"Good, we're meeting again." Somewhere in the north of the Han capital, in the tank force shooting range, Qin Zhenhua and other representatives from a machine factory finally met the main owner, those arrogant British, who were complacent and waiting for the next test gun.

The one who talked to Qin Zhenhua was the same Robert he had seen at the beginning, and at this time, when he saw Qin Zhenhua, the meaning in his words was obvious.

Bragging, you used to brag, and now, we're finally going to get serious, let's see how you guys are still cheating!

Marshal Cameron didn't come in person, he was still in the capital of the Han Kingdom, discussing all kinds of friendly issues with some senior officials, and only sent these technicians over, and now, they just want to see how the Han side is making a fool of themselves, whether the powerful armor-piercing bullets they claim are there, and it is absolutely impossible to cheat now.

Marshal Cameron is actually waiting for this competition.

"yes, meet again." Qin Zhenhua communicated with the other party in fluent English, and now, it has just entered April, and there is still a slight chill in the north, but the land in the shooting range has begun to emerge green shoots, showing the arrival of spring.

"Look, this is our L7 tank gun." Robert pointed to everyone, in fact, there is no need for him to say, this tank gun, and domestic tank guns, can also be seen from the appearance of obvious differences.

The device in the middle of the barrel is the most dazzling, and it is the barrel smoking device.

Our own 100mm tank guns, every time they fire, there is always a part of the smoke pouring out from behind, and it instantly permeates the entire turret inside, if you fire continuously, the gunners will soon be choked and can't stand it, even if the exhaust fan inside rotates wildly, it will not work.

This is caused by the lack of a barrel smoke extraction device, and now the opponent's tank gun has a complete smoke extraction device, which can greatly reduce the smoke pouring into the turret.

In addition to this smoke extraction device, there is a thermal sheath that covers the entire barrel, which is made of aluminum alloy and is sleeved on the outside of the tank gun, which makes the tank gun look thicker.

This thermal sheath is to prevent the thermal expansion and contraction of the barrel of the tank gun, yes, in order to achieve a high enough accuracy, even such a small change in the thermal expansion and contraction of the barrel needs to be taken into account. In the sun, the part that has been baked on it will expand, and the barrel will bend downward, even if the curve is quite small, it will cause a certain error in long-range shooting.

This barrel is mounted on a modified 69 tank of his own, and in the past few days, Marshal Cameron has visited the capital, and these people, right in the army, have converted such a tank.

"Their tank guns, it's easy to modify." At this time, when everyone was studying this tank gun, Zhu Lao on the side spoke.

The last time he went abroad, Zhu Lao didn't go with him, but what happened throughout the whole process was clear, and he admired Qin Zhenhua's strategy, this time the British came here, brought tank guns, and modified them, and Zhu Lao saw the whole process.

In terms of fighters, the engine of their own fighters has to be disassembled, and the entire rear fuselage has to be disassembled and tossed for a day or two, while the Western fighters can be completed in fifteen minutes by opening directly below.

Tank guns, too, are similar.

Your own tank, when changing the tank gun, has to hoist the turret and toss for half a day, while the L7 tank gun can be stuffed directly from the outside, and there is no need to hang the turret at all.

This kind of tank gun is a must be introduced by one's own side, not to mention anything else, it is very easy to use this gun to transform one's own 59 tank, and if the previous 100 mm rifled gun is changed, the power will be greatly increased, and the adaptability is quite good.

Qin Zhenhua jumped on the turret and looked at the structure inside, and couldn't help but nod in admiration.

Relying on advanced technology, the barrel of this tank gun is much lighter than its own barrel, and the reduction of mass reduces the rotational inertia and makes it more convenient for the turret to rotate.

The interior of the 59 tank has a small space, and the various mechanisms behind the barrel almost divide the turret into two, and now, this mechanism, compared with its own, has shortened a considerable distance, especially the efficient stationing/re-entry machine behind it has further reduced the volume of the gun tail, which has greatly improved the space inside the turret.

"How?" Robert asked Qin Zhenhua, in fact, Qin Zhenhua is just a small role, those present, take out any one, they all have a higher status than Qin Zhenhua, but last time in the UK, Qin Zhenhua left a deep impression on them, and repeatedly made them unable to get off the stage, and later he personally proposed to compete, and Qin Zhenhua can speak English and can communicate directly, so in this way, Qin Zhenhua has become the inevitable target of the opponent's verbal dispute.

"Not bad." Qin Zhenhua said: "The design of the tail is very good, and the internal space of the turret is increased, which is worth learning from. ”

Hearing Qin Zhenhua's words, a victorious smile appeared on the faces of Robert and the others: "So, your tank guns are still not as good as ours, aren't they?" ”

"I'm talking about other attachments, and in terms of armor-piercing power, we're not inferior." Qin Zhenhua said to the other party: "We are full of confidence in the shells of our tank guns. ”

As soon as this sentence came out, the expressions on the faces of Robert and the others suddenly became solemn: "Okay, then let's compete to see who has stronger armor-piercing ability!" ”

In the past few days, when they were converting the L7 tank gun to the 69 tank, they were also studying the 100mm smoothbore gun that was dismantled.

The metallurgical technology here is obviously not high enough, in order to withstand higher chamber pressure, the tank gun is very thick, at the same time, don't look at the large volume of the tail door, but the charge of the projectile is not as much as your own L7 tank gun, after all, your own 105 mm barrel, the opponent is 100 mm, the larger the caliber, the more naturally the charge.

Therefore, if the other party can penetrate armor higher than his own, then he will never believe it.

"You're guests, or you'll come first." Qin Zhenhua said: "How to compare, you have the final say." ”

When comparing, there are many prerequisites, and the results obtained will naturally be very different if the constraints are different.

Hearing Qin Zhenhua's words, Robert smiled and said to him: "We are better than the armor-piercing ability at a distance of two thousand five hundred meters. ”

His smile was full of cunning.
