"Is our model OK?" As the American left, the man sitting in the chair in the back, Aerospace Industries technician Amod from Pakistan asked Hills, an engineer beside him.≧,

They come from Pakistan Aviation Industry Corporation. Now, Pakistan's aviation industry has just started. In the past, it was just a J-6 major repair factory. Now, being able to repair 100 engines, the Tomcat fighter jets and A-7 fighter jets is their limit. Although they are also working with other countries, such as developing Gripen with Swedish technicians, developing carvings with South African personnel, and developing new fighter jets with Chinese personnel, more are in the stage of observation and learning. Pakistan's own aviation industry is currently unable to take on the heavy responsibility of designing an aircraft.

At this time, the Pakistan Aviation Industry brought a model that was not noticeable at the Famburg Roh Air Show. This model was not really studied by them, but was made by President Mhamad at the instruction of them.

President Mhamad completely explained the advantages of this model, giving them the illusion that President Mhamad is an experienced aircraft designer and is very pioneering. Many of the statements they have never heard of. Now, with this model, they want to bring their own design to the whole world. For the time being, no one seems to be interested.

After a long time, no one came here except for a reporter who came here to take a photo.

It seems that this time I will return without success.

The whole morning passed like this. When I was eating the lunch I brought with me calmly next to the exhibition stand, suddenly, a large group of people gathered around.

These people are all Americans, and there is a burning flame in their eyes. Looking at the model on their side is like seeing a lover.

"How did your model come from?" The leading man, who is already over fifty years old, should be a senior technician. There was a hint of trembling in his words and his words were not smooth.

Well, someone finally took the bait! Looking at these Americans coming, Hills said: "This is what we designed ourselves."

Designed by yourself? The American opposite said, "How did you design this kind of aircraft? What is its design idea?"

"Stealing performance. Now, radar has become an important means of detecting aircraft. Our fighter jet is to stealth in front of the radar, so that the opponent cannot detect us. We expect that our own stealth method can make the radar reflection area of ​​a bomber as big as a B-52. "Shiels continued.

The other party opened his eyes wide, as if he didn't believe what Hills said.

"How did you do it?" the other party asked.

"We have our own special electromagnetic laboratory. In the laboratory, we design various shapes to detect the reflection of radar waves. Aircraft like us. No matter where the other party's radar wave comes from, it can always be reflected in other directions and cannot return to the original radar receiver. In addition to reflection, it is more important to absorb. We have developed a special coating, which can absorb micro-segment radar waves. Reflection and absorption can greatly reduce the probability of being discovered by radar and improve our stealth performance. We also use computer-aided design to help us determine a more suitable shape."

Stealth performance! In this era, stealth is still a technical standard set by the US side for subsequent combat mechanisms. It has not been promoted and has no market in the world. Most aircraft designers believe that this is something that is only available in science fiction novels.

Only the United States, knows the impact of stealth performance on future air combat, spares no effort to develop various stealth aircraft. Now, the first stealth attack aircraft, the -117, has entered service in the United States.

Americans began to study these technologies in the 1970s. In the early 1980s, the first product of stealth, -117 was set up in the skunk factory of Lockheed and equipped with the US Air Force. It has been in a state of extreme confidentiality. It does not even fly during the day. Every flight is at night. Even pilot training is carried out at night, with the highest level of confidentiality. It was not until 1988 that the United States released the photos of -117.

Now, except for the United States, no one in the world knows the existence of stealth aircraft, and no one can design stealth aircraft. They can't get rid of their inherent image in their minds.

Now, Pakistani technicians have actually built a stealth aircraft model. Moreover, the model of this stealth aircraft is very similar to Northrop's advanced tactical bomber, the later B-2, and even more perfect than their aircraft!

This kind of aircraft from Northrop has been designed for ten years. It was originally designed with a flying wing layout, but it had a vertical tail. It was not until later that it was improved to have no vertical tail, which could further reduce the radar reflection area.

At the beginning, the tail of the flying wing was a pointed triangle, which later became a shape, which was the result of multiple calculations.

Now, the other party's model is a large flying wing with a shaped structure at the tail, with the crew compartment, equipment compartment, and the engine's intake duct above.

After seeing the other party's model, how can we not interest American technicians? The people who came this time were the team led by Fred, the vice president of Northrop. He came here mainly to promote the company's -20 fighter jets to the world. This fighter jet was developed by the company's own funds. It was originally planned to replace the -5 fighter jets, but unfortunately, I was disappointed and no country was willing to equip it.

Unexpectedly, I saw such a fighter here, which coincided with the stealth aircraft developed by our side!

Was it plagiarized by the other party? It is absolutely impossible! The fighter jet developed by Northrop is the most confidential project. For this project, Northrop bought an idle factory at Ford Motor Company in Bicollifora, a suburb of Los Angeles, specifically used to develop this stealth bomber. This factory has no window and the base is under 24-hour surveillance by the army and security personnel. These protection measures to prevent leakage alone cost $2 billion. The computer rooms here are surrounded by metal plates to prevent electromagnetic radiation. Workers in key positions even have to undergo a polygraph test.

Take Fred himself as an example. A few years ago, before he was approved to participate in the fighter plan, his Canadian wife actually needed to change her nationality and become a U.S. citizen. Even in Congress, only eight members of Congress knew about this.

This kind of aircraft is absolutely impossible to leak. After years of development and exploration, Northrop finally determined its current appearance, which is the same as the shape of the stealth aircraft in front of him. How could this not surprise Fred?

This should be independently researched by the other party, establishing an electromagnetic laboratory, designing this type of aircraft, applying stealth coatings, and using electronic computer-aided design. These are all processes carried out by Northrop.

I really didn't expect that Pakistan's aviation industry would develop so fast! Although they are still behind in many aspects, such as the most important engines, they cannot produce their own products, but if they spend a lot of effort on a certain aspect, it is still possible to make breakthroughs, such as the current stealth design! Now that no other country attaches importance to stealth performance, they have made such progress!

Fred also felt a sense of loss. Now, his stealth bomber is still a confidential project. After many years, the project will be declassified. From the outside world, he thought that his company was copying Pakistani designs. After all, the appearance was announced first.

"Then how do you solve the control problem of the aircraft, such as how to turn without a vertical tail?" Fred continued to ask.

"Behind us, we each designed four-piece speed reduction plate rudders. The two pieces are stacked together, with a rotating shaft in front, which can be expanded up and down. When all the left side are expanded, it is equivalent to the left rudder, and so on. When only the lower part is expanded, it is pressed for the operating lever." Hills said: "It is necessary to use telex operation to control it, and the maneuverability will not be very high. Our fighter is just a bomber. At the same time, we have another solution to improve our Tomcat fighter and give the Tomcat fighter a powerful stealth performance."

What Hills said was a problem that has troubled Northrop for a long time. Without the tail wing, how to control the steering of the fighter jet? When Fred joined the team, he proposed the rudder of the speed reducer. Now, the other party actually said it easily!

They obviously have considered all the issues properly, but because Pakistan's technology is limited, they can only stay on the design drawings at most, and it is not easy to actually make them!

"Can you share your designs with us?" Fred said: "I am Fred, vice president of Northrop. I am very interested in your designs."
Chapter completed!
