The propeller of the plane is out of order, and is under repair. 这架飞机的螺旋桨出了点问题,正在维修。
It took 13 hours on a propeller plane. 一架螺旋桨飞机整整飞了13个小时。
They will eventually be permanently attached to the propeller shrouds and hull, and they will also house the stern plane hinge mechanism. 他们最终会被永久地附加到螺旋桨整流罩和船体,他们也将内务严峻平面铰链机制。
Suddenly, according to an account in The Washington Post, the crowd saw a little propeller plane buzzing along with a sleek fighter jet flying circles around it. 突然,据华盛顿邮报的话说,观众们看见一架小螺旋桨飞机嗡嗡飞来,身旁盘旋着一架光滑抢眼的喷气式战斗机。
The disadvantages would be engine cooling plus an ejecction system or propeller jettison would have to be designed for the pilot to safely exit the plane in case of an emergency. 劣势在于引擎冷却的问题,还有喷气系统和螺旋桨的抛弃要设计得符合紧急情况下飞行员逃生的安全性。
