飞机放燃油工具的新式设计

Redesign of Fuel Sump Drain Tool

飞机放燃油工具的旧式设计使得机务人员不能清洁、方便地完成放出飞机燃油沉淀并进行油样收集工作。分析旧式采用开放式设计的放燃油工具所存在的缺陷，介绍一种新式采用封闭式设计的放燃油工具，并将新式设计在航空机务工作中使用验证。结果表明：新式设计可以解决旧式设计所存在的缺陷。

The crew can not clean and release fuel deposits of aircraft and collect fuel samples by currently open- designed fuel sump drain tool. The defects of currently open-designed fuel sump drain tool are analyzed and a new type of flaring fuel tool with closed design is introduced. The new one can solve existing problems in the old one and has already been verified in aviation maintenance.
