Problems solved by technology

If the aluminum ice solid propellant cannot resist the high-pressure load in the combustion chamber, the aluminum ice solid propellant will break and break the grain, the propellant combustion surface will increase rapidly, and the combustion chamber pressure will increase rapidly. Not only the engine cannot It works normally, but it is also prone to dangers such as explosion

Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing:

[0016] combine figure 1 , the aluminum ice solid propellant compression performance testing device of the present invention includes a base 1 , a cooling pipeline 2 , a drug tank 3 , a bearing rod 5 and a stopper 6 . Before the test, coolant is passed through the cooling pipeline 2 to ensure that the base 2 and other parts are all in a low temperature state. After the raw materials such as aluminum powder and water are mixed, they are directly loaded into the medicine tank 3 to make the aluminum ice solid propellant test block 4 . During the test, open the limiter 6, take out the load-bearing rod 5, put the medicine tank 3 into the base 1, cover the limiter 6 and put the load-bearing rod 5 into the device. The whole device is put into the material testing machine, and the pressure of the material testing machine is transmitted to the surface of the aluminum ice solid prop...

Abstract

The invention provides a device for testing compression resistance of an aluminum ice solid propellant. The compression resistance testing device comprises a base (1), a chemical groove (3), a force bearing rod (5) and a limiter (6), wherein the chemical groove (3) is formed in the base (1); the limiter (6) is arranged above the base (1); the force bearing rod (5) is nested in the limiter (6) and acts on the surface of an aluminum ice solid propellant test block (4) in the chemical groove (3). When being used, the compression resistance testing device is applied to a material tester, the pressure of the material tester is transferred to the surface of the propellant test block through a mechanism, and the compression resistance of the propellant is tested. The compression resistance testing device can be applied to the field of solid propellant tests.

Description

technical field [0001] The invention relates to a device for testing the compressive performance of materials, in particular to a device for testing the compressive performance of aluminum ice solid propellants. Background technique [0002] At present, aluminum ice solid propellant has become a new propellant that has attracted much attention due to its advantages such as high calorific value and smokeless. During the working process, the solid aluminum ice propellant is always in a high-pressure state in the combustion chamber. If the solid aluminum ice propellant can resist the high-pressure load, the engine can work normally. If the aluminum ice solid propellant cannot resist the high-pressure load in the combustion chamber, the aluminum ice solid propellant will break and break the grain, the propellant combustion surface will increase rapidly, and the combustion chamber pressure will increase rapidly. Not only the engine cannot It works normally, but it is also prone ...
