A nation's industrial development begins with junior engineers.

Chapter 898 The only one capable of commanding the HE submarine's father is probably that idiot

The underwater beam of light flickered a few times before stopping near the stern propeller.

After about ten seconds, the rope suddenly tugged slightly. Then, Teacher Shi Lu's head popped out of the water. He wiped the seawater and mud off his face, his voice hoarse from choking on water: "The shaft seal is a double rubber ring! There are guide grooves at the blade roots! Quick, write this down!"

Jiang Xia immediately took out his notebook and pencil from his pocket, while Chief Engineer Zheng took the safety rope from his hand.

Actually, General Manager Zheng had wanted to take over the rope-pulling job from Jiang Xia for a long time: "You old Peng, are you stupid? You already said you have a grudge against this kid's father, why did you hand the safety rope to him?"

If that young bastard gets carried away and acts impulsively, you'll be crying your eyes out!

Jiang Xia was unaware that Chief Engineer Zheng had a lot on his mind; he was focused solely on taking notes.

Just then, Mr. Lu, the underwater taxi driver, added, "The channel line is a bit strange; it's not straight!"

"Which side? The underside of the blade or the leaf basin?" Jiang Xia immediately shouted underwater, "Are there any patterns in the depth and width of the channel? At the junction of the hub and the blade, is there any special 'corner filling' treatment in the transition zone?"

Upon hearing the question posed from above, Mr. Lu, the underwater taxi driver, was visibly taken aback. A glint of surprise flashed in his eyes amidst the murky seawater.

"Good lad! You have a sharp eye! I'll investigate right away!"

"Damn it, how can this kid ask so many questions! Just like his dad when he was nitpicking..."

Teacher Shi Lu gritted his teeth, gripping the waterproof flashlight tightly in his hand, the beam of light struggling to move between the curved propeller blades.

After a while, his trembling voice came intermittently:

"On...on the back of the leaf!"

“Depth… from root to tip it seems… it seems to be getting shallower! Connection… gurgle…” Teacher Shi Lu suddenly plunged down again.

Bubbles rose from his lips as he stared intently at the blurry shadowy area at the base of the propeller hub. After a few seconds, he popped his head up and shouted, "Yes! There's a large, rounded transition! I can't see it clearly!"

"Okay! I understand! Now, could you please check if the blade's side angle exceeds 30 degrees? Also, is there a noticeable thickening design near the tip of the blade airfoil? In addition, does the guide channel connect to the pressure relief hole at the root?"

"Uh... the tilt angle can only be estimated visually! An estimated 30! The rest..."

"It's...on the underside of the leaf! The groove is deep...it seems to change from the leaf base to the tip! The connection point...gurgle...I can't see clearly, let me feel it again!"

With that, Teacher Shi Lu took a deep breath and plunged back into the water.

"No, I can't see it from here! Give me a hand, I need to get a different angle to see the connection between the drive shaft and the propeller hub!"

Following his momentum, Chief Engineer Zheng and Zhao Gang slowly pulled the rope up a little. Teacher Shi Lu adjusted his posture and plunged into the water again. The flashlight beam circled underwater and then stopped at the connection between the drive shaft and the hull.

……

Chief Engineer Zheng stood by the railing, looking at the swaying beam of light underwater. He shook his head helplessly, but couldn't help but sigh to Jiang Xia and Zhao Gang, "This guy is almost forty years old, but he works harder than a young man. Back when he was still at the coking plant, he dared to hold a steel rod and guard the furnace all day long. He still has this reckless spirit now."

Looking at the tension transmitted through the rope, Zhao Gang sincerely admired him: "This is a true expert! He can endure any hardship and take any risk when it comes to developing technology!"

Jiang Xia's hands, gripping the pencil, were sweating.

Because underwater taxi driver Mr. Lu was constantly adjusting his position, sometimes surfacing to report data, and sometimes diving back into the water to check things carefully, the tension of the rope was sometimes loose and sometimes tight, and every pull affected the hearts of the people on the shore.

Looking at the stubbornly flickering flashlight beam underwater, Jiang Xia suddenly felt a strong sense of resonance.

Wasn't it this sense of urgency that made it so that these predecessors could build up the nation's submarine program bit by bit from scratch, thanks to their dedication to technology?

Do you think that the silly kid is deliberately messing with others because of Shi Lu's comment about having a grudge?

wrong……

This was just a matter of going with the flow...

