我们只是还不知道怎么在航行的空气动力学方面,对飞机实现需要的控制。
We do not yet know how to achieve the desired control during the aerodynamic phase of flight.
制造更符合空气动力学的飞机,并用更有效的方式来运营飞机——例如减少空中交通控制而产生的延误,这些方法可以为这些节省做出大约三分之二的贡献。
Building more aerodynamic aircraft and operating them more efficiently (by reducing air-traffic-control delays, for instance) could produce about two-thirds of those savings.
因为它们的两副翅膀叠在一起,在空气动力学的理论中,这意味着它们对自己身体缺乏控制力。
Because their two sets of wings effectively flap as one, that in theory gives them little control over the aerodynamic forces on their body.
