本书共分10章，讲述了飞行性能计算的原始数据，飞机的基本飞行性能，飞机的机动飞行，飞机的续航性能，起飞和着陆性能，飞机的纵向稳定性和操纵性，飞机的侧向稳定性和操纵性，基本飞行技术，特殊情况下的飞行和不对称动力飞行。
通过更加符合空气动力学的形状和一个曲线尾巴的飞机结构，这些发动机将使飞行更有效率，同时会将绝大部分的噪音传向空气上方。
With a more aerodynamic shape and framed by a curved tail plane, these engines would make for a more streamlined aircraft, as well as directing most of their noise upward.
然而，Darpa表示，在以17到22倍音速飞行的状态下，飞机还是回传了139秒的空气动力学数据。
However, the flight still managed to return 139 seconds of aerodynamic data at a velocity between 17 and 22 times the speed of sound, Darpa said.
至于模仿飞鸟飞行来改善飞机的空气动力学性能，Usherwood也不是完全有信心，但是他也并没有排除这种可能性。
As for imitating avian anatomy to amplify airplane aerodynamics, Usherwood isn't wholly convinced - but he doesn't rule out the possibility, either.
