Don't look at these people are all wearing the air force uniforms of the national army, but they have blue eyes, yellow hair, big noses, tall people, and speak Soviet dialect. Han Xing immediately judged that these were members of the Soviet Volunteer Army.

The Soviet interpreter was speaking Chinese: "This is Captain Kurishenko of the bomber, this is Lieutenant Gupiko." Why don't you let us in, is there anything else to keep your fighter plane secret? ”

Xu Da's guards were also quite unpolite: "I don't care what high-ranking official you are, I don't care which country you are the leader of, as long as you are not from our base, idlers are not allowed to enter." I only listen to Commander Xu, and I don't listen to anyone else's words. ”

The man named Kurishenko was annoyed, his face flushed, he raised his hands and shouted, and he muttered a word in Russian. The translator translated again: "There is no reason for you to do this!" We, the Soviet people, have contributed so many planes, and they are all the most advanced in the world, what secrets do you have to speak of? Besides, if you can't look at a piece of it, what's not to do. Call your ruler, and I will speak with him. ”

Xu Da's guards became more and more angry: "I repeat, neither can the king of heaven!" I only listen to Commander Xu, and I don't listen to anyone else's words. ”

The two sides were arguing, and Commander Xu came.

The guards reported the situation to Xu Da, who said to the Soviet translator: "I'm sorry, this gentleman. Our airbase is open to no one. If I had to visit, I would have to ask our superiors as well. ”

Kurishenko muttered a few words, and the translator said: "Aren't you a commander, and which commander do you want to ask?" ”

At this time, Xu Da crossed Kurishenko, walked to Han Xing, saluted Han Xing and said, "Commander Han, they have to visit our plane, you say, do you want them to visit?" ”

This drama made Kurishenko watch it inexplicably, and the guards of the plane did not allow him to visit, which was reluctant, but he didn't expect that their commander would not be able to be a family when he came. It turned out that the one in charge was the little young officer next to him.

It seems that, as the Chinese saying goes, burning incense found the wrong temple gate.

Han Xing said to Xu Da: "Commander Xu, it seems that this captain Kurishenko is quite stubborn, if you really don't let him visit, I'm afraid he will have to be in a hurry." Besides, I still have something to discuss with him, so let him visit for a while! Of course, it is only to be seen with the naked eye, not to take pictures or record. ”

Xu Da saluted Han Xing again and said, "Yes!" ”

Xu Da was so respectful to this young little officer, Kurishenko had already seen it, and of course he looked at Han Xing in another way.

Han Xing hurriedly saluted Kurishenko and said: "Hello, dear Captain Kurishenko, I am the commander of the Southern Expeditionary Army, my name is Han Xing. Here, on behalf of all the officers and men of the Yugoslav Expeditionary Army, I would like to extend my warmest welcome and comrade's greetings to our dear comrades-in-arms and comrades, Comrade Kurishenko! ”

Kurishenko also gave Han Xing a return salute, and was about to speak, when suddenly Gupiko rushed forward, hugged Han Xing at once, and shouted: "Commander Han Xing, I finally found you." ”

He came so suddenly that Han Xing was taken aback. Zhang Xiaosan was even more anxious, it was really unexpected for him, he pounced all of a sudden, grabbed Gupico and said, "What are you doing here?" Get up! Get up! If I don't get up, I'm going to be unkind. ”

Wu Xiaoming and Li Dazhong also hurriedly touched their guns.

Han Xing stopped Zhang Xiaosan and said to Gupiko: "Dear comrade, you are looking at the wrong person, I don't know you!" ”

Kurishenko was also surprised: "How come you know, Comrade Gupiko, haven't you heard that there are your friends in the Southern Expeditionary Army?" ”

Not only did Gu Pico not let go, but he also hugged Han Xing tightly, holding Han Xing almost out of breath. Zhang Xiaosan was nervous again, stepped forward to come to Raguppico again, and yelled loudly: "If you don't let go, I'm going to come hard." If I hurt you, don't blame me for not saying hello beforehand! ”

Gupiko still hugged Han Xing and shouted: "My dear Commander Han Xing, I miss you so much, I finally see you today." You're my idol! I adore you the most, my dear aviation expert, tactician, weapons expert......"

He added so many titles to Han Xing in a row, even Han Xing was embarrassed, and hurriedly said: "You recognize the wrong person, in fact, I can't even fly a plane." ”

Kurishenko seemed to understand all of a sudden, took Han Xing's hand and said: "My dear commander of Han Xing, Gupiko often mentions to me that Han Xing's tactics, Han Xing's weapons, and Han Xing's aviation concept, it turns out that Comrade Gupiko is talking about you." Let's hug! ”

Kurishenko pulled Gupiko away at once, and then had the most intimate hug with Han Xing in the Soviet style.

This hug also made Han Xing a little excited and teary-eyed.

Zhang Xiaosan breathed a sigh of relief, and Wu Xiaoming and Li Dazhong also put away their guns and withdrew from the insurance.

