21 is the last day of the 2010 Zhuhai Air Show, Beijing aviation enthusiasts Zhengguo Hu reluctant to leave the front of large aircraft fuselage C919 1:1 prototype.
"The first time lifted the veil of the domestic large aircraft during the air show is the third time I watched." Zhengguo Hu said quietly, "from the cockpit control system, cabin seat to the kitchen, bathroom, could have put something installed, and can say that this is a big plane. but let us cherished, or domestic engine. "
Known as the "Pearl of industrial crown" of the aircraft engines, such as the nine units from the cowl body precision coupling, coupled with the outer casing pipe and accessories assembled. "Embedded made aircraft machine nacelle manufacturers, is that the people in the visual impression of a large aircraft 'heart'." AVIC I Commercial Aircraft Engine Co., Ltd. R & D engineer with the Southern engines, Summit said.
Commercial aviation engine must be addressed simultaneously high-speed, high pressure, ultra-high temperature the three major technical problems, the performance and skill levels for the whole aircraft, in security, economy, comfort and other key indicators are accounted for more than half the weight, the development technical difficulties, high risks, more investment, long period.
The world's civil aircraft engine market monopolized by the United States and Europe. Although developed for military aircraft engines have a certain basis, but in the civilian products, China has yet to explore a research and development to production from the full path. Major projects by country strategic decisions of large passenger aircraft, China has developed the first commercial aircraft engine project, try to large aircraft, the "heart" tackling difficult. The exploration of military aircraft engines, a major foothold.
During the air show in Zhuhai, China Aviation Museum Airshow engine exhibition, at the current progress of the overall design of the domestic production of three-dimensional animation engine, attracting visitors attention. In this, China's first exhibit common core machine thrust of 1,000 kg, 5,000 kilowatt engine turboprop, 500 kW 15 turboprop engines and a helicopter tail drive straight.
"China Aviation Museum exhibition highlight the engine series engine development. We will see our military aero-engine from the second generation to third generation, from which other major thrust to the thrust across." Aviation Industry Group Corporation Lin Zuoming on , told reporters.
As the core technology of large aircraft, made the engine has been shackled the development process of China's aviation industry. China Aviation Industry Group, deputy director of Science and Technology, Chinese Academy of Engineering, said Liu Daxiang, made large aircraft fitted with the "China Heart" Flying, roughly divided into two steps be implemented: the purchase of foreign-made large aircraft engines mature first flight, pilot, domestic engine developed simultaneously; replaced at the appropriate time the engine independently developed by China.
Liu Daxiang said that with the large aircraft project started, the relevant technology has made great progress, especially in the aircraft industry the establishment of commercial engine company, give us reason for China's large aircraft loaded as soon as possible, "Chinese Heart" blue sky full of confidence .
Engine called the commanding heights of the real competition in the aviation industry. From Canada, Brazil, China, global, large and small aircraft manufacturing lot, but basically the only civil aircraft engines from the United States, Western European countries to buy.
Earlier this year, the Commercial Aircraft Engine Co., Ltd. started R & D base in Shanghai Minhang District. The total construction area of about 30 million square meters, invested 3.23 billion yuan of the base, after the completion of a capacity of 2013, nearly 3,000 people, mainly large-scale development of 150-level C919 aircraft engines, will also meet the 250 class large aircraft engine development needs.
As the aircraft, the "Chinese Heart" the bearer of the development tasks, in the Commercial Aircraft Engine Co., Ltd. in Zhuhai, announced on behalf of China has established the highest level of aero-engine field, "national team", are now redoubling its efforts to carry out design, verification and key technology research, is expected to complete the first round of this year design.
"According to the development schedule, 'second five' during the assembly out of a complete, all indicators have reached the level of the next generation of the world's major engine demonstrator products." AVIC I Commercial Aircraft Engine Co., Ltd. Deputy General Manager Li Paul said.
The industry believes that, after the U.S., France, China will use high-performance, low cost, quality service and innovative model advantages, the progressive realization of domestic civil aviation engines. In the long run, the real goal is the world market.
"We also showed concern with independent intellectual property rights of China's full third-generation 'too line' turbofan engines, and 3000 kg thrust turbofan engine model, model of vehicle-mounted gas turbine generator sets, fully embodies the Chinese 'contribution to world development power 'of the firm conviction. "Lin Zuo Ming said.
