the customers more often than not tell the fact than the suppliers.
So... are we seeing PLAAF pilots complaining about the engines? I don't recall seeing that... so by your logic, the engine is good to go? Or do we actually need to see that engine in service with foreign nations before saying that the engine is good? Note that US, Russia and I am most certain that some of the European nations' do not export some of their engines too... and are these engine actually no good, or not mature... since no real facts are given?
i m saying let customers, preferably foreigners, to tell us the facts ( whether good or bad)
us,russia,europe have had mature engine tech for a long time than china who started her 1st high thrust engine.
so generally speaking one may safely assume they r "alright."

WS-15 Thread
Hey people. After having WS-10 thread, I know very soon we will need one for WS-15, and so here it is. I hope this thread can be used for WS-15 related stories and developments.
And start posting!

打好每一场型号攻坚战
——记中航工业成发技术中心压涡室

长寿命设计是当前航空发动机技术发展的一项关键技术，而盘、轴、叶片等关键零部件则是上述关键技术中的核心。成发技术中心压涡室承担着公司此类核心技术的开发研究，他们的创新能力决定着发动机研制的进展乃至企业的技术水平。2012年，压涡室全员以“咬定青山不放松”的精神，迎难而上，先后解决了某型涡轮轴抗低周疲劳设计和考核验证，某涡轮盘的循环疲劳试验设计和考核等数十项科研攻坚任务，为型号研制奠定了坚实的基础。 “我喜欢干项目！”这是压涡室副主任吴国炜常说的一句话。正是由于喜欢，自2007年从北京航空航天大学毕业进厂后，始终全身心扑在项目上。“拼了！”成了吴国炜的“口头禅”，正是这股“拼劲儿”，短短5年时间，他从一名普通的设计人员，迅速成长为公司型号研制不可缺少的中坚力量。“2012年的低压涡轮轴试验载荷设计与其他设计不同，从头到尾都由我们自主设计”，他自豪之情喜上眉梢。转子结构复杂，轴、载荷计算难度极大，设计前要综合考虑方案，既不能低于飞行环境要求，又不能使载荷过于严酷。吴国炜争取有效时间查阅大量飞机、发动机技术资料，对发动机外部、内部载荷以及特殊工况载荷的循环分析，确定设计循环载荷谱等，解决了低压涡轮轴试验载荷设计中遇到的一项项关键瓶颈问题，通过外部专家评审、指导，最终完成了轴试验工作，为型号鉴定、定寿工作奠定了扎实的基础。工作中，吴国炜总是有条不紊地带领团队开展攻关，年仅28岁的他，根根白发与他年龄极不相符。在型号攻关的决战阶段，加班成了正常的上班，工作到凌晨成了家常便饭，目的是“把一个个阻碍研制进度的技术关键消灭在苗头阶段。”
2012年，某型机长试进入关键阶段，压气机、涡轮部分长试装机零组件技术状态审查、问题归零及总结成为压涡室的工作重点，刘燕萍负责装机零组件技术状态的逐一清查。该型号发动机零件种类多、数量大，作为压涡室唯一的女同志，她巾帼不让须眉，查阅大量资料，计算数据，现场核准，编制零组件状态管理树形目录。对试车发动机的单机零组件技术状态进行收集整理，为顺利完成长试技术状态总结打下了基础。一年来，加班加点成了刘燕萍的家常便饭。每晚打个电话，问问儿子作业做得怎么样？有没有好好吃饭？叮嘱孩子要听爷爷奶奶的话。晚上10点过了，她办公室的灯依然亮着。
娄涛2012年最难忘的工作莫过于某型机高压涡轮2级盘低循环疲劳试验。从过完年开始，娄涛就着手定试验件、装配、工装加工，形成整个试验件组件。该试验件要求完成6750个循环，并作阶段性探伤。前期试验还算顺利，但循环到2000个左右时，试验盘出现裂纹！这可急坏了压涡室的所有人，因为试验结果直接影响到长试进度。“就是不眠不休也要保证试验工作顺利开展！”娄涛开始排查原材料、设计、工艺、质量等一切与此相关的数据，通过对裂纹尺寸、表面粗糙度、理化分析，终于找出了问题根源。他将所有设计参数、试验设备、试验过程记录细细复查一遍，并与负责该试验方案的研究所对接，重新计算试验方案。“十一”长假一开始，他便扎进了试验室重新试验，这一扎就是4个月，终于在2013年1月30日完成试验。 这个团队的成员平均年龄不满26岁，却担当起为科研试车保驾护航的重任。“中国梦”在他们心里投影成“航空梦”，而“航空梦”又被一个个不眠不休的攻关夜和一点点被解开的项目难题所组成，用汗水浇铸中国心，用实干托起中国梦，他们用青春和智慧鲜明地诠释了自己心中的“中国梦”和“航空梦”。
