The American F-22 fighter jet claims that its maximum cruise speed without afterburner is up to Mach 1.72. This is mainly due to its excellent low-drag aerodynamic shape, built-in weapons, and high-thrust F119 engine. This is also one of the signs of the "generation gap" between the aircraft and the third-generation fighter.

The aerodynamic design of the J-30 fighter is more excellent, more advanced, and the maximum cruising speed without afterburner is as high as Mach 2.3, and if the afterburner is fully opened, the maximum speed can reach a terrifying Mach 3.5, and the F22 fighter can be thrown far away at once, and the F22 only eats ashes.

The excellent supersonic cruise performance of the J-30 fighter gives it the ability to quickly engage the enemy, quickly occupy a position, greatly increase the missile attack area, quickly leave the battlefield, and get rid of the attack.

In the future, on the battlefield, if the J-30 fighter does not want to entangle with the opponent and accelerates its separation, then the opponent will not be able to catch up with the J-30 fighter with super-patrol capability anyway. To put it simply, if the J-30 fighter runs out of medium-range bombs and turns around and runs, the opponent will not be able to catch up or reach it. So a good super-patrol is very safe even if it is used to escape.

After listening to Li Tianfeng's introduction to the performance of the J-30 fighter on the supercruise, Minister Ma was greatly surprised, in the past, Minister Ma's understanding of the J-30 fighter super-patrol was far from being so comprehensive and in-depth, but this time it is different, it can be regarded as a more comprehensive understanding.

As the minister of the general armament and a senior general of the military, he should not have written the surprise on his face, but at this moment, Minister Ma was very happy and did not hide it at all.

Minister Ma said: "Mr. Li, this super patrol is good, I didn't expect our J-30 fighter to be so fast." ”

As a heavy twin-engine air fighter, the J-30 fighter not only has a large bomb load but also has good stealth capabilities. And it has ultra-long range and excellent supersonic cruise capability.

Zhang Haiping used to have frequent technical exchanges with Li Tianfeng, and his understanding of the J-30 fighter can be described as relatively in-depth and comprehensive.

Zhang Haiping said with a smile: "Minister Ma, our J-30 fighter is not only fast, but also has excellent maneuverability. The full-motion small vertical tail synchronous deflection is a unique skill, coupled with the world's best three-dimensional vector thrust control capability of the turbofan 25B engine, which is even more incredible. ”

Minister Ma was interested. immediately asked: "Minister Zhang, why is it 'amazing', talk to me about it." ”

Zhang Haiping looked at Li Tianfeng, Li Tianfeng smiled and said, "It's okay, Minister Zhang, it's better for you to introduce it." ”

"Then I won't refuse." Zhang Haiping said: "Compared with the F22 or the Russian T50 fighter, our J-30 fighter has higher flexibility and large elevation capabilities. The J-30's full-motion vertical tail design provides sufficient heading steering torque to provide a large roll rate. The J-30 fighter also has better acceleration and climb rate. ”

Immediately, he said: "I didn't expect that our J-30 fighter has such excellent maneuverability." This is the legendary dual realization of 'super patrol' and 'super maneuver'! ”

Zhang Haiping said: "That's not all. The excellent stealth performance of the J-30 fighter, when fighting in the air, it is completely impossible for the radar of the third-generation fighter to detect our J-30 fighter, even if it is a fourth-generation fighter, such as the F22 fighter, our J-30 fighter must enter a range of 10 to 20 kilometers from the F22 fighter, and the other party may find our J-30 fighter. ”

Within 10 to 20 kilometers, the F22 fighter is likely to be detected. And it's just a possibility, if the other side really wants to find the J-30 fighter. I'm afraid that I have to wait for the J-30 fighter to enter within 10 kilometers of the opponent.

What is the concept of entering a range of 10 kilometers at high altitude, at a distance where the pilot can almost see each other with his eyes.

With such excellent stealth performance, this means that the J-30 fighter can be used in over-the-horizon combat. With advanced radar, the J-30 fighter can strike the enemy first.

Immediately Jiang looked happy, and said with a smile: "This is better, I like it first." ”

The three of them were in Li Tianfeng's office, drinking tea. Chatting about the J-30 fighter, with the more and more in-depth understanding of the J-30 fighter, Minister Ma laughed from time to time and was very happy.

………

In the aircraft R&D center, in a lounge, two experts are also chatting, everyone reviewed a large number of design drawings and design materials, took time to rest, chat, drink tea, and smoke.

The topic of everyone's chat is naturally about the J-30 fighter, these two experts, one is an expert of the jury, and the other is an expert of Tianfeng Technology Company.

Zheng Xuezhu is a design expert of Tianfeng Technology Co., Ltd., an expert in the design of aircraft structural strength, and Liu Yiwen is a review expert and a design expert in structural strength.

