    摘要:

    系统研究了一种铝合金面板/ 聚甲基丙烯酰亚胺(PMI)泡沫夹层结构低温贮箱共底的结构设计、
    关键制造技术及结构性能ꎬ该贮箱共底成功通过了气密试验、低温打压及隔热性能等试验考核ꎬ单底内压0.54
    MPaꎬ低温打压煤油箱压力0.40 MPaꎬ氧箱压力0.47 MPaꎬ共底面板不皱损、不失稳ꎬ煤油温度不低于17℃ꎮ 研
    制的夹层共底能够满足大温差(约210℃)、轻质化和发射前无需抽真空隔热等的使用需求ꎬ为我国新一代运载
    火箭成功研制奠定了技术基础。

    Abstract:

    As an ideal layout scheme for launch vehicleꎬ co ̄bulkhead tank can improve the slenderness ratio of
    launch vehicleꎬ reduce structure weight and increase structure efficiency and carrying capacity of launch vehicle. This
    paper systematically studied the structure designꎬ key manufacturing technology and structural property of the alumi ̄
    num alloy panel/ polymethacrylimide (PMI) foam ̄sandwiched cryogenic tank co ̄bulkheadꎬ which successfully passed
    the air ̄tight testꎬ the low ̄temperature pressure test and the thermal insulation test. The single ̄bottom inner pressure
    was 0.54 MPaꎬ and the low ̄temperature pressure in coal oil tank and liquid oxygen tank were 0.40 MPa and 0.47
    MPa respectively. The co ̄bulkhead was not wrinkling or collapse after the testsꎬ and the temperature of the coal oil
    was higher than 17℃.The sandwiched co ̄bulkhead meets the using requirements of large temperature differenceꎬ light
    weight and no vacuum pumping for thermal insulation before launchingꎬ laying technological foundation for successful
    development of the new ̄generation launch vehicles.
