Chapter 1426 ¡°Lancang River¡± Project

Previous page        Return to Catalog        Next page

    As soon as he finished speaking, three big characters "Lancangjiang" with flying phoenixes appeared on the screen!

    ¡°This is a brand new aero engine built by our China Ascendas Aviation Engine Group, with a cruise thrust of 72 tons, an afterburning thrust of 125 tons, a total mass of 1.38 tons, and a thrust-to-weight ratio of 9¡­¡±

    Tang Lili held a laser pointer and introduced the basic situation of the aircraft engine on the screen, but the experts and navy leaders present were no longer stunned, but were completely petrified on the spot.

    To be more precise, when the three words "Lancangjiang" appeared on the screen, many senior people who knew the domestic aviation industry were shocked and speechless, especially Huang Feng and other people in the Northeast aviation industry.  The people in the group almost dropped their jaws to the ground.

    Immediately, a series of questions appeared in my mind like a screen

    ¡°Isn¡¯t the ¡°Lancang River¡± project suspended?  Why does China still insist on taking off?

    Isn¡¯t the aviation industry determined to mainly imitate Russian-made al-31 heavy-duty aircraft engines?  Why is China trying to start a new business after taking off?

    The most important thing is that the national level of heavy-duty aero-engines obviously only supports the aviation industry. Where does China Takeoff get the funds?

    In fact, it was not just Huang Feng and others who had this question. Almost all of the other people present were different from China Tengfei who actually came up with the "Lancangjiang" project, which is supposed to be a backup plan for the al-31 aero-engine imitation project.  , with the overall progress of the imitation going smoothly, the spare-tire "Lancangjiang" should have been in the cold palace for a long time. Why did it appear in front of everyone so suddenly?

    So much so that everyone in the venue felt as if they had seen a ghost, and it was difficult not to be shocked.

    The reason for this is very simple. The "Lancangjiang" aero-engine project should not appear here as a project that has been de facto canceled.

    And the twists and turns are complicated.

    As China Ascendas made great progress in the field of aviation development, it gave the troops more choices. Therefore, when China Ascendas launched the development of the third-generation core aircraft in the 1990s, it made breakthrough progress and even made a thrust-to-weight ratio of  After the experimental medium-sized aircraft of 9, the army adjusted the development strategy of heavy-duty aero-engines, that is, focusing on the Aviation Industry Group, which was previously reorganized by the Ministry of Aviation Industry, and adjusted it to a pattern of equal emphasis on the Aviation Industry Group and China's take-off.

    The specific situation is that the Aviation Industry Corporation of China is taking the lead in copying the Russian-made al-31 heavy-duty aeroengine; China Takeoff is the core to develop domestic heavy-duty aeroengines, which is the so-called "Lancang River" project.

    The original dual-line layout has developed well. Even in the mid-1990s, China Takeoff had already built the wd-70 heavy-duty aeroengine using the third-generation core aircraft, with an afterburning thrust of 128 tons and a thrust-to-weight ratio of 8.5.  The performance index is no less than that of the Russian-made al-31. In particular, the fuel consumption ratio is much better than that of the al-31. Therefore, it has been praised by many military leaders such as the head of the headquarters.

    If this technological path continues to develop, the wd-70 heavy-duty aeroengine will inevitably mature and become the preferred power source for Project 10, new carrier-based fighter jets and even next-generation combat aircraft.

    But the problem is that there is an "if" before this assumption, which means that everything is illusory.

    This is indeed the case, because in the second half of 1998, the headquarters organized an expert group to conduct a thorough investigation of the progress and maturity of the two heavy-duty engines. It was found that although China's Tengfei WD-70 heavy-duty aeroengine had technical  Advanced and outstanding capabilities, but the maturity of the overall technology path based on the third-generation core machine is low.

    In contrast, although the imitation version of al-31 is not technically advanced, its overall maturity is relatively high and can fully meet the needs of domestic heavy-duty aeroengines in the next 20 years.

    The reason why the expert group came to this conclusion is based on their half-year high-altitude bench test of the two engines.

    But precisely because of this, it also exposed the shortcomings of China¡¯s lack of foundation for take-off.

    After all, there was only one aero-engine high-altitude test bed in China at that time, which was affiliated to the Aviation Industry Corporation of China.

    When there is no obvious competition between China Takeoff and China Takeoff, the high-altitude platform can naturally be opened to China Takeoff. Because of this, China Takeoff is developing relatively smoothly on its second-generation core aircraft and 2.5-generation core aircraft.

    But when it comes to heavy-duty aero engines, the two sides have an obvious competitive relationship. Although the Aviation Industry Corporation of China has not explicitly prohibited China Takeoff from using its high-altitude test bench, it has made many small moves in approval and scheduling, resulting in China Takeoff's first  The development of the third-generation core machine is far behind the planned plan.

    That¡¯s it, competition is everywhere. As long as we can make the latest WD-70 heavy-duty aeroengine, it will be worth it. However, the house leaks and it rains continuously.However, at this critical moment, the Russians gave the WD-70 heavy-duty aeroengine a fatal blow.

    Because the Russians, who had previously kept a tight lid on the technology of the al-31 heavy-duty aircraft engine, suddenly began to open the door to cooperation with the Aviation Industry Group. They not only opened up the supply of related parts and components of the al-31 heavy-duty aircraft engine, but also transferred core technologies to the aviation industry group.  Take it out and share it with the Aviation Industry Group.

    ¡°As a result, the al-31 heavy-duty aircraft engine that originally took ten years to complete can be completed in less than five years and put into mass production.

    ¡°This time, not only the Aviation Industry Group was excited, but even the entire army was excited.

    We must know that heavy-duty aero engines are the biggest shortcomings of today's aviation forces. The sooner they are solved, the earlier the production bottleneck of J-10, J-11 and other advanced fighters will break through the upper limit. This will have a great impact on the preparation for military struggles on the southeast coast and the impact of anti-access operations.  The strategic significance is immeasurable.

    Based on this, the headquarters, which was originally a bowl of water, began to shift resources to the Aviation Industry Group and fully supported the imitation project of the al-31 heavy-duty aircraft engine.

    Seeing that the country attaches great importance to it, Russia actively cooperates. Not only does it jointly establish a joint venture with the Aviation Industry Group, but it also dispatches a large number of technical personnel to assist the Aviation Industry Group in completing the imitation of the al-31 heavy-duty aircraft engine. To this end, the framework agreement signed by the two parties,  There are more than 500 cooperation intentions and specific contracts.

    In such an atmosphere, domestic public opinion's favorability towards Russia has soared. Some people in the industry have even compared the cooperation between Russia's State Aerospace Engine Group and the Aviation Industry Corporation of China in the field of aviation to the Soviet Union's technological export to China in the 1950s.  , a highly praised ability.

    But in fact, the Russians are not so kind. The reason why they changed their previous blockade on aviation engine technology and began to seek cooperation is that they saw that China's take-off WD-70 heavy-duty aeroengine is about to get on the right track. If this is not strangled  , Russia will completely lose China's heavy-duty aircraft engine market. In this case, there is nothing to hesitate. Naturally, how can it quickly kill the WD-70 heavy-duty aircraft engine?
