"Is this your improved aircraft?"
One day in late April, a group of people from the institute came to the tarmac in front of the institute.
The institute has a runway, but it is not as good as the one at Fenghuangshan Airport. It is just a paved earth runway and then it was compacted, so it is no problem for one or two planes to take off.
If the institute expands, the runway can also be widened and it is not impossible to become a formal airport.
The reason why everyone gathered here today is because the people in the equipment team solved the problem of the laminate based on the ideas provided by Li Hang.
Laminates are meant to be cut into thin wood slices of appropriate thickness, and the thin wood slices are pressed together in three, five or more layers through appropriate pressure and glue. The wood grain direction of each layer of thin sheets must be at a 90-degree angle to the wood grain direction of the adjacent layer, so that the strength and shrinkage rate in the longitudinal and transverse directions are close to each other.
Because the damage to the Yi-15 and Yi-16 also requires laminate repair, Central University is studying the matter of laminates.
So Wang Zhu went to Central University to recruit Professor Yu Zhongkui, who was responsible for researching laminates.
The wood is still made of birch, which is the most trouble-free because there are a lot of birch in places such as Sichuan and Xikang.
It works fine for the time being. As for how to transport the birch wood down from the mountain if it is needed on a large scale, that is a matter later.
Li Hang owned the wood planer. He had bought it specially before, but now he gave it to the research institute.
There is also glue, which Li Hang also bought.
That leaves just the question of the press.
Who told Nanchang Aircraft Manufacturing Factory to have a 100-ton press bought from Italy?
There were people, technology, and raw materials, so in less than twenty days, the equipment team solved the problem of birch and paulownia wood laminates.
Then after overtime modifications, the wooden plane Li Hang drove had a completely different look.
The shape and structure have not changed, but the material has changed significantly.
So a real trainer aircraft just appeared.
Of course, with the foundation laid by Li Hang and the efforts of everyone at the Aviation Research Institute, it was very fast.
"This plane is so ugly!" Someone looked at the unpainted plane in front of them and complained in a low voice.
"There is no baking or painting. Once it is done, it will be the same as the I-15 and I-16 used by the Air Force."
"Team Leader Zhu, are you sure there is no problem with the structure of this aircraft? How is the quality of the laminates?" Wang Zhu came to the aircraft, knocked on the wooden shell, and then climbed onto the aircraft to check, and then came down to ask the equipment team leader Zhu Lin's opinion.
"No problem. The laminates are pressed with a press. We have tried it and the effect is very good. However, deeper tests have not been carried out, but it is just a test flight. There is no problem.
It makes no sense that Deputy Team Leader Li could fly to Chengdu before, but after we modified it by hand, it couldn't fly. " Zhu Lin assured, patting his chest.
"Li Hang, do you dare to fly?" Wang Zhu turned around and looked at Li Hang after hearing this.
"Of course it's no problem." Li Hang immediately assured him.
Mainly because he is the only one in the group who can fly a plane, and only he can complete the test flight tasks.
Soon, Li Hang boarded the plane and started to take off.
As the plane took off again, everyone couldn't help but applaud. Li Hang even tried climbing and diving at a faster speed.
It's just that you don't want to dive too fast to avoid losing control of the aircraft.
The flight lasted only a few minutes, but the significance was extraordinary.
And because Paulownia wood is used in many places, the weight of the aircraft is reduced a lot, which also improves the flexibility of the aircraft.
Li Hang has flown the previous airplane, and now that he is flying it again, he can clearly feel the changes.
"It seems that we need to set up two groups."
When Li Hang came down, Wang Zhu's eyes flashed as he looked at the improved aircraft.
"Director, we don't have that many people now." Someone raised a question.
The entire research institute is also a start-up, and there are only a few people on the flight crew.
During this period of time, I have been busy designing new fighter aircraft. How can I find time to dedicate some people to take care of this training aircraft?
"Go to Central University and Southwest Associated University to recruit people. I believe many people will be willing to come. Workers can go to several other aircraft factories to recruit workers. I remember that the aircraft manufacturing factory in Shaoguan is currently copying the I-15.
Tell them to stop copying.
The Yi-15 is a biplane, what’s the point of imitating it? I went to Deputy Director Huang and asked him to go to Shaoguan Aircraft Factory to ask for people. "Wang Zhu naturally has a way.
Lao Huang came from the Guangdong Air Force, represented the Guangdong Gang in the Aviation Committee, and had a relatively close relationship with the Shaoguan Aircraft Factory.
It may not be possible for others to ask for help, but he will definitely be fine.
As for the Yi-15 copied by Shaoguan Aircraft Factory, it is also a mixed race, a mixture of China, the United States and the Soviet Union.
The Soviet Union was unwilling to provide production drawings of the I-15, so the Shaoguan Aircraft Factory copied it itself.
But there were no important parts such as the engine, so we made a replica of the outer casing. The core parts inside were made from Hawker II and Hawker III components.
Even if it is a shell, the copying speed is not fast, but the advantage is experience, so Wang Zhucai thought of poaching people from there.
"Director, this is just a training aircraft." Someone reminded.
Is it inappropriate for a training aircraft to make such a big fuss?
"We built this ourselves." Wang Zhu emphasized, "We need to accumulate experience on this trainer aircraft. As long as we overcome those problems, it will be of great help to us in creating new expulsion opportunities.
During this time, we need to determine the size of the entire aircraft, especially the specifications of each component, so that we can facilitate mass production later. "
"What's the name of this plane?"
"This is the first trainer aircraft developed by our research institute. Let's call it the Yanjiao Type 1 trainer aircraft. As for the specific models later, we will wait for the Aeronautical Commission to decide."
. . . . . .
"Beautiful lady, how much do you plan to sell this lighter for?"
In a factory in the suburbs of New York, John, who is over middle-aged, looked at Chen Lu in front of him with very eager eyes.
It wasn't the lustful eyes, but the look on his face when he saw his savior.
Quite simply, his factory is a foundry, and it was previously responsible for assembling lighters for other companies.
It’s just that the impact of the Great Depression was too great. Even now, the economy has not returned to the prosperity it enjoyed before the Great Depression.
In addition, the demand for lighters is still there and is on a downward trend, and John's factory is not having a good time.
To put it bluntly, the United States at this time has a problem of overcapacity.
After the Great Depression, all countries implemented trade protection policies, which greatly affected the United States, which pursues a free economy. Therefore, they maintained their cooperation with the Soviet Union and Germany, and at the same time exported various military supplies to Japan in large quantities during Japan's invasion of China.
This is actually a way to expand exports.
Of course, Lao America is also exporting to China.
Make money from both sides at the same time.
But this has nothing to do with John, his factory needs to survive.
