Chapter 1068

Seeing the head of the headquarters at a loss, Zhuang Jianye didn't know about the two operational modes of the fbc-1a fighter bomber. The Northwest Airlines factory hasn't reported it yet.

However, no matter whether they think that the two combat modes are too monotonous and want to make the report more attractive, or they want to give their superiors a big surprise and play with some thrilling little accidents, Zhuang Jianye can't care.

I didn't see that the 10000 word review of the head of the headquarters showed up. If we don't show up our own skills, let alone the funds and policies related to laser products, it's still unknown whether the 10000 word review can stand up to the head of the headquarters.

So without saying a word, Zhuang Jianye put the Northwest Airlines factory aside and nodded to the frowning head of the headquarters: "yes, chief, it's attack leopard. Because compared with the basic shape of fbc-1a fighter bomber previously submitted, attack leopard is equipped with wd-62suv medium thrust turbofan engine which is better than wd-62sm, and the thrust weight ratio is 6.5 times higher than that of wd-62sm 5, to 8 of wd-62suv, so that the engine cruise thrust can reach 5.8 tons, the normal maximum thrust is 6.5 tons, and the afterburner thrust can reach 8.8 tons. "

After a series of indicators from Zhuang Jianye's mouth, he was surprised to find that the head of the headquarters and other army leaders, as long as they know a little bit about aeroengines, are full of disbelief.

Even some leaders simply run to the rear of the body, or even simply lie in the intake port and look directly in.

There's no way. These leaders really want to see what this medium thrust aeroengine with a thrust to weight ratio of 8 looks like.

The value of thrust to weight ratio 8 contains too much meaning. The most direct thing is that the mass of the whole engine is much lighter than that of the wd-62sm previously reported.

Because the afterburner thrust of wd-62sm is 9 tons, although this value is larger than that of wd-62suv's 8.8 tons, it can't be said that wd-62sm is stronger than wd-62suv. After all, the thrust weight ratio of wd-62sm is only 6.5, and the weight of the whole machine reaches 1385kg.

The weight of the wd-62suv is only 1100 kg, 285 kg lighter than that of the wd-62sm. The weight of the two units is 570 kg.

It's heavier than a gsn-500 joint defense zone precision strike weapon.

That is to say, wd-62suv engine has higher energy density and stronger unit thrust. Even if it is 0.2 tons less than wd-62sm in Afterburner thrust, it is not in the same level in terms of comprehensive weight reduction and unit efficiency.

What's more, in addition to the afterburner thrust, the normal maximum thrust and cruise thrust of wd-62suv are much higher than that of wd-62sm. As for the original SBY mk202 turbofan engine of fbc-1 fighter bomber, there is no comparison.

You should know that the single weight of Spey mk202 turbofan engine is as high as 1850 kg.

Compared with Spey, the wd-62suv engine has a weight loss of 750 kg, and the twin engine is a full 1.5 tons.

The fbc-1a fighter bomber can reduce its weight by 1.5 tons compared with the old model, which is the same as the plug-in for the aircraft.

It's true.

Fbc-1a fighter bomber adopts wd-62sm aeroengine, and its target is to carry 8 tons of ammunition. When carrying out high attack profile, its operational radius is 1860 km.

The operation radius is 1187 km when carrying out low and ultra low altitude attack profile.

Don't underestimate the 8 tons of ammunition. The maximum load of domestic H6 bombers is 9 tons, which is known as the existence of bombers.

The Su-30MKK fighter bomber imported from Russia is only a maximum load of 8 tons.

Therefore, when the original version of wd-62sm aeroengine used by fbc-1a fighter bomber was reported, both the headquarters and the Navy and air force were very satisfied with the index of the prototype version.

It is believed that there is an additional domestic fighter bomber that can carry 8 tons of missiles, has an average operational radius of 1500 km, can carry out a variety of ground attack tasks, and can be completely autonomous and controllable, which plays an important role in the capacity building of Navy and air force aviation forces and the ability of multi task execution.

Unexpectedly, the original wd-62sm engine turned into a wd-62suv aeroengine, and the maximum missile load of 8 tons soared to 12 tons.

From this also formed the so-called prototype version and attack leopard two models.

To be honest, it would be hard for the head of the headquarters to believe that all this was true if he had not seen it with his own eyes and heard it with his own ears.

Not to mention the head of the headquarters, even Zhuang Jianye didn't expect the prototype version of the project to come out with attack leopard. There's no way. It's not that they really want to give a big surprise to their superiors, but that the 11 MW core machine of the second generation core machine high configuration version of Tengfei group has made a breakthrough. The new generation of medium thrust engine developed on this basis has immediately become a new benchmark.In contrast, the wd-62sm, which uses the second generation low configuration version of the 6 MW core machine, is actually just an improvement of the Spey mk202.

The fan, compressor, and even afterburner are all imitated from Spey mk202, but the combustor and high and low pressure turbine adopt the 6 MW core engine of Tengfei group, which increases the temperature in front of the turbine, so that the thrust is no less than the original version of Spey mk202, and the quality of the whole machine is greatly reduced.

In addition, the indexes of wd-62sm are not much higher than those of Spey mk202. It is no exaggeration to say that wd-62sm is the domestic copy of Spey mk202.

Because of this, the main production plant of wd-62sm is located in the engine production plant of northwest aviation factory. Tengfei group does not have large-scale production, but is responsible for the manufacturing of supporting 6 MW core aircraft. At best, it is just the important parts supplier of wd-62sm.

In contrast, the wd-62suv aeroengine is different.

This is the core military engine of Tengfei group at present. It is the driving force of many military combat aircraft developed by Tengfei group, including Jian jiao-7max, jzb-119, Zhenlong, etc.

Even when the third generation core aircraft is mature, some of the third generation core aircraft technology will be transplanted to the wd-62suv aeroengine, striving to raise the thrust weight ratio to 9 or even 11, so as to lay a foundation for the power of the next generation of medium combat aircraft.

Therefore, wd-62suv can be said to be the son of Tengfei group.

Now that my own son has been born, wd-62sm, which has been passed on to others, should give way.

Although Northwest Airlines disagrees with the idea of Tengfei group, after all, changing an aeroengine for a combat aircraft is not changing a wheel on a toy car, which requires a lot of Engineering rationalization calculation.

Thanks to Tengfei group's early preparation, the size and size of the engine are almost the same as wd-62sm, and can be successfully installed on the fbc-1a fighter bomber without any major changes to the aircraft.

And then Then northwest was captured by the law of truth again.

The fbc-1a fighter bomber with wd-62suv immediately had a qualitative improvement. Not only did the bomb carrying capacity increase from the previous 8 tons to 9.5 tons, but thanks to the excellent fuel consumption control of wd-62suv, its range also increased by 32% compared with the original version.

Because of this, when the attack leopard carries out the high and long-range profile attack mission with full oil and full load, its operational radius can reach 2200km.

At ultra-low altitude, the operational radius is 1364 km.

Of course, according to different missions, the quantity of ammunition and fuel can be slightly increased or decreased. After all, when the internal fuel of fbc-1a fighter bomber is fully loaded, it can reach 6.2 tons.

Reducing 1.5 tons of fuel and adding it to the weapon load to reach a full load of 12 tons is just a kind of mounted sample of combat mode.
