某机点火成功,为党的生日献礼



2016年6月30日下午5点34分,黎阳试车台内爆发出阵阵掌声,公司某新机成功实现加力点火,整个过程经历部分加力、小加力、全加力三个状态,在加力点火整个过程中发动机工作稳定,标志着该新型发动机在研制道路上获得了一座重要里程碑,也为党的95岁生日献上了一份宝贵的礼物。

为完成某机点火试验,6月26日以来,试车小组在组长陆凤魁的带领下,始终以“铁军”的精神品质扎根车台一线。他们每天加班至第二天凌晨,无怨无悔,高效完成各项工作。值得一提的是该试车小组5名成员里有4人是团员青年,他们工作经验不足,但是每天以满腔的激情、强烈的责任心完成工作,晚上加班至深夜,他们不叫苦不叫累,工作现场总能看到他们乐观的笑容。同时,他们喜欢学习,追求上进,工作之余,他们积极向设计所人员学习与发动机相关的各项知识,为完成试验任务做好知识储备。
试车小组如此,电气仪表工作人员也一样。他们和试车人员一起,每天加班加点,为发动机试验做好电气控制、仪表测量的各项保障工作。电气检查测量电阻时,密密麻麻的针脚看得他们眼睛发花,发动机每次试车前电气工作人员需要测量上百个电阻,排查与发动机控制相关的故障时都离不开他们,一个小小的故障需要花费他们大量的时间和精力检查试车台架和发动机电气线路情况。
发动机点火成功,让人振奋,同时也鼓舞我们继续努力奋斗,勇往直前,为国家武器装备事业贡献更大的力量。


七月一日,这是一个特殊的日子,配装黎阳公司某型发动机的飞机轰鸣声震醒了北方静寂的大地,成功实现首飞。
上午,9时53分,配装黎阳某发动机的飞机昂首冲向天空,按照预定航路完成爬行、飞行等任务,10时01分成功着陆,整个飞行过程中发动机工作7分33秒,参数正常,工作稳定。“成功了!”“成功了!”机场响起了一片欢呼声。
在建党95周年之际,黎阳人以实际行动向祖国交了一份厚礼,践行“动力强军 科技报国”的使命,以迎难而上的决心,坚定不移的信心,持之以恒的耐心,为航空发动机事业冲锋在前,贡献智慧和力量。
作为该型机总承制单位,公司充分发挥了“厂所结合”优势,在各承制单位的大力配合和全体参研人员的共同努力下,攻坚克难,亮剑图强,通力协作,出色完成任务并成功实现首飞,标志着该型新机研制工作取得阶段性胜利,是中推涡扇新机研制中又一个非常重要的里程碑!

A new milestone for China's turbofan engine, then I cannot think any other than the mighty WS-15.

is there a mnimum duration to test the engine before declared ok? whats the TTW ratio of the new ws-13? thanks

More than 400 WS-10 series domestic engines have been installed on J-11B,D, J-16 since the end of (2015), no accident occurred so far
日前,中航工业发布2015年社会责任报告,其中“太行”发动机批量装备部队,中航工业已具备自主研发第三代大推力发动机的能力格外引人瞩目,曾几何时, 军用航空大推力发动机和CPU一样是中国的心病,也是一些网络舆论用来贬低中国工业水准的最佳武器。但从今往后,能够用于贬低中国工业水平和自主技术实力 的例子又少了一项,中国成为继美国和俄罗斯后,第三个批量装备国产大推力军用航空发动机的国家。就在中国取得这一成就的背后,有谁知道涡扇10所经历的艰 辛。

“太行”发动机已批量装备部队

截至2015年底,410厂已向海军、空军交付涡扇10发动机不少于400余台,被用于J11B、J11D、J16等机型,装备了不少于5个航空团。虽然经历了磕磕碰碰,但截至目前,没有一架搭载涡扇10发动机的战机因发动机故障坠毁。


在 今年年初,中国航空报公布了涡扇10发动机改进型号由中航工业动力所研制成功的消息。改进版本的涡扇10发动机将加力推力提升到14-14.5吨,实现在 综合性能(最大加力推力、寿命、推重比)方面,涡扇10及其改进型号足以和俄罗斯的AL31F及其改进型AL31F-99M1/M2等发动机相媲美。

改 进版涡扇10发动机另一项重大改进就是航空发动机的全权限数字电子控制系统。航空发动机的全权限数字电子控制系统(英文简称为FADEC),是指挥发动机 的大脑。FADEC可以从发动机上的传感器中获取数据,对发动机进行一系列的复杂控制,如改变喷口面积、监控发动机状态、诊断故障等等。FADEC不仅能 够大大提高飞机的飞行性能,而且减轻了发动机的重量。在早期型号的涡扇10发动机上,由于中国自己则缺乏高性能涡扇发动机控制系统的研究经验,就把俄罗斯 发动机的控制系统移植到涡扇10上。

这种做法虽然在当年是够用的,但到如今,老式俄制发动机的控制系统移已经无法满足三代半战机和四代机的需要。在刘永泉团队的努力下,成功研制出全权限数字电子控制系统,使涡扇10发动机告别了AL-31F发动机的控制系统。

正如中航工业2015年社会责任报告中写道,“太行”发动机批量装备部队,中航工业已具备自主研发第三代大推力发动机的能力,涡扇10的可靠性问题,中航工业和军方已经用实际行动作了表述

AVIC report: China's Taihang engine widely deployed in military
By Jiang Jie (People's Daily Online) 14:45, July 07, 2016

China’s Taihang engines have become a significant, large-scale presence in the military, making China the third country in the world that has mass deployment of domestically-produced high-thrust engines for military use, according to the Aviation Industry Corporation of China (AVIC) annual report.

AVIC's social responsibility report showed that the company is capable of independently conducting research and development on the next generation of high-thrust aerial engines, along with advanced drones such as Wing Loong, which have also been deployed in the military.

The People’s Liberation Army (PLA) Air Force has deployed no less than 400 Taihang engines in five air force regiments. Various types of fighter jets are equipped with the engine, including the J-11B and J-15 carrier-based fighter jets, reported China Science Communication, a news site under the Chinese Academy of Sciences. So far there have been no crashes due to engine failure among Taihang engine-equipped fighter jets, the news site also noted.

Some doubts have been voiced about the originality of the Taihang engine, as there are people who believe the Chinese-made engine is a copy of its Western counterparts. However, according to China Science Communication, the development of the Taihang engine was based on accumulated experience and technological advances gathered since 1978. The engine was also based partially on its predecessor, WS-6, which spent some 20 years in development.

Meanwhile, the engine also took inspiration from the control system of Russia's AL-31F aircraft turbofan engine, China Science Communication admitted, calling the Taihang engine a result of “independent development combined with technology from the Soviet Union and the U.S.”

“China has become the fourth country in the world to independently design and produce large transportation aircraft, as well as the third country to independently develop stealth fighter jets,” the AVIC report said, adding that China has advanced its air-to-air and air-to-ground missiles to the fourth generation.
