Chapter 639： R twenty medium tank prototype (on)

As for Romania’s accession to the naval treaty, negotiations were quickly completed after Edelson’s mouth. As a result, there is not much difference. Romania has obtained a quota of 145,000 tons of capital ships, as well as corresponding quotas for other warships and aircraft carriers.

And this result also made Britain and France cheered, and finally put the stubborn little tiger in Romania in a cage. It is not bad for Romania, at least the strength and status of the Romanian navy is also recognized.

So starting in 1935, Romania started to build 1 battleship and 2 aircraft carriers, and other battleships also started construction. The naval shipyard in Varna is extremely busy, and Constanta and Odessa have also received orders for many small warships.

The expansion of naval vessels has made the Army look jealous, but compared to the Army’s new equipment is also under development. Among the three light, medium and heavy tanks proposed by Hoffman, the medium and light tanks finally have prototypes.

Next to the Second Machinery Manufacturing Plant on the outskirts of Lviv, there is a strictly protected armored research laboratory. This is currently the main tank research and development center in Romania, and the current director of the center is Herk. That's right, Helk, who was the first tank research trio before.

As for the other two, Biak is currently very interested in armored vehicles carrying soldiers, so it is leading the research of armored vehicles.

As for Wang, it is a long story. After World War I, Wang Chao forced him to return to China to fight for his dream of becoming a powerful country. No matter how the other two did not persuade them, they could only bless them in the end. However, Wang Chaoqiang, who returned to his motherland, was stunned by reality. The motherland of warlords melee makes Wang Chaoqiang's superb design ability useless.

Although he used parts to assemble the first car in the motherland and earned his reputation, he was struggling because of his fame. The car manufacturing plant opened in partnership with others cannot be sold at all. On the contrary, its ability to design tanks has a way out. Domestic warlords are very interested in new things like armored vehicles and tanks, which instead opened up the market.

But this is not the result he wants to see. In the end, frustrated, he can only return to Romania. After Edel's old friend came to power, he rekindled hope and returned to the motherland again. However, the basic industries of the Republic of China were even more unbearable at this time. Years of melee made the industrial base even less able to withstand automobile manufacturing.

For this reason, Wang Chaoqiang wrote to the government of the Republic of China, hoping that he can support his own development of the country’s automobile industry. However, this is useless. The financial and weak foundation of the Republic of China has left the book on the table. On the contrary, his years of experience in Romania have won the attention of the Ministry of Foreign Affairs and the military.

The former hoped that he could use his influence in Romania to get more aid from the Republic of China. The latter hoped that his ability in military industry would serve as a reference for choosing weapons for himself. And this result led Wang Chaoqiang to return to Romania again.

Fortunately, the other two knew its capabilities, and the trio continued to conduct research on Romanian tanks and armored vehicles. Wang Chaoqiang is currently leading the design of the heavy tank, but the design of the heavy tank is much higher than the other two, and the prototype has not yet been designed.

Today is the day when the military inspects prototype cars, so the inside of the center is extremely tense.

In the morning, several military vehicles drove into the R&D center. From the vehicle, a group of officers with generals came down, and the leader was a general with the rank of general.

That’s right, this time the inspection of the prototype car was led by Chief of Staff Felieit himself.

And Helk, who was the head of the center, greeted him immediately.

"Welcome the Chief of Staff to lead a team to inspect."

Looking at Helke with a smile on his face, Feleit, who had been here several times, spoke. "Helke, I hope this result will satisfy everyone."

"Definitely, you will be satisfied. This time, our design institute has been working for two years for the military project. We are still very confident about the results of this inspection."

Listening to Herk’s words, Feleit pointed to Hoffman on the side and said. "It's useless for you to say it to me. This is the one who tested you this time. I believe you are more familiar than me."

Looking at Lieutenant General Hoffman with a smile on his side, Herk’s smile became even brighter.

"Of course, of course."

After a brief greeting, the group, led by Herk, entered the research center. As the person in charge, of course, who is the protagonist this time, so he didn't introduce too much along the way, and he took them directly to the proving ground behind the design institute. In the proving ground, several R&D personnel are already conducting the final inspection on an unseen tank.

