper discusses the improvement of perforation technology such as pressure primer detonator,negative pressure perforation mode,secondary passage,and perforation mode optimization.
