Su Youwei was scolded by Jiang Chen.
In addition to the attention of the two academicians.
Immediately, her face turned red. She quickly sat up straight and replied,
"Vice President Xiaojiang.
I'm ready!
You can start now!"
Jiang Chen looked at the three attentive audiences with satisfaction.
He began to explain the research and development direction of the variable cycle self-adapting engine!
"I think the three of you are clear.
The core of aircraft engine improvement was how to improve fuel efficiency!
The principle of a jet plane was to suck air into the engine and mix it with fuel to heat it up. Then, the high-temperature and high-pressure gas would be ejected backward.
According to Newton's third law, the aircraft could find a way to obtain reverse thrust during this process.
However, this high-temperature and high-pressure gas itself contained a lot of energy. In other words, this energy was wasted!
But for the sake of mobility, they had to do so.
In the past, the aircraft could only operate in the vortex jet mode if it was a vortex jet, and could only operate in the vortex fan mode if it was a vortex fan.
During the entire flight.
There were often many routes that did not require such a high fuel consumption method of work.
When approaching the battlefield, in order to engage the enemy, high-speed maneuvers were required. For aerial combat, transonic flight mode was required!
Therefore, the variable cycle self-adapting engine that I conceived is to combine these three modes and plan it reasonably to achieve the best use effect!
At this point, he should be able to understand, right?”
Jiang Chen wrote down the key points he had just explained on the blackboard.
Newton's Third Law-Reverse Thrust-Waste of Energy-Combination of Models…
Liu Runzhi and Song Guosheng nodded.
Jiang Chen's idea was very clear, which was the same as the variable cycle self-adapting engine proposed by the bald eagle and the hairy bear.
The most important question now was how to achieve this combination!
On the other hand, Su Youwei was already feeling a little dizzy…
She was not a genius who was good at scientific research.
The reason why she wanted to take the postgraduate entrance examination was to find a good job. What Jiang Chen had said just now was beyond her knowledge…
However, it was still possible to just take notes.
After giving Jiang Chen an OK sign, Jiang Chen continued,"
"The engine's structure is generally from front to back, with the air intake, the turbine, and the exhaust.
The corresponding process was air intake, air compression and supercharging, air mixing and combustion, driving the turbine to rotate, and the tail of the engine to do work.
The variable cycle engine used a turbine fan system to divide the airflow into three passages…
The three tunnels could change the size of the caliber and achieve the best working mode through combination.
When an economical cruise was required, the two adjustment plates were adjusted downward to block the airflow through the combustion chamber, allowing the engine to work in propeller mode.
When a transonic maneuver was required, the adjustment plate 1 was down and the adjustment plate 2 was up to form a fan engine.
When it is going to cruise at supersonic speed, the adjustment plates 1 and 2 are inclined upwards, turning it into a turbine jet engine…"
Jiang Chen was writing down one chalk after another. He was writing out formulas, theories, calculation equations, and structural designs on more than ten blackboards.
Liu Runzhi and Song Guosheng were dumbfounded when they saw the research and development plan for the variable cycle self-adapting engine on the blackboard.
Even though they had a lot of knowledge, they still felt a little dizzy looking at Jiang Chen's writing on the blackboard.
It wasn't until Jiang Chen requested it that the two of them suddenly realized something.
In the end, the two of them finally understood Jiang Chen's plan.
He looked back at the development plan of the variable cycle self-adapting engine.
The two of them were so shocked that they could not speak.
With the same fuel consumption, the time of flight of the fighter aircraft using the variable cycle self-adapting engine could be increased by 50%, the flight range could be increased by 33%, the fuel consumption rate could be reduced by 25%, and the fuel heat absorption rate could reach 60%...
No wonder it could meet the stringent requirements of a sixth-generation fighter jet!
The most important thing was…
The research and development direction Jiang Chen had mentioned was actually a complete research and development plan.
A technological barrier?
Within these two hours.
Jiang Chen had already conquered it…
It was a perfect solution.
The world's leading variable cycle self-adapting engine technology was written on the blackboard in this calculation room at this moment...
The only thing they needed to do was to implement the variable cycle self-adapting engine technology!
No wonder Jiang Chen had said that he would be able to produce the variable cycle self-adapting engine in 20 days. In fact, he didn't need 20 days at all...
If only the research institute and the factory worked a little harder.
Maybe it could be done in 15 days!!
In 15 days, the variable cycle self-adapting engine that the bald eagle and hairy bear had claimed would take 30 years to complete had landed on the ground…
Jiang Chen, this little bastard.
What kind of god was he?
………………
P.S. I haven't even dared to send the contract yet. I'm begging the readers to give me a ticket.
This way, I'll have the confidence to mail the contract tomorrow. Sob…
