Dominate South Asia

If you are a military fan from later generations, you can recognize it almost at a glance, J-20, black silk!

This aircraft model is a fighter jet that Mhammad used his own memory to let the Pakistan Aviation Industry Corporation build. Although it is just a model, all aspects of the design of this fighter jet reflect the most advanced concepts. ! There is nothing better than using the technology of later generations to fool current people.

For example, this bulging air intake is a technology that was only started to be applied on the F-35 in later generations, the DSI air intake!

The full name of this type of air inlet is called a three-dimensional bulging-type no-boundary layer partition air inlet. It uses a fixed bulge to simulate the first and second-level adjustable inclined plates in the conventional air inlet, and can achieve the control of air flow. Compression can simplify the structure and achieve the purpose of invisibility. Compared with conventional inlets, this kind of DSI inlet has three main advantages: first, it adopts a "conical flow" waveriding design, which results in higher total pressure recovery; second, it reduces the resistance on the windward side of the aircraft, It improves the stealth performance of the aircraft; thirdly, without designing auxiliary intake valves and exhaust valves, and eliminating the boundary layer barrier, the aircraft can lose hundreds of kilograms of weight. The reduced weight improves the performance of the aircraft. It has a simple structure, light weight, low resistance, invisible, and can adapt to a wide range of speeds.

However, no engineer has thought of this kind of air intake now. This kind of air intake was first studied by Lockheed Martin in the 1990s. After more than ten years of development, it has finally matured. The three-dimensional surface bulge in front of the air inlet is used to pre-compress the intake air and at the same time increase the pressure distribution to "push" the boundary layer air away from the inlet. There are no moving parts, no boundary layer isolation panels, and no bleed system or bypass system, which is a shame for an advanced air intake method. Even the F-22 was not used, and it was only started to be used by the F-35.

At this time, Pakistan displayed this kind of air intake, which of course surprised all the experts.

In fact, the design of this bulge is also very particular. Its surface area will greatly affect the efficiency of air intake. The air intake in Pakistan simply adds a bulge, and the appearance is not particularly optimized. Even so, it was shocking enough, and it instantly conquered these aircraft designers.

In the blink of an eye, Pakistan has transformed from a backward industrial country into a country that can independently develop advanced fighter jets! Although there are still deficiencies in some aspects, some technologies are excellent, even surpassing those of the United States!

Old Arslan, naturally played a hard-to-get trick, this thing. It was used to fool Americans, and now, Americans have been fooled!

"I'm sorry. Everyone, please come with me." Old Arslan did not answer their questions at all and led them away from here.

Everyone's eyes were full of admiration for the airplane model. Before leaving, they almost kept turning their heads, looking at the design of the airplane, the more they looked at it. The more they feel that the design of every place is so perfect, many problems they did not expect have been easily solved on this aircraft!

The rest of the visit became boring. After it got dark, they ate at the restaurant here.

Looking at the old Arslan who entertained everyone warmly, everyone was thinking about the airplane model in their hearts. However, every time he brought up the topic, old Arslan would give him a thumbs-down and lead him to another topic.

After eating, old Arslan arranged for them to stay in the guest house. His residence was next to them.

An hour later. There was a knock on the door outside.

"Who?" asked old Arslan.

"Me," Paul's voice came from outside.

"Come in." Old Arslan's assistant opened the door. Outside was not only Paul, but also several visiting heads of aircraft companies.

"Everyone, it's so late, what's wrong?" Old Arslan asked.

Sitting on the sofa, Paul spoke first: "Mr. Chief of Staff, today, we saw the aircraft model you are testing. We feel it is very advanced and we are very interested in it."

"That's what we designed for fun." Old Arslan said: "Is there anything else? Alas, people are old and sleepy now."

"No, please don't hide it from us anymore." John from Grumman said: "Your design is very advanced. We have done some research on the bulge in the air inlet. If the design is suitable, it can be used. The function of the adjustable air inlet also simplifies the design, which is simply a great initiative! The shape of your machine head can be maintained relatively smoothly. High aerodynamic performance can also ensure stealth performance. You are indeed at the forefront of technology in this regard. At the same time, you should also know that developing a fighter jet is very difficult. You can do it alone. You cannot successfully develop a cross-generation fighter on your own. Don’t you want to share technology and cooperate with us?”

