Dominate South Asia

A fighter aircraft is composed of multiple components. The performance of each subsystem will affect the performance of the entire aircraft.

For Eastern countries, what they lack most are avionics and engines. Among them, the engine is the most important. It is the Mount Everest of industry. Even thirty years later, the avionics system has been conquered by Eastern countries, but the engine is still a weak point. The Flying Leopard fighter had to use the Spey engine that the British had sealed. The J-10 still had to rely on the Russian AL-31. Although the self-developed turbofan-10 claimed to have met the installation requirements, it was still far more advanced than the AL-31. , but the Air Force just doesn’t buy it and is unwilling to pretend.

Mhammad is not an outsider. He at least has experience in later generations and knows what both sides lack. In later generations, with the continuous advancement of electronic technology in Eastern countries, avionics even began to surpass Russia. However, the engine It's always a weakness.

There are many mistakes and sighs. If we start to change now, it will definitely not be what it will be like in future generations. At the same time, this is also very important for Pakistan, because if Pakistan wants to become a truly powerful country, it needs An independent defense industry requires its own technology.

It's a win-win.

The Eastern countries' Flying Leopards and J-10s all built their own airframes, with only avionics and engines, which have always been a weak point of constraints. It was not until the J-10 introduced the Su-27 and obtained the AL-31 engine that it Start developing rapidly.

"I wonder how we can cooperate?" Turkeda asked Mhamad.

"If you want to have an advanced fighter, you need an advanced engine." Mhamad said: "The Tomcat fighter we are equipped with is very advanced in performance, but the engine is a shortcoming that restricts the Tomcat. We hope Cooperate with your country to jointly develop a new engine.”

Nur-Khan looked at Mhamad with sharp eyes. Although this matter was not reported to him in advance, Nur-Khan did not feel that Mhamad was rude. On the contrary, his heart was filled with joy and excitement. .

Noor Khan is old. The Pakistan Air Force needs fresh blood and energetic people to take the helm. Now, the one Noor Khan is most optimistic about is Mhammad.

Due to Pakistan's economic situation, as a cash-burning air force, although it has received special attention from the president, its equipment has always been lagging behind, so that they had to use the J-6 to fight against the enemy's advanced fighters, although they were defeated several times. Strong, but feeling a little guilty in his heart. As the leader of the Air Force, he did not equip the Air Force with advanced fighters.

All of this has changed significantly in the hands of Mhammad. Mhamad has used various methods to make the Pakistan Air Force have significant changes within a year. Tomcat fighter jets, E- 2 early warning aircraft, as well as electronic jammers, the Pakistan Air Force has suddenly become the air force of a powerful country in South Asia. Noor Khan has secretly regarded Mhamad as his successor.

And now, after hearing Mhamad's words, Nur Khan has strengthened his judgment. Mhamad has been building Pakistan's strong air force. His vision is further, not only equipped with advanced fighter jets , and they also want to cooperate in developing engines!

Nur-Khan also knew that when the country would not pay a penny, Mhammad must have other ways.

At this time, Mhamad just glanced at Nur Khan, as if asking him for instructions. Nur Khan nodded, and Mhammad continued: "As far as I know, your country has introduced British The complete production process of Spey engine has the ability to produce Spey engine.”

Spey engine! After hearing this, Chen Yijian immediately looked at Hamad with extremely firm eyes, his eyes full of passion.

The Spey MK202 engine is a relatively advanced turbofan engine developed by the British Rolls-Royce Company in the mid-1960s. It is 5025 mm long, 1093 mm in diameter, and weighs 1850 kg. It has a maximum thrust of The force is 54.5 kN, the afterburning thrust is 91.1 kN, the thrust-to-weight ratio is 5.05, the maximum military fuel consumption rate is 0.0684 kg/N·h, the maximum afterburning fuel consumption rate is 0.2 kg/N·h, and the bypass ratio is 0.62.

This is a mature engine with eighteen hundred hours of rebuild time. In the early 1970s, the United Kingdom used this type of engine to replace the J59 turbojet engine on the F4K fighter jet imported from the United States. The Spey was also called the Ghost Spey. At the same time, due to its good performance, the United States also introduced the manufacturing rights of this engine and improved it into the TF41, which is used in the A-7 attack aircraft and plans to use it in the Tomcat.

Since Eastern countries did not have a practical turbofan engine for a long time, they began to negotiate with Rolls-Royce in the 1970s. In 1975, they began to sign a contract with Rolls-Royce and confirmed the At the beginning, Shen Aircraft was responsible for the introduction of Spey engines. Later, due to various reasons, it was transferred to XAC.

