查询词典 mach speed

His team was asked to design a Mach 2 2.5 aircraft, which was then, and probably still is, a nontrivial task-especially when the objective is to create a "cheap" lightweight aircraft. Consider that the force required to overcome drag quadruples when doubling the speed, and what impact that has on aircraft weight.

要知道当飞行速度由单音速变为双音速时，空气阻力会增加至原来的四倍，考虑到因此所需要的动力，及其对机身重量的影响，满足这样的需求，即使是在今天也绝非易事。
