| Abstract: |
| To solve the problems of bolt through-hole penetration and direct contact between the bolt and head with the oil in the sealing-off structure of airdrop rubber fuel drum，the design of the sealing-off in the top and bottom of the rubber fuel drum was improved，so as to effectively avoid safely hazards such as the penetration destruction of the overall structure of the fuel drum，“thread climbing”leakage and “core suction” penetration inside the drum body material.The airdrop test showed that the rubber fuel drum with improved sealing-off could meet the requirements of the airdrop under extremely complex conditions. |
