Seeing that the head of the headquarters looked blank, Zhuang Jianye didn't know about the two combat modes of the fc-1a fighter-bomber. The Northwest Aviation Plant has not reported it.

But regardless of whether the two combat modes are too monotonous, Zhuang Jianye doesn’t care if he wants to gather a few more to make the report look better; or if he wants to give his superiors a big surprise and have some thrilling little surprises. On it.

Didn’t look at the 10,000-character review by the head of the headquarters? If you don’t highlight your own skills, let alone the funding and policies of laser products, look at the head of the headquarters. Can the 10,000-character review be possible? It is unknown if it can be blocked.

So Zhuang Jianye put the Northwest Aviation Plant aside without saying anything, and nodded dogmatically at the frowning head of the headquarters: "Yes, the chief is attacking the Leopard, because compared to the previously submitted fc-1a fighter-bomber. The basic shape, the attack leopard is replaced with a wd-62suv medium-thrust turbofan engine that is better than wd-62sm. The thrust-to-weight ratio has been increased from 6.5 of the original wd-62sm to 8 of wd-62suv, making the engine cruise thrust reached 5.8 Tons, the normal maximum thrust is 6.5 tons, and the afterburner thrust reaches 8.8 tons."

After a series of indicators were uttered from Zhuang Jianye's mouth, the head of the headquarters couldn't help being surprised. As long as the leaders of other units knew a little about aero engines, they were all incredulous.

Some leaders even rushed to the rear of the fuselage altogether, and even leaned on the air inlet to look directly in.

No way, these leaders really want to see what this medium-thrust aero engine with a thrust-to-weight ratio of 8 is like.

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

Because the afterburner thrust of wd-62sm is 9 tons, don’t look at this value than the 8.8-ton afterburner thrust of wd-62suv, but it cannot be said that wd-62sm is stronger than wd-62suv, after all, wd-62sm The thrust-to-weight ratio is only 6.5, and the weight of the whole machine reaches 1385 kg.

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

It is heavier than a precision strike weapon outside the gsn-500 joint defense zone.

In other words, the energy density of the wd-62suv engine is greater, and the unit thrust is stronger. Even if the afterburner thrust is 0.2 tons less than the wd-62sm, the two are basically the same in terms of comprehensive weight reduction and unit efficiency. Not at the same level.

What's more, in addition to afterburner thrust, ordinary maximum thrust and cruise thrust wd-62suv are much higher than wd-62sm. As for the original Spey mk202 turbofan engine of the fc-1 fighter-bomber, it is even more incomparable. .

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

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

The engine alone can reduce the weight of the fc-1a fighter-bomber by 1.5 tons compared to the old model, which is no different from the external hanger for the aircraft.

This is indeed the case.

The fc-1a fighter-bomber adopts the original version of the wd-62sm aero engine. The indicator is capable of carrying 8 tons of ammunition. When performing a high-altitude attack profile, the combat radius is 1,860 kilometers.

When performing a low, low, and full ultra-low altitude attack profile, the combat radius is 1,187 kilometers.

Don't underestimate the 8 tons of ammunition. The domestic H-6 bomber has a maximum load of 9 tons. That is the existence of the so-called bomber.

The Su-30mkk fighter-bomber imported from Russia has a maximum payload of only 8 tons.

Therefore, when the original version of the fc-1a fighter-bomber using the wd-62sm aero engine was reported, both the headquarters and the navy and air force were very satisfied with the prototype's specifications.

It is believed that there is one more fighter-bomber capable of carrying 8 tons of bombs and an average combat radius of 1,500 kilometers, capable of performing a variety of ground attack missions, and capable of fully autonomous and controllable fighter-bombers, and is capable of building the navy, air force, and aviation capabilities and performing multiple tasks Ability plays a pivotal role.

What I didn't expect was that the original wd-62sm engine turned into a wd-62suv aero engine. The maximum bomb load of 8 tons has increased to 12 tons.

It also formed the so-called prototype and attack leopard two models.

To be honest, if it were not for seeing it with his own eyes and hearing with his own ears, it would be difficult for the head of the headquarters to believe that all this is true.

Not to mention the head of the headquarters, even Zhuang Jianye did not expect to set up a prototype version of the project, but it came out to attack the Leopard, there is no way, it is not that they really want to give their superiors a big surprise, but the second-generation core machine high-end version of Ascendas Group The 11 MW core engine made a breakthrough, and the new generation of medium thrust engines developed on this basis immediately became a new benchmark.

In contrast, the wd-62sm, which uses the second-generation low-profile version of the 6-megawatt core machine, is actually just an improved version of the Spey mk202.

Fans, compressors, and even afterburners are all imitated from Spey mk202, but the combustion chamber and high and low pressure turbine adopt the 6 MW core engine of Ascendas Group, which increases the temperature in front of the turbine, which is no less than Spey. While the original thrust of mk202, the quality of the whole machine has been greatly reduced.

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

It is also because of this that the main wd-62sm production plant is located in the engine production plant under the Northwest Aviation Plant. Ascendas Group does not have large-scale production, but is responsible for the manufacture of the supporting 6 MW core aircraft. At best, it is only important for wd-62sm. No more spare parts suppliers.

In contrast, the wd-62suv aero engine is different.

This is the core military engine currently used by Ascendas Group. It is the main power of many military combat aircraft developed by Ascendas Group, including JJ-7max, JZ-119, Zhenlong, etc.~lightnovelpub.net~ even in the third generation core. When the aircraft matures, part of the third-generation core aircraft technology will be transplanted to the wd-62suv aero engine, striving to increase the thrust-to-weight ratio to 9, or even 11, so as to lay the foundation for the power of the next generation of medium-sized combat aircraft.

Therefore, wd-62suv can be said to be the son of Ascendas Group.

Now that his own son has been born, wd-62sm, which was adopted to others, should be given way.

Although Northwest Aviation Plant expressed disagreement with the idea of ​​Ascendas Group, after all, changing aircraft engines for combat aircraft is not about changing wheels on toy cars. It requires a lot of engineering rationalization calculations.

Thanks to the early preparations of Ascendas Group, the size and size of the engine are not much different from the wd-62sm, and it can be installed on the fc-1a fighter-bomber smoothly without any major changes to the aircraft.

Then...then Northwest Aviation Plant was captured again by the law of truth.

The fc-1a fighter-bomber that was replaced with wd-62suv was immediately improved. Not only did the bomb load increase from 8 tons to 9.5 tons, thanks to the excellent fuel consumption control of wd-62suv, the range was also increased compared to the original model. By 32%.

Because of this, the attacking leopard has a combat radius of up to 2,200 kilometers when performing a full-fuel, high-altitude, high-altitude long-range profile attack mission.

During the entire ultra-low altitude, the combat radius is 1364 kilometers.

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

Cut 1.5 tons of fuel and add it to the weapon load to reach a full load of 12 tons, which is completely a model of combat mode.
