The basic thrust is to provide a high-volume transport for use when reliability is not required or is maintained in a different manner.
如果可靠性不是必需的或者可靠性是以不同方式进行维护，那么基本要求就是为使用提供一个高容量的传输。

The F-35B Lightning II short takeoff/vertical landing (STOVL) variant has demonstrated during testing that it produces excess vertical thrust - more than required to carry out its missions.
Particularly with Taper Roller Bearings sufficient support of bearing rings by the adjacent parts is required due to the generated internal thrust force components.
