Embodiment 1
[0044] combine figure 1 and figure 2 As shown, an experimental device suitable for solid propellant suspension combustion, including an ignition combustion device for igniting the solid propellant, a gas delivery device for delivering combustible gas and extinguishing gas, and a combustion analysis device for monitoring the solid propellant , the gas transmission device is connected to the ignition and combustion device, and the combustion analysis device is arranged on one side of the ignition and combustion device;
[0045] The ignition and combustion device includes a combustion chamber, an ignition mechanism, and a combustion channel. The ignition mechanism and the combustion channel are respectively arranged in the combustion chamber, the solid propellant is located in the combustion channel, the gas transmission device is connected to the combustion channel, and the gas transmission direction of the gas transmission device is propelled toward the solid agent; the ignitio...
Embodiment 2
[0079] An experimental device for studying the suspension combustion of solid propellants in this example differs from Example 1 in that: the aluminum-based propellant is replaced with boron-based fuel, and the atmosphere in the combustion channel is replaced with air. Connect the gas cylinder 1 filled with air with the gas flow meter 2 and the gas delivery pipe 3 .
[0080] When used, a certain mass of boron-based fuel is compressed into such figure 2 and image 3A sample is obtained in the specific shape shown, and the sample is placed in a transparent quartz tube 9, and the two ends of the ignition tungsten wire are respectively wound on a threaded copper rod, and the middle part is tensioned. Open the valve of the gas cylinder 1 and the gas flow meter 2, and adjust the flow adjustment knob 12 to suspend the sample to a certain height. Turn on the notebook computer, the high-speed camera and the fiber optic spectrometer 16, and make the high-speed camera and the fiber op...
