On a wide flat ground, an airplane stood alone, and next to it was an engineer who climbed up and down.

"How?" A middle-aged man spoke excitedly.

"There shouldn't be any problems." A man wearing glasses next to him kept checking it with a notebook, "I think I can arrange someone to test the flight." ”

"Really?" The middle-aged man became more and more excited.

"Yes, Chief Lin." The man with glasses smiled, "This plane, the people of our research institute have been studying it for some time according to the drawings given by the independent division, although it is the first time it has been manufactured, I believe that it can be tested and flowned!" ”

"Okay, I'll arrange it right away! Tomorrow is the time! ”

"Well, as long as the weather is good tomorrow."

"Good!"

The man with glasses squinted slightly, he didn't expect that the information given by the independent division was so complete, and this plane, theoretically speaking, had a range of more than 5,000 kilometers and a maximum flight speed of 700 kilometers per hour.

Especially the engine!

The most direct influencing factor of the quality of an aircraft is the quality of the engine.

Holding the pen tightly in one hand, holding the notebook in the other hand, his eyes staring at the data recorded in the notebook, there was silence for a while.

……

"It's all the data and all the details of the engine!" In the darkness of the night, a voice rang out, "You take this, you must return it to the empire safely!" ”

"Hey!"

……

A few days later, still on the empty ground, many people looked at the plane with excitement in their eyes. This was the first experimental creation of an aircraft by their joint research institute, which took more than a year. Now that the test flight is about to be carried out, naturally everyone is extremely concerned.

"Zhang Gong, is it okay?"

"That's it."

"Okay." The middle-aged man suppressed the excitement in his heart and nodded to the soldier next to him, so the soldier next to him kept waving the flag in his hand, signaling that the pilot who had already boarded the plane could take a test flight.

In the cabin, a young pilot nodded, and then began to operate.

The plane began to taxi forward, and after some distance, the plane began to climb and the landing gear was retracted, slowly getting higher and higher, and the speed was getting faster and faster.

"Oh!"

"It's flying!"

"Go up! Go up! ”

On the ground, the people who were watching cried with joy! God knows how much they paid! Even if there is information!

This aircraft, starting from the engine, to the shell of the aircraft, every screw, they did it personally! The engine alone was studied for more than a year.

And the pilots on the plane, too, breathe a sigh of relief, for now, there are no problems with this plane.

You know, test flight is a dangerous job.

And there are not a few items to be evaluated. Including maximum speed, minimum speed, climb, range, flight time, ceiling, maneuvering flight and take-off and landing performance and other tests. Tests were carried out at a wide range of altitudes and speeds.

……

"Wait, what's going on?"

"Disintegrated!"

"Be careful!"

On the ground, people opened their mouths and watched the plane that had been injected with their countless efforts, disintegrating in the air, and they were all flustered. There was no joy at all.

"Zhang Gong?"

"I don't know...... You have to recalculate it carefully, and save people first! The man with the glasses spoke heavily, but there was joy in his heart, which should be the problem I didn't point out before!

……

In the Northeast, there is still heavy snowfall. Zhou Weiguo hasn't been out for several days. These days, he is waiting for the routine of that Kusashi Mizuno Osa to become regular. Moreover, this heavy snowfall, the temperature outside is more than ten or twenty degrees below zero, and it is impossible to stay for a long time.

"This weather ......," Zhou Weiguo shook his head, "It's too much." ”

"There's no way, it's winter, that's it." Lian Ziwen said indifferently, "We can only do the preliminary work well, and then wait for the people to come, and then carry out the work." ”

"That's all it can be." Zhou Weiguo nodded, last night, he received news from Liu Yuan's side, saying that the first plane of the Joint Research Institute disintegrated in the air after the test flight, which made him not in a very good mood. It stands to reason that the information he gave for many things is relatively complete, and the probability of successful test flights after the aircraft is produced should be very high, but it is ......

"You don't seem to be in a good mood today?" Lian Ziwen looked at Zhou Weiguo, he is also middle-aged, and he is still relatively sensitive in dealing with people.

Zhou Weiguo sighed and spoke, "More than a year ago, a joint research institute was established in Shaanxi, Gansu and Ningbo, and the joint research institute, as the name suggests, is that there are people from both the Kuomintang and the Communist Party, including many top scientists in the world!" ”

"Something's wrong?"

"Well, the first plane that was built in trial was disintegrated during the test flight." Zhou Weiguo rubbed his eyebrows.

"Do the Japanese know about this?"

"What?"

"Do the Japanese know that there is such a research institute?"

"Yes." Zhou Weiguo nodded, "The Japanese are almost pervasive in their infiltration of China. ”

Lian Ziwen nodded, "That's right, but failure is the mother of success, and our country's industrial foundation is weaker." ”

"Well, that's exactly what I said." Zhou Weiguo nodded helplessly, and continued to groan and speak, "It's really not in a hurry." ”

……

Qingdao, a wharf, independent division shipyard.

"Captain Zhang, this is our newly built battleship." A lean middle-aged man pointed to the battleship on the sea, "It's a test of the waters, but in terms of performance, it should be no less than other warships in our navy." ”

Zhang Qian looked at the pitch-black battleship and narrowed his eyes, "I'll let people go into the water for a sea trial in a while?" ”

"Of course!" The middle-aged man nodded, "Otherwise, I won't call you, this battleship, comparable in size to the Japanese Yamato, is even surpassed, with a standard displacement of 70,000 tons!" You know, the Yamato is only 65,000 tons! ”

Zhang Qian touched his chin, "How's the aircraft carrier plan?" ”

"Two-thirds of the way through!" There was a gleam in the middle-aged man's eyes, "In a few months, I should be able to launch a sea trial!" ”

"Yes, Yan Gong! So you've already started construction here, right? Before my Navy decides to retire? Zhang Qian smiled, "Isn't it?" ”

"Of course! Otherwise, do you think that our independent teachers all eat rice? Yan Gong smiled, "Okay, although there is occasional light snow and rain in the weather these days, it should not affect the sea trial." ”

"Okay, I'll arrange it!" Zhang Qian nodded, looked at the black gun muzzle above the battleship, smiled with satisfaction, and took people back.

The independent division is now sharpening its troops.

Preparations began in all directions, hoping to cooperate with Zhou Weiguo and hit the Japanese army with one blow.
