请教通用、罗罗、普惠联合研制F136叶片技术取得进展水准 ...

防卫新闻消息：
两家发动机巨头联合研制第三级低压陶瓷基矩阵结构复合材料涡轮叶片， 可降低重量，加大抗高温能力和提高推力。这项工作旨在研究所谓发动机“热端”使用的轻质高强度符合材料部件。
估计可以为135、136发动机的制造和维护节省30亿美元。
该技术也可以用在通用的700发动机上。136发动机面临被国会枪毙的可能。因为国会相信这是多余的，费钱的勾当。

不解1：难道低压压气机不是冷端吗？在下小白，请教高僧了。
不解2：陶瓷基矩阵结构符合材料涡轮叶片技术难度有高家庄高吗？TG需要追多远？

谢谢解惑。

Team Aims to Decrease JSF Engine Costs by Billions

Published: 16 Jun 2010 10:11  Print  |    EmailThe makers of the F-35 Joint Strike Fighter (JSF) engine and a proposed alternative engine have teamed with the Pentagon to develop new heat resistant engine components projected to save billions of dollars in the purchase and maintenance of the engines, according to a Pentagon report to Congress.

"The General Electric Rolls-Royce Fighter Engine Team developed and implemented third-stage, low pressure turbine vanes made from ceramic matrix composites" to give the airplanes more thrust, range and fuel efficiency due to their lighter weight and increased heat tolerances, according to the Pentagon's Annual Industrial Capabilities Report to Congress, which was published in May.

The composite vanes were developed as part of a Pentagon project to develop lightweight, high-strength composite parts that can withstand the incredibly high temperatures found in the "hot section" of a jet engine, according to the report. Other members of the team to develop such parts included the U.S. Air Force, Navy and Pratt & Whitney.

The performance increases expected to be brought about by the project are "projected to decrease production and maintenance costs by over $3 billion" for the JSF's Pratt & Whitney-built engine, known as the F135, as well as its controversial alternate engine made by GE and Rolls Royce, known as the F136.

These savings are also expected to apply to GE's T700 turbine engine used on military helicopters such as the UH-60 Black Hawk, AH-64 Apache and AH-1W Super Cobra, according to the document.防卫新闻消息：
