Study on Mechanism of Burn Rate Enhancement of Solid Propellant with Plasma and Modeling of Multidimensional Multiphase Flow;

The principle and method for testing the atomized field of liquid propellants with a pulsed laser holography were introduced.

Based on a suspended droplet apparatus and a high speed camera, the ignition and combustion properties of a HAN based liquid propellant LP1846 droplet have been investigated under rich in water vapor hot ambience.

The droplet distributing properties in atomization field of HAN based liquid propellant have been experimentally investigated by use of laser holographic system.

In the regenerative liquid propellant gun,the coupling oscillation of the fluid sys-tem in the reservoir including free vibration and forced vibration may be formed.

Aimed at nonsteady spray combustion flow problems of regenerative liquid propellant gun (RLPG)in process of interior ballistic,mathematical model was established,and numerical method was derived.

To study the method of controlling the combustion stability in bulk-loaded liquid propellant gun,a 2-D model of gas jet expansion process in the stepped-wall chamber was developed.

The control technology of combustion stability is one of key technology of regenerative liquid propellant guns.

In regenerative liquid propellant guns(RLPG),the breakup and atomization affect the control of RLPG interior ballistics.

The results are important for the development of liquid propellant gun
