在航空学诞生后近50年来,英国工程师首先提出对飞机的装置作重要改变:用电动系统来代替所有的液压和气压系统。打开乘客室门,放下起落架以及大量其他作业都将由电磁装置来完成。电动设备更为可靠,更为容易修理,重量也更轻。因此,电动飞机所消耗的燃料也就更少。因此,它还能避免由 Nearly 50 years after the birth of aeronautics, British engineers first proposed a major change to the aircraft’s installation: replacing all hydraulic and pneumatic systems with electric systems. Opening the passenger compartment door, lowering the landing gear, and a host of other operations will be done by the electromagnet. Electric equipment is more reliable, easier to repair, and lighter in weight. Therefore, electric aircraft also consume less fuel. So it can be avoided too
