Made use of the principle of high frequency heating up and computerized realtime data acquiring techenique, a set of system is found to heat up and to realtime measure the temperature of the target on the light gas gun .

One stage light gas gun as a loading device, laser velocity interferometer and manganin piezoresistance measurement as means of data collection are used in the experiment.

By tracing the gas moving regularity after the projectile with Largrange approach and adopting Von Neumann Richtmyer Scheme, this paper simulates numerically the 1 D interior ballistic process of one stage light gas gun with shoulder of chamber and finite length chamber under the change of initial temperature and relative charge mass.

Using light-gas gun loading and VISAR(Laser velocity Intervene instrument) technology,three HR-2 steel samples with different thickness were struck at 500 m/s velocity by a flyer.

This method can be used to calculate the perfor mance of light-gas guns.

In this paper,studied the appliance of the piezoresistive method in light-gas gun experiments through measuring the shock Hugonoit line of one material,gai.

A numerical method for simulating launch process of two-stage light-gas gun is established.

Based on establishing a mathematical model for launching process of two-stage light-gas gun and computing it numerically, the theoretical computation is accomplished.

Two-stage light-gas gun is a firing system which can obtain high velocity of projectile by high temperature and low molecular weight medium expanding to force projectile moving.

The launching technique to enhance the projectile velocities of a two-stage light gas gun was studied in this paper.

Use of two-stage light gas guns is one of the techniques extensively used to achieve hypervelocity projectiles.

1 km/s by using the two-stage light gas gun to penetrate a semj-infinite-thick steel target with incident angle θ=0°～85°.

Impact-damage experiments on limestone specimens were carried out on one-stage light-gas gun.
