This paper analyses the parameter of ballistic trajectory performance of one-type seat ejection cartridge according to the technology of it,reaches its span, has established foundation for later project R&D.

This paper has established the physical and mathematics models of seat ejection cartridge,calculate with the finalized design of one seat ejection cartridge.

The feasible catapult project on high-velocity missile has been given,intcrior ballistic parameters were calculat- ed and the results have been displayed in this paper.

Through plenty of historical materials, from function of the origin of catapult, type of bow, balls of catapult and its skills, catapult martial skills are textual studied.

Design and Realization of the Control System of the Ejection Seat Training Simulator;

A Microcomputer Controlled Dynamic Property Measuring System of Pilot Ejection Simulator;

By strictly deducing and contrastly proving, a new method to realize high speed ejection is developed.

The ballistic energy and missiling velocity of bottled carbonated drinks show approximately linear relationships with gauge pressure and temperature in the bottles.
