F35B液压油管路出问题

Troublesome Fueldraulic Lines Removed From F-35Bs

F35B液压油管路问题

Investigators have found six additional fueldraulic lines with manufacturing defects on the Pentagon’s young F-35B fleet, which was grounded Jan. 18 after a takeoff incident at Eglin AFB, Fla.

在格林空军基地起飞事故后的1月18号，空军新组建的飞行机队F35B被发现存在6个额外的液压油管路加工缺陷，

A “quality nonconformance” in a fueldraulic tube was “the most probable cause” for the Jan. 18 operational failure, according to officials at Pratt & Whitney.

普惠官方发言人说很可能是液压油管路质量缺陷导致1月18号的飞行事故

Though the tubes are manufactured by Stratoflex, a division of Parker Aerospace, the F135 power plant for the single-engine, stealthy fighter is managed by Pratt & Whitney. The problem was most likely introduced “during the production of the fueldraulic tube,” says Matthew Bates, a spokesman for Pratt & Whitney.

普惠发言人马修贝茨说虽然液压油管路是由派克宇航Stratoflex分部加工的，但F135发动机单元的安装由普惠负责，问题很可能出在安装的液压油管路的引进上。

The six additional “non-compliant” units have been removed from the aircraft and will be replaced, says Joe Dellavedova, the Pentagon’s F-35 spokesman. The fueldraulic lines carry fuel rather than traditional hydraulic fluid to enable actuator movements for the F-35B’s short-takeoff-and-vertical-landing (stovl) vectoring exhaust system.

约翰德拉维罗说不合格的6个部件已经被替换，液压油管线使用燃油而不是传统的液压油控制离合器驱动F35B的短距起飞和垂直降落升力风扇系统。

The lines are part of the F135 power plant, which includes a unique lift fan for the stovl version. Rolls-Royce provides the lift fan.

管路是F135发动机安装的一部分，包括STOVL单元独特的升力风扇，升力风扇由罗罗公司提供

At issue were tubes that were manufactured to the design specifications but were not crimped properly, Bates says. Dellavedova says the companies are taking steps to improve quality control in building the fueldraulic lines.

贝茨说问题是管路被加工达到设计要求但没有卷曲到合适角度， 德拉维罗说公司正通过改善质量管理控制液压油线路的生产。

Inspectors will examine the lines on all of the 25 grounded Marine Corps F-35Bs.

调查组将检查海军陆战队所有25架F35B

The Marine Corps grounded all the 25 flyable F-35Bs delivered from prime contractor Lockheed Martin after a fueldraulic line was found to be “detached” when a pilot aborted a conventional takeoff in an F-35B after experiencing a failure. This has brought a halt to flight testing for the stovl fighter as well as pilot training, both of which are critical for the Marine Corps to declare initial operational capability with the aircraft.

在液压油管路出问题后，海军陆战队停飞了所有25架来自主承包商洛克希德马丁的F35B，飞行员停止了训练和战斗测试，此举影响了海军陆战队宣布的飞机初始作战计划。
