Editor’s note: strong, the aviation engine strong. Accelerate the development of aircraft engines, aviation’s mission is also the common expectations of the community. Recently, the “see the world”, “Study Times” and other media published an article by Comrade Tian Wenxin, “Why 60 years, China is still not making aircraft engines.” The author calm perspective, scientific attitude, rigorous analysis of aero-engine development must go through pre-research – trial – Verify – project – detailed design – Design stereotypes – stereotypes the whole process of production of this important objective laws, to sharp language that we For a long time development work on the aero-engine long-term, arduous and high-investment characteristics such as lack of clear understanding. Author of the history of thought-provoking memorial service for the aviation industry’s call admirable. This article is reproduced in order to motivate 400,000 people in the aviation industry of aviation on the road to innovation beyond crucial for the country as soon as possible to devote more and better engines and aircraft products, take concrete actions to achieve the “Air to serve the country, strong army enriching” the mission for the Chinese people to take off due to the history of aviation contribution.

China 60 years that made no aircraft engines?

text/Tian Wenxin

our children to put the entire aviation industry, not aid to Vietnam and our 1/10, a fraction of aid to North Korea.

2009 year is the 60th anniversary of the Chinese Air Force time, with a large number of F-10 fitted out in the Chinese Air Force into the 21st century, not only won the main equipment, the Chinese aviation industry has also trained a large number of this professional research personnel. But the most regrettable is: J-10 of the most critical part – the engine still uses the original Russian engine AL31 series, which became the aviation industry for decades of heartache.

Chinese aircraft “heart”

main force of China’s air force basic operational model is used in foreign power system, with the exception of equipment “Taihang” small engine F-11B fighter aircraft the use of domestic power system, all the new research aircraft are buying equipment or imitation of foreign engines. “Flying Leopard” fighter-bombers are using the generic British “Spey” engines of the turbofan 9 – “Qinling.” It can be said of China’s aviation industry has not been provided to any one of our air force developed its own type of aircraft engine models, and there has never been a model aircraft engine had completed the pre-research – trial – Verify – project – detailed design – Design stereotypes – stereotypes of research production process.

air behind the engine, has seriously hampered the development of the aviation industry, Air Force weapons development as a “bottleneck.” Can be said that no foreign power system, the main force of China’s air force can not fight off! This is our national security, peaceful rise, it is definitely a very grim reality and the urgent need to address the major issues.

aircraft engine is the highest level of technology on the planet, the core technology, the most stringent threshold, involving theoretical maximum depth, the overall structure of the most complex industrial products, dubbed “the flower industry.” Aircraft engines and aerospace industrial products of different rocket engines, rocket engine is a one-time product, and work up to hundreds of seconds, does not need to be very strong materials and process technology. And aircraft engines, especially the use of turbojet aircraft turbofan engine, the only life for decades (in accordance with Air Force aircraft engine life and national use), and poor working conditions, work status changes frequently.

power systems such as the United States, the first three generations of work F100-PW-100, the beginning of its development is not fully aware of the work of state aircraft engine conversion. After the troops in the combat training course, pilots often need to work at maximum engine speed is between the state and the lowest frequency conversion, the results of F100-PW-100 appeared a number of issues, but also the achievements of the F-15 fighter regular “lying nest . ” Therefore, the development requires a lot of aero-engine test to simulate the actual use, but more advanced materials and manufacturing processes to the achievement of this aero-engine industry title.

this loss we eat a big

the development of China’s aviation industry is really tangled too much bitterness and regret, first of China’s aviation industry has been Big Brother’s strong support for the Soviet Union, Soviet support for China’s all-industry ushered in China’s aviation industry to make the first spring. In Big Brother’s help, China can quickly build a world-class par and aviation industrial system, basically the Soviet Union’s new aircraft models and the introduction of the new power system once established will be able to copy a few years time setting. But not for the aviation industry in China and the aviation industry to develop a force from imitation to develop long-term planning, but will be limited to the aviation industry itself the task of imitation, production and repair.

