飞机燃油系统是飞机不可或缺的系统,燃油量占据了飞机近50%的重量和机翼翼盒80%多的空间,而且现代飞机愈加依赖燃油质量特性来调整重心,机电系统必须基于实时的燃油量状态和系统状态的精确获取,因此现代先进飞机复杂燃油箱中的燃油量测量和燃油质量特性计算成为燃油系统最为关注的基本问题.本文给出了以STL模型为基础的飞机燃油箱燃油量、燃油质量特性计算的主要实现方法和优点.%The fuel system is the indispensable system of aircraft, fuel quantity is nearly 50% of the aircraft weight and over 80% of the wing space. And more aircrafts depend on fuel gravity to adjust center of aircraft gravity, accurate fuel measurement is a base for electromechanical integration. So the basic item is how to accurately measure fuel quantity and how to calculate fuel gravity in modern aircraft complex tank. The main method and advantage that calculate fuel quantity and gravity are preseted based on STL format file.
