Chapter 349 Looking at each other, a thousand years at a glance! (add 23 for Murray Snow)

In the static test area, the classic tractor that has been brewing for a long time is quietly parked in the center, with a conventional body layout, a design with two front tires and four rear tires, a single-cylinder diesel engine painted with Chinese red to exude atmosphere, and a red five-pointed star dotted it , [-]-watt incandescent headlights are installed on the front, and the rear is a boxy cargo box with a stepped design to obtain the maximum space in the rear row.

The exterior of the classic tractor is perfect, but its interior, whether it is the high-torque and high-speed transmission ratio system that surpasses the concept of the times, or the military-grade beam and half-shaft, are all born for load.

The most important thing is that the rear axle suspension system uses a full fourteen layers of leaf springs, and the ultimate load is almost [-] tons.

After so many days of hard work, after building the first single-cylinder diesel engine, Yu Hua and Zhuang Qianding finally completed the manufacture and assembly of the prototype of the Red Star tractor.

Now, the static test link has all ended, and it is time to come to the final dynamic test link.

Through the dynamic test, the success of the Red Star tractor project can be declared and it will enter mass production.

As for whether this method seems a little child's play, it can only be said that everything was done quickly during the war.

Following an order from Yu Hua, the chief engineer of the project, the young driver who had obtained the best results and driving qualifications after special training and assessment quickly stepped forward, opened the fuel tank to fill up diesel, and then filled the water tank with water after the fuel was filled.

Oil, add water, put eggs.

This is a characteristic of the 90s. Before the tractor leaves the vehicle, put an egg at the mouth of the water tank, and it will be cooked after a while. You can eat hot boiled eggs anytime, anywhere.

Outside the safe area, Professor Zhuang Qianding stood in the first row, with a smile on his face, staring at the Red Star tractor, which was undergoing final preparations before the dynamic test, with anticipation in his eyes.

All is ready except for the opportunity.

After so much preparation and busy work, the last moment finally ushered in.

Standing next to them are the heads of various departments of the Military Industry Bureau, as well as General Liu who was invited to visit as a representative of the army. If the Red Star tractor has excellent load and off-road performance, this tractor will be installed in the army immediately.

"Report to the chief engineer, the oil and water have been filled, please give instructions!" After the busy work was over, the young driver from the security regiment of the headquarters completed all the preparation procedures, ran to stop in front of Yu Hua quickly, stood at attention and saluted, and reported in a serious voice .

"Start the experiment." Yu Hua nodded and said.

"Yes!"

The young driver responded loudly, straightened his back, and turned to meet the Red Star tractor behind him.

Yu Hua then glanced at Lin Wan on the right, signaling to back away. Afterwards, the two left the parking space and backed out of the safe area.

At this time, the audience was silent.

At this moment, everyone is watching.

All eyes are focused on the Red Star tractor, and the eyes are radiating light, all of which are shining with colors that symbolize hope. For Western countries, manufacturing tractors, a simple power machine, is as simple as eating and drinking. But for China, For the base area, this is an unprecedented challenge.

The significance of Red Star Tractor's success is not only to solve the problem of insufficient transport capacity in the base area, but also means that the Chinese have independently built their own power machinery since then!

This is one small step for the base area, but also one giant leap for China.

In the arena, the young driver, who was the focus of the audience, took out a crank handle weighing more than a catty, and then went to the front of the car and put it into the starting port connected to the crankshaft of the engine.

The whole person adjusted the damper with his left hand, held the metal crank tightly with his right hand, and then exerted force all over his body. After seven or eight consecutive turns, the sound of the mechanical operation became louder and louder, and there was a low and powerful sound of the engine running.

"Thu, chug..." The sound of the normal operation of the single-cylinder diesel engine resounded through the open space and spread throughout the audience.

The cold start was successful. The young driver put away the heavyweight key and waited quietly for the engine temperature to rise. This is the warm-up link.

"Jinyu, are you nervous?" Yu Hua looked at the field with both eyes, turned to look at Lin Wan, and asked with a smile.

"Nervous, afraid of problems, afraid of tractor failure..." Lin Wan breathed slightly solemnly, nodded in response, and did not hide the various emotions in her heart.

nervous?
Of course nervous.

She deeply understands the meaning of this ugly big guy in front of her. If the dynamic test fails, it means that everyone's hard work for so long is in vain, and they need to start all over again.

"We will succeed, and failure will not change anything." Yu Hua blinked, smiling, and his words revealed strong confidence.

Regardless of whether this test fails or not, it will not affect the final success of the Red Star Tractor.

