Chapter 450

Compared with the previous 200 HP piston engine, the power of the d-30wl turboprop engine is 645 kW, and the shaft horsepower is 876 HP.

It not only surpasses the domestic similar UAVs in the past, but also surpasses the zeus-3 exported to Europe by Tengfei aviation manufacturing corporation and the bullet a exported to the United States.

After all, Europe's zeus-3 uses a low-power version of Honeywell's turboprop engine, with a maximum power of 428 kW and a shaft power of 581 HP, which is in the same level as the d-30at designed by Tengfei Aviation Manufacturing Corporation for UAVs.

Compared with the high-power d-30wl turboprop engine, it is still one level behind.

As for the bullet a exported to the United States by H company, it doesn't even use the turboprop. It's just equipped with a 400 horsepower turbocharged piston engine, which is inferior to the zeus-3 in Europe, let alone the wuzhen-8a.

In addition to the supercritical wing of the uav-8a, more than 40% of the carbon fiber composite materials are used, and the advanced UAV remote control and data transmission technologies in Europe and the United States have been absorbed by Tengfei aviation manufacturing company in recent years.

Although the uav-8a is only a UAV, it is a master of many advanced aviation technologies of Tengfei aviation manufacturing company.

Even in a sense, wuzhen-8a is the highest level of Tengfei aviation manufacturing company. Compared with yun-6, it has to stand aside.

In fact, it is true. Although Tengfei aviation manufacturing company has made disruptive innovations in the fuselage structure of yun-6, yun-6 can achieve a 2.3-ton load and a maximum range of more than 2200km with a turboprop engine under a take-off weight of less than five tons.

However, compared with wudian-8a, it is still a little worse. After all, the structural material of yun-6 fuselage is a kind of cost control material, and the most advanced all carbon fiber composite material is not applied.

Wuzhen-8a not only uses T700 Carbon fiber material for the nose fairing, but also uses the aramid paper honeycomb structure for the back plates on both sides. The skin of a pair of wings is also made of T700 Carbon fiber composite material. With the aluminum lithium alloy beam inside, wuzhen-8a's supercritical wing performance has a qualitative leap compared with the previous generation of wuzhen-8.

If it is not that the air force surveying and mapping brigade does not have a comprehensive understanding of the performance of carbon fiber composite materials, and is worried that the application of a large number of new materials will affect the stability of ufda-8a, according to Zhuang Jianye's theory, they would like to use carbon fiber composite materials for the whole machine. After all, it is a UAV, which does not involve personnel safety issues. So they can play how they want to play.

It's a pity that the gold owner disagreed, and Zhuang Jianye and others had to give up. Even so, wuzhen-8a, let alone in China, is also the most widely used machine for composite materials in the world.

With the blessing of so many black technologies, the performance of the ufda-8a is absolutely the best among UAVs, with a maximum speed of 438 km / h, a maximum practical lift of 13600 meters and a endurance of 16 hours.

Together with the Dongfanghong series of communication satellites and several foreign commercial communication satellites leased by the headquarters, wuzhen-8a can cruise the whole territory without the limitation of communication distance.

In addition, due to its large volume, light structure and 1100 kg payload, the platform can be installed in different reconnaissance equipment according to different mission requirements.

Of course, with so many things pressing the bottom of the box, the cost of the whole system of wudi-8a is frighteningly high, reaching 8 million yuan.

However, the air force surveying and mapping brigade didn't even frown at this. It directly gave Tengfei Aviation Manufacturing Corporation 10 million yuan to purchase a complete set of systems including six non detection-8a and ground control receiving devices.

It's not that the air force's surveying and mapping brigade has become a big man who can smash 10 million people. It's really that the air force's investigation methods are too scarce at this time. It's not only unable to provide support to the brother troops, but also the air force doesn't know what the superior asked.

Especially during the self-defense counterattack in southern Xinjiang, the reconnaissance planes of Annan and the Soviet Union frequently crossed the border, but the air force took out similar planes to go deep into the enemy for reconnaissance.

The main reason is that there is no one to take advantage of. The legs of J-6 and J-7 are too short. The J-8 is not stable. The targets of H-5 and H-6 are too big. In the past, they were living targets, and there were no suitable ones. Coupled with the lack of supporting reconnaissance equipment, the role of the air force in the operations in southern Xinjiang is not prominent.

Based on this, both the headquarters and the air force urgently need to improve the existing reconnaissance capability of the air force, and the non reconnaissance-8a meets the needs of the air force to strengthen the reconnaissance capability from all aspects.

So not to mention 10 million, even 20 million air forces are tightening their belts.

What's more, 10 million or 20 million is really not expensive for a high-altitude UAV, which is like a reconnaissance satellite, can hover over the enemy all the time and focus on every move of the place.

The cost of a reconnaissance satellite is 10 to 20 million yuan, and the time for the satellite to pass the zenith has to be calculated, so the flexibility is much less. Wudian-8a is different. It is equipped with the same infrared optical and synthetic aperture radar as the reconnaissance satellite. It hovers back and forth in an area at an altitude of more than 10000 meters. It will never stop until the enemy's heart, liver, spleen, stomach and kidney are clearly seen.What's more, at the same price, there are six wudi-8a and only one satellite.

The air force surveying and mapping brigade has also considered whether it will be beaten down by the enemy as a living target. However, in the end, it still thinks that it depends on the specific tactics. If it is rigid, even the most advanced equipment will be beaten down. If it is fully prepared and flexible, the enemy may not be able to succeed.

In fact, it is true that during the subsequent operations in southern Xinjiang and the recent disaster relief in southern Tibet, the non detective-8a of the air force surveying and mapping brigade played an irreplaceable role.

In March, during the battle in southern Xinjiang, the four non detective-8a carried out 20 hours of uninterrupted reconnaissance on the Annan stronghold on one side of the border. They kept 32 fixed fire points, four artillery positions, and two reserve forces assembly points in sight. In addition, they also provided three secret mountain roads not marked on the map for the offensive troops.

As a result, the offensive force was not only fierce, but also unexpected, so that before Annan's troops understood what was going on, their fighting forces were pulled out.

Until now, Annan didn't understand what method China used to touch them so clearly, so that their reserves were covered by heavy artillery fire from China several times as soon as they assembled.

The officials of New Delhi are also puzzled. It is reasonable to say that in the name of the exercise, they store up heavy troops at the border. Under normal circumstances, even if China does not hold an exercise of the same scale, it will be on guard. After all, there are many variables after the flash flood disaster, and no one will be on guard.

As a result, it is time for China to provide disaster relief, resume production and resume production.

What New Delhi officials don't know is that as early as before China's disaster relief, the air force's aerial surveying and mapping brigade had already used the non detective-8a to see the New Delhi side clearly along the Himalayas.

What if there are more troops? What about the exercise? The mountain torrent broke out and destroyed all the roads used for logistics supply. Are the trapped officers and soldiers still officers and soldiers? It's a fiscal black hole that can't be filled out.

So it's better for you to take your time in New Delhi. There's no time to deal with it here.

It is the efficient and accurate early detection of non detective-8a that makes the subsequent disaster relief work so fast, efficient and fearless.

Today, just after the forest fire in Daxing'anling, the air force surveying and mapping brigade in the southern Tibetan area is once again in danger. It manipulates the non detection-8a to rush to the fire site. As a super versatile man, it undertakes the technical investigation tasks of meteorological detection, terrain exploration, fire monitoring and so on.
