A nation's industrial development begins with junior engineers.

After unpacking the thick packaging, two blades with a radius of 2.8 meters appeared before everyone.

Scanner on!

Watching the blade chord gradually taper from root to tip, Xiao Daimao nodded in satisfaction. "Not bad, not bad." It seems 122 has truly mastered the three-axis machining center; otherwise, they'd have a hard time making something with this gradient design.

The torsion angle is also quite good, just within the design range.

Jiang Xia asked a few people to help install the spinneret.

A small propeller at the tail is connected to a horizontally opposed engine!

Okay, let's adjust the pitch angle again. Since it's a semi-open cockpit now, let's set the angle to 6°. We can adjust it later when we upgrade to a closed cockpit and need to optimize cruise efficiency.

Well, the current universal angle gauges are just too inaccurate. When will we be able to use laser profile measuring instruments? Otherwise, mass production is really a headache.

With the help of Tie Jun, Xiao Dai Mao slowly moved the propeller while operating the scanner.

All set! Now it's time to test it out!

The large-item access road inside the factory has been temporarily closed—well, that's unnecessary. The workers are all diligently working in the workshop; they don't have time to come and see yet another invention by Jiangxia's engineer.

Looking at the thing in front of them that resembled a helicopter, the team members in the classified workshop whispered among themselves.

The old company commander nudged his comrade next to him.

"Six, haven't we seen this thing on the battlefield in the north? You still say it's a new gadget from the Bald Eagles?"

"Yeah, but isn't this one Xiao Jiang made a bit too small? It doesn't seem to be the same as the Bald Eagle one. That helicopter has a rotor blade at the base of its tail, but Xiao Jiang's is on the back..."

"Hey, old company commander, this is nothing! Do you even know where Little Jiang got that propeller blade he's attached to his butt?"

"Did he take apart another machine?"

"Hey! Maybe you're the senior one, because he took apart the electric fan he just made a couple of days ago..."

"what……"

Listening to the crowd's discussion, Jiang Xia held up a finger and shook it: "Stop arguing. Do you think the blades of that fan are that simple? Let me tell you, its maximum airflow is a full 135 m3/min! Don't tell me that this machine only weighs 380 kilograms. Even if you add another 50 kilograms, it's no problem!"

Everyone nodded in agreement. You're right, you've said a lot!

Little Dumb Hair retorted angrily: "Hmph! I'm not telling you, the impeller's aerodynamic parameters of that electric fan are top-notch! Didn't you see the fan blades on our air fryer? They have the same parameters! Do you know that these parameters are the optimized solution we obtained after blowing through countless wind tunnels in later generations?!"

(This is actually true. A certain extravagant air fryer manufacturer actually took their impeller design to a wind tunnel for testing. Wow, even the US would be drooling if they knew. Because testing it in a wind tunnel costs us a small fortune!)

Hold your jaws steady, or you'll be scared out of your wits!

Jiang Xia took the willow helmet from the old company commander's head and, with his rear end sticking out, tried to climb onto the gyroplane.

"Paji..."

The "Wild Geese Descending on the Sand" pose involves turning your buttocks backward.

"Old Wang! What are you doing?!"

"Yeah, we did it, so what?" Old Wang glanced contemptuously at Little Dumb Hair. "Old Company Commander, hold this kid down! He sneaked off to Old Man An-2 last time, and he thinks he can do it again? Dream on!"

Despite their injuries, the old company commander and Liu Zi used a powerful downward thrust to firmly pin Xiao Dai Mao down beneath them.

Completely ignoring what the little brat was yelling about: the gyroplane is incredibly safe, even if the engine stops, it can still slowly float down like a bamboo dragonfly.

Ha, whatever you say, I'm not letting you! Who knows if it'll float down or crash down. Let that rough guy Wang Kui handle the dangerous stuff.

The old company commander calmly restrained the little idiot, letting him bounce around on the ground like a salted fish.

"Stop, stop, stop!" Jiang Xia suddenly noticed something, lay on the ground, and waved his hands frantically.

Seeing that no one listened to him and they were just circling around the brand-new gyroplane and Old Wang who was about to start the machine, Jiang Xia was terrified.

"Old Wang, takeoff paused! This flying cat car forgot to put wheels on!"

……

"What should we do! This is the smallest tire we have... Should we just make do with it?"

Old Wang drove the little jeep over, pointing at its wheels with some reluctance.

Jiang Xia grumbled and grumbled, so focused on checking the mechanical structure that he forgot about the small wheels of the gyroplane. You know, this thing is not like a helicopter; it still needs a runway to take off and land. It only needs to be 20-30 meters long. But the problem is, we don't have rubber tires that small right now!

Tsk tsk, they've gotten too cocky. They didn't even use a scanner to test build the blueprints.

Jiang Xia slapped his forehead in frustration: "Don't count on these tires. The takeoff weight is at most 800 kilograms. With these tires added, whether it can even take off is another matter..."

"Forget it, let's just have the tire factory make a few smaller tires first!"

Everyone let out a regretful "Oh," and prepared to push the machine back into the workshop.

"Little Jiang, I have tires!"

"Ok?"

Everyone turned around and saw a young man in a leather jacket waving with a smile.

"Pang Guoxing? Hey! What brings you here, kid!"

Old Wang laughed heartily, stretched out his hands, and went to meet him.

Pang Guoxing was overjoyed: "Hey! They've already gone to Chengdu to test the modified..."

"Hey, hey, hey. Why did you just start using your hands?"

"Where's the tire? Where's the tire?! Where's it hidden...?"

It turned out that after Lao Wang approached Pang Guoxing, he hugged him tightly and then began to grope Pang Guoxing's body.

While dodging the wicked hands of Old Wang, Pang Guoxing angrily retorted, "Are you stupid! Even if it's small, do you think I can carry a wheel around with me?!"

After the initial excitement, Pang Guoxing finally began searching through the large bag on his back.

"Hehehe, Little Jiang, I was planning to take this home and make a little wheeled car for my nephew..."

Looking at the dark wheels, which were only 350 millimeters in diameter, Lao Wang wanted to snatch them, but Pang Guoxing dodged past him and handed them to him in Jiangxia.

"Young Jiang, what do you think of this thing?"

Jiang Xia held the wheel, looked at the FR-SA316 on the rim, his lips twitched, and bounced it a couple of times like a ball. Wow, that's impressive! France's industrial strength is truly amazing now!

"You shot down another plane?"

"Hmm, no big deal. The Lark III was flying over to Tibet to test your abandoned turbocharger when it ran into us, and one big shot took it down..."

"Wow! Congratulations! Another star on the plane?"

"Half a shell! And the commander scolded me, saying I was wasting it, that I should have used the aircraft cannon..."

"Tsk, you'd have a hard time shooting it down with an aircraft cannon. Even the J-6A's low-speed performance isn't great..."

"Hey hey hey..."

Seeing that Jiang Xia was chatting happily with the young man who had just arrived, the crowd wisely expanded the circle of onlookers several times over.

"Xiao Jiang is a good person, but he always has a sharp tongue..."

The old company commander touched the booklet that Secretary Liu had brought him, looking quite annoyed.
