Reuters) - The Pentagon program chief for the F-35 warplane slammed the main contractors on the program, Lockheed Martin (LMT.N) and Pratt & Whitney, on Wednesday, accusing them of trying to "squeeze every nickel" out of the U.S. government and failing to see the long-term benefits of the project.
U.S. Lieutenant General Christopher Bogdan made the comments during a visit to Australia, where he has sought to convince lawmakers and generals to stick to a plan to buy 100 of the jets, an exercise complicated by the second grounding of the plane this year and looming U.S. defense cuts.
Pratt & Whitney, a unit of United Technologies Corp (UTX.N), is sole supplier of engines to the $396 billion F-35, or Joint Strike Fighter. Lockheed Martin provides the body of the radar-evading jet, the most expensive combat aircraft in history.
"What I see Lockheed Martin and Pratt & Whitney doing today is behaving as if they are getting ready to sell me the very last F-35 and the very last engine and are trying to squeeze every nickel out of that last F-35 and that last engine," Bogdan told reporters at the Australian International Airshow in southern Victoria state.
"I want them both to start behaving like they want to be around for 40 years," he added. "I want them to take on some of the risk of this program, I want them to invest in cost reductions, I want them to do the things that will build a better relationship. I'm not getting all that love yet."
Lockheed Martin said it was "singularly focused" on properly executing its contracts to develop, produce and sustain the new warplane, and insisted it was on track to finish development by 2017.
"We do this in partnership with Lieutenant General Bogdan and the entire JSF Program Office and strive daily to drive costs out of the program," said spokesman Michael Rein.
He said the company had reduced costs by 50 percent since the first production airplanes were built, and remained confident that the sixth and seventh production deals, currently under negotiation, would result in further savings.
Pratt & Whitney had no immediate comment.
Bogdan caused a stir shortly after joining the F-35 program last August when he described the relationship between the government and Lockheed Martin as the worst he'd ever seen. There had been little improvement since then, he said.
"Are they getting better? A little bit," he said. "Are they getting better at a rate I want to see them getting better? No, not yet."
If the project stays on track, Pratt & Whitney will eventually provide 4,000 engines and Lockheed Martin 3,000 planes.
The Pentagon plans to buy 2,443 of the warplanes in the coming decades, although many analysts believe U.S. budget constraints and deficits will reduce that number.
Australia, a close American ally, is considering doubling its fleet of 24 Boeing Co (BA.N) F/A-18 Super Hornets amid delays and setbacks in the F-35 project. That means Canberra could buy far fewer F-35s than initially planned.
LEAKS
Bogdan was also critical of what he suggested were leaks from Pratt & Whitney's camp about the engine issue, which led the Pentagon to suspend F-35 flights last Friday.
Two sources told Reuters that Pratt & Whitney is 99 percent sure the fan blade problem that grounded the jets was not caused by high-cycle fatigue, which could force a costly design change, and the aircraft could be flying again within the week.
"Until all those tests are done and I see the results, I don't know what's going on," Bogdan said. "However ... my gut would tell me it's on the spectrum of the minor side - 99 percent is bold, flying next week is bold."
Bogdan also gave the example of taking six months to close a deal with Pratt & Whitney for engines on its fifth bloc of jets, shortly after General Electric Co (GE.N) had been dropped as a second supplier of engines for the program, leaving Pratt & Whitney as sole supplier for the next 40 years.
"Now, you would think a company like Pratt & Whitney that was just given the greatest Christmas gift you could ever, ever get for a company would act a little differently," Bogdan said.
Bogdan is flying back to the United States this weekend, just in time to hear about the future of U.S. military budgets, which are slated to be cut by nearly $500 billion over the next decade, an amount which could double unless Congress acts in the next week to avert spending reductions known as "sequestration".
Bogdan said he was confident the F-35 program would remain on track and on budget if he was given the discretion to deal with any cuts.
The risk is that money is cut from the $6 billion set aside for the development program by the end of October next year.
"I need every penny of that $6 billion to get over the finish line," Bogdan said. "If they take money out of development something's going to have to give. I'm either going to have to push the program out or I'm going to have to shed capability."
Budget cuts aside, Bogdan said he was confident of bringing the cost of each plane down to around $90 million by 2013, compared to around $120 million now.
Budget cuts have already forced Italy to scale back its F-35 orders, and Turkey has delayed its purchases by two years. Orders from Japan and Israel have buoyed the project, and additional Israeli orders are expected in 2013.
Lockheed is building three different models of the F-35 for the U.S. military and eight countries that helped pay for its development: Britain, Canada, Italy, Turkey, Denmark, the Netherlands, Australia and Norway.

这句我和楼主理解不同。
这句的意思是，普惠很肯定这个不是高频疲劳造成的，飞机可以在一周内恢复飞行。高频疲劳则需要昂贵的重设计。

很明显是楼主理解错了。
这条新闻的意思是如果是因为疲劳导致裂缝那么则需要高昂的重新设计，但是现在可以确认裂缝不是因为疲劳造成的，所以不需要重新设计。

原文意思 基本上确定不是需要重新设计的高疲劳所致，一周内恢复飞行
丰胸来的花冻机搞地蛋疼！！！
好的最好普惠在f22上也找到同样问题
这篇报道是关于五角大楼JSF项目组主管对F-35发动机叶片裂纹导致停飞事件和部分客户可能削减订单问题的答复。
普惠说99%的可能性，问题不是叶片的疲劳所致，相信一周后可复飞。但这货坚持说担心那1%，认为基于99%没问题的判断而复飞是很大胆（莽撞）的行为。这货吐槽了很多普惠和骡马，说这俩坑爹货态度不端正，就像是在卖最后一架飞机和最后一台发动机一样，没有要供货40年的伙伴应有的长久眼光。特别是普惠刚刚被给了圣诞礼物：排除了GE，使普惠成为F35项目唯一发动机供货商。这货还透漏：骡马自从首批飞机生产以来，飞机成本以下降了50%，他真在就第六、七批次生产砍价。这货还承诺，2013飞机的成本削减目标是从现在的1.2亿刀降到9000万刀。总之，要压供应商降价，要说服客户项目会按计划实现，别削减订单。
比我们的八股好多了，基本都是人话。

