Chapter five hundred and ninetieth ramjet
Chen Yijian is already sixty years old and has a head full of white hair. However, his motivation is very strong at this time.∈◆,
Thinking back to the beginning, for the sake of the JH-7 project, I had to apply for some funds from my superiors, especially after the Air Force gave up, the development of the JH-7 was even more difficult.
Now, even without relying on funding from superiors, Xifei can develop new projects! This is the power of the market economy!
Everyone in the factory was full of energy.
All of this, to a large extent, must be thanked for Pakistan's help and for Pakistani President Mhamad. After all, this road was pointed out by Mhamad that it was through the export of Spey engines that it flew west through that most difficult period.
Now, when we learned that President Mhamad was here to inspect, Xifei held a grand welcome ceremony, and the company's employees all went to the airport to welcome him.
When Mhamad got off the plane, he thought the factory had deliberately mobilized so many people to welcome him. Only then did he realize that it was all spontaneously these employees.
The weather was not very good, and it was raining lightly. Minister of Defense General Qin, Air Force Commander-in-Chief Wang Hai and others accompanied President Mhamad and walked into the West Flight in the drizzle.
"President Mhamad, welcome to visit us." Chen Yijian said with an excited voice.
"Mr. Chen, your side has been able to imitate the Tomcat fighter jet?" Mhamad asked directly.
When Chen Yijian heard Mhamad's question, he felt a little embarrassed: "Yes, we basically copied it ourselves, the wing box part, which we cannot make. Moreover, the few of the ones made were exported."
When exporting these aircraft, Chen Yijian felt that it was a bit inappropriate when he did not notify Pakistan. In fact, they planned to notify them, but before he could tell, Mhamad arrived in Chengfei and knew what happened here.
"Why can't you make the wing box part?" asked Mhamad.
"The wing box is the most important part of variable swept wings. It is made of titanium alloy. Our manufacturing capacity is limited and the processing accuracy is not enough." Chen Yijian said: "We tried to build it several times, but the result was that the strength and accuracy are not enough, and it was not enough to be used."
Mhamad nodded. This wing box is indeed the most difficult to manufacture. Even in Pakistan, advanced titanium alloy technology was introduced and multi-axis linked CNC machine tools were used to process wing box with sufficient accuracy.
When Wang Hai immediately frowned when he heard that some of them could not be produced. It turned out that Xifei could not start manufacturing immediately!
"If you still need it, you can order it from us in Pakistan," said Mhamad. "We ship it to you at the same price as domestic orders."
Chen Yijian suddenly felt happy: "Thank you President Mhamad, with this key component, our output will not be limited."
"Is there any finished product now?" Wang Hai asked.
"There is one that is about to be assembled, right in the factory." Chen Yijian said: "It is the last one to be delivered to Iran."
The factory was clean and tidy. Some technicians were busy working on the assembled plane.
"Is there any difference in performance between this Tomcat fighter and the American-made fighter jet?" Wang Hai asked.
In Chen Yijian's memory, this is the first time in three years that the commander-in-chief of the Air Force came to West Flight. This time, West Flight is about to turn around! Chen Yijian said: "The performance of fighter jets made in the United States is never inferior. In some places, we are better, such as avionics and engines, which are all made by ourselves. They are more advanced than the original avionics and engines."
Americans themselves use the t30, which is difficult to handle. Using the t41 modified by Spey, the performance is much better. Combined with a variety of airborne radars, the airborne pulse Doppler radar developed by China itself is also better than the original AG-9.
"Xiangfei has been self-reliant and has copied first-class fighter jets. This approach should be reported to the entire army for praise." General Qin said affirmatively.
"We will definitely continue to carry forward this style of self-reliance and hard work. Of course, there are also selfless help from our Pakistani friends." Chen Yijian said.
"If the raw materials are sufficient now, how much will the annual output of this Tomcat fighter of West Aircraft be?" Wang Hai asked Chen Yijian.
Is this the Air Force going to place an order? Chen Yijian was even more happy and said, "There will be about ten to twenty aircraft in the early stage, and after becoming more skilled in the later stage, the annual output will be about forty aircraft."
The production of fighter jets is not a car, but the assembly line operation is completed soon. Many assembly is purely manual, such as the skin of the aircraft, which is riveted by workers one by one. Even in Pakistan, the number of Tomcat fighter jets produced in a year is about thirty.