"Look, everyone, this is the new medium tank we have developed."

Herck, who led the team, was the first to introduce the results of this inspection.

"The car has a total length of 6.05 meters, a width of 2.9 meters, and a height of 2.86 meters. The car body is made of welding. It is divided into three parts. The driver and the electrician are located in the front part of the car body, and the middle part of the car body on the battle compartment. The rear part of the car body is equipped with an engine and transmission."

After talking about the distribution of the complete body structure, Herk continued to talk about other things. "The frontal armor thickness of the car body is 65 mm, but the 45-degree **** design is equivalent to 130 mm. The side body armor is 60 mm, and the 65-degree bevel design is also used. The armor protection is equivalent to 86 mm. The armor at the tail of the body is 30mm, mainly considering that the tail will not easily attack the enemy, and it is generally not used."

"In addition, the turret is also designed with a small upper and a large slope. Its frontal anti-shield is cast with a curved surface and has a thickness of 100 mm. The turret can be rotated by electric or manual devices. The electric rotation of the turret requires a period of time ranging from seconds. It is determined by the number of revolutions of the engine. There are two manual rotation handles, respectively at the gun length position and the loader position. A single handle rotates one rotation of the turret to rotate 0.866 degrees. If the turret rotates one rotation, it needs to rotate 415 times, and the two handles need 250 for simultaneous rotation. week."

"In addition, on the track, we use a 460mm wide track based on the terrain. Although this reduces the speed of the tank on high-quality roads, it makes it more suitable for complex terrain."

After speaking, he pointed to the skirt attached to the tank and said. "Based on the experience of the last battle, we designed this skirt. This can ensure that the track avoids inhaling a large amount of dust during high-speed driving, causing the tank to malfunction and causing unnecessary losses."

"In the suspension system, we use a parallel double torsion bar suspension system. Each rocker arm is connected to two torsion bars, one of which is directly connected to the rocker arm, and the other is returned from the opposite side to disperse the previous torsion bar. This design can ensure the balance of the tank, enough to ensure the accuracy of the tank’s shooting."

Having said so much, Helke finally said about the firepower of the prototype. "The barrel we designed for the new tank is a double tank gun. The gun was originally a 75mm anti-aircraft gun designed by RK, but because it does not meet the use of our air defense weapons, we used it as a tank gun after reducing the multiplier. The current gun muzzle velocity : 762 m/s, firing speed: 15 rounds/min. Armor penetration: 1000 meters at right angles to penetrate 109 mm, 1500 meters at right angles to penetrate 92 mmFor the RK company’s 75mm anti-aircraft gun, the presence Everyone knows. This was originally used as a medium-sized anti-aircraft weapon, but because Romania is used to using 88mm anti-aircraft guns, it is not recognized by Romania. However, I heard that the German side still recognizes this.

After talking about the tank’s artillery, Herke talked about power. "At present, the tank uses a diesel engine designed by the National Power Research Institute, which can drive a medium tank with a total weight of 35 tons to run at a speed of 45 kilometers per hour."

This diesel engine of the National Power Research Institute is its latest achievement, thanks to the good foundation laid by Diesel and sufficient financial support. Romania's research on diesel engines has always been at the forefront of the world. Whether for military or civilian use, Romanian diesel engines have a great reputation.

For this diesel engine, its maximum power speed is 1,900 rpm, and the maximum power torque is 2,752.5 N·m. And its safety and reliability are enough to ensure the use of the tank in complex terrain. Coupled with the tank's 480-liter large fuel tank, its maximum stroke can reach 480 kilometers.

But when Herk talked about the weight of the tank, Lieutenant General Huffman frowned secretly. Because the weight is 3 tons higher than the target of 32 tons, and the height of the tank is 16 cm higher. However, considering that he has not seen a field test of the prototype car yet, he wants to see it again.

As the leader, Admiral Filiyit said after the introduction by Herk. "Listening to you so much, let's take a look at its performance first."