Liu Yiwen and Zheng Xuezhu knew each other many years ago, because both of them are the top structural strength design experts in China, but Zheng Xuezhu jumped ship to join Tianfeng Technology Company more than a year ago and became one of the design experts of Tianfeng Technology Company, while Liu Yiwen is still in the original unit.

Liu Yiwen said: "Lao Zheng, the structural design of the J-30 fighter is very advanced and very scientific. ”

Zheng Xuezhu smiled and said: "Lao Liu, you don't think that the structural design of the J-30 fighter was completed by me." ”

Liu Yiwen said suspiciously: "Isn't it?" As far as I know, Tianfeng Technology Company's aircraft structural strength design expert is only you, Lao Zheng. ”

Zheng Xuezhu said with a smile: "It's not a secret, the structural design of the J-30 can be so advanced and so good, I don't dare to take credit, because at the beginning of the design, Mr. Li personally drew a structural strength design sketch for us, and the sketch even marked the main dimensions and technical requirements, we only need to carry out the specific design according to the sketch." ”

Liu Yiwen pointed to the sky, and then said with a look of disbelief: "Lao Zheng, you mean Li Tianfeng, no!" ”

Zheng Xuezhu said: "Lao Liu, don't believe it, although our Mr. Li is only in his early thirties, but the technical level is not beyond the reach of you and me, the design of the entire J-30 fighter is basically completed under the guidance of Mr. Li, not only the structural strength design." ”

"Ahh

This time completely subverted Liu Yiwen's understanding of Li Tianfeng, and after a long time, Liu Yiwen said: "I can't imagine it, if it weren't for what you Lao Zheng said, I would never have believed it." ”

Zheng Xuezhu said: "Lao Liu, if you don't listen to me, join our company, let's work hard, in our lifetime, develop a few excellent aircraft, no longer leave regrets in this life, how about it?" ”

Whether it is Zheng Xuezhu or Liu Yiwen, they are both college students in the 80s, and that generation of college students are full of enthusiasm and want to contribute to the motherland's aviation industry and make their own contributions.

Hearing this, Liu Yiwen was very moved, but remembering that he was more than fifty years old, his hair was gray, and he was going to retire in a few years, Liu Yiwen said: "Lao Zheng, I am in my fifties, I still stay in the original unit for a few more years, and then retire smoothly." ”

Zheng Xuezhu said: "Lao Liu, there are still a few years, aren't you ready to work hard?" ”

Liu Yiwen sighed softly and said: "Let's talk about this matter, if I want to come, then Lao Zheng, you can help me and recommend it." ”

Zheng Xuezhu said: "Lao Liu, you are one of the top structural design experts in China, as long as you want to come, I believe that we will always welcome you." ”

Zheng Xuezhu knew that Li Tianfeng attaches great importance to talents, and the treatment of technical talents is good, and the status is also very high, so Zheng Xuezhu said so.

Liu Yiwen changed his words, and then said: "Lao Zheng, if you think about it, I will contact you again, let's go, let's take a look at the structural design of the J-30 fighter." ”

Zheng Xuezhu got up and said, "No problem!" ”

………

The design acceptance and review of the J-30 fighter has been carried out for several days, the first three days of the main experts reviewed the design data and design drawings, three days later, one by one the size of the review meeting began to be held, and the last day, it was held the acceptance and review meeting.

This conference, not only Minister Ma, Zhang Haiping, Li Tianfeng, etc., as well as all the acceptance and review experts all participated, Tianfeng Technology Company's middle and senior personnel, technical backbone, etc. also participated, very huge, the meeting lasted a whole day.

At the conference, many experts spoke, and everyone's opinions were basically the same, basically praise the J-30 fighter, and there were some opinions raised, but basically they were some suggestions or some minor problems.

The design acceptance and review of the J-30 fighter basically passed smoothly, and finally, Minister Ma spoke on behalf of the military.

Minister Ma highly praised the J-30 fighter, and it can be seen from Minister Ma's expression that Minister Ma was very happy.

The J-30 fighter is so good, through the design acceptance and review in the past few days, Minister Ma has a more in-depth and comprehensive understanding of the J-30 fighter, and Minister Ma's speech is even more stingy with praise.

Even, Minister Ma said that if the Jian-30 fighters are equipped with troops in large quantities, the strength of China's air force will be greatly improved, and it will bring qualitative changes to China's air force.

Bring about a qualitative change!

Hearing this, Li Tianfeng was slightly excited, and did not think that the military's evaluation of the J-30 fighter was so high, that it could bring about qualitative changes.

The senior executives of Tianfeng Technology Company who attended the meeting, their faces were slightly red, and they quietly glanced at each other, and their eyes were full of excitement and joy, as well as a strong sense of pride and achievement.

A few days of design acceptance and review was officially passed, and soon, Tianfeng Technology Company got the design certificate of the J-30 fighter, and then the trial production of the J-30 fighter was in full swing.
