The same one thousand horsepower diesel engine feels different from the one thousand horsepower diesel engine of the Oriental Power. Although this level of two-stroke diesel engine has reached its horsepower, its torque is not high.
Many people like to look at horsepower when comparing the power of the engine. They often think that the amount of horsepower is as good as the sky. In fact, horsepower is related to the speed. Only when the accelerator is stepped on to the bottom and the engine speed reaches its highest speed.
Horsepower is the largest. Although there is a two hundred horsepower engine stuffed into the front of the car, I am reluctant to step on the accelerator, but in fact, the power is only exerted by twenty horsepower.
Horsepower is obtained at the highest speed, so it determines the vehicle's extreme speed ability. How fast a car can eventually run depends on how much horsepower it has. For tanks, the same is true, with a thousand horsepower,
It can make the tank reach an extreme speed of more than 70 kilometers per hour, but with a 500 horsepower, the tank can only be driven to 50 kilometers per hour at most.
What really determines the speed of the tank is torque. The characteristic of the turbocharged engine is to allow the torque to arrive earlier, so that the vehicle will speed up more rapidly. Of course, the disadvantage is that when the turbo power comes up, you will feel it.
Suddenly, the sales of car sales will explain it as a pushback feeling. In fact, many turbocharged models are criticized? It is the sudden acceleration brought by this turbine when it exerts force, and the smoothness and self-priming engine are not there.
Fabi's.
For tanks, if you want to squeeze potential, you have to rely on this supercharger? The horizontal opposing engine is no exception? However, the unique structure of this horizontal opposing engine determines its insufficient torque.
Even the later 1200-horsepower 6TD-2 diesel engine has a torque of only 3200 Nm? This data is even worse than the torque of the 780-horsepower diesel engine in the T-72 tank.
This is actually a helpless choice. A horizontally opposed engine? There are two pistons in a cylinder? It moves to both sides at the same time? So? Its cylinder is very long? If the connecting rod is also lengthened, it will cause the overall size of the engine to be too large.
, cannot meet the requirements.
For the engine, the longer the connecting rod, the greater the torque. This is the most basic physics principle? In order to stuff it into the narrow engine compartment, this engine has made a lot of compromises. Speed up? It's slower
Half beat? At the same time, it is estimated that there is also a gearbox relationship. In short, the overall power system is not very useful.
Therefore, it is reflected in speeding up, so it will be half a beat slower. Wang Erzhu's foot has already stepped on the accelerator to the bottom, and black smoke is coming out from the tail. The tank is moving forward in a loud voice. Then, it has been hung in the second gear and continues to speed up.
, third gear, fourth gear.
The tank started to move in the test yard, and streams of black smoke came out, and the tank was jogging and moving forward.
Wang Xiaoyu placed his eyes on the sight and looked at the view inside. Although the tank was bumping, the image inside remained motionless. From the perspective of the fire control system, it was still doing well.
The laser rangefinder began to emit infrared rays and headed towards the target in the distance. Although it was the first time to contact, Wang Xiaoyu could skillfully operate the tank's fire control system. Her face was full of seriousness and concentration.
, start preparing before shooting.
"The coach plays one and reloads."
With the slogan, the automatic loading machine moved. The two of them were on the left and right. The inside was quite narrow. The automatic loading machine in the middle started to move with a clatter.
The main component of this automatic loader is the lifting arm. Its main principle is the "two-stage crank slider" mechanism, the elastic body is fixed to the rocker arm, and the cartridge acts as an intermediate connecting rod. This will achieve the space position
movement.
Qin Zhenhua looked at the automatic loader beside him, and he felt a little nervous. This is not an automatic door in later generations, and it can be anti-pinched. If he accidentally reaches into this mechanism, it will suddenly lead to a tragedy.
He looked at his wife with concern and confirmed that she was fine, then he focused on the automatic loader again. He saw that the elastic arm was rotating around a horizontal axis, and the "four-wheel car" mechanism at the front end was stuck in.
Below the horizontal magazine with the articulated segmented magazine, the lifting arm completes the fixed connection with the horizontal magazine, forming a "crank slider mechanism".
Then the lifting arm continues to rotate, and finally completes the movement of the warhead and cartridge. Now, the L-shaped warhead and cartridge have become horizontal. The lifting arm lifts the shell to the back of the barrel, with the warhead in front and fired.
The cartridge was behind, followed by the pushing rod, pushing the entire barrel into the cannon chamber.
At this time, the cannon was in place.
Different from the two pushes of the T-72, if compared, this design can theoretically increase the rate of fire. After all, when the T-64 was developed, the Soviet army put forward high technical requirements.
.
However, in terms of reliability, Qin Zhenhua still likes his two bullet pushes, and the mechanisms are parallel, which is more convenient. Now, this kind of thing has to be discounted once in the middle.
However, the people who designed this organization also took a lot of effort.
"The target has been targeted."
"Open fire!"
"boom!"
At this moment, the entire tank body was shaking due to recoil. If it was the first time sitting in the tank, it would definitely be scared to death. This kind of movement was like a landslide and cracking.
Wang Xiaoyu was very natural. She had long been accustomed to this kind of movement. Her eyes were always staring in the sight, looking at the trajectory of the shells. This kind of coach shot through a clear trajectory in flight.
, hit the predetermined target.
Had it?
Seeing this scene, Du Laba behind him also sighed. He did not give any explanation. The other party was a woman. After going up, she thought she was just enjoying her pleasure. Who would have thought that she had real skills and could hit her with just one shot.
The goal is here!
Of course he didn't know that when the Eastern power transformed the T-72 tank for the oil country, Wang Xiaoyu had long tried it on it, although the fire control system models of the T-72 and T-80 were not the same.
But that's similar.
One shot hit the target, and then the second shot.
Compared with the first firing, it has one more step to get the shell.
The T-72's shell is thrown directly outside the turret and litters, while the T-80 has an extra recycling process. When the second shell comes up, the empty shell is just placed in the empty bucket.
.
Wang Xiaoyu aimed steadily at the target, and then fired a second shot.