Gupiko happily introduced Han Xing to Kurishenko: "There was an air battle in Xuzhou, and I admired the commander of Han Xing to the extreme. Their tactical philosophy, their weapon systems, their aircraft, I still have a mystery. It just so happened that the teacher came, and I wanted to learn from the teacher and ask the teacher for advice. Captain Kurishenko, don't you object to me calling Teacher Han Xing plus Comrade like this! ”

Kurishenko immediately said approvingly to Gupiko: "Of course, of course, you are an expert in destroyers, even you think so, what else do I have to say?" ”

Han Xing, Kurishenko, Gupiko, these three people almost hugged each other and walked into the third tarmac.

Xu Da shook his head helplessly, pursed his lips, and said, "I didn't want you to come in yet, but don't let you in!" In the blink of an eye, you're all eight. ”

These people walked up to the J-20 fighter, and first of all, the Soviet servicemen were attracted by the J-20's tall body and streamlined appearance.

Gupiko asked the first question: "May I ask Mr. Han Xing, your plane has no propellers, what force does the plane without propellers count on to propel the plane forward?" ”

Han Xing smiled and said unhurriedly: "The power of the plane is inseparable from the engine, and the plane drives fast and slowly, all counting on the engine to generate strong power. I know that whether it is the Yi 15 or the Yi 16, they all use rotary cylinder air-cooled star engines, and the principle of this engine is also inseparable from the principles of intake, pressure, explosion and exhaust. Our aircraft is different, it uses a jet engine, and the principle of the Yi-15 and Yi-16 is completely different.

Let me put it this way, the principle of jet is actually a pneumatic thermal duct. It does not have any major rotating parts, but consists of an expanded air intake duct and a convergent or convergent-expandable outlet. When it is forced forward by an external energy source, air is forced into the air intake. As it flows through this diffusion duct, its velocity or kinetic energy decreases and the pressure energy increases. Then, the combustion of the fuel oil increases its total energy, and the expanded gas is discharged into the atmosphere at high speed through the outlet duct.

Further, this method of compressing air in the engine is to rely on the relative airflow of the aircraft when flying at high speed into the engine inlet to decelerate, and convert kinetic energy into pressure energy (for example, when the intake speed is 3 times the speed of sound, the air pressure can theoretically be increased by 37 times).

When the engine is working, the high-speed air flow blows towards the engine, expands and decelerates in the inlet tract, and after the air pressure and temperature rise, it enters the combustion chamber and mixes with fuel oil (generally kerosene) for combustion, and the temperature is raised to 2000-2200 °C or even higher, and the high-temperature gas is then expanded and accelerated by the propulsion nozzle, and thrust is generated by the high-speed discharge of the nozzle.

The thrust of the engine is related to the intake velocity, for example, when the intake velocity is 3 times the speed of sound, the static thrust generated on the ground can exceed 2OO kN.

This is the practical application of Newton's third law of motion. 'Every force acting on an object has a counter-force of equal magnitude in the opposite direction, but this power is expressed as a tremendous force of fire or jet of air in the back. ”

The translator didn't really understand, and while he was lamely translating these words, Gupico and several officers hurriedly took out their pens to record them. Han Xing hurriedly stopped them and said, "My words are not allowed to be recorded. ”

"But we're friends!" said Gupico forcefully! ”

"Neither can friends," Han said, unyieldingly, "this is our principle." ”

Kulishchenk shrunk his neck, waved his hands away, and made a helpless movement.

Gupico then asked a second question: "Your weapon system is not a machine gun, not a machine gun, but ...... But...... A rocket-blazing one, and it's a no-miss. What's going on? ”

Han Xing said: "Whether it is Japan's 95-1 or 96-1, or the Soviet Army's Yi-15 or Yi-16, basically the weapon system is a machine gun, and the effective firing range of this machine gun is how many meters, that is, more than 1,000 meters." Even more powerful than it is the 20-mm cannon, which has a theoretical range of 10-15 km, but its accuracy is almost poor, and most aircraft are not equipped with it now.

And we are using missiles. The missile has the characteristics of fast response, good maneuverability, small size, light weight, and flexible and convenient use. Compared with aviation machine guns, it has the advantages of long range, high hitting accuracy and great power.

Close-range combat missiles mostly use infrared homing guidance, with a range of several hundred meters to 20 kilometers, mainly used in close-range combat, and have high maneuverability.

Air-to-air missiles are mainly composed of guidance devices, warheads, power units, and wings. Guidance devices are used to control missiles to track targets, and commonly used types include infrared homing, radar homing, and composite guidance.

The warhead is used to directly damage the target, most of them are equipped with high-energy conventional explosives, and their fuses are mostly infrared, radio and laser types of proximity fuses, and most missiles are also equipped with trigger fuzes.

The power plant is used to generate thrust and propel the missile to fly, and air-to-air missiles mostly use solid rocket engines. The wings are used to generate lift and ensure the stability of the missile's flight. ”
