Take Off My Aviation Era

"Lao Zhang, what you said is wrong. Attack-2 is a drone. According to you, a drone is not an airplane?" The air force leader called Lao Zhang just fell off, and someone knew him well. The head of the army joked.

Lao Zhang’s old face full of vicissitudes of life is not at all embarrassing at all, just squinting at the joking person, with a calm expression: "I mean someone pilots a plane, understand? Someone pilots a plane, hey~~ tell you So much is useless, and you don’t understand it."

Just one sentence choked the joker. Zhang didn't have the time to talk to him. Instead, he stared at the wd-30s turbofan engine in front of him with scorching eyes. Not only Zhang, but also other chiefs of the Air Force. , Even the leadership of a part of the navy is the same.

No way, it is the data of the wd-30s turbofan engine that let these people see huge potential, 586dan, which is 586 kilograms of thrust, this indicator is not outstanding compared to the general turbofan power.

But if you add a bypass ratio of 2.86, a thrust-to-weight ratio of 4.12, and a total weight of 142 kg, it will be different.

Because this kind of small turbofan engine usually has a bypass ratio between 1 and 2, and cannot exceed 2.5 at most, otherwise the overall quality will be uncontrollable and it will easily cause overweight, thereby affecting the thrust-to-weight ratio.

Therefore, in the world, the thrust-to-weight ratio of the turbofan engine installed in the integral cylindrical shell of the Attack-2 is generally about 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 X-59 cruise missile has increased the thrust-to-weight ratio to a high of 4.7, but correspondingly, the service life is also greatly reduced, only more than 20 hours, which is enough for the X-59 cruise missile. Fly the entire voyage, and it 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 victory lies in the stable output. Daily exercises or test shots can be recycled and reused. In this respect, the Americans are better than the Soviets. Will live better.

However, from this perspective, the wd-30s turbofan engine does not have many advantages, because the total mass of the f-121 turbofan engine in the United States or the ms400 turbofan engine in the Soviet Union does not exceed 100 kg, and the total thrust is also They are all under 400 kg, and their service life is not very long, because they have to be ready to die with cruise missiles at any time, and it is not worthwhile to make such a long service life.

On the other hand, the wd-30s turbofan engine has a service life of at least a thousand hours. It is obviously not born 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 the domestically-made intermediate trainers selected by the Air Force and Navy Aviation.

Speaking of the trainer aircraft, the chief aviation officers of the Navy and Air Force also have a headache. The mid-80s development project for the intermediate trainer aircraft was originally selected to be launched by Honeywell’s tfe731 turbofan. At the end of the decade, due to well-known reasons, the mid-level trainer aircraft project and the Army Aviation S-70 helicopter parts encountered difficulties.

If you just can buy it, you can buy it, but the price is so expensive that you can doubt your life. Nobody's money is brought by the wind, not to mention that the country is not rich now, and there is no way but to run aground.

This is not good news for the navy, air force, and aviation units that lack professional trainers. However, the domestic air force cannot do it for a while. The navy and air force are in a hurry and have to wait.

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

The only thing lacking is thrust. The wd-30s turbofan engine is 586 kg, while the tfe731 turbofan has 1.6 tons, which is three times the difference.

But the problem is that the size and weight of the tfe731 turbofan engine are almost two to three times that of the wd-30s turbofan engine. If Ascendas can improve on the wd-30s turbofan engine, it should be no problem to meet the requirements of the intermediate trainer. At least part of the emergency transition can be resolved.

The head of the headquarters learned the basic situation from several technical staff at the same time when Lao Zhang and others became eager to listen to the basic data, and he made up his mind to go to the Ascendas Group after the exercise, no In other words, relying on the wd-30s turbofan engine is worth his visit.

Made up his mind, the head of the headquarters did not bother Lao Zhang and others gathered to discuss the wd-30s turbofan engine, and did not entangle on this issue. There was no way. There was no professional in the field of aviation development. It's better to waste time here than to save up and go to the Ascendas Group to ask Zhuang Jianye for a good deal.

Therefore, the head of the headquarters simply mentioned a few words, got a few ambiguous answers, turned the topic around, and continued to ask Hou Yuejin: "The inaccuracy of the aiming of the portable air defense missile is solved. Another electronic jamming failure is What's the matter? The Blue Army's report said that the control signal disappeared when the Attack-2 drone released the interference, but the Attack-2 drone was more flexible than before. What's the matter? "

Except for Lao Zhang, who were really attracted by the wd-30s turbofan engine, they were still discussing in a low voice. Everyone else was attracted by the head of the headquarters' words, but this time it was useless for Hou Yuejin to answer. The previous gaze The upright leader of the Second Artillery Corps said in a low voice: "The photoelectric terrain matching system should be used, right?"

Hearing this, Hou Yuejin immediately nodded his head, "Yes, that's it."

"Then there is nothing to say~www.readwn.com~ Relying on photoelectric image conversion to identify the path, there is no electromagnetic wave escape, how can this interfere?" The leader of the Second Artillery Nodded, then turned to the head of the headquarters: "Terrain matching Technology is the key technology for cruise missile navigation and guidance. We have achieved some results in joint research with dozens of domestic scientific research units. Ascendas Group also participates in the photoelectric image terrain matching technology.

To put it bluntly, it is to compare the photoelectric effect of the photo with the pre-input electronic map, and then control the aircraft to fly according to the comparison situation. The Laser Research Institute of Ascendas Group has deep knowledge in the field of photoelectricity and has achieved great results in photoelectric terrain matching. Progress, we are now preparing to install several types of low-speed missiles at the end. It is still testing, but I didn’t expect that they have already been applied to the Attack-2 UAV. This is really..."

The leader of the Second Artillery Corps shook his head and smiled bitterly as he talked. He really felt that the conversion rate of Tengfei Group really made him wonder what to say. They gave Tengfei Group a low-resolution photoelectric terrain. How long does it take to match civilian licenses? It seems that it hasn't been more than a month, and this used the Attack-2 drone.

Earning a wave of research and development funds for the aerospace department, I took the results to kill a pass of 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 the Ascendas Group would have to stab people for several rounds. This efficiency, It's almost...
