Rebirth 1975: Tore up the call-back order at the beginning

Liaoshen Aircraft Factory. Internal guest house!

Zhou Yang was about to take a shower and rest, but he heard a rapid knock on the door.

When he came to the door, he looked out through the cat's eyes, and found that Gu Zhenhua and Huang Zheng were standing outside.

Afterwards, Zhou Yang opened the door.

Seeing Zhou Yang's disheveled appearance, Gu Zhenhua immediately asked with a smile, "Why are you getting ready to rest?"

"After tossing for a long time, I'm sweating a lot, and I'm going to take a bath!"

Then Zhou Yang asked again: "You two didn't accompany the leader, why did you come to my place?"

Gu Zhenhua said with a smile: "The leader is accompanied by Director Zou and Deputy Director Lang, so the two of us will not join in the fun!"

And Huang Zheng, who has a straightforward personality, said bluntly: "We are all engaged in technology, what are we doing to join in the fun? How awkward, and besides, we are not qualified!"

Zhou Yang smiled and didn't speak, but staggered his body and motioned for the two to enter the room!

Gu Zhenhua immediately said: "We won't go in, call your guards and take you to a place!"

"Where do we need to call the guards?" Zhou Yang asked curiously.

"Hehe, just tell me, where do you go without a guard?" Gu Zhenhua said with a smile.

Zhou Yang: @#￥%

Just as he was talking, Chen Beixuan also came out of the room when he heard the commotion.

Seeing this, Zhou Yang immediately asked him to lock the door, then buttoned it, and followed Gu Zhenhua and others downstairs.

Downstairs, two jeeps were already waiting for them.

Under Gu Zhenhua's instructions, several people got into the car and drove towards a tall building in the distance.

Soon, the car arrived at an assembly workshop of the Liaoshen Aircraft Manufacturing Plant.

When Zhou Yang and others came over, there were two military green helicopters parked in the workshop, and many people were busy surrounding the two planes.

With just a glance, Zhou Yang saw several familiar figures in the crowd: Gao Tingye, Qi Tongguang, Zeng Anning, Li Weidong, Li Aiping...

Before arriving at the plane, Gu Zhenhua clapped his hands, and then said loudly: "Comrades, put aside your work and come over to assemble!"

Soon, the staff next to the two helicopters surrounded them and lined up neatly under Gu Zhenhua's order.

After everyone lined up, Gu Zhenhua pointed to Zhou Yang and said to everyone: "Let me introduce to you, this is Zhou Yang, the chief designer of our "Shanying" helicopter..."

"Clap clap clap!!!"

Before the words were finished, there was warm applause in the entire assembly workshop.

Seeing this, Zhou Yang immediately stepped forward and bowed to everyone, which was regarded as a response to everyone's applause.

And his actions made the applause even more intense!

After the applause fell, Gu Zhenhua said again: "Due to work reasons, Comrade Zhou Yang did not participate in the later development of the "Shanying", but the early design and technical demonstrations were basically completed by him alone. It can be said that without him There would be no "Mountain Eagle"!"

"Tomorrow the "Shan Ying" will officially make its first flight. Before that, I invited Comrade Zhou Yang over. First, let him see our achievements. "What room for improvement!"

Zhou Yang smiled and said, "I don't dare to take it as a guide, everyone should take it as a joint exchange and discussion. After all, researching helicopters is not my specialty!"

Gu Zhenhua: @#￥%

Huang Zheng: @#￥%...

Gao Tingye: @#￥%

........

After the simple greetings, under the instruction of Gu Zhenhua, these staff members introduced the situation of the two helicopters in front of Zhou Yang:

"Shanying is a general-purpose helicopter with two engines and one blade. The main onboard equipment includes high-frequency/radiation modulation radio, Doppler radar, code selection and identification devices, etc.!"

"The fuselage is 15.26 meters long, 2.4 meters wide, and 5.2 meters high. The weight data empty weight is 5801 kg, the mission take-off weight is 7508 kg, and the maximum take-off weight is 9279 kg!"

"According to our test data, Shanying has a maximum level flight speed of 286 km/h, a maximum cruising speed of 258 km/h, a vertical climb rate > 2.28 m/s, a practical ceiling of 5790 meters, a hovering altitude of 2895 meters, and a maximum takeoff altitude of 30 meters. Weight, maximum internal fuel and 600 minutes of remaining fuel, the range is 2.3 kilometers, and the battery life is [-] hours..."

