On the same timeline, Zhang Shiyang stood between his master and a large group of veteran engineers, analyzing two very different design drawings. Pen & Fun & Pavilion www.biquge.info are both competing designs for Tank 2, and at least on paper, the styles between the two designs are very different.

Some of the old design experts, when designing the No. 2 tank, felt that they should learn from and make use of the successful experience of the No. 1 tank, and they advocated referring to the No. 1 tank and designing and building a new type of tank that meets various needs according to the various needs of the military.

Based on this design concept, they proposed a conservative design scheme to enlarge the No. 1 tank: the hull of the No. 1 tank was widened by 10 centimeters, then the hull was extended by 41 centimeters, and a load wheel and a track carrier pulley were added to increase its interior space and dead weight.

Although this scheme is relatively conservative, but it is stable and reliable, the No. 1 tank has been in service on the battlefield for half a year, most of the problems exposed have been clear at a glance, after the improvement of these technologies have been relatively mature, to use it of course has advantages. On the other hand, this design meets the military's requirements for the addition of a 50 mm caliber high-speed tank gun, which can be used as an alternative to the next generation of tanks.

What Zhang Shiyang was holding in his hand was the design of the new hull of the No. 2 tank completed by some young people under the guidance of several more radical old design engineers. This scheme is much more radical than the previous Enlarged Hull Version of Tank 1.

Compared to the first plan, this car body is almost redesigned, so many places are actually not perfect, after all, it has only gone through more than ten days from the beginning of the drawing. Of course, although this plan is still a long way from direct production, it has the support of some experts and military representatives because it has incomparable advantages over the previous one.

The second scheme adopts a simplified design in the structure, and uses an improved external spring balance shock absorber, which is more professional and perfect than the shock absorption used in the No. 1 tank, and the reliability and shock absorption efficiency are relatively higher.

In conjunction with this damping system, this second design features a larger body, which also increases the amount of space inside the body for fuel and ammunition. After a simple comparison of assumptions, Zhang Shiyang believed that the body he designed could theoretically be equipped with a 75mm gun, and there was more room for improvement.

On the one hand, there was an expanded version of the sufficiently functional and technically mature No. 1 tank, and on the other hand, a radical scheme that was thoroughly improved but not technologically mature. The two designs, each with its own advantages and disadvantages, made it difficult for everyone to choose, and each side came up with better design drawings and theoretical inferences in an attempt to make their design the final style of the Reich 2 tank.

William? Arsene Wenger also rushed over from his engine research and development lab, where he was working on the THS-2 petrol engine, along with its accompanying gearbox, which would eventually become the powertrain for the new tank chassis. However, this engine has been in the experimental stage until now, and the output power has not met the requirements of the military.

The military hopes that this new water-cooled engine can continue to output more than 350 horsepower. As a result, William? Arsene Wenger's design team was only able to make this THS-2 engine reach a sustained horsepower output of 290 from beginning to end. If you talk about the peak output, the THS-2 can soar to 330, which is not too far from the military's requirements, but this output cannot be sustained, and it is easy to damage the engine when it is often overloaded.

The slight lag in the powertrain made the main person in charge of the development of the No. 2 tank more inclined to the lighter version of the enlarged No. 1 tank. But a few stubborn leaders seem to prefer a better-looking new tank chassis – and among the few senior leaders who are optimistic about the radical version is Tan Jincheng, the hard-sighted and stubborn boss of Chiyou.

"First of all, if you simply enlarge the chassis of the No. 1 tank, the criticized shock absorption system will be inherited as it is...... This is something I personally don't want to see. The chairman of the Chiyou company stubbornly clarified his point of view to several heads of tank design: "What I want is progress!" It's development! So that my company can always sell the best and most advanced weapons, which is why I have the money to hire you...... Isn't it? ”

"But, Mr. Chairman...... If we adopt a more radical approach, the first and most difficult point to break through is that the power of the engine cannot meet the requirements of the military. An engineer complained to Tan Jincheng: "Although the car body space is large, we can't think of anything to stuff in." ”

"You design engineers don't have to worry about the engine, two parallel engine design teams are working hard to develop two different engines, and we will always get a better, more powerful new engine, right?" Tan Jincheng ignored the complaints of his subordinates and stubbornly refuted the other party's reasoning.

His stubbornness gave Zhang Shiyang, a young tank designer, endless courage, so at the right time, he took out a large stack of reports full of dense analysis data in front of Tan Jincheng, and said his thoughts to other designers: "We should set up another loader for the new tank...... This frees up the commander to concentrate on directing his tank, receiving orders from his superiors on the radio, and observing what is happening around the tank......"

"5 tank crews?" Tan Jincheng also had a general understanding of some of the data in the tank, and after he heard Zhang Shiyang's proposal to add another loader, he looked at the other party who was a little nervous in surprise. Then the boss of the largest arms company in China raised his hand and motioned to the young man in front of him to continue his introduction.

Zhang Shiyang seemed to be encouraged by Tan Jincheng, he pondered for a few seconds, and then introduced: "The military has been responding to the confusion of the division of labor among the members of the tank and the inefficiency of command...... So I think it's important to add a loader to the larger hull and have him work with the gunner. This allows the commander to concentrate on commanding the tank and judging the situation on the battlefield. ”

An engineer took the thick stack of analysis reports from Zhang Shiyang's hand, nodded and said, "You convinced me, young man!" ”
