Embodiment 1

[0020] A solid propellant flame splitting device, comprising a directional support 1, a bracket 2, a quartz glass plate 3, a solid propellant support 5, a base 6, a rotating shaft support 7, a connecting block 8 and an ignition plate 9. The support 2 is L-shaped, and the vertical bar of the support 2 is rotatably connected with the rotating shaft support 7, so that the L-shaped support 2 can move up and down. The rotating shaft support 7 is welded on the base 6, the bottom of the cross bar of the support 2 has a first groove along the length direction, the quartz glass plate 3 is arranged in the first groove of the support 2, and the two ends are fixed by screws for easy disassembly and replacement. Set along the length of the bar. The solid propellant support 5 is threaded on the base 6 and is located below the center of the bottom edge of the quartz glass plate 3 . The fire pressing plate 9 is provided with 502 glue, and is fixedly connected with the bottom side of the quar...

Abstract

The invention discloses a solid propellant flame splitting device, which comprises a directional support, a bracket, a quartz glass plate, a solid propellant support, a base, a rotating shaft support, a connection block and a fire pressing plate. When in use, the support is lifted up, the solid propellant is set on the solid propellant support, and ignited. Press the bracket down so that the bracket falls on the grooves on the top of the two directional supports. At this time, the quartz glass plate and the pressing plate just fall on the flame of the solid propellant, and the pressing plate presses the flame halfway. At this time, the quartz glass The plate separates the flame from the middle, and the movement process of the metal aluminum particles in the unpressed flame on the other side of the flame is observed from the side with the fire pressing plate using a schlieren instrument. The invention has a simple structure and is easy to operate. Both the quartz glass plate and the fire pressing plate are light-transmitting and high-temperature-resistant glass, which is convenient for the schlieren instrument to observe the movement state of metal aluminum particles in the flame.

Description

technical field [0001] The invention belongs to flame separation equipment, in particular to a solid propellant flame separation device. Background technique [0002] Modern solid propellants mostly contain aluminum particles in order to increase the specific impulse. Metal aluminum particles will change the combustion characteristics of solid propellants. The application of aluminum powder as a high-energy metal fuel in solid propellants and explosives has attracted widespread attention from scholars at home and abroad. . Understanding the ignition and combustion properties of aluminum powder is of great significance for revealing the combustion mechanism of solid propellants and its application in solid propellants, and can also provide the necessary basic data for the simulation of solid propellant combustion. [0003] Chinese scholar An Ting, in the article "Thermite's Effect on the Laser Ignition Characteristics of Double-base Solid Propellants", observed the state of ...
