With the oil from the Yumen Oilfield, the refinery began to produce various oils in small batches, and the hydraulic oil problem that Gu Xin'an had been a headache was finally solved. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 The self-production of info aid retirement aircraft greatly reduces the cost of artillery. It's a pity that none of the surrounding warlords can be sold, otherwise Qin Lang would want to be an arms dealer.

"Commander, the firing table of the 37 anti-aircraft guns has been compiled, and today the chassis is being tested."

Cheng Facai's diesel engine has also achieved some results, and is now able to produce a 20-horsepower air-cooled diesel engine. And on the basis of the tractor, several chassis were developed, all of which used balanced suspension without exception. This structure is suitable for light vehicles, simple structure and inexpensive. But after all, a tank is not a tractor, one can plough the land slowly, and the other can maneuver at high speed.

Of course, Qin Lang was not satisfied.

"The stroke of the load wheels is too small, and the cross-country ability is poor."

Due to the construction, the spring assembly cannot be made larger, so the anti-cushioning ability of the balanced suspension is limited, and the shock absorption effect can only be said to be reluctant. It also has the fatal drawback that it is prone to battle damage, and if one of the wheels fails, the entire wheel will lose its effectiveness.

"Commander, we are still working on the torsion bar suspension you mentioned, and it is currently in the stage of model testing, and it may take another year or two before the results are available."

Cheng Fa Cai's words are not shirk. Studying a mature chassis is not an overnight thing, not to mention a group of halfway monks.

"That slowly, we don't have this pressure now, and the chassis will solve the problem first."

In the place where he will fight in the future, he can make do with this kind of chassis, so Qin Lang is not in a hurry.

Seeing that Qin Lang was observing the chassis again, Cheng Facai quietly held the cross in his trouser pocket.

"Lord, bless me with this success!"

With the successful imitation of the 37th battle defense gun, Qin Lang asked for a motorized modification. The previous tests failed because of chassis problems.

"Boom!"

As clouds of black smoke rose from the tanker, the tankman drove the chassis through the rough terrain at a rapid pace. Because it was only a prototype, half of his body was naked, and it was only a circle of kung fu, and his body had already been covered by thick muddy water.

"It can move at speeds of 30 yards, is armored in nickel-chromium steel, has 10 mm front armor and 5 mm side rear armor, weighs 2 tons, is 2.6 meters long, 1.8 meters wide and 1.3 meters high. The engine is rear-mounted and the gearbox is also rear-mounted according to your requirements. However, there are still many problems, and they are being overcome one by one. ”

Now the mainstream tank gearboxes are front-mounted, one is because of balance problems, and the other is because of technology. After all, the rear of the gearbox is very troublesome to control, and if there is no boost, every gear change has to be exerted.

You must know that Mao Zi even dragged out the director of the Kharkov tank commander because of the problem of the gearbox. Of course, this kind of thing will not happen to Cheng Facai.

The reason why Qin Lang wants to make such a request is because the gearbox is front-mounted, and the transmission shaft is needed to send the power to the front. And this will make the hull "tall" and easily become a target for anti-aircraft guns.

"Boom!"

After another circle, the tank stopped on the side of the road, and several logisticians immediately added diesel fuel to the tank, and another person patted the tanker and shouted:

"Comrade Ding Dasheng, drive one more round trip, and you will park the car at the firing position."

"Yes, company commander!"

The man who drove the tank was the same person who fled the famine more than a year ago to starve the people. Now he is a tanker, because of his outstanding skills, he is now a key member of the experimental company.

"Boom!"

The engine was spewing black smoke again, and with a single pull of the lever he could, the tank began to rush forward again.

Because of the constant practice, the welder's skills have improved by leaps and bounds. So the entire chassis is welded, which greatly reduces man-hours. Now its shape is very smooth, and finally I can't see the dog-gnawed steel plate, which Qin Lang is very satisfied with.

"Boom!"

The tank stopped at the firing position, and a canvas target had been erected in the distance.

"Put your helmets on."

The people of the tank company immediately carried out an evacuation, and now there are only 4 people in the firing position.

"The target distance is 1000, and the anti-aircraft artillery firing team is ready!"

The gunner watched from the scope and kept shaking the high and low machine, and the muzzle of the gun was quickly aimed at the target.

"Aim done."

"Bang dang!"

A shell was fed into the chamber.

"Ready, put!"

"Bang!"

The whole car jumped.

Cheng Facai also shook it, but this time the chassis did not fall apart, which made him secretly relieved.

"Yes, the shell hit the target!"

Looking at the red flag waving in the distance, Qin Lang said with a smile.

"The second test subject, shooting at a target with nickel-chromium steel plates, at a distance of 1000, thickness 30 millimeters, and an angle of 90."

"Boom!"

There was another cannon shot, but soon a soldier appeared at the target. The red flag in his hand drew an arc.

"The shell missed, it was rubbed against the steel plate, and it should have been a little off when aiming."

Qin Lang didn't blame, after all, the battle defense artillery had only been manufactured for a short time. It is also normal that the gunner's training is not familiar, and the first direct hit is already commendable.

"Ready, set!"

"Boom!"

This time, the steel target was directly knocked down, and it seemed that those gunners were also holding back.

"Penetrated, good!"

When they saw the hole, everyone applauded.

However, Cheng Facai is not worried about this, he is only worried about his chassis, with the firing again and again, the chassis is up and down, and it looks very strong. But that's not what he's worried about, because the main event is coming.

After the defense gun was removed, a cannon was mounted on the chassis. This is the French M1897, 75mm gun. The recoil of the anti-aircraft gun is pediatric compared to it. And before that, there was already a record of 6 chassis damaged.

"Lord, bless your people this time!"

Cheng Facai became even more nervous, and even kept drawing a cross.

The guns and wheels of the guns have long been removed and mounted on the welded base, even if they are ready. It's just that the long barrel is mounted on this small car, which is very weird.

"Bang!"

The hoe behind the chassis was lowered, and everyone in the car ran away.

"Report, shooting ready, please instruct!"

"You can shoot!"

Cheng Facai quietly held a cross in his hand, and then closed his eyes tightly.

"Ready, put!"

"Boom!"

After the loud noise, the whole scene was silent, and Cheng Facai's heart immediately cooled in half.

No one applauds, which means that the chassis is finished.

He sighed heavily, but the moment he opened his eyes, he was stunned by what he saw. I saw that the chassis was safe and sound, but the front of the car was raised high, and if it weren't for the existence of the hoe, I am afraid it would have been reversed.

"The chassis is good, and the balance needs to be strengthened."

Qin Lang left.

Cheng Facai threw the cross in his hand.

"Put the chassis down, be careful!" (To be continued.) )
