Chapter 595 This efficiency is simply incredible

    "Lao Zhang, what you said is wrong. Attack-2 is a drone. According to what you said, a drone is not an airplane?" As soon as the air force leader named Lao Zhang finished speaking, a man who knew him well  The head of the army joked.

    Lao Zhang's old face full of vicissitudes of life showed no embarrassment at all. He just glanced sideways at the joker and said calmly: "I mean it's a manned plane, do you understand? It's a manned plane, hey~~ I'm telling you  It¡¯s useless to say so much, and you won¡¯t understand even if I tell you.¡±

    The joker was choked to death with just one sentence. Lao Zhang had no time to pay attention to that person. Instead, he looked at the wd-30s turbofan engine in front of him with burning eyes. Not only Lao Zhang, but also other commanders of the Air Force.  , even some of the leaders of the navy are the same.

    There is no way, it is actually the data of the wd-30s turbofan engine that allows these people to see the huge potential, 586dan, which is 586 kilograms of thrust. This indicator is not outstanding compared to ordinary turbofan power.

    But if you add the bypass ratio of 2.86, the thrust-to-weight ratio of 4.12 and the overall weight of 142 kilograms, it will be different.

    Because the bypass ratio of this type of small turbofan engine is usually between 1 and 2, and cannot exceed 2.5 at most, otherwise the overall quality will not be controllable and it will easily cause overweight, thus affecting the thrust-to-weight ratio.

    Therefore, around the world, the thrust-to-weight ratio of turbofan engines installed in integrated cylindrical missiles such as Attack-2 is generally around 3.2 to 3.5. For example, the F-121 turbofan engine used on the American Tomahawk cruise missile  That's it.

    The MS400 turbofan engine used on the Soviet Union's X-59 cruise missile has increased the thrust-to-weight ratio to a high level of 4.7, but accordingly, the service life has been greatly reduced, only more than 20 hours, which is comparable to the X-59 cruise missile.  It has flown the entire voyage and is not recoverable.

    The specific indicators of the F-121 turbofan engine on the American Tomahawk are not as violent as the MS400 turbofan engine, but the advantage is that the output is stable, and it can be recycled and reused in daily exercises or test firings. In this regard, the Americans are better than the Soviets  Better at living.

    However, from this perspective, the wd-30s turbofan engine does not have many advantages, because the total mass of neither the American F-121 turbofan engine nor the Soviet MS400 turbofan engine exceeds 100 kilograms, and the total thrust is not  They are all under 400 kilograms, and their service life is not very long, because they have to be prepared to die with the cruise missile at any time, so it is not cost-effective to have such a long service life.

    On the other hand, the wd-30s turbofan engine has a service life of at least one thousand hours. It is obviously not designed for missiles, but it is precisely because of this that Lao Zhang and others pay more attention.

    Because both the bypass ratio and the thrust-to-weight ratio are similar to the data of domestically produced intermediate trainer aircraft selected by the Air Force and Naval Aviation.

    Speaking of trainer aircraft, the aviation officers of the navy and air force also have a headache. When the mid-level trainer aircraft development project was launched in the mid-1980s, the tfe731 turbofan engine of the American Honeywell company was originally selected.  At the end of the decade, due to well-known reasons, the intermediate trainer project encountered the same difficulties as the Army Aviation S-70 helicopter spare parts.

    "You can buy it if you insist on buying it, but the price is so expensive that it makes people doubt their life. No one's money comes from the strong wind, not to mention that the country is not rich yet, so there is no choice but to leave it alone.

    This is not good news for the navy and air force aviation units, which already lack professional trainer aircraft, but the country cannot produce them for a while. Even if the navy and air force are in a hurry, they have to wait.

    The result was waiting, so they saw the wd-30s turbofan engine in this exercise organized by the headquarters. The bypass ratio of 2.86 and the thrust-to-weight ratio of 4.12 are not much different from the tfe731 turbofan engine.

    The only thing lacking is thrust. The wd-30s turbofan engine is 586 kilograms, while the tfe731 turbofan engine reaches 1.6 tons. The difference between the two is three times.

    But the problem is that the size and weight of the tfe731 turbofan engine is almost two to three times that of the wd-30s turbofan engine. If Ascendas Group can improve on the wd-30s turbofan engine, it should be no problem to satisfy the mid-level trainer aircraft.  At least it can solve part of the emergency transition.

    At the same time that Lao Zhang and others became eager after listening to the basic data, the head of the headquarters learned the basic situation from several technical staff and made up his mind to go to Ascendas Group after the exercise. No.  Speaking of other things, the WD-30S turbofan engine alone was worth him going over to take a look at.

    Having made up his mind, the head of the headquarters ignored the gathering of Lao Zhang and others to discuss the WD-30S turbofan engine, and did not dwell on this issue. There was no way, there was no professional in the field of aerospace development at the scene.  It would be more cost-effective to waste time here and go to Ascendas Group to ask Zhuang Jianye.

    So the head of the headquarters simply mentioned a few words, and after getting a few ambiguous answers, he changed the topic.?, then continued to ask Hou Yuejin: "The inaccuracy of the portable air defense missile has been solved. What happened to the other electronic jamming failure? The Blue Army's report said that the attack-2 drone controlled the control at the moment when it released the jamming.  The signal disappeared, but the Attack-2 drone is more flexible than before. What is going on?"

    Except for Lao Zhang and the others who were really attracted by the WD-30S turbofan engine and were still discussing in low voices, everyone else was attracted by the words of the head of the headquarters, but this time there was no need for Hou Yuejin to answer. The gaze from before  The upright leader of the Second Artillery Corps said in a low voice: "Should the optoelectronic terrain matching system be used?"

    After hearing this, Hou Yuejin immediately nodded like a chicken: "Yes, that's it."

    "Then there's nothing to say. We rely on photoelectric image conversion to identify paths. There is no electromagnetic wave escaping. How can this interfere?" The leader of the Second Artillery Corps nodded and then turned to the head of the headquarters: "Terrain matching technology is cruise missile navigation and  As for the key technologies of guidance, we have jointly researched with dozens of domestic scientific research units and achieved some results. Ascendas Group also participated, and what we are doing is optoelectronic image terrain matching technology.

    To put it bluntly, it compares the photographed photoelectric effect with the pre-entered electronic map, and then controls the flight of the aircraft based on the comparison. The Laser Research Institute under Ascendas Group has deep attainments in the field of optoelectronics and has made great achievements in optoelectronic terrain matching.  Progress, we are preparing to install them on the ends of several types of low-speed missiles. We are still testing them, but we didn¡¯t expect that they have already applied them to the Attack-2 UAV. This is really"

    The leader of the Second Artillery Corps shook his head and smiled bitterly as he spoke. He couldn't help it. He really felt that the conversion rate of Ascendas Group was so bad that he didn't know what to say. The low-resolution photoelectric terrain they issued to Ascendas Group  How long does it take to match a civil license?  It seems that less than a month ago, this was used on the Attack-2 drone.

    After earning a wave of R&D funds from the aerospace department, he used the results to slaughter the airborne troops in a blink of an eye. Looking at the fiery eyes of the heads of other services and arms, it is estimated that Ascendas Group's murderous knife will have to be stabbed several times. This efficiency,  Simply
