Chapter 108 Hot Engine Test Drive!

Time flies.

Before we knew it, the last summer vacation of elementary school had arrived. The June sun was already scorching, casting patches of light and shadow on the ground through the leaves of the trees in the schoolyard.

I don't know if it's because he just finished celebrating his last Children's Day and started to enjoy the perks for teenagers, or if he's just having a lucky summer.

In the past two months, Lin Dong has clearly felt that things have gone much more smoothly and he has a lot more free time.

Under his guidance and with the oversight of Wang Xingguo and Jiao You, the Emei Engine project and the third-generation nickel-based materials have progressed smoothly, bringing him a wealth of experience in large-scale scientific research projects that cannot be learned from books.

The all-new Hot Shot completed all design verifications a week ago, and now all parts have been manufactured and are undergoing final assembly in the final assembly workshop.

"Lin Dong, are you staying home this summer vacation?"

After arriving at school early in the morning and receiving her last family report card for elementary school, Xu Qingling looked up at Lin Dong and asked him a question.

Today she wore a neat ponytail and a blue dress that revealed half of her fair calves. When she looked up, the wisps of hair on her forehead swayed slightly in the summer breeze.

"Yes, I might visit my grandparents and maternal grandparents for a couple of days, but I'll spend most of my time at home."

Lin Dong nodded, looking at the girl who had been following him: "Where are you going for summer vacation? Are you going on a trip with Aunt Zhou?"

"I'm not going on vacation this summer."

Xu Qingling tossed her hair and replied with a smile, "I've been staying home this summer too. My uncle's company's drone pilot game, 'Air Swarm,' launched yesterday, so I'm playing it at home as a brave air force drone commander, but..."

"But what?" Lin Dong said with a smile.

I didn't manage to get an activation code.

Xu Qingling pitifully raised her head: "Yesterday the game released an announcement about its launch, and then the headquarters followed up with an official certification."

The announcement stated that players nationwide who met the age requirements, achieved the required academic standards, and ranked highly would be eligible for a special recruitment program to enter military academies each year… Eight million activation codes were sold out in less than ten minutes.

"I'll get one for you."

Lin Dong smiled, took out his phone, and found his uncle's contact number.

"Big Brother! Brother Lin Dong!"

"Godfather! Godfather Lin Dong!"

Before Lin Dong could make a call, two shouts suddenly rang out behind him.

Zhang Yihao and Li Tao rushed over, grabbing Lin Dong's arms and pleading, "Ask Uncle for more activation codes! We need some too, we didn't manage to get any!"

"..."

Lin Dong pulled his arm away and said speechlessly, "Send over your ID numbers. This game requires real-name registration for login."

"Yes, sir!"

Zhang Yihao and Li Tao immediately shouted and took out their phones to call home to ask for their ID numbers.

[At this point, I hope readers will remember our domain name 1110 ...

"...Never mind, I'll do it."

Seeing the troublesome situation, Lin Dong sent a message to his uncle before the two could even ask for the number.

[Lin Dong]: Uncle, I need a few activation codes for "Sky Flight - Beehive" that aren't linked to an ID card. I want to play the game with my classmates during summer vacation.

[Uncle Zhang Fangxu]: Wait a minute.

[Uncle Zhang Fangxu]: Your uncle Zhang Fangxu has sent you an "activation code" document.

[Uncle Zhang Fangxu]: The document is encrypted. The password is your birthday. You need to enter the activation code and then bind your ID number. You can only play if you are 12 years old or older.

[Lin Dong]: Thank you, Uncle.

Lin Dong sent a thank you message, entered the password to open the document, and immediately, a document with one hundred activation codes popped up.

Wow!

Zhang Yihao and Li Tao were stunned, exclaiming in unison, "Uncle is so generous!"

"Ten for each of you, take them and show off."

Lin Dong wasn't stingy either, sending ten activation codes to Zhang Yihao and Li Tao each.

Then he found the contact information of Zhang Zihua, Huang Qingyao, Su Yue, Xu Hua, Zhang Xuebing, Jiang Caiping, and others, and sent ten messages to each of them.