After listening to the staff's report, Zhou Yang was quite excited.

The name "Mountain Eagle" was invented by Zhou Yang, not only because he prefers birds of prey like the Mountain Eagle, but also because this helicopter is a copy of the "Black Hawk" of the Bandit Hawk.

Although the Black Hawk is slightly different from the "Black Hawk" helicopter in terms of fuselage size, especially in terms of weight, it is similar to the Black Hawk in terms of test data.

Coupled with the extremely similar appearance, this is exactly the twin brother of the Black Hawk helicopter, a copycat version of the Black Hawk, referred to as "Mountain Eagle".

Originally, Zhou Yang’s expectations for this helicopter were not too high. After all, this is not an area he is particularly good at. When he decided to start this project, Zhou Yang felt that as long as it can achieve 60% of the performance of the Black Hawk helicopter, it will be considered a success. .

But what I didn't expect was that the final product would be so amazing that it reached more than 90% of the performance of the Black Hawk.

Although this is just a general-purpose helicopter and does not carry any weapon systems, for the military that is seriously short of helicopters, the advent of the Shanying Helicopter is of great significance.

Just as Zhou Yang was meditating, Gu Zhenhua's voice suddenly sounded next to his ear: "Comrade Zhou Yang, you heard what happened just now. Do you think our "Mountain Eagle" has achieved your design goal?"

Zhou Yang did not hesitate, and said in a deep voice: "Strictly speaking, it has not yet been achieved. For example, in terms of weight, it is at least 500 kg heavier than I designed, and for example, the speed and range are also worse than I expected!"

Just when everyone was disappointed, Zhou Yang changed his voice and said again: "However, considering our current conditions and industrial level, it is already very good to be able to achieve this level. At least I am very satisfied!"

"Then is there any improvement for "Mountain Eagle"?" Huang Zheng asked in a deep voice.

"There must be, but I have to analyze the specifics after watching the flight of the "Shanying" myself!"

Then Zhou Yang said again: "However, at present, the workmanship of these two fighters is relatively rough in many places, and many parts are handcrafted, which are inferior in accuracy and other aspects!"

"If this fighter can pass the inspection of the Aviation Commission and be mass-produced smoothly, through industrialized production, the accuracy of parts and components will be greatly improved, thereby improving the performance of the aircraft, so the potential of this fighter is still very large!"

"Clap clap clap..."

As soon as Zhou Yang finished speaking, there was a burst of applause in the assembly workshop.

After the applause fell, Gu Zhenhua said loudly: "Comrades, if you have any questions, you can ask Comrade Zhou Yang for advice now!"

As soon as the voice fell, a middle-aged technician asked: "Comrade designer, I have read your design draft, and I saw that the maximum speed designed on it is 300 kilometers per hour. Can the helicopter really fly so fast?"

"Yes, it's just that with our current technological level, it is still difficult to reach this speed!" Zhou Yang said.

Whether the speed of the helicopter can exceed 300 kilometers per hour, the answer is obvious, it is definitely possible.

For example, the Mi-2009nm Super Night Hunter that Da Mao served in 28 has a maximum speed of 300 kilometers per hour.

There is also the Ka-52 Alligator, a multifunctional all-weather attack helicopter also manufactured by 2 Damao, with a top speed of 302 kilometers per hour.

Another example is the multi-purpose helicopter nh90 jointly produced by four European countries. This type of helicopter adopts a composite material structure and an advanced flight control system, which can perform tasks in various severe weather and complex terrain conditions, with a maximum speed of 305 kilometers per hour.

Therefore, when Zhou Yang designed the "Mountain Eagle", the maximum speed was set at 300 kilometers.

However, he also knows that it is difficult to achieve with the current domestic technological level, but he can set goals for the future improvement of "Shanying".

"Comrade Zhou Yang, I would like to ask, what is the level of our "Mountain Eagle" in the world..."

"Comrade Zhou Yang, Shanying's engine..."

"Comrade Zhou Yang..."

Soon, Zhou Yang was surrounded by the researchers in front of him...
