In the foreseeable future, the first thing to determine the maximum itinerary of the ground armored vehicles is vehicle suspension, followed by the power system.

The first sentence of the document grabbed Liang Yuan's attention tightly.

However, an excellent power system can improve the battlefield survival rate of armored vehicles.

Looking at the second sentence, a smile appeared on the corner of Liang Yuan's mouth. Although his main business was in the sky, he had a good understanding of the guys on the ground.

As we all know, the performance of ground armored vehicles on road systems has never been the focus of design and optimization. In the past world war, it has shown that a complete road system has always been a very luxurious resource on the battlefield. When the power system is sufficient, the off-road speed of the tank vehicle is the decisive factor that determines the maximum itinerary of the tank.

When the power of the tank engine exceeds 1,500 horsepower, the main factor that prevents the tank from increasing off-road speed is no longer insufficient power, but humans cannot withstand greater bumps in a limited space like a tank.

Excellent suspension can increase the maximum off-road speed of the tank vehicle. When the power is sufficient and the fuel is limited, the higher the maximum off-road speed, the higher the maximum range of the tank will of course be.

However, in war, the speed of on-the-ground advancement is only effective at a macro level similar to a battle. Motor power is the real data to improve the survival rate of armored vehicles on the battlefield. To be more precise, on the real micro battlefield, maneuver power is agility, maneuver power is steering, and maneuver power is acceleration.

For ground armored vehicles represented by tanks, an excellent suspension system determines the agility of the tank, and a high-power heart is the only magic weapon to increase acceleration.

This is also the most important reason why the two superpowers of the United States and the Soviet Union spent huge amounts of money to move gas turbines onto tanks.

Of course, the repeated application of gas turbine units in tanks in the future is nothing more than the international military that significantly reduces the probability of large-scale armored battles. If the world war cannot be fought, the high fuel consumption and high cost of gas turbine units must be extremely dazzling.

If we ignore the technological progress that has occurred over time, the global arms development idea during the Cold War was to achieve performance as the king for the purpose of winning the enemy. As long as the chance of defeating the enemy can be increased, it is not a problem to increase the cost relative to the cost. The global arms after the fall of the Soviet Union were aimed at saving money. The retirement of the F14 fighter jet, the withdrawal of the gas turbine from the tank's power system, and the scam f35 fighter jet project are typical cases of this idea.

In Liang Yuan's opinion, the performance of the m1a1 tank drinking fuel in the Gulf War cannot explain any problem. That war is more like a marching than a battle. The advantages of gas turbines such as low noise, high torque, and strong explosive power cannot be displayed at all, but their weaknesses are fully demonstrated.

If Iraq is equipped with diesel-powered m1a1 tanks, the two sides have fought several large-scale armored battles. Liang Yuan believes that the reputation of gas turbine units in tank applications is definitely another kind of limelight.

No one in this world is a fool. After the Gulf War, even though the gas turbine unit was sprayed into slag by many military experts due to fuel consumption, the economically abundant Republic in the future still repeated the past of the United States and the Soviet Union, trying to move the gas turbines to tanks. What is the purpose of? It's just that they have different ideas on building each other's army.

For the Republic at that time, improving the military's combat power and doing its best to increase the chance of regaining Taiwan was the first choice.

After turning over the homepage of the outlined document, a table marked (*non-public information is for reference only*) filled with various data came into Liang Yuan's eyes.

Soviet T-80b tank (42.5 tons): The power core uses the SG-1000 gas turbine, the engine calibration power is about 746 kilowatts (1000 horsepower), and the maximum internal fuel load capacity is 1100 liters. The maximum road trip is 335 kilometers, and the fuel consumption is about 328 liters/100 kilometers.

The American m1a1 tank (57 tons): The power core uses agt-1500 gas turbine, the engine calibration power is about 1103 kilowatts (1500 horsepower), the maximum internal fuel load capacity is 1900 liters, the maximum road trip is 463 kilometers, and the fuel consumption is about 410 liters/100 kilometers.

Federal German Leopard 2a4 tank (55 tons): The power core adopts the mb873ka-501 4-stroke 12-cylinder V-type water-cooled pre-combustion chamber-type supercharged intercooled diesel engine. The engine calibration power is about 1100 kilowatts (1500 horsepower), the maximum internal fuel load capacity is 1200 liters, the maximum road trip is 550 kilometers, and the fuel consumption is 219 liters/100 kilometers.

Leclerc's main battle tank (53 tons): The power core uses a v8x1500 ultra-high supercharged diesel engine. The engine calibration power is about 1103kw (1500 horsepower), the maximum internal fuel load capacity is 1300 liters, the maximum road trip is about 550 kilometers, and the fuel consumption is 6 liters/100 kilometers.

