In the event of an aircraft crash, the impact resistance performance of the fuel tank is essential to maximize the survivability of the crew. Damage caused by excessive load on the fuel cell and interference between the fuel cell and the surrounding structure is a main cause in case of an aircraft accident. The fuel system of fuel tank for aircraft should be designed to prevent fuel cell damage by minimizing interference with the fuel cell on collision impact while performing fuel transfer and refueling functions. In this study, we developed a fuel system for an external auxiliary fuel tank that meets the impact resistance performance of MIL-DTL-27422D. Phase II certification tests, which demonstrate the fuel cell's own performance, proved that the fuel system did not damage the fuel cell.

在飞机坠毁的情况下，燃油箱的抗冲击性能对于最大化机组人员的生存能力至关重要。在飞机事故中，由燃料电池上的超负荷以及燃料电池与周围结构之间的干扰引起的损坏是主要原因。飞机燃油箱的燃油系统应设计成在执行燃油传输和加油功能时，通过将碰撞时对燃油电池的干扰降到最低来防止燃油电池损坏。在这项研究中，我们开发了一种用于外部辅助油箱的燃油系统，该系统符合MIL-DTL-27422D的耐冲击性能。证明燃料电池自身性能的II期认证测试证明，燃料系统未损坏燃料电池。
