In the era of piston engines as aircraft power, a large part of the technology between tank engines and aero engines was common. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 infoIt's just that because of the different use environment and power requirements, there is indeed a certain degree of difference between the two.

For example, the engine displacement of an aero engine is more than twice as low as that of a tank engine. Both engines were developed from the same ancestor, so they had something in common in principle, but as technology continued to advance, the differences between the two began to emerge.

The displacement of the aero engine gradually increased, rising to a new height of 27 liters; At the same time, the engine of the tank has not been raised to this level, for example, the displacement of the tank engine being tested by the Ming Empire at this stage is only a little more than 11 liters.

Although it is not quite correct, it can be compared and analyzed by the displacement of the cars that people buy today. A 2.0-liter car is slightly inferior to a 3.0-liter car in terms of power performance, and at the same time, it is more fuel-efficient under almost the same load.

Of course, the premise of this fuel saving is only established when the unit weight does not exceed a certain value, and we do not need to delve into this data here. In short, aero engines can choose engines with larger fuel consumption and larger displacement due to the working environment, but the equipment on the ground cannot.

In fact, the reason is very simple: the plane often has a range of two or three hours and can reach a distance of 1,000 kilometers, but if the tank is only given two or three hours of travel time, its radius of activity may be only a short 100 kilometers -- this is obviously the result that all tank commanders do not want to see.

On the other hand, the air intake of the engine in the sky is quite pure and consistent. Even in extreme environments such as deserts, the air in the sky is better than near the ground, so aircraft engines can be designed more precisely, while tank engines need to be more conservative in terms of failure rates.

Moreover, for tanks, an engine that is needed more than it actually needs means burning more fuel, carrying more fuel means adding more volume to the hull, and adding more volume often means requiring more armor weight, which requires larger and heavier shock absorbers and wider tracks...... If this vicious circle continues, the end result is only a super heavy tank, not a faster tank, which is contrary to the original pursuit of a powerful engine.

Therefore, now that the Ming Empire actually has a 1000-horsepower engine, Zhang Shiyang, who designed the chassis of the No. 2 tank, is simply unwilling to replace the THS engine and supporting transmission originally prepared for the No. 2 tank.

What's more, under the current conditions, the THS engine performed very well on the chassis of tank No. 2, at least in many ways to meet the various needs of the military. In fact, the needs of the military at this stage are also very vague and unclear, and no one knows what the tank will develop into in the future.

However, the Ming Empire has the world's richest tank combat experience, and also has the new army, an army system that is willing to accept new things, so the Ming Empire's tank research and development is at the forefront of the world, at least in terms of design experience, it has an incomparable advantage in many countries.

For example, Zhang Shiyang and his R&D team, almost after the birth of the chassis of the No. 2 tank, they came up with a lot of corresponding tank or support vehicle designs.

The No. 2 assault gun was based on the chassis of the No. 2 tank, with a larger fixed fighting compartment and a 75 mm long-barreled gun - the same design as the No. 1 assault gun, but with a more powerful gun.

Similarly, the design of the support gun of the No. 2 tank was taken out in a matter of days, and the plan was just as sloppy and crude: the engineers directly expanded the design of the No. 1 100 mm self-propelled howitzer and installed a 150 mm cannon, even if the corresponding design was completed.

Compared to the No. 2 tank, these two weapons did not have any difficulty in design at all, they came out a little earlier than the No. 2 tank, and when the chassis of the No. 2 tank began mass production, it was directly produced into the No. 2 assault gun and delivered directly to the army of the Ming Empire.

Of course, all this is an afterthought, and now Zhang Shiyang is working hard to complete the overall design of the No. 2 tank - including the high-tech turret, as well as the 50mm long-barreled gun that he is very troubled with, and the corresponding armor-piercing ammunition.

These designs are all weapons developed in accordance with the requirements of the military and are prepared to counter the unwarranted so-called "tank equipment of hostile countries". Their primary purpose is to destroy enemy tanks and ensure the safety of their own tanks and other vehicles and personnel.

For the same reason, the No. 2 tank hull of the Ming Empire, after being changed and strengthened, finally selected the front armor with a thickness of 50 mm, in order to give the opponent's army equipped with anti-tank weapons a "surprise" in future battles!