There are twenty left. Just send them to Xu Qingling and tell him to save one for him.

"Let's go, let's go back and start the war!"

Upon receiving the activation code, Li Tao exclaimed impatiently, "I've decided! This summer, I'm going to be among the top 500 in the country, and when I'm old enough, I'll take the military academy entrance exam and become an elite drone commander!"

"Didn't you say you were going to take the computer exam?"

Zhang Yihao complained from the side, then excitedly added, "I saw someone online say that in addition to individual competition, this game now also features the top 100 cities in the world."

In the future, a space version will be released, along with versions of fixed-wing supersonic fighters and aerospace fighters…

As they spoke, the two waved goodbye to Lin Dong and Xu Qingling and hurried home, clearly eager to start the game.

"The fixed-wing supersonic fighter jets in this game..."

Xu Qingling watched them leave, then turned to look at Lin Dong with a curious expression.

"Yes, that's the plan. We'll transfer the performance model of Hot Spicy to it when the time comes."

Lin Dong nodded and said with a smile, "However, the aerodynamic model for supersonic scenarios is quite complex. Currently, the performance and computing power of computer chips are insufficient to support the calculations of a real engine and simulate supersonic combat scenarios."

However, my dad has already asked my uncle to invest in the semiconductor and computing chip sector, which should take about six or seven years.

Once an object enters supersonic speed, the complexity of its entire aerodynamic structure and the physical properties of the surrounding fluid will increase exponentially.

To enable every player's computer to support such a high level of computing power, current semiconductor chips are still at least a decade or more behind.

Even if he gets his uncle to invest now, this won't be a problem that can be solved in a short time.

"Six or seven years, just like high school and college..."

Xu Qingling did some calculations, then raised her hand and cheered, "I'll study Air Force Operations Command, play games in college, and then keep playing games in college!"

"Commander, we're leaving, we're going back."

Lin Dong patted Xu Qingling on the head, and the two did not return to the Chengdu Aircraft Industry Group's residential compound.

Instead, it was a small assembly workshop located next to Experiment 78, which was assigned to Xu Ziming and was renovated by Xu Ziming alone.

The two walked for more than twenty minutes and arrived at Xu Ziming's final assembly workshop.

As soon as the door opened and I stepped inside, before I could even enter, Xu Ziming's stern voice blared from the loudspeaker next to me.

"Put on full dustproof suits and walk through the dustproof passage. Inside, they're assembling engines; the precision requirements are quite high..."

Lin Dong and Xu Qingling exchanged a glance, then obediently went into the dustproof cubicle, put on full dustproof suits, hats and masks, and then went through the dustproof passage into a small cubicle inside.

Wang Xingguo, Lin Weiliang, and Xu Ziming were gathered around two small engines that had already been largely completed, with a diameter of less than 350mm and a length of 2500mm.

Wang Xingguo was responsible for watching from the left, Lin Weiliang from the right, and Xu Ziming was responsible for final assembly. There was no room for anyone else to interfere.

"Lin Dong..."

Xu Qingling looked at the heat exchanger that was vaguely visible inside the engine's air intake, and then at the large and small pure copper pipes that connected the combustion chamber and the air intake heat exchanger. She couldn't help but ask a question.

"Why is this engine different from the one on the Hot Spicy Ship?"

"The addition of an air intake pre-cooling device and the use of a brand-new heat-absorbing fuel... has significantly improved the engine's limits, making it the world's first hypersonic aircraft engine."

Lin Dong's tone carried a hint of anticipation.

A pair of eyes watched Xu Ziming's assembly movements intently.

It must be said that although Xu Ziming is rather lazy, his skills are truly exceptional; his assembly movements are fluid and effortless.

For some components that require liquid nitrogen cooling or spray gun heating before fitting the fitting wire, there's no need to measure the temperature over time; you can directly use your hands to get the standard temperature.

Although he could control the degree of this more precisely than Xu Ziming by relying on his soul vision, he had after all opened it, and the smoothness and proficiency of his movements were far inferior.

Less than thirty minutes after Lin Dong and his companion entered, the entire internal components of the engine were assembled.