China and the Soviet Union often have a specific project development model when we come to engage in basic research, exploration and development (applied research), pre-development and intends to adopt a dynamic model of the entire aviation industry’s progress. And we all know this road is not consistent with air force model developed by objective laws. The focus on European and American air power is extremely basic research and pre-research, I will summarize its powerful magic into three key words: pre-research project, the core unit plan, the engine series. In fact, the three key concepts and ideas is an integral whole, its constituent power of the developed countries in the development of the aviation system, the backbone of the whole idea.

In China, an engine model really began the real technical work related to project from the beginning. If you do not project, no engine required a lot of research and development funding. It means if the military does not project the engine model, associated with this type of basic research on the basic can not be carried out.

development of air power in developed countries while adhering to the “pre-research priority” approach to development, the engine is made in the development needs of the military before the aviation industry has developed their own processes for advanced technology exploration and research. When the proposed next-generation engine developed by the military needs of the time, the aviation industry has the relevant technology demonstrator, both play very skilled, and naturally the engine model will greatly shorten the development cycle, development risk is greatly reduced.

This F119 engine development process in the United States was reflected in the extremely obvious. In the F-22 “Raptor” aircraft development process, the aircraft weight and drag are increased considerably, for which the military requires a corresponding increase in engine thrust by nearly 17%, ie, the maximum thrust (afterburner) requirements for 156KN. Intermediate thrust (afterburner without opening the state’s maximum thrust) is 105KN. And the major changes and no great impact on their development cycle, because Pratt & Whitney engine has been launched ahead of the pre-research project. Upon receipt of the demand for performance after the engine, Pratt & Whitney directly from their own research and development technology in the pre-show research proven mature technology used in part to improve on the F119, soon to meet the military requirements. If such things happen in countries with insufficient pre-research work on the aero-engine developed enough to cause more than 5 years of delay, and may directly lead to engine failure developed.

development funding to North Korea less than a fraction of

in China due to the long generic production of aircraft engine condition for the objective laws of aero-engine developed a serious lack of control, aero-engine development work for the long-term, arduous and there is no clear understanding of a large investment. This results in the development of aero-engine research investment intensity is far below actual needs. For example, the early 1960s, China began to develop high-thrust turbofan turbofan engine 6, 606 according to statistics, only 20 years of development funding totaling $ 150 million, an annual average of 7.5 million. When entering a critical stage of development, requires high investment intensity, yet there are only two years, to 200 million, total investment and investment in such strength to the development of advanced large-scale power system is simply incredible air, but history is the truth.

in the last century, 90 years ago, we gave the child into the aviation industry, not aid to Vietnam and our 1/10, less than a fraction of aid to North Korea, and even less assistance to Albania! The same period, China imported Spey MK202 engine imitation, but to spend 13 billion yuan.

According to foreign experience, the typical engine development cycle of about 8 to 14 years, the entire life of the engine was approximately 30 years. Development funding in calendar year growth, according to engine size models, the development of different conditions, development funding at 500 million to 20 billion dollars. If the investment intensity does not guarantee, shelf life of the engine can not be developed on time out, the consequences of failure can only be developed, model horses.

long-term development of China’s aviation industry more is the root cause of poor decision-making inappropriate. Of course, our country was founded to develop nuclear weapons, missiles, space and time as the focus of no specific wrong, when the international situation is the hegemony of the Soviet nuclear weapons and the United States long shrouded the new Chinese shadow over the country to achieve a breakthrough on the nuclear threat of hegemony must be strategic rocket and missile industry has invested heavily on.

but this is not on that high-tech aviation industry, aviation industry is a simple production industry is a considerable understanding of fallacies. Until China’s high-tech development program – 863, aviation were not included among our focus on the development of the industry. Although the “air power” slogan resounded through the land of China, after all, but missed opportunities and wasted time and how to pay, how to trace? Loss of talent who is going to recover? In the history of the memorial service, often find the real answer. (Source: see the world)
