Chapter 185 The Importance of the Saber Killer’s Push-to-Weight Ratio

The different colors of the gas ejected from the tail nozzle also indicate different temperatures. The dark red temperature indicates that the temperature is around 600 degrees, and the deep red color indicates that the temperature is around 700 degrees.

Then it slowly turns into orange-red, which is one thousand degrees. The temperature of pure orange is one thousand one hundred degrees. The temperature of golden orange is one thousand two hundred degrees. The temperature of golden yellow is about one thousand three hundred degrees. The temperature of golden white is one thousand. Fourth, pure white has reached more than 1,500 degrees, blue-white has reached 1,500 degrees, and sky blue has reached more than 2,500 degrees.

Of course, the current situation means that the tail nozzle of the turbojet engine is about five or six hundred degrees when the afterburner is not turned on, but it has reached a thousand degrees after the afterburner is turned on.

However, it only lasted less than a minute before Liu Qin had to turn off the afterburner of the turbojet engine.

Of course, this is not because Liu Qin is reluctant to consume fuel, but the tail nozzle of the turbojet engine has begun to turn orange and has some slight deformation.

Yes, although the tail nozzle of this engine is made of steel with a melting point of more than 1,500 degrees, this does not mean that it can be used at high temperatures of 1,500 degrees.

In fact, the strength and toughness of steel remains unchanged when the temperature is within 300 degrees. However, as the temperature increases, the strength begins to weaken. When it reaches 500 degrees, it is only one-half of the original strength. At 650 degrees, the strength is basically the same. It was only one seventh or even lower.

Therefore, as the temperature of the tail nozzle increases to a thousand degrees, the tail nozzle begins to be somewhat deformed by the high-speed and high-temperature airflow.

If it is allowed to continue like this at this time, the tail nozzle will be deformed and scrapped, and then the entire turbojet engine will lose power.

At this time, Liu Qin stopped the turbojet engine of the ME262 fighter jet and asked Liu Xiu:

"Now that the afterburner of the engine is finished, do we need to design the fuselage of the fighter jet? Should we still use the original ME262 fuselage, or should we redesign the fuselage?"

Because of Liu Xiu's outstanding performance after possessing the ability to think explosively, Liu Qin now asks Liu Xiu for his opinion on some key issues.

Liu Xiu naturally shook his head after hearing Liu Qin's words. He did not plan to use the fuselage design of the ME262 fighter. Because it was the first jet fighter, the ME262's fuselage design also referred to the propeller fuselage design. This is undoubtedly a Wrong choice.

The test just now on the thrust platform also showed that its thrust is indeed the same. Its maximum thrust has changed from the original 900 kilograms to more than 1,300 kilograms after afterburner is turned on. The power has increased by about 100 percent. More than forty!
Although this method of increasing thrust is not sustainable in combat, it is enough for Liu Xiu. After all, afterburner is only used in combat, and there is no need to turn on afterburner during normal flight.

However, the temperature of the gas ejected by the turbojet engine directly determines the most critical performance of the turbojet engine, which is thrust. Liu Xiu heard a sentence before traveling through the world, saying that every time the jet temperature of the turbojet engine increases by one hundred degrees, Its propulsion power can be increased by ten percent.

You must know that propeller aircraft have insufficient thrust, so the wings are vertical to the fuselage to obtain a higher lift-to-drag ratio, but jet aircraft are different. The high-speed characteristics given by the turbojet engine give the aircraft obvious advantages at high speeds. .

Vertical wings are obviously not conducive to increasing the speed of aircraft, so since the advent of jet engines, basically all aircraft have used swept wings, so Liu Xiu naturally cannot make this mistake again.

As for how to design a new fuselage, Liu Xiu actually had an idea in mind. After all, he was a time traveler, so as a time traveler, he naturally knew who the Mi Army's saber killer was! That's right, the MiG-15's Saber killer is not the MiG-15. Although the MiG-15's 37mm cannon can send the Saber back to the west with one shot, it is useless if it misses, and the Saber's six 12mm cannons Although the machine gun firepower is intensive, it is useless if it cannot hit continuously.

Therefore, on the battlefield to aid Korea, the two jet fighters were evenly matched. There was no absolute winner over the other, nor did they achieve an absolute battle loss ratio!
However, there is a small fighter plane that can defeat the Saber, and it is also known as the Saber Killer. This fighter is the Zuna fighter developed by Yinguo in 1950 and first flew in 1955.

The reason why it is called a small fighter is because the length of this fighter is only 9.6 meters, the width is only 7.3 meters, and the height is only 2.9 meters. It is even smaller than some propeller aircraft.

Of course, with such a small size, its weight is naturally light. Its empty weight is only 2.1 tons, and the maximum take-off weight is only 3.9 tons.

However, despite its small size, its thrust is quite large. In order to ensure its flexibility, Yinguo directly gave it a turbojet engine with a thrust of 2.1 tons.

Of course, the Zuna fighter also followed the path of the MiG-15, with two 30mm-caliber cannons installed on a fuselage of just over two tons in the air.

The reason why the Zuna fighter is called the Saber killer is mainly due to its excellent maneuverability. You must know that the Zuna fighter is small in size and weighs 2.1 tons, while the empty weight of the Saber reaches 4.5 tons. It is the Saber. Less than half of that.

However, the power systems of the two, that is, the power of the turbojet engine, are not much different. The thrust of the Saber's turbojet engine is only 2.3 tons.

Therefore, with such a large power gap, the excellent flexibility of the Zuna fighter is naturally created.

Of course, no matter how good the data is, you have to go to the battlefield to know. Naturally, it was the two wars between the Sheep Kingdom and the Elephant Kingdom that made Zie Na famous.

Among them, the Sheep Kingdom purchased the Sabre, while the Elephant Kingdom purchased the Zie Na. The result was that the Zie Na defeated multiple Sabers one after another.

The most famous one is that in the battle of 1976, Zuna's single plane was surrounded by six Sabres. However, Zuna relied on its excellent maneuverability and was shot down after shooting down two Sabers.

Naturally, we can see the superior performance of the Mosquito fighter against the Saber!

Of course, with the development of technology, especially the development of air-to-air missiles, air combat between fighter jets has become a thing of the past. What the two sides compete with is whose air-to-air missile has the longest range and the most power.

However, the development of the first generation of air-to-air missiles took five or three years before the Sidewinder air-to-air missile appeared. What's more, even if the Sidewinder missile was developed, the shortcomings of the first generation Sidewinder missile were that the hit rate was less than 100%. Fifty, not as effective as a machine gun.

Therefore, if Liu Xiu comes out with Zina now, not only will it not become outdated, but it will also form an absolute advantage over the American Sabers in the air combat battlefield to aid Korea!
However, the biggest headache for Liu Xiu now is the lack of industrial strength. Even if Liu Xiu can come up with the drawings, he cannot produce them. For example, the steel rolling mill used to make the fuselage will not be completed until May 1950!