Xu Ziming picked up a casing from the engine and pointed to a long-arm wrench next to Lin Dong: "A long-arm fixed torque wrench, for 48N torque..."

"OK!"

Lin Dong quickly picked up a fixed torque wrench marked 48 Newtons, took two steps forward, and handed it over.

Xu Ziming reached out and took it, quickly and precisely screwing in each screw to protect some sensitive lines and pipes. Then he pulled the rope, attached the buckle, and moved the hydraulically stabilized mobile vehicle that was placed to one side, preparing to move it to the testing area on the other side.

"Weiliang, let's go, let's take the fuel and testing tools to the testing station together."

Seeing this, Wang Xingguo realized that the entire engine assembly was complete, and he excitedly greeted Lin Weiliang.

soon.

With the combined efforts of the three.

The two engines were then mounted on the test bench, connected to an electric starter, and filled with heat-absorbing kerosene, which serves as both coolant and fuel.

"Everyone, go to the side and watch the safety rules."

Xu Ziming glanced at Lin Dong and Xu Qingling, then pulled down the blast door and led the way to the test control room next to it, which was separated by thick safety glass.

Lin Dong nodded without saying anything.

Although he knew there were no problems once the engine assembly was complete, the safety procedures not only protected him but also everyone else. Behind every procedure was a lesson learned in blood.

woo-

The group went to the next room, and Xu Ziming pressed the test button. The engine's starter motor started running, driving the blades to rotate, and a whirlwind immediately swept across the entire test bench.

"Very smooth."

Xu Ziming glanced at Lin Dong, opened the cover in front of and behind the engine to reveal the air duct leading directly to the outside, and the next second, pressed the start button.

hum-

The entire engine vibrated a few times.

In less than two seconds, the sound became perfectly smooth.

The airflow in the entire test chamber flows in orderly from the intake duct, is compressed by the compressor, burns and expands, and is then ejected from the tailpipe.

"……Um?"

Xu Ziming's eyes showed a hint of surprise. He glanced at the various parameters displayed on the screen, turned on the high-power axial fan in the direction of the air intake to simulate the ram air intake state when the engine is flying, and then increased the fuel input.

hum! ! !

The engine's hum suddenly became shrill, and the dust on the test bench began to swirl slowly.

"Ziming, don't try it."

At this moment, Wang Xingguo noticed Xu Ziming's emotions. He didn't call Xu Engineer in private, but couldn't help urging him, "Xiao Dong has never tested this miniaturized engine before. You've already made an exception for him today."

Your environment doesn't meet the requirements for simulating supersonic flight testing. Just check the effectiveness of the RATR's pre-cooling device!

"..."

Xu Ziming's eyes twitched. He turned the axial fan simulating air intake to its maximum, increased the throttle, and then turned on the coordinating switch of the pre-cooling device.

boom!

The two engines roared to life, their exhaust pipes spewing out long plumes of flame.

The next moment, Xu Ziming pressed a switch.

Bang!Bang!

Two jets of azure flame shot out from the axial fan and towards the engine's air intake, instantly heating the air to over a thousand degrees Celsius before it was sucked in by the engine.

This is simulating hypersonic flight, where the air intake compression is increased to thousands of degrees Celsius.

If the RATR precooling unit is functioning properly, the air, which is over a thousand degrees Celsius, will be cooled to tens of degrees Celsius before entering the compressor through the intake duct.

This heat will be absorbed by endothermic kerosene, which will then decompose into methane, hydrogen, and other gases, further improving the engine's combustion efficiency.

"The air intake has cooled down!"

Upon seeing the flames shooting out, Wang Xingguo, Lin Weiliang, and Xu Ziming immediately looked at the readings on the high-precision temperature probe next to them. Wang Xingguo even couldn't help but start calling out the numbers.

「740℃……324℃……129℃……53℃……24℃……24℃！」

hum-

The temperature was fixed at 24℃.

The roaring engine sound suddenly became smooth, and the exhaust flames from the tailpipe shortened considerably.

The color changed from the blue mixed with pale yellow of burning kerosene to the pure sky blue characteristic of burning hydrogen and methane...