今年球电就跟双风一个价了？
有人信么
有人信么
喜闻乐见，这是标题党，改一改吧
这个叫啥来着？定语从句？
天涯这翻译，刚好把意思说反了，是钓鱼帖吧
发动机什么部位的裂痕?
已经有好几个上钩了。昨天就有人兴冲冲地来隔壁发帖高兴地宣布费电的发动机完了，结果原来是这么回事。。
楼主理解反了！

9000万，比“双风”还便宜；
欧洲的独立战斗机工业，到此为止了。

普惠又犯老毛病了，当年也是一门心思钻钱眼，逼得USAF扶持起F110，看来F136还有复活的机会吧...

停飞结束了：http://www.politico.com/story/20 ... rounding-88277.html
Lockheed Martin's F-35 Lightning II is returning to flight after its grounding last week over a crack discovered in an engine blade aboard an Air Force-model jet, POLITICO has learned.
The decision is effective immediately, said Joe DellaVedova, a spokesman for the Defense Department’s F-35 Joint Program Office. Pentagon officials were planning to issue a statement on the decision later Thursday evening.
恢复飞行，该决定立即生效。停飞了一周零2天。

F-35其实正在渐入佳境。
简单说两句：
1、还在试飞中的新发机型，存在疲劳寿命问题的可能性有，不过机率不大，报道中所说排除寿命原因是有可能的。
2、如果不是疲劳寿命原因，那么很可能是叶片设计有问题，重新设计恐怕在所难免。

已经报道了，基本上不会需要太大的设计改变，可能只是由于偶然的一次叶片过热，或者制造时留下的缺陷

Pratt & Whitney is 99% sure the fan blade problem that grounded the Pentagon’s 51 new F-35 fighter jets was not caused by high-cycle fatigue, which could force a costly design change, according to two sources familiar with an investigation by the enginemaker.
such as high heat exposure or a manufacturing problem, that would be easier to solve, the sources said.
简单说两句：
1、还在试飞中的新发机型，存在疲劳寿命问题的可能性有，不过机率不大，报道中所说排除寿命 ...

呵呵，如果是疲劳寿命，反倒好解决。
排除了寿命原因，那么可能的原因就不好说了。
过热肯定是设计问题。
制造缺陷，呵呵，美鬼加工能力不错，可能性很小。

波格丹？ 呵呵 一开始还以为是毛子那个试飞员呢

“疲劳寿命，反倒好解决”？
看看人家的原文，疲劳问题会“could force a costly design change”，会导致昂贵的设计改变；
其他问题是“be easier to solve”，是更容易解决的。
如果是外来异物损坏，根本就不需要重新设计，呵呵。
“制造缺陷，美鬼加工能力不错，可能性很小” 前几天F35B的尾喷管液压管问题，就是制造缺陷导致的，你难道忘了么，呵呵。

晕。你学下统计好不好?
如果是疲劳问题，才700小时，离要求差十万八千里。当然要改设计。
独立的制造问题就无所谓。越生产，自动化程度越高，精度越高，生产问题的可能性越小。
人家都已经复飞了，你还呵呵。太酸了。

疲劳寿命问题，更换材料，或者改进原有的加工工艺，可以解决。 何况F135用的也不是美鬼最好的料。
所谓的解决费用昂贵，只是夸大而已。
开发过程中，制造问题往往更多是由于设计引起，设计成熟了才突出加工问题。 以美鬼的加工能力，加工因素的可能性很小。

楼主的英语宾语从句部分需要补课。

最终原因也没说就复飞？看来也不会是材料原因罗
再断裂几次，问题就清晰了。 不要大惊小怪，开发过程中这样的代价是必须的，既然这么急着要复飞，呵呵

你根本不懂统计学吧?
任何制造，手工越多，统计上的误差就越大。这个和设计无关。
生产线不是造第一台时就整好的。你可以去看每次的合同，除了生产合同，还有很多准备合同。这些准备合同就是慢慢把生产线堆出来。
出了事故，主要查的就是这个是单一现象还是普遍现象。在飞的几十架都查了，没有发现其它发动机有裂纹。在这个数据量下，可以肯定说是单一现象(这个也是需要用统计来算的)。
人家都复飞了，你还在这里自言自语。非常建议你学一下统计。

不得不佩服汉语的博大精深。。。
2楼 翻译准确。。 楼主 没看清楚 which指代的内容。。
总之比起当年的空中喷零件的太行是牛逼了不少。只是我们没有记者拿着放大镜到处追问而已
语出惊人，英语不说重要至少很有用
路透社报道，故障是叶片长时间暴露在热环境中引起的：“prolonged exposure to high levels of heat and other operational stressors”。
“The tests showed that the crack resulted from the "unique operating environment" in flight tests -- many of which tested the engine's powerful after burners -- rather than a high-cycle fatigue crack, which would have required a design change.
Bates said the engine in question had operated at high temperatures for more than four times longer than a typical F-35 flight, which led to a separation of the "grain boundary" of this particular blade.”
这架F-35A是一架试飞用机，由于其独一无二的试飞安排，使得其在试飞中打开加力的时间，比普通飞行状态高出了4倍以上。低压涡轮叶片长时间暴露在加力燃烧的热辐射环境中，导致了“晶界”出现缺口。