It can be said that the No. 2 tank designed by Zhang Shiyang is a kind of "tank killer" specifically aimed at future enemy tanks. It is an imaginary enemy weapon that uses the opponent's tank, and it is also an expanded and ultimate enhanced version of the No. 1 tank.

The reason for the reinforcement is because even in the later stage of the Liaodong battlefield, the backward Jin State and the Japanese army units found a lot of anti-tank weapons, which posed a considerable threat to the No. 1 tank and No. 1 assault gun of the Ming Empire. Obviously, these cheap anti-tank weapons will equip troops on a large scale in the future and become an intermediate force in the fight against tanks in various countries.

First of all, there are a lot of 50 mm and 75 mm caliber guns, these original light infantry guns, against the No. 1 tank, have a great advantage in caliber, these unprofessional guns can fire at a long distance, the formation of suppression of the No. 1 tank.

Although the ballistic performance is not good, and although there is no direct sight for the time being, these guns pose a considerable threat to the No. 1 and other Tank No. 1 extensions. And the development of sights and more suitable gun mounts is obviously a very easy thing to do.

In just two or three years, a large number of special anti-tank anti-tank anti-aircraft guns will be born in various countries, and these guns may use smaller calibers, use larger muzzle velocity guns, and increase penetration to achieve anti-tank purposes. This is also the result of the Ming Empire's self-speculation when it developed a special high-speed gun of 50 mm caliber.

Soon, about 50 mm special anti-tank guns, 75 mm caliber and even 100 mm caliber artillery will appear in the sequence of various armies, and the tanks of the Ming Empire will need to pay an even more tragic price if they want to achieve such an overwhelming victory on the battlefield in Liaodong.

"It's not good, our No. 2 tank, before it came out, has already been made obsolete by the anti-tank weapons of various countries." Zhang Shiyang, who watched the 50 mm caliber anti-tank gun test firing ammunition and penetrating a homogeneous steel plate with a thickness of 30 mm at a long distance, said to Chen Zhaoming, who was worried beside him.

Chen Zhaoming also saw the results of this experiment, although the front of the chassis of the No. 2 tank is made of homogeneous steel plate with a thickness of 50 mm, and the protection capacity is much better than that of the 30 mm thickness, but this still cannot guarantee that the new tank has an unbreakable advantage in the face of anti-tank weapons.

"In this case, we can only compensate for the lack of quality of the equipment itself with completely new tactics, according to the commander." Chen Zhaoming said to Zhang Shiyang with some helplessness: "We can't make the tank heavier, installing thick armor will overwhelm the tank's shock absorption system, and it is unknown whether the chassis of the No. 2 tank can meet the improvement requirements at that time." ”

"When designing the No. 2 tank, I took into account the margin for improvement." Zhang Shiyang complained to Chen Zhaoming with a smile and a smile: "However, now I find that the development is still much faster than I imagined." ”

"There's no way around it, and we're constantly learning and growing." After Chen Zhaoming finished speaking, he changed the topic and talked about other things. He didn't want to put too much pressure on a designer like Zhang Shiyang, who was energetic and thoughtful, and from Zhang Shiyang's body, he saw his shadow when he was in the new army.

"You have to keep an eye on the mass production of chassis No. 2, strictly control the quality, and after the TY-3 engine is successfully changed to a ground model, strive to make the No. 2 tank use thicker armor!" Ending the topic of data on the chassis of tank No. 2, he shifted the conversation to mass production: "Within a year, the military will have an order for a full 5,000 chassis ......"

Zhang Shiyang was very sure of this matter, and hurriedly assured: "Please rest assured, Director, when the No. 2 tank was designed, it was designed with reference to the record of mass production equipment, and it was completely designed in accordance with the wartime mass production process, and there is no problem in producing 5,000 units a year!" ”

Chen Zhaoming waved his hand and said to Zhang Shiyang: "Don't rush to give me assurances, what I want to see is the results!" When the No. 2 chassis reaches the production requirements, we will suspend the production of the No. 1 chassis...... Time, what we lack the most, is time! ”

"Yes! I understand! Zhang Shiyang nodded and said to Chen Zhaoming: "I will bring your decision to Mr. Tan Jincheng, the chairman...... Oh, I heard I should call him Wairo-sama. (To be continued.) )