This is Yu Hua's self-confidence.

Hearing Yu Hua's words, Lin Wan was stunned for a moment, then smiled lightly, already understood what Yu Hua meant, and looked at the Red Star tractor in the test area no longer so worried.

After 5 minutes, the warm-up session ended, and the young driver quickly sat in the driving seat, stepped on the brake, held the handle with his left hand and squeezed the clutch tightly, and held the gear lever with his right hand to shift gears.

First gear, step on the accelerator, release the clutch.

In an instant, the energy generated by the operation of the diesel engine was rapidly amplified through the transmission system, and the power was transmitted through the drive shaft to the wheels. After a few seconds, under the gaze of everyone, the Red Star tractor in an unloaded state started to move slowly.

"It's moving! It's moving!" Someone in the crowd immediately shouted excitedly.

In an instant, applause like a tide was sent immediately, resounding through the audience.

Everyone applauded unanimously.

Looking at the slow-moving Red Star tractor, General Liu's eyes lit up, as if seeing a peerless beauty, and he couldn't look away.

Majestic, majestic, and solemn, the Red Star tractor, which runs smoothly at a speed of five kilometers per hour, is like the bright and dazzling stars in the night sky, with infinite appeal.

What is love at first sight?
This is.

For General Liu, high-end gadgets like tanks and armored vehicles are too far away, but the Red Star tractor in front of him is extremely real, and it is not an exaggeration to describe it as "between looking at each other, looking at a thousand years".

This is his dream machine.

Yu Hua and Professor Zhuang Qianding applauded enthusiastically, looked at each other, nodded and smiled.

Looking at this scene, Lin Wan breathed a sigh of relief.

"Huh..." The applause was like a wave. Hearing the applause from the observation area, the young driver Tao Fang did not dare to be distracted. Drive out of the parking area along the prescribed route, and come to a circular driveway similar to a playground runway, and start preparing for the first speed test.

Due to the simple conditions, the content of the dynamic test is naturally not as strict and cumbersome as the later generations. It mainly tests vehicle speed, braking distance, fuel consumption, passability and load.

Sorry, there are none of the test contents such as the [-]-kilometer reliability project and durability project.

"Thu, chug!" Step on the accelerator to increase the speed, the sound of the engine running suddenly increased, and the speed of the car suddenly increased. When the speed reached about eight or nine kilometers per hour, Tao Fang immediately released the accelerator, pulled the clutch with his left hand, and shifted into second gear with his right.

Shift into gear and hit the gas pedal.

The operation is quick and fast, just like an old driver.

accelerate!
accelerate!
accelerate!
The speed of the vehicle continued to increase. Tao Fang, who was operating the actual vehicle, had returned to normal after the initial nervousness. He continued to operate back and forth, and steadily controlled the tractor to gallop along the 600-meter circular driveway.

At the same time, the vehicle speed detection work in the test field is being carried out simultaneously to obtain the driving speed of the prototype vehicle in real time.

The detection method is very simple. Use a stopwatch to record the time spent per lap, and divide the distance by the time to get the vehicle speed.

"What's the speed now?" Yu Hua shouted to the timer holding the stopwatch when the prototype car passed the monitoring point again.

The timekeeper responded quickly: "Report, about [-] meters per second."

"Eight meters five per second is equal to thirty kilometers per hour, which has reached the design level." Yu Hua nodded after hearing this, and immediately realized the speed in his mind.

Thirty kilometers per hour was the design standard for Hongxing tractors at the time. Don’t think that this speed is very low. In 1937, in China where the average train speed was [-] kilometers per hour, this was the real "high speed" standard.

Soon, the speed test was over, and the results showed that the Hongxing tractor could reach a top speed of [-] kilometers per hour under no-load conditions, and it was passed.

After passing the speed test, the Red Star tractor continued a series of subsequent tests in the proving ground.

Braking distance: 6.5 kilometers per hour, [-] meters.

Passability: The maximum climbing is 40 degrees, the maximum wading depth is half a meter, the cross-country speed is 5-15 kilometers per hour, and the terrain such as sandy land, mud pits, steps, steep slopes and slippery roads has a certain ability to pass through, but does not have the ability to pass through swampy terrain .

Fuel consumption: 12 liters per [-] kilometers...

The dynamic test project continues to go on, and various real vehicle data appear, which is surprising and exciting. As time goes by, the entire dynamic test is coming to an end, and we come to the last project - load.

How much can the Red Star tractor pull and run!

This is everyone's biggest concern.