……

More than ten minutes later...

"You little brat, is there anything I haven't considered?" the underwater taxi driver, Mr. Lu, finally shouted.

"That's all for now. We can see the specifics when the tide goes out! This is enough for our preliminary analysis!" Jiang Xia quickly replied.

"Okay! Pull me up!"

Zhao Gang and Chief Engineer Zheng quickly exerted their strength, and Jiang Xia, with the notebook in his mouth, also lent a hand. Together, the three of them pulled Teacher Shi Lu out of the muddy mixture.

In June, the sea temperature in Dalian at night is only around 16°C, and the water in the dock is even colder because it is not exposed to sunlight.

As soon as Teacher Shi Lu got ashore, he was shivering all over. His lips were purple, his work clothes were soaked and clung to his body, and his trousers and shoes were filled with dark brown mud, making a squelching sound with every step. Water dripping from his hair mixed with mud, leaving mud streaks on his face, making him look like a mud figure just pulled out of a mud pit.

However, his eyes were frighteningly bright. He stared at Jiang Xia intently for a while before forcing a smile that looked more like a grimace: "You little... brat... your question is... really damn tricky! You have... you have that same tenacious spirit as your father back in the day! Like father, like son!"

"Go back inside and warm up first!" Chief Engineer Zheng quickly took off his work clothes and wrapped them around him. "The rest of the work isn't urgent!"

Jiang Xia was a little embarrassed by the praise and quickly handed over the recorded data.

After Teacher Shi Lu had recovered a bit, Jiang Xia, concerned about the equipment inside the submarine, said, "Teacher Shi Lu, you should rest well. I still need to go to the control tower to confirm something."

"Task?"

"Mmm!" Jiang Xia took out a small wine flask from his bag and poured two sips of wine for Teacher Shi Lu. Then he immediately put the flask back.

It wasn't that he couldn't bear to part with the wine, but rather with the wine jug. It was a gift from Old Wang.

The silly boy doesn't have the habit of using borrowed flowers to present to Buddha.

This action seemed to have struck a chord with Teacher Shi Lu, who exclaimed, "So alike! So damn alike! That stingy stinginess is exactly the same!"

Oh no, is this old man bringing up his grudge against my dad again?

Thinking of this, the silly boy slipped away, grabbed the long-legged Zhao Gang, and prepared to leave.

"Hey kid, why are you in such a hurry! What kind of mission do you have?"

"It might be related to sonar."

Watching Jiang Xia disappear quickly, Teacher Shi Lu chuckled and scolded, but still couldn't help but remind him: "That's perfect! Comrade Yang Shi'e from Harbin Military Engineering Institute is currently inside sorting out the internal passages and structure. The entrance over the command tower should have been cleared by now. Go find him; he'll definitely be able to help!"

"Okay! Thank you, Professor Shih-Lu..."

Watching Jiang Xia and Zhao Gang walk away towards the submarine, Chief Engineer Zheng nudged Sergeant Lu beside him with his elbow and whispered, "Hey, Lao Peng, weren't you just yelling that you had a grudge against someone's father? But judging from your posture, it doesn't seem like it."

Teacher Shi Lu stared at Jiang Xia's retreating figure, his gaze complex. After a few seconds of silence, he clicked his tongue and murmured with a hint of reminiscence, "There's a grudge... how could there not be? His father's little bamboo stick really hurt when it hit my palm..."

"what?"

“Old Zheng, I’m different from you guys. I didn’t go to school properly until I was twenty…”

“It was his father who taught me to write, word by word… If I wrote it wrong, he would whip me… He kept whipping me until I was good enough to study in Moscow. This 'grudge' is huge…”

"Hey! You're still as awkward as ever! I thought you had some real grudge against someone! I was just being wary..."

"There's nothing I can do; the temper I developed in prison is something I can't change..."

Teacher Shi Lu chuckled self-deprecatingly, lay back on the ground, and silently gazed at the night sky through the makeshift camouflage cloth.

"Brother Chuntian...Mother Jiang..."

"I miss you all so much..."

Teacher Shi Lu suddenly sat up and looked at Jiang Xia, who was climbing onto the submarine: "Hey? I've run into your son. Do you think he can get away with this?"

"Hehehe, if you don't show up soon, I'll snatch your son and raise him myself!"