Japan's Type 90 main battle tank (50 tons): The power core uses Mitsubishi two-stroke water-cooled V-type turbocharged diesel engine. The engine calibration power is about 1103 kilowatts (1500 horsepower), the maximum internal fuel load capacity is 1200 liters, the maximum road trip is 350 kilometers, and the fuel consumption is 342 liters/100 kilometers.

China Type 59-2 medium tank (36 tons): Power core b2 series V-type 12-cylinder water-cooled diesel engine, engine calibration power is about 382 kilowatts (520 horsepower), maximum fuel load capacity is 812 liters + 200 liters. The maximum road trip is about 500 kilometers, and fuel consumption is 202 liters/100 kilometers.

Swedish St. Dsvagn103c tank (42 tons): power core 6v53t inline 6-cylinder water-cooled diesel engine + Caterpillar 533 gas turbine combined drive, engine calibration power is about 216 kilowatts + 365 kilowatts (780 horsepower), maximum internal fuel load capacity is 960 liters, maximum road trip is about 390 kilometers, and fuel consumption is 246 liters/100 kilometers.

The following conclusions can be roughly drawn from the performance data on the surface of main battle tanks of various countries:

If the Japanese Type 90 tank that is incomprehensible is removed, the fuel consumption of tanks using gas turbine units as the power system is significantly higher than that of diesel units.

However, it is worth noting that Swedish tanks have a unique approach. The fuel consumption of Swedish STD DSVagn 103c tanks, which are driven by diesel fuel, is only slightly higher than that of diesel units. What is more prominent is that although the Swedish 103c tank ranks in the middle of ton of power, the tank has excellent maneuverability, with an acceleration time of only 6 seconds from 0-32 kilometers, second only to the French Leclerc tank that uses 1,500 horsepower...

This analysis has more than ten pages, and uses numerous data to compare the advantages and disadvantages of the gas turbine unit, diesel unit, and diesel unit.

Then it was concluded that the Chai Ran joint drive power core is an excellent choice for ground armored vehicles.

After reading this passage, Liang Yuan looked back and looked through the data and found that except for the Russian T80 tank, the data of other tanks were basically similar to the information slowly revealed in the future. However, Russians have a long tradition of counterfeiting weapon parameters, such as the scam-free aircraft engine push ratio.

In the future, even Liang Yuan, who is not very concerned about army equipment, knows that in the brochure issued by Ukraine, the real fuel consumption of t80u tanks using GTD1250 gas turbine units on the road is more than 430 liters.

After this summary of the current status of the tank power system, several three-view and simple internal structure diagrams appeared in front of Liang Yuan.

"The wz1224 tank experimental vehicle is equipped with a gem turboshaft engine and a digital calculation simulation of the joint drive system of the b2-type v-type 12-cylinder water-cooled diesel engine."

Looking at the tank with six pairs of heavy wheels and the short text below the three views, Liang Yuan suddenly realized that the heretic with six wheels outside the gas turbine workshop should be the wz1224 tank experimental vehicle mentioned in the document. The remaining "five-wheel orthodox" should be a test platform for providing a B2 series diesel engine.

As a senior naval fan of the Republic, Liang Yuan naturally did not know the unique status of the wz1224 tank test vehicle in the history of armored vehicles in the Republic.

The wz1224 experimental tank, which was established in 1978, was regarded as the third-generation main battle tank in which the Republic skipped the second-generation tank and directly pre-researched. At that time, many Western tank design ideas were used. The turret used the fashionable wedge-shaped welded turret and replaceable composite armor that greatly enhanced the frontal defense. The artillery chose a large-caliber 120 smoothbore tank gun.

The power system uses a 1,000-horsepower longitudinal engine that can be hoisted as a whole. The transmission part uses a fixed shaft hydraulic mechanical gearbox, a secondary planetary steering mechanism, and hydraulic assisted operation. The chassis part uses six pairs of small-diameter steel load-bearing wheels, paired with high-strength torsion bar suspension, friction shock absorbers, double-pin ear-hanging glue and tank track plates that can replace floor glue blocks.

The fire control system of the wz1224 test prototype is also very advanced. The comprehensive fire control system with a digital fire control computer as the center data bus as the backbone. It has infrared night combat capabilities. The whole vehicle has three-defense, automatic fire extinguishing and explosion suppression functions, and has hot smoke screen and projectile smoke screen active defense system devices. The whole vehicle has submersible function.

Of course, due to the weak industrial foundation of the Republic, the wz1224 experimental tank also had many unsatisfactory features. For example, the power core of the vehicle was used as an 8v331 civilian diesel engine. Although it could temporarily meet the demand, its size and weight were too large and bloated.

The chassis suspension of the car body is reliable, but the shock absorption performance is far less than that of liquid suspension, and there is almost no potential for future development.

If we add the lack of the top hunting and fire control system for international tank armored vehicles in the 1990s, the wz1224 experimental tank is basically a Chinese simple version of the German Leopard 2a1 tank. (To be continued.)
