Technology: The first development of a sixth-generation fighter

Su Youwei was said by Jiang Chenyi.

In addition, the attention of two academicians was added.

Suddenly, his face turned red, and he quickly sat down and replied:

“Vice President Xiaojiang.

I’m ready!

You can get started! ”

Jiang Chen looked at the three attentive listeners with satisfaction.

Directly began to explain the research and development direction of variable cycle adaptive engine!

“I think all three of them know that.

The core of aircraft engine improvement is how to improve fuel efficiency!

The principle of the jet aircraft is to suck air into the engine and mix the fuel for heating, and then the high temperature and high pressure gas is injected backwards.

According to Newton’s third law, airplanes can find that one in the process to get reverse thrust.

But this high temperature and high pressure gas itself has a lot of energy, that is, this energy is wasted!

But for the sake of mobility it had to be done.

In the past, the aircraft often could only work in the turbo spray mode, and the turbofan could only work in the turbofan mode.

During the entire course of the aircraft’s voyage.

There are often many distances that do not require the use of this high fuel consumption rate of operation.

When approaching the battlefield, in order to meet the enemy, high-speed maneuvering is required, and in order to maneuver air combat, transsonic flight mode is required!

So the variable cycle adaptive engine I conceived is to combine these three modes, plan reasonably, and achieve the best use effect!

At this point, you should be able to understand, right? ”

Jiang Chen wrote down several key points on the blackboard that he had just explained.

Newton’s third law – reverse thrust – energy waste – pattern combination ….

Liu Runzhi and Song Guosheng nodded one after another.

Jiang Chen’s thinking is very clear, which is consistent with the starting point of the variable-cycle adaptive engine proposed by Bald Eagle and Mao Xiong.

The next most critical question is how to achieve this pattern combination!

However, Su Youwei on the side was already a little dizzy…

She is not a genius who is good at scientific research herself.

The reason why the graduate school is to find a good job, just now Jiang Chen said that it is already a little beyond the scope of her knowledge…

But just keeping a record can be done.

After making an OK gesture to Jiang Chen, Jiang Chen continued:

“The engine is generally constructed from front to back as an intake – compressor – combustion chamber – turbine – nozzle.

The corresponding process is air inhalation – air compression and supercharging – air mixing combustion – driving the turbine rotation – tail jet to do work.

The variable-cycle engine uses a turbofan system that divides the airflow into three bypasses….

The three bypasses can be changed in size and caliber, and the best working mode can be achieved by combining and collocation.

When economic cruising is required, the 2 adjustment plates are adjusted downwards, blocking the airflow through the combustion chamber and allowing the engine to work in propeller mode.

When transsonic maneuvers are required, the adjustment plates 1 down and 2 upwards form a turbofan engine.

When it comes to supersonic cruise, the adjustment plates 1 and 2 are deflected upwards, making it a turbojet engine…”

The chalk in Jiang Chen’s hand is one after another, formulas, theorems, calculation equations, and structural designs are frantically output on more than ten blackboards.

Liu Runzhi and Song Guosheng looked at the research and development plan of the variable cycle adaptive engine on the blackboard and was almost stupid.

Around the two people’s deep knowledge reserves looking at Jiang Chen’s board book is also a bit of a brainstorm.

It wasn’t until Jiang Chen ordered that the two had a sense of sudden enlightenment.

In the end, the two finally understood Jiang Chen’s plan.

Let’s look back at the development of the entire variable-cycle adaptive engine.

The two were speechless in shock.

In the case of the same fuel, the air lag time of a fighter with a variable-cycle adaptive engine can be increased by 50%, the range increased by 33%, the fuel consumption rate by 25% can be reduced, and the fuel heat absorption rate of 60% can be achieved….

No wonder it can meet such a demanding requirement of the sixth-generation fighter!

Most importantly.

The research and development direction in Jiang Chen’s mouth is actually a complete research and development plan.

Technical barriers???

Within two hours.

Jiang Chen has already conquered it….

Perfect couldn’t be more of a perfect solution.

World-leading variable-cycle adaptive engine technology, at this moment in this calculus chamber …

The only thing they need to do is put the variable cycle adaptive engine technology to the ground!

No wonder Jiang Chen said that 20 days can land the variable cycle adaptive engine, in fact, where it takes 20 days…

If they institutes and factories give a little extra work.

Maybe it will take 15 days!!!

In 15 days, the variable-cycle adaptive engine that Bald Eagle and Woolly Bear threatened to take 30 years to complete landed on the ground….

Jiang Chen, this little king is a bastard.

What kind of gods are they!??
