美国波音公司目前正在设计制造新一代的无人驾驶飞机,与其他大多数无人机不同的是,波音无人机将不再采用以机翼作为燃料储备舱的设计思想,因为这种设计思想限制了机翼空气动力学方面的性能。由于机翼不再需要承担双重任务,因此,可以将它们制作得比其他无人机的机翼更长、更薄、更有效。飞机将使用真空瓶存储液态氢,在引擎启动时,真空瓶会释放液态氢为飞机引擎提供燃料。 U.S. Boeing is currently designing and manufacturing a new generation of unmanned aircraft. Unlike most drones, Boeing UAVs will no longer use the design concept of a wing as a fuel storage tank because of this design concept. The wing aerodynamic performance is limited. Since wings no longer have to take on double tasks, they can be made longer, thinner, and more efficient than the wings of other drones. The aircraft will use a vacuum bottle to store liquid hydrogen. When the engine is started, the vacuum bottle will release liquid hydrogen to fuel the aircraft engine.
