Li Wenjun waved his hand: "It's okay, the engine is overheating."
Han Weijun sighed: "We have been working on this acceleration lag for a long time and thought of many ways, but we still can't completely solve it."
Li Wenjun: "Turbocharging requires exhaust gas to drive the turbine impeller, thereby increasing the intake air volume and pressure of the engine. When it is first started, the engine speed is low and the exhaust gas volume is small, so it cannot be supercharged, so there will be a delay, resulting in power response Affected. This is an inherent problem with turbocharging. It cannot be completely eliminated. We can only try to make up for this shortcoming by increasing the sensitivity of other components. Try to prevent the driver from feeling this lag."
Han Weijun: "Is the engine overheating? Does Director Li have any good ideas?"
Li Wenjun: "The exhaust gas at the suction outlet of the turbocharger is used to supercharge, so the temperature of the engine is higher than that of naturally aspirated air. The air flow is large, and the circulation management and thermal management are more complicated. When running at high speed, the engine is almost always It operates at high temperatures, so you can’t use the same materials as natural air intake. It’s still winter, and if you drive on the highway in summer, it won’t be long before it burns, so you have to work hard on the materials. And it’s not just the main body of the engine. Materials must be high-strength and resistant to high temperatures and wear, and various parts must also be able to withstand high temperatures. So I have always told you that even if turbocharging can be launched, the improvement of naturally aspirated engines cannot stop. Because each has its own benefits. You guys Don’t be anxious. Things should be perfected as much as possible before mass production, and don’t try to take shortcuts in the research and development process.”
Han Weijun: "I know."
Li Wenjun: "If you have any difficulties, come to me. This year, I will find ways to recruit more talents in automobile manufacturing, machinery manufacturing and material research and development to help. Go abroad more for study and inspection. I can help with German and American automobile manufacturers." Contact you."
When Li Wenjun came out of the test drive place, it was already time to eat, and a bunch of people came over to ask him to sign.
Tao Guangming asked someone to bring a meal to Li Wenjun, so that Li Wenjun could take the time to eat.
"Are you rushing to go somewhere else this afternoon?" He watched Li Wenjun finish his meal and start working again.
No matter how busy he is, he always takes time to take a lunch break.
Li Wenjun said: "Yes, I want to go to the aviation equipment place. We made an appointment at two o'clock and went to play, but the old man started to scream again."
Tao Guangming sneered: "Haha, don't you deserve this? You usually support us like this, but now you feel like being bossed around."
Li Wenjun smiled, immersed himself in handling it quickly, stood up and left.
Tao Guangming sighed: "I'll go with you. It takes half an hour to drive there. I'll drive, and you can still get some sleep."
Although Li Wenjun could definitely find a driver, he would rather drive by himself because he often has to drive into places that need to be kept secret. When finding a driver, he has to worry about the other party leaking secrets and needs to take precautions and inspections.
He always felt that Tao Ran's feelings for Li Jinyan were not that simple. If he really wanted to propose to Tao Ran in the future, wouldn't he have to build a good relationship first?
Li Wenjun raised his eyebrows: "You are suddenly so attentive and considerate, which scares me. If it's just for that bowl of noodles, there is no need. Anyway, you have come to my house so many times, not more than this time. .”
Tao Guangming's face immediately turned red: "Get out of here, I think you're pitiful, so I'm helping you. Don't forget it."
Li Wenjun: "Okay, okay. Thank you."
Li Wenjun fell asleep within thirty seconds after getting in the car.
Tao Guangming cursed in his heart: This bastard can sleep on the bed no matter how big the matter is.
But having said that, Li Jinyan has perfectly inherited the appearance advantages of Gu Zhanyan and Li Wenjun, so no wonder his daughter is confused.
Starting last year, the aviation equipment factory also introduced several Ukrainian aircraft mechanics with the help of Leto.
Therefore, the progress is much faster than before, completely relying on one's own exploration.
At this time, they made two ten-fold scaled-down models of a dual-rotor and a quad-rotor, and they were flying them in the open space outside.
It's said to be a reduced model, but it's actually an enlarged version of a drone.
It's just that drones use motors. In order to be able to carry loads and operate humans in the future, they need to use fuel engines, which are heavier. Therefore, the body balance, mechanical design, and aerodynamic performance design are much more complicated.
"Wenjun Industrial" is already terrifyingly large, but compared to aircraft research, this place is still a bit small.
For example, all aircraft, including helicopters and this tilt-rotor aircraft, can only fly in this walled area of only six square kilometers.
Further out there are tree houses and there are people coming and going, so the risk is too great.
Everyone stood in the command tower holding a telescope. Only two operators were near the model.
One is responsible for driving, and the other is responsible for controlling the rotorcraft in the car.
And the car is always on.
If anything goes wrong, drive away immediately.
Li Wenjun laughed out loud when he saw this scene with a telescope.
Tao Guangming sighed: "Tsk, tsk, tsk, are you ready to run away at any time?"
Jiang Qiangjun cursed: "Smile, laugh, laugh. You guys can relax, just take a look. Do you know how long it took us to build it so that it can fly outside? Yang Shouzhuo also knows that he can take a look when he has time. , you didn’t show up at all.”
In fact, Yang Shouzhuo didn't care about the progress, he just came to see the jokes and have fun.
Because in that simulation room, I don’t know how many units were damaged.
There are just so many situations, and they are as weird as they want to be.
Li Wenjun nodded: "I know, you have worked hard. What changes have been made since the last time I looked at it."
Jiang Qiangjun: "The battery didn't work, so in the end I made a direct fuel engine model. Other details were changed to maintain the stability of the fuselage in various shapes."
A voice suddenly came from the intercom: "Requesting instructions whether to start a test flight."
Manager of the aviation equipment company: "Let's start. Start with the twin rotors."
Then the rotor of the model over there started to spin "boom boom" and rose steadily.
The take-off and landing state is the most unsafe and difficult to operate. It is normal to be nervous.
After all, even the model cost nearly a million.
A nervous voice came from the intercom: "I, I, I'm going to start to transform."
Li Wenjun almost laughed out loud.
The manager replied with a serious face: "Well, you can change. Pay attention to safety when transforming."
The rotor of the gyroplane slowly turned horizontal.
After flying around the airport, everyone cheered and high-fived.
The manager held back his excitement and joy and said: "Let's land."
The intercom said: "Okay."
Then the gyrocopter began to slow down, intending to hover in mid-air and land slowly.
There was a sudden strong gust of wind, and the entire gyrocopter began to tilt.
