open bar phrase: we can not see their work in the front, their selfless dedication and the aviation industry closely linked to the cause of national defense weapons and equipment, and today, when we approached them – this particular crowd, empathy is their gold-like quality, this quality, like inspirational beacon to guide us the road ahead.
he is the sea, Dr. aircraft engines installed, he was involved in negotiating the introduction of an engine to save the country tens of millions.
he was involved in supervision of the “Mountains” engine, so that our country has a powerful symbol among the air, fill the volume of China’s high-thrust turbofan engine industry gap.
he led the 12 key technology breakthrough in the results to solve a series of air power protection problems.
his personal army of Quality Supervision, advanced, advanced individual learning to become the Navy, installed three into the sea model, the first prize of national defense science and technology, military science and technology progress prize winner … ….
he is the sea-installed chief representative of the West Anmou Jun Ye Xinnong Representative Office, over the years, he has always pursued: the life entrusted to the engine, lifted sky Flying Leopard tsunami, is the most fortunate thing in this life.
everyone judge the value of life standards.
Ye Xinnong values ??are lofty: “Life is the highest level to serve the motherland. To participate in development of Chinese fighters in the heart of China, the glory of my life.”
develop a fighter general need 15 years to develop a fighter “heart” is to use at least 20 years. In 2000, Ye Xinnong ordered to lead China’s first domestically turbofan engine, “Mountains” related development work. In March 2001, the engine made 150 hours of research into the limits of the stage of assessment load durable. Only passed, the level of aviation technology to meet the design requirements, be considered with the engine developed industrial base.
However, the first critical test, let the development work came a cropper. The final stage of testing, almost succeeded when the blade was broken, the test was forced to pause. Issues surrounding the investigation, the military opened a plant I do not know how much the two sides will be, debated. To find out the reason, Ye Xinnong holding foreign materials, the introduction of machine failure to digest the scene, corrective measures and design changes, from parts to finished mold parts, to each his pipe, each set of data compared with the introduction of information one by one, found small rounded leaves exhaust side, to continue the investigation, also found that the leaves bruised cause stress concentration due to fracture. While factory workers praised the attitude of its detailed work, he opened a series of “prescription”: strengthening the process manufacturing standards, increase testing inspection, parts inspection and strict control of working capital, development of special tooling inspection … a small local deformation of leaves, allows Ye Xinnong led to an aviation process of technological change.
military representative responsible for quality supervision, is ruthless.
can Ye Xinnong overspill work but everywhere the truth, he sentiment: “Even if a blade is a spiritual, with emotions to understand them, to good quality.”
an accurate clock to go, every second must be accurate. Ye Xinnong insist, is such a quality concept.
2005, the first delivery test, the engine holds the main oil pump shaft fracture occurred, and the intermittent failure occurs, regardless of how both the military plant validation checks have not found the real reason. In desperation, Ye Xinnong what brought the introduction of the original check. This foreign parts to find out is “bundling process,” the five parts coaxial fixed up for processing, to ensure cooperation and tolerance between the parts accuracy. This ratio, the level of technology than a gap, “parts like people need to act in harmony” and to let Ye Xinnong every acceptance, as is always the first to know about child-like parts, the matching between the parts diagram put in the side and grasp the spiritual, the production process has to solve the 23 problems.
the past few years, he has steadily promote the factory introduced the “technical quality of the engine assembly process”, “job-site set-regulations”, “small parts management system” and other standards, to promote plant management significantly improved. Year, he has organized more than 120 technical quality of research, more than 70 technical improvements, improved forging die 15, significantly improved the passing rate of engine parts, to solve a series of domestic problems in the process.
in Ye Xinnong mind, “responsible for the lives of his comrades,” is never empty.
For him, the concept of family also includes thousands of miles away pilot brother,
He often said: “We are more of a hard, less of a military loved ones dangerous. “
2006 year, a group of military aircraft fuel consumption high, affecting aircraft performance play. If not improved, it means the burden of training and preparation of troops. Ye Xinnong decided to stand, “fuel consumption is not resolved, would have compromised aircraft combat radius, and then have to bear a large risk!” He set up joint factory survey research team, dozens of days of continuous statistical analysis of more than 100 sets of engine test data, and with reference to the introduction of machine technology, state the reasons for each screening of high fuel consumption. Improvements in the stage of validation, a huge roar of his squat in the test site for the test to distinguish the subtle changes, he breaketh the eardrum braved the danger and insisted on wearing earmuffs abnormal sound check to listen to. Analysis of numerous day and night, overtime test numerous times, three months later, the “gas guzzlers” in Ye Xinnong front, chose to retreat.
to reduce the burden of maintaining forces, Ye Xinnong always concerned about the force of the idea of ??warmth.
he repeatedly emphasized to the representatives of the military: “To force more familiar with, understand force, make it more useful for the military measures to solve problems.”
engine life management and maintenance of dozens of years has been a headache for troops two problems. To address this industry problem, Ye Xinnong decided to apply for a professional, Northwestern Polytechnical University, Dr. aircraft engines. His reference to foreign engine maintenance practices, began a “life of the engine control unit and body repair” in the research and came up with an engine life sentence, maintenance rules, and led the first set of “engine life management evaluation criteria,” at least repairs for the troops to save $ 3 million.
2006 年 to 2007, Ye Xinnong running all over the naval air force, the engine failure, force protection capability, maintenance requirements of recording, extensive collection of foreign armed forces to protect the new tools, launched a “simple field test engine system “in the research. In June 2008, the first simple test system has successfully implemented a field test engine, greatly increasing the efficiency of field maintenance. Then he took the initiative to undertake R & D engine cycle parameters and recording devices to automatically record data during the engine life consumption, the use of force required to be listed as essential accessories. There engine integrated detector, the use of IPC and digital detection technology, the engine automatically, comprehensive and efficient detection by the military alike.
2007 December, “Mountains” engine setting the formal adoption of the production, Xiao red sky. Ye Xinnong gentle face in front of everyone, but, frankly wept, crying so invested. 19 years young, has “Mountains” is the name and into his life, engraved in his heart. He used 19 years of youth, a contemporary interpretation of the profound meaning of the core values ??of the military.