In the second half of 1979, Xi'an Aviation Engine Factory installed four engines in two batches. After that, a 150-hour long-term test drive assessment was completed. We also went to the UK to complete high-altitude simulation tests, start-up tests at minus 40 degrees Celsius, and cyclic fatigue strength tests of five major components. The test results met the technical requirements. The British side stated that the Sibei manufactured by XAC has reached the original factory's standards and is made of British blanks. The next step is to switch to domestically produced blanks.

Unfortunately, the localization of Spey and the development of the WS-9 engine were abruptly stopped here.

Chen Yiqian knew the inside story. Xi'an Aircraft Corporation was under tremendous pressure. This pressure came from the important project that Xi'an Aircraft Corporation was currently undertaking, the JH-7.

The H-5 and H-6 were too slow, and the supersonic Q-5 had a short range and a small payload. Therefore, the Air Force was eager for long-range fighter-bombers, and the Navy also needed long-range anti-ship attack aircraft. The JH-7 was approved under this premise.

However, since the approval of the project, the Navy and the Air Force have been in a quarrel. As a fighter-bomber, two flight crews are required. The Air Force hopes that the cockpit will adopt a parallel layout, while the Navy hopes that the cockpit will adopt a tandem layout. In the end, for various reasons, the 603 Institute decided to develop a tandem double-seat first, which offended the Air Force, and the Air Force has since ignored the JH-7.

As a result, the JH-7 became a project of the Navy, and the Navy's defense budget was not much to begin with. Now that the economy is being adjusted, the JH-7 has received very little funding. As the supporting engine of the JH-7, the Spey has no money to continue the localization. Anyway, there are 50 original engines in stock. The country has cancelled the Spey project and paid a large sum of money to Rolls-Royce.

The project of the 603 Institute is struggling. This time, he came out and saw Pakistan's advanced fighter jets. Any subsystem requires a lot of money to build. He is full of interest and is also worried about the project he is in charge of. In front of advanced fighter jets, the JH-7 is nothing.

(Writing this, Huadong Zhixiong is very sad. He took so many detours and wasted so many good opportunities. There were institutional problems, short-sighted decision-makers, and... In short, I pay tribute to the scientific and technological workers who persisted in working in adversity and finally developed various fighters such as the Flying Leopard and the J-10! It is you who support the sky of the Republic!)

Hearing Muhammad talking about Spey, Chen Yiqian immediately became energetic: "Yes, now, our localization has reached 86%. As long as there is more capital investment, the localized Spey engine can definitely be developed."

"Then, I don't know if you know that there is actually an increased thrust type of Spey." Muhammad continued: "The Spey is only a medium thrust, but it can be improved to become a high thrust engine. The installation range is wider, and single-engine light fighters and twin-engine heavy fighters can be equipped. For example, it is very suitable to equip our Tomcat fighter."

Isn't this TF41? Chen Yiqian thought in his mind that since the Spey was domestically produced by Xi'an Aircraft Industry Corporation, Xi'an Aircraft Industry Corporation was more familiar with this engine and naturally knew that Rolls-Royce had such a modified engine and successfully exported it to the United States and installed on the A-7 attack aircraft.

However, although it is a thrust-enhanced model, the core has not been changed, but the changes are not small. It uses a brand-new fan and low-pressure compressor, and the original 5-stage fan is changed to a 3-stage fan and a 2-stage low-pressure compressor. The fan diameter is increased from 826mm to 950mm, which increases the air flow and pressure ratio. The inlet guide vane is cancelled, the high-pressure compressor is changed from 12 stages to 11 stages, and the installation angle of the turbine guide vane and the rotor blade is modified. Through these modifications, the engine thrust is increased by 17%. Now, the basic model has not been developed in China, so how can we develop a thrust-enhanced model?

However, if it can be developed, Chengfei's new model may also be used, and the heart problem of domestic fighters can be overcome.

But where does the technology come from? Where does the money come from? Now the Spey has almost come to a halt, and the JH-7 project is also facing the risk of abortion. The Navy's funding is not enough.

"Yes." Chen Yijian said, "I know there is such a model."

"If you are interested, we are willing to cooperate with you to develop such a high-thrust engine. We can provide some technology and a physical engine for mapping." Muhammad said, "I believe that with the joint cooperation of technicians from our two countries, this engine can be fully developed."

Pakistan provides technology? Physical engine? Why don't I know? When did Pakistan have engine technology? When did it have a thrust-enhanced Spey engine? They don't even have a basic model, right? And how to solve the funding problem? Pakistan's advanced fighters are now almost all borrowed.

Then, Muhammad continued to say the next sentence, which immediately made Chen Yijian suddenly enlightened.
