Abstract

The invention relates to a solid propellant multi-target wire dynamic combustion performance testing system and a method. The method adopts a multi-target wire combustion rate testing system; dynamic combustion performance testing can be conducted; static testing can be conducted; and two measurement modes are convenient to switch. A change relation of combustion rate-pressure and combustion rate-temperature is obtained, and a combustion rate pressure index and a combustion rate temperature sensitivity coefficient are calculated. Small-dose testing can evaluate the combustion performance of a tested propellant within a corresponding pressure temperature change range, and is very suitable for conducting rapid performance detection, quality control and the like on each batch of products in a production process of the propellant. Compared with the common combustion rate testing system, the system shortens a development production cycle of the propellant, reduces raw material consumption, reduces manual operation, and saves the cost.

Description

technical field [0001] The invention relates to a solid propellant dynamic combustion performance testing system, in particular to a solid propellant multi-target line dynamic combustion performance testing system and method. Background technique [0002] In the development and production of solid propellants, as well as the initial stage of solid engine development, technical parameters such as propellant burning rate, burning rate pressure index, and burning rate temperature sensitivity coefficient directly affect the internal ballistic performance, flight speed and stability of the rocket engine. Work. Existing methods for measuring static burning rate characteristics mainly use nitrogen target line method or underwater acoustic emission method. These two methods are to test the burning rate of the solid propellant sample rod under the condition of constant pressure and temperature. It is necessary to test the static burning rate at several pressure points to obtain the ...