When you have enough strength, you will win the opportunity to be on an equal footing with the other side. Now, the research results suddenly displayed by Pakistan's aviation industry have surprised even the US military aircraft manufacturers, and they have proposed sharing technology with Pakistan.

Old Arslan looked at the people in front of him. These are representatives of America's cutting-edge technology. There was a trace of helplessness in old Arslan's eyes: "We are very worried about your credibility when sharing technology with you."

Reputation? This is simply an insult to the United States. Paul said: "We in the United States value credibility the most, and our cooperation with Pakistan has always been based on credibility."

"Really?" Old Arslan said: "Then our matter about the F110 engine production line has been delayed for five months, and you have been perfunctory. What's going on?"

F110! The most advanced military engine of the U.S. Air Force! At that time, in order to obtain the Soviet Union's most advanced Su-27 fighter jet and the pilot, the United States reached an agreement with Pakistan to help Pakistan transform the F-14 Tomcat and replace Pakistan's original engine with an F110 engine.

The replacement of the first dozen or so aircraft was relatively smooth. However, when it was discovered that Pakistan actually used F110 engines to allow F-14 Tomcat fighters to take off from the modified aircraft carrier, the United States immediately changed its attitude.

The subsequent F110 engines have not been supplied in time. At the same time, the agreement reached with the United States to introduce production lines has all come to nothing.

The United States did not tear up the agreement, but just shied away from it with various reasons. Pakistan urged it several times, but without any results.

Of course, another reason is that the United States has learned all the details about the Su-27, and the Soviet Union began to promote the Su-27 to the international market. The United States felt that the exchange at that time was not worth it.

After all, there is no trace of the powerful F119 engine in later generations. This F110 is the engine with completely stable performance among American military aircraft, and it almost represents the most advanced technology in the United States. This engine technology was completely provided to Pakistan. This was originally Pakistan's wishful thinking. It created a big pie at the time, but now, there is nothing left to eat.

Old Arslan unceremoniously told the story about the F110 engine production line. The Grumman people present could not help but smile. Grumman had mediated this project, and General Dynamics was also willing to export it. , after all, this is a big project that will make General Dynamics a lot of money.

However, the U.S. Air Force disagreed and changed its mind. This most advanced engine can only be used for its own use and cannot be exported. But the previous agreement had been reached, and it could not go back on its word, so the U.S. Air Force pressured General Dynamics to delay the agreement.

Hearing what Old Arslan said, Paul pretended to be surprised: "What's going on? This project has been delayed? When I return to the United States, I must pursue this matter. Anyone who fails to do things should take the blame and resign!"

Paul said it very seriously. In the United States, there are only more than 100 lieutenant generals in total, and the number assigned to the Air Force is no more than 50. However, at the level of lieutenant general, he is already the top leader of a place, such as the US military stationed in Japan. The top leader of the Air Force is a lieutenant general level person.

Old Arslan felt excited. It seems that with this as bait, these Americans will not set up any more obstacles. Of course, we cannot give them all the technology immediately. Besides, Pakistan now has These technologies simply don't exist.

Those phased array radar rooms are just for show, and many of those walls are fake. Such a machine was built in a hurry half a month ago, including the bulge in the air intake, which was also made under the instruction of President Hamad. A lot of theories can be put forward, but to truly achieve In the application stage, there is still a long way to go.

Now, even if the Americans are completely deceived, the Americans will not feel deceived because of this. During this period of time, we will improve these theories. Of course, we will not be able to achieve correct results in a short period of time. However, when the United States After people get it, they can only think that their own experiments are not perfect. Anyway, these are all experimental results. As for the many theoretical formulas, let the Americans do it themselves. Using this model in exchange for a complete production line, Pakistan can produce this kind of engine on its own, and Pakistan's most important goal will be achieved.

"Yes, we at Grumman will do our best to implement this engine project as soon as possible." John also said: "However, can these technologies from your company be exported to our Grumman? "

Everyone is selfish. If Grumman obtains these stealth technologies, maybe Grumman can win in the U.S. fourth-generation aircraft project. (To be continued ~^~)
