Yes, the aero engine is the foundation and patience, no way, it is really because there is no shortcut to the aero engine.

So this thing can't be in a hurry at all, you can only take it slowly one step at a time, and it is not an exaggeration to describe it as a long march.

Even if there is an external BUFF to help you open the hanging, you may be able to surpass it for a while, but you can't go long, and in the end, you have to turn around and brush up the basic experience a little bit before you can move forward.

Because of this, when the industry is in full swing towards the thrust-to-weight ratio of more than 10 thrust turbofan engines, Tengfei Group did not participate, Zhuang Jianye saw very clearly, with the technical strength of Tengfei Group is not up to the most cutting-edge ceiling.

Instead of earning a few words of good reputation, it is better to arch the existing model forward little by little, accumulate more, and wait for everything to fall into place and explode.

It is with this attitude that Tengfei Group started from the piston engine of the UAV, and silently boiled for ten years, which led to the WD-52ML turbofan engine.

Even if you can't see it in this life, you have to lay a solid foundation for future generations, no way, this is the development status of aero engines, look at the Americans using the old models of the fifties all the way to the present, you should know that there is no shame in silently persevering.

Therefore, Zhuang Jianye is completely dismissive of the industry's criticism of the Tengfei Group's lack of enterprising remarks, and the Tengfei Group's enterprising spirit is not as powerful as those major aviation factories involved in high-thrust engines, but several fingers, which of these large factories can take out a take-off weight of more than 60 tons, a load of more than 20 tons, and can perform more than 5,000 kilometers of transportation tasks of pure domestic jet medium transport aircraft?

No, not a single one.

Some people may say sourly that foreign jet transport planes of the same type use twin engines, but Tengfei Group's uses four engines, and the economy is too poor.

Zhuang Jianye doesn't care, the foreign double engine is good, but no matter how good the domestic air force can't use it, the economy of Tengfei Group's four-engine Zhongyun is worse than that of foreign countries, but whether it is military or civilian, it can be completely let go, no need to look at other people's faces, this kind of transport aircraft freedom can only be known when used, and it is absolutely the same as the relationship between men and women.

At this moment, Zheng Quanli and Wen Kai, who are located on the shooting range island, are particularly able to experience this indescribable sense of freedom, especially watching the Yun\Oil-15 dragging the long refueling pipe for the J-8II behind him.

The reason for this is very simple: the focus of this landing exercise is whether the J-8II can hold out until the Su-27 returns again, and this will play a crucial role in the future deployment of the headquarters on the southeast coast.

If the results of this exercise are obvious, then the in-depth echelon deployment of the headquarters along the coast can be continued, but if there is a discrepancy, the deployment must be adjusted.

Several military regions and hundreds of thousands of troops are not adjusted when it is time to adjust, so Zheng Quanli and Wen Kai are all sweating about the actions in the sky.

Compared with Zheng Quanli and Wen Kai, who just sweated a handful, it was Xue Weidong, the commander of this air exercise, who really put his heart to his throat, and now there are only three fighters in China that can carry out air missions in the far sea.

One is the Su-27 imported from Russia, the other is the "Flying Leopard" of HNA, and the second is the barely filled J-8II.

The "Flying Leopard" is positioned as a missile attack aircraft, and its air combat capability is average, so it can perform combat cruises, and only the Su-27 and J-8II are the ones who can compete for air supremacy.

But the problem is that the Su-27 has a limited number of numbers, and there is no air refueling capability, and its sustained combat capability is limited, so it will have to return to the base after the first round of cruise and air supremacy, and the remaining gaps can only be topped by the J-8II.

It is also thanks to Tengfei Group that delivered two Yun-15 air tankers in a timely manner, otherwise Xue Weidong would not know how to complete the task assigned by his superiors.

At that time, maybe you can only use J-7 on the scalp, or even J-6 on top, as for the effect, only God knows.

It is precisely for this reason that Xue Weidong was very nervous when he was refueling in the air, for fear that something would go wrong and he would mess up the exercise, and it would not matter if he was embarrassed internally, and if he made a fool of himself abroad, he would really have no face to see people; after all, there were quite a few "spectators" in this exercise, and it was the result of the deployment and adjustment of the troops in recent years.

Whether to deter these "audiences" or let these "audiences" watch jokes, to be honest, Xue Weidong is under a lot of pressure.

Fortunately, the performance of Yun\You-15 is also the same as other products of Tengfei Group, stable and excellent, and the in-flight refueling of 6 J-8IIs was completed in a very short period of time, and the return was smooth according to the requirements.

The J-8II, which has been refueled in the air, can maintain a cruising time over the shooting range island for nearly an hour when it is fully fueled, but what should I do if the fuel is not enough after an hour?

When the transport \ oil-15 this nurse is a decoration? fly over and milk again, and it will be over.

Anyway, one hour is enough time for the Su-27 to return to take over, and it is also enough for the transport/oil-15 to run a round trip, not to mention that in order to ensure the smooth operation of this exercise, there is also a transport\oil-15 plane on standby at an airport in the depths of the Yangtze River Delta, which can take off at any time to support.

"Commander, is it time for the next subject?"

Just when Xue Weidong was still immersed in the nervousness of refueling the J-8II for the Y-15 in the air, a sentence from the combat staff officer immediately pulled him back to reality, and he replied with a fixed mind: "Has the target plane been released?"

"Not yet. ”

"Notify the target aircraft that it can be released, and at the same time order each formation to move to the next subject for drills. Xue Weidong issued an order in a deep voice, and the combat staff officer responded decisively: "Yes!"

......

"What is a certain big country in the East going to do?

Half an hour after Xue Weidong issued the order for the next exercise, the "Octopus" soon discovered the traces of the target plane, and in combination with the situation of the six Jian-8IIs hanging on the shooting range island, the next move was self-evident, and a certain large country in the east was preparing to conduct a live-fire target shooting exercise over the shooting range island.

This is also why when the target plane is discovered, Temer will say this, but his words are not affirmative, but a question sentence, and even mixed with surprise and incomprehension that is difficult to hide.

The reason is very simple, the target aircraft used for the live-fire exercise did not fly to about 10 kilometers away from the J-8II formation as he had expected, and it is the best attack position for close-range combat air-to-air missiles.

Instead, it hovered around 50 kilometers and did not advance, which made Temer very surprised, could it be that a certain big country in the East wanted to use the J-8II to practice the strike subjects of medium-range air-to-air missiles?

"Looks like it's going to be a medium-range bullet, you see......"

At this time, Valenrio on the side suddenly spoke, and immediately knocked on the keyboard a few times, and a real-time image transmitted by the reconnaissance plane was presented on the screen, Valenrio stretched out his hand and pointed to a missile under the wing of the J-8II, and said a model with a strange expression: "R-27 medium-range air-to-air missile!"
