Although the test run has just begun, and it is far from the time to say success, but such a complex equipment can reach this point to show that it has succeeded 80 percent, even if it fails later, it is only a failure in details, which can be modified and improved.

According to the test procedure, fifteen minutes later, Wang Xian ordered loudly: "Start loading, load fifty percent!"

The female tester replied loudly: "Yes! Start loading, load 50 percent!"

Loading, as the name suggests, is to add a load (load) to the engine. The engine on the test bench is connected to a flexible load.

The flexible load, on the other hand, is provided by a large torque converter and a generator. Torque converters can change the torque by changing the amount of oil in the turbine, while generators can change the load by changing the output current.

The so-called 50 percent loading is to add about 900 horsepower to a 1800 horsepower diesel engine.

After a few minutes of operation, it was time to report on the operation, and a woman and a man reported loudly again:

"Rotational speed is normal!"

"Fuel consumption is normal!"

"Noise is normal!"

……

Listening to this, the two military representatives were not calm anymore, and involuntarily glanced at each other......

The reason why the military representatives are not calm is because half of the rated power of an 1800-horsepower diesel engine has 900 horsepower, which means that the current power is enough to bring a light tank to gallop on the battlefield!

You must know that the engine power of Huaxia's current main tank is only 1200 horsepower.

Even if the engine in front of me can't reach the designed 1800 horsepower, it can be used as long as it exceeds half the power.

In short, so far, it can be described in two words: there is a play!

Large-scale engine verification test is a total verification of its design, manufacturing process, materials and other aspects, only the engine test is normal, it means that the engine design, manufacturing process, materials and other aspects are no problem.

Only when the engine fails to test and there is a problem, it is necessary to conduct a thorough analysis of the problem, find out the cause, find some defects and problems in the design, find some problems in the selection of materials or some problems in the manufacturing process of parts.

Because it was the first test run, the time of each test process was not long, and soon, under the order of Wang Xin, the commander of the on-site test run, 75% of the power was tested half an hour later.

Half an hour later, 75 percent of the load loading test was successful!

After another half an hour of test drive, Wang Xian glanced at Jiang Xinwei and Zhang Huan, and when he saw the two nodding in unison, he ordered loudly: "Rated power loading test!"

The eyes of the two military deputies lit up, and their gazes instantly fell on several computer screens.

Hearing the command, the test driver once again controlled the throttle on the computer to increase the amount of fuel. The engine immediately accelerated, and a strong but steady sound slowly sounded in everyone's ears, and there was a noticeable vibration on the ground.

Although there is bulletproof glass between the monitoring control room and the test frame to isolate the sound, the distance between the two is so close that both sound and vibration are inevitably transmitted in.

A series of sensors monitor the status of the engine, and several computer displays display various parameters. With the increase of engine input oil, the data of the engine working state begins to climb rapidly, such as the engine speed, output power, fuel consumption, body temperature and other data continue to increase.

Everything is working fine, the screen is green!

Everyone waited silently, and the entire monitoring and control room became quiet, until it was time for the test driver to report the results, and the silence here was broken:

"The rated power speed is normal!"

"Fuel consumption at rated power is normal!"

"The rated power noise is normal!"

"Rated power exhaust emissions are normal!"

"The temperature rise of the rated power is normal!"

……

The reason why the words "rated power" are added before each indicator is normal is because these four words indicate that this diesel engine fully meets the design requirements.

It also indicates that the 1800 horsepower diesel engine has been successfully developed!

At this time, Wang Xian asked Zhang Huan: "Mr. Zhang, do you want to increase the load for testing?"

Jiang Xinwei did not answer directly, but asked Kaloshov: "Mr. Kaloshov, what do you see? Can the cylinder and casing withstand such a heavy load?"

After all, this engine was improved on the research and development of the former Soviet Union, and whether the main components can accept the operation of excess power, Kaloshov, who has participated in the development of this engine from the beginning, has the greatest say.

Kaloshov nodded and said: "The temperature rise is normal, the noise is normal, I think it can be added." As he spoke, he turned to Jiang Xinwei and asked, "Jiang Dong, what do you think?"

Jiang Xinwei knew that this guy had been in Huaxia for a long time and had learned these false etiquette, so he smiled and said, "I trust your judgment, add it." If something goes wrong, the responsibility is not yours, I will bear it. ”

Zhang Huan suggested to Jiang Xinwei: "Since this is the case, then it will be up to you Jiang Dong to announce it, how about it?"

Jiang Xinwei did not postpone it, and shouted loudly: "Twenty percent of the load is running overload!"

Hearing his voice, the military representative's eyes widened and his heart pounded: As long as the next step is successful, doesn't it mean that our Huaxia military has the world's most powerful tank heart?

All the people were silent, all eyes were glued to the computer monitors, looking at the data.

The noise in the monitoring room is getting louder, the ground vibration is getting louder and louder, and the engine power is climbing rapidly: 1800 hp, 1850 hp, 1900 hp, 1950 hp, 1800 hp, 2050 hp, 2100 hp......

It wasn't until the power reached 2,140 hp, or 120% of the rated power, that the engine's output finally stopped climbing. Because it is operated beyond the rated power of the engine, the damage to the engine is great.

It is not often that the tank is forced to use such a high power in practical use, unless the tank encounters a critical situation and has to flee for its life. So, the experts only used this power for ten minutes, and soon the power began to drop and returned to the rated power of 1800 horsepower.

The engine on the test bench is like a horse, from the restless and violent state just now to docile and leisurely.

As the data became more and more normal, everyone knew that the test was perfect, and the design calibration and finalization of this engine were just around the corner.

After running continuously for half an hour, it has been normal, and according to the test procedures, the test driver closed the accelerator and stopped.

Everyone breathed a sigh of relief and was elated.

Kaloshov shouted happily: "Gentlemen, we have a successful test drive, shouldn't we have a drink?"