Wang Hai looked at the tomcat with great enthusiasm. When he had made up his mind to equip this fighter, he would feel that this fighter was good everywhere. In the past, the Air Force also regarded variable swept wings as a development direction!
"After going back, we will conduct an argument. The Air Force can first equip this fighter jet to evaluate whether it is suitable for our Air Force." Wang Hai said.
"The powerful interception capability of the Tomcat fighter also comes from the Immortal Missile it carries." Mhamad said: "Using long-range air-to-air missiles to conduct long-range strikes on targets is of great practical value in actual air combat. Now, we cannot just imitate a fuselage, but we should also develop corresponding air-to-air missiles."
Long-range air-to-air missiles are also very important in future wars! Its purpose is to attack the enemy's high-value targets, such as early warning aircraft!
However, if you attack an early warning aircraft, the range of the Immortal Bird's more than 100 kilometers is considered close. The best one is more than 300 kilometers, or 400 kilometers. This kind of air-to-air missile is the ultimate skill of the early warning aircraft.
Long-range air-to-air missiles, besides the Immortals, are Soviet missiles. In fact, the Soviet R-33 missiles have a strong Immortal bloodline.
However, these two missiles use solid rocket engines. The technology of this engine is already a big guy weighing half a ton when it creates the Immortal Bird missile. If you want to have a longer range, you must use new technologies, such as ramjet engines!
Pakistan already has medium-range air-to-air missiles, and there are several short-range air-to-air missiles. Only this long-range air-to-air missile has always been blank. In the past, relying on its relationship with the United States, it bought and bought a batch and made a batch, and most of them were consumed in air battles with the Soviets. Now, the stock of these Immortal missiles is very small, and Pakistan also needs a new long-range air-to-air missile to use!
Since China has decided to equip Tomcat fighter jets, it is impossible not to be uninterested in such long-range air-to-air missiles.
"Do we want to comprehensively map the Immortal Bird missile?" Wang Hai asked: "Or will we modify our Hongqi 9 surface-to-air missiles to fighter jets?"
There is also a precedent for converting surface-to-air missiles to air-to-air missiles. There are very few Iranian Immortal missiles left. Iranian technicians tried to mount the ground-to-air Hawk missiles onto fighter jets, and they were successfully launched! The Immortal missiles are only available in the United States in the world, and the Hawk missiles have long spread to the entire Western camp. The Iranians can easily bring this missile to Iran through smuggling, which has given their Tomcat fighter jets a second spring in their lives.
Mhamad shook his head. The missile of the Red Flag 9, that is, the Shield of Friendship, is too large. Mounting it on the Tomcat fighter will cause the fighter to be extremely bulky, and the software will have to be reset. In fact, the technology of the Immortal Missile is already lagging behind.
"We need to redevelop and create a missile that uses ramjet engines," Mhamad said.
The Immortal Missile missile is huge and has a considerable weight, which makes the Tomcats carrying Immortal are very bulky and cannot adapt to future air combat. In later generations, the meteor missile developed in Europe is a very good inspiration. On the basis of medium-range air-to-air missiles, the engine will be improved, the range will be increased, and more advanced missiles will be developed.
The overload of the Immortal Missile is only about 20g, while the overload of medium-range air-to-air missiles generally exceeds 30g. Moreover, the technology of medium-range air-to-air missiles is more advanced. For example, the Active Sky Flash, which Pakistan now produces, is an air-to-air missile with excellent performance.
"Based on our medium-range air-to-air missiles, improve the engine and significantly increase the range." Mhamad said: "Meet our combat needs in the next twenty years!"
Rocket engines need fuel and oxidants inside, and even if they are not fast-burning, they only burn for a few dozen seconds. The rest are flying inertia in the air. The ramjet engine uses oxygen in the air and only carries fuel. During the entire flight, it is almost always in the power flight stage, with fast speed and good performance.
China has reserves of ramjet engines. Almost after China was established, among the large number of scholars sent to the Soviet Union, there were specialists in learning ramjet engines. At the same time, the sea javelin air missiles equipped by Pakistan used ramjet engines, and the Soviet Sam-6 used solid rockets and ramjet integrated engines.
Mhamad mainly mentions the idea that future long-range air-to-air missiles must use ramjet engines as power!
