Towing artillery, even with the help of an all-wheeled off-road tractor, could not completely tow the gun to a predetermined position.

Therefore, when the artillery is removed from the tractor, it is generally necessary to be pushed by people to reach the predetermined position, which is a full physical work.

When the artillery is finished and the position is withdrawn, the same operation is carried out, the physical exertion of the gunner is large, the number of people required is large, and the speed is slow. Under modern counter-fire fire, this method is simply too slow and too dangerous.

Now, Qin Zhenhua proposed it, plus a special engine, it can be solved.

This engine doesn't need to be particularly big, as long as it can drive the gun to maneuver, no matter how slow it is, it is faster than the gunner pushing, right?

Moreover, in this way, the physical exertion of the gunners to push the guns by hand can also be saved, and the gunners can spend more energy on special firing and shooting.

This is simply tailor-made for towed artillery! Use it when entering and exiting positions, the effect is just right!

In fact, in the artillery bombardment, although it is said that the reaction speed of both sides is very fast, but, after all, the area covered by artillery fire is also limited, and it is enough for the artillery to transfer their positions as long as they move a few kilometers, and when the time comes, they can also recover and fire at the enemy's artillery positions.

In this process, there is no need to attach a tractor at all, and you can drive it directly with your own power.

This benefit alone made Xie Huimin see its tactical value at a glance, which was simply tailor-made for towed artillery!

Even if it is a 155-mm heavy gun, in fact, its own weight is less than ten tons, plus an engine of tens of horsepower, it is already very good, even if it is an old liberation, the engine is only a few tens of horsepower?

Using this kind of engine to drive the cannon, the main problem is not the lack of power, but the imbalance of the cannon, after all, such a long barrel, a bump may roll over, this is the most important problem to limit the speed, unless another twenty-ton chassis, but then the cost is high!

That's a really good idea! Xie Huimin's face was happy when he heard this, and at this time, Qin Zhenhua continued to introduce the usefulness of this method.

"In addition to being used when entering and withdrawing from positions, even when marching in peacetime, when encountering special road conditions, you can also start its engine to help pass, especially on muddy roads and sandy roads, and some sharp turns, which are beneficial."

A ten-ton cannon, even if it is towed by a truck with an off-road chassis, is not able to do it easily, after all, it is impossible for field troops to only march on the road, on some rural roads, in rain and snow, etc., many times it will be inadequate.

Sometimes, it is impossible to tow it, and it is necessary for the gunners to push the guns together, which is a great burden, and even in some places with sharp turns, it is impossible to drag the artillery through, and the car and the gun have to be separated.

With auxiliary power, everything is much better, and when you need it, turn on our power unit! Take the muddy section as an example, if the engine is turned on, the artillery itself is also powered, and the wheels of the artillery are also the driving wheels.

"Although we have not been in contact with our artillery, we can also know that such a large-caliber artillery, all kinds of operations are very laborious, seriously affecting the launch of the artillery, if the auxiliary power system is added, then you can use a variety of booster devices to achieve semi-mechanized operation and reduce the physical consumption of the gunner."

In self-propelled artillery, semi-automatic loaders have begun to be used, because large-caliber artillery, the handling and loading of shells are very laborious, and there is this condition in self-propelled artillery, so it is natural to have this condition.

What about towed artillery?

Not to mention such things as picking up and hanging guns, opening and merging frames, and taking off and landing guns, let's take the loading projectile as an example, more than 40 kilograms! That's right, it's this order of magnitude, equivalent to the weight of a junior high school girl, picking up a junior high school girl, although tired, but happy, but holding this cold cannonball is absolute physical work, a kind of physical work that makes people depressed.

Now, with the addition of this power system, it is natural to reduce the gunner's operating intensity through some assistance.

"That's right, you're right, we can try this!" Xie Huimin said.

"So, do you want to cooperate?" Qin Zhenhua asked.

In fact, if there is no cooperation, the second machine factory can also do it by their own strength, but if there is a machine factory to help, it will be different, the progress will be accelerated, perhaps, can catch up with the 8 * 910 project?

Thinking of this, my heart is warm: "Of course I need to, I hope you can help us." ”

"Okay, then let's sum it up." Qin Zhenhua said: "The engine power does not need to be too big, but it is best to use a diesel engine, our domestic 493 series diesel engine, just choose one to use." ”

Gasoline is not suitable, because gasoline is volatile, and if you fire a cannon while working and suddenly ignite the volatile gasoline vapor, the joke will be bigger.

It can only be diesel, although the vibration of the diesel engine is large, but the howitzer, relying on the face of the killing, a cannon past, an area the size of a basketball court is dead, at this time, the left side is one meter or the right side is one meter, and how much difference is there?

"If you turn around, it should be the easiest to use the rear gun tail wheel to control, and the principle we want to adopt should be as simple as possible, don't make this system too complicated, in short, it is a vassal of the artillery, a truck in the cannon, not a cannon in the truck."

When Qin Zhenhua said it, he was talking endlessly, and in the process, others could only look at him with helpless eyes.

Today, we are here to test the 125mm gun of our 85 tank, you are good, now Kan Dashan has reached the 155mm howitzer, this divergent thinking, it really makes people laugh and cry.

After this discussion, this day is about to pass! The cool breeze of Xi Xi blew on the grassland, and the air was filled with the smell of fresh grassland, and when I was about to end the day's work, suddenly, a news came.

The higher authorities officially decided to disarm a million!

Although I had already felt something, when this order came down, it still surprised many people, this is a big deal, the country's total of four million troops, disarming one million, equivalent to directly cutting a quarter!
