  • LIQUID-GAS PHASE-CHANGE LAUNCHING DEVICE, AND HYPERVELOCITY PENETRATION TEST DEVICE AND METHOD
    Publication number: 20260243641
    Abstract: A liquid-gas phase-change launching device includes an initial chamber, a connecting component, a launch tube and phase-change tubes. Two ends of the initial chamber are communicated with the connecting component and the launch tube, respectively. The connecting component is provided with through holes. The phase-change tubes are communicated with the initial chamber through the through holes. The initial chamber has a cavity inside. An end of the cavity near the through holes is larger than an end of the cavity near the launch tube in caliber. The cavity includes a first sub-cavity and a second sub-cavity. A first end of the first sub-cavity is communicated with the through holes. A second end of the first sub-cavity is communicated with a first end of the second sub-cavity. A second end of the second sub-cavity is communicated with the launch tube.
