"After successfully completing the static test programme on the F-35 (known as AG-1) we have now returned the aircraft back to Lockheed Martin, Fort Worth.
The static test programme broke all records for the speed of testing having applied more than 150 different loading configurations in just over nine months.
Having proven the strength of the aircraft is now beginning the 4500 mile journey back to the US after almost three and a half years in the structural test facility at Brough.
Static testing the F-35 means that the aircraft has been ‘flown’ to its limits with loads applied to it replicating the effect of high gravitational forces far beyond any conditions likely to be flown in actual flight. This is done with the airframe nesting in a multi-million pound rig kitted out with over 4000 strain gauges, 170 actuators and over 50 miles of wiring at our Brough site in Yorkshire. Brough is home to a world leading facility for putting aircraft through their paces to ensure they are strong enough and resilient enough to perform in the harshest environments in the world.
Tim Bramhall runs the F-35 structural test programme at Brough said “We certainly don’t give the aircraft an easy ride here. We push it to its limits so that we can be confident that each of the 3000+ aircraft that have been ordered will perform safely and effectively. The real challenge is keeping aircraft weight at a minimum whilst maintaining the strength of the plane within certain specified limits”
With this set of tests complete Tim added “We still have another F-35 CTOL airframe in the facility undergoing fatigue testing along with the remaining horizontal and vertical tails from the Carrier variant. Work on those continues on schedule and are shining examples of the long term future the structural test facility has ahead.”
That's all folk!

英文里面好像没有什么结构强度远超预期水平的话
不过是说静力实验中承受的力量远大于实际飞行中可能受到的。

俺还以为早就都试验完了……好像一直有童鞋在吐槽某国飞机都快交付了，静力试验还在进行？
静力早就完成了吧，这应该是AG-1从BAE运回到洛马沃斯堡而已。

“Contractor and government officials announced on 19 September 2011 that static structural testing of the F-35 Lightning II had been successfully completed. Static structural testing is used to verify the structural integrity of the airframe. In static testing, external loads designed to simulate the pressures of full envelope flight conditions are applied to hundreds of points on the airframe using a system of load pads, hydraulic actuators, air pressurization mechanisms, and reaction channels. In the final phase of static testing, the airframe was pushed to 150 percent of requirements to verify that there was no structural failure. Engineering teams at Lockheed Martin, BAE Systems, Northrop Grumman and the F-35 Joint Program Office conducted the tests over the past two years.”
2011年9月19日就完成了，成功经受住了150%的应力。

也一直搞到去年9月？过程够长。

一般静力试验受得力要比实际飞行大很多，基本是67%相当于最大的情况

F-35的静力机体生产的比较靠后，以F-35B为例，已经生产了2架试飞型后，用于静力试验的BG-1才被生产出来。所以总的测试时间并不是特别长。更何况F-35有三个型号，需要分别生产静力机体、分别测试。
修改：之前记错了，查了资料之后发现BG-1应该是第三架B型机体，排在BF-1、BF-2之后。

偶还以为现在才完成呢，还想吐槽咋静力木完成就敢交货滴体制问题呢......不带这么糊弄人滴啊......不过话说如果去年9月才完成静力现在就敢交货那也算是十分牛叉滴吧？会不会有体制问题泥？

有些试验是要花时间的。

要开始考虑减重了吧。

E文中没有这句话。
现在的f35重量是达标的，如果出现实际强度远超过预计强度，岂不是意味着现在的设计能继续做超出性能要求的减重。这是不可能的。

F35的重量管理依然是个问题，不过这个是指一些非主要受力部位但却非常重要的部分，例如B型的升力风扇进气、两侧喷气口挡板等部分，主要是前期认为基于F22的架构设计并简化，整体上应该没有大问题，而且很多设计上并没有做实物测试就直接用计算机设计结果造了，试飞后才发现强度不够，需要补强，重量就这么一点一点上去了。后来骡马与罗罗绞尽脑汁减重，甚至把B型升力风扇空心程度进一度加大到令人发指的程度。现在看F35整体上的应力强度应该是过关了，但局部来说可能还需要进一步想办法优化，尤其是可能要做改动的C型和麻烦不断的B型。

我记得是在《军事评论》上看到的，B型前风扇在冷风状态下能达到如此高的功率，已经很了得了。
