In this paper,a kind of metal material is presented,it makes the cost of the flyer impact initiation detonation experiment much lower than before and provide the availability for people to study the impact initiation mechanism of explosive.

The fragment impact initiation of the charge covered with a thin plate was researched.

Based on an analysis of the shock initiation theory of explosives,the annular structure booster pellet and the annular conical structure booster pellet were designed.

In order to meet the requirement of insensitive ammunition,the concave-spherical booster pellet and hemispherical booster pellet are designed based on shock initiation theory,and the initiation capacity of the new booster pellet structure is compared with that of the regular cylinder booster pellet.

Based on the one-dimensional energy criterion of explosives shock initiation,considering the shock propagation of projectile impacting covered explosives,the relation formula of threshold velocity is obtained as Vw≈0.

The general principles and application background in energy usage, aerospace and aeronautics of pulse detonation technology are presented in this paper.

Based on the research of using natural energy, a system is established which is named the pulse detonation power generation system of combustible matter.

Experimental investigation on the mixing chamber in pulse detonation chamber;

Pulse detonation engine has received much attention of late because of its several advantages compared to existent engines.

Using kerosene as fuel and air as oxidizer,two-phase detonation experiments were successfully conducted in two pulse detonation engine models with the diameters of 30 mm and 50 mm respectively.
