After two days of playing wild at the Eagle Test Flight Base, Kangchi successfully obtained a fixed-wing and helicopter flight license, with which he will be able to drive the Silver Crane around legally and compliantly in the future.

The test of the turbofan 30 continued, but because the engine performed too well in all aspects after passing the first round of tests, the grade was directly raised to the highest, and it was directly sent to Mianyang to start the third round of high-altitude testing.

After all, the second round of testing was actually a bit rough.

For example, the bird impact test, which is the same as the car crash test, will definitely damage the engine, and the difference can only be how large the bird can resist.

If even the smallest bird can't resist it, then the engine is not up to standard, and the reason must be found out and redesigned and improved.

And this kind of testing means that many prototypes are needed, and if they are not particularly urgent, they can be built and tested at the same time, and improved while testing.

But after the grade is raised, this kind of test, which will definitely damage the engine, can be left for later, which can also give Datang Heavy Industries more time to build the testing machine.

Six members of Datang Heavy Industry's technical team followed the engine to Mianyang, and the rest returned to Dongyang by transport plane yesterday afternoon.

When looking at the silver crane that was loaded into the transport plane, Kang Chi suddenly got up again, turned his head to Chen Hai and asked, "I want to experience supersonic flight, can you help me apply?" ”

Chen Hai was immediately stunned.

"I can't fly a jet again......"

"I didn't say I wanted to sit on you, I can directly ask Li Xiangnan to send me back to Dongyang, don't worry, we Datang Heavy Industries will pay for all expenses!"

“……”

Is this the problem of the expense?!

Seeing Chen Hai's somewhat speechless expression, Kang Chi added confidently: "Our company is going to engage in a small bypass ratio engine next, and I want to experience this kind of engine aircraft first, this is a good reason, right?" ”

“……”

Chen Hai had no choice but to sigh helplessly.

"You wait here for me for a moment."

After Chen Hai finished speaking, he directly found the general person in charge of the base and made an application.

Although they all know very well that Kangchi is definitely to satisfy their curiosity, and it has nothing to do with building engines.

But Mr. Kang's needs, as long as they are not too excessive, can they still disappoint him?

As a result, the application was quickly approved.

When Kang Chi followed Li Xiangnan and Shen Ye to the garage and saw the two-seater version of the J20 inside, his eyes suddenly lit up.

It's so handsome!

This visual shock is much stronger than in the photo!

"This is the ultimate toy for men!"

“……”

Looking at Kang Chi, who was excited like a child, the two immediately laughed.

In the past two days, Li Xiangnan has been somewhat immune to this state of Kangchi.

Although it is a bit exaggerated, such a Kangchi makes them feel more real.

Otherwise, they will always be given a sense of illusion and distance that this thing is not human......

The ground crew helped Kangchi put on his flight suit and helmet, helped him to sit in the back seat, and closed the cabin door after confirming that the seat belt and mask were put on.

When starting the plane, Li Xiangnan couldn't help but tell again: "Remember, don't touch any button by mistake." ”

"Well, I promise to just sit and enjoy the view!"

Li Xiangnan nodded, in fact, the weapons of this plane were all unloaded, even if Kangchi pressed the missile launch button, it was useless, mainly because he was afraid that he would press the button such as parachuting......

Under the guidance of the ground crew, the plane quickly taxied onto the runway, and the transport plane with the silver crane in front had just taken off, and it was their turn to be next.

"Mr. Kang, sit down!"

After getting permission from the tower to take off, Li Xiangnan said hello and began to gradually increase the throttle.

However, considering that Kangchi was the first time to take a fighter jet, he flew extra carefully, and did not dare to do too violent acceleration at all, and the minimum take-off distance of more than 200 meters, he had to slide more than 600 meters before flying.

Rao is like this, and the strong feeling of pushing his back still makes Kangchi feel very excited.

Malaysia pushes the small machine, it is cool!

The small bypass ratio engine of the fighter, especially the turbofan 15 with afterburner, in fact, the thrust has basically reached the limit, and the new technology that can be added to it is mainly a variable duct, which can make the fighter more fuel-efficient when cruising, and increase the combat radius and bomb load.

Moreover, in order to pursue stealth performance, the engines of fighter jets are built into the fuselage, so this variable duct technology cannot be changed to external ducts, but to change internal channels.

Due to the change of the outer duct, the fuselage may have to be redesigned, and the valuable space of the fuselage is wasted.

However, the design difficulty of changing the internal channel is obviously more difficult than changing the outer duct, and if the afterburner still adopts the traditional rear design, it may be simpler.

However, if you want to do the turbofan 30, the front afterburner and shorten the length and weight of the engine means that a variable connotation frame must be roasted on the fire, and it is roasted both inside and out......

The design difficulty and material requirements are suddenly higher.

Kangchi didn't know if PG01 could stand it or not, so he could only let Yan Hui and them try to build it first.

"Mr. Kang, the body feels okay, right?"

"Well, it's okay, what is the maximum acceleration just now?"

“2G。”

"Do you want me to feel 4 or 5G?"

"No, the superiors can only control it at 2G."

"It's okay, my body can stand it."

"I'm sorry, this is a request from my superiors, I can't break the rules, it's good for you to experience it properly, there's no need to joke with your body...... We're about to go into hypersound. ”

As soon as Li Xiangnan's voice fell, Kang Chi felt that the air around the plane began to roar significantly, pressure waves began to form, and the fuselage of the plane began to tremble slightly.

However, at this time, you still can't take off the sound-isolating headphones, after all, the noise of aircraft engines is not vegetarian......

Looking at the clouds outside the window passing quickly, it seems that time has become blurred because of the acceleration of speed, this dazzling and magical experience makes Kangchi a little embarrassed.

Only technology can bring this unprecedented sense of experience to human beings......

Liaodong Province, Sanshan Shipyard.

004 Project Department, after Ren Zhou received the news that Chief Shen came to find him, he immediately put down the work at hand and returned to the office from the aircraft carrier.

After hearing the footsteps, Chief Shen, who was closing his eyes and meditating, immediately opened his eyes and looked at Ren Zhou.

"Didn't disturb your work, did you?"

"It's okay, today is mainly for the test of the lift, it's not a big problem, I don't have to stare at the scene."

"That's good, everything is going well in the sea trials, right?"

"It went well." After Ren Zhou took off his coat, he changed the pot of hot tea for Chief Shen's teacup, and then took a sip of tea himself and continued, "At present, we are all walking according to the time plan, maybe this one is faster, that one is slower, but the overall situation is still ideal...... You made a special trip, you won't rush the progress again, right? ”

"Did I push you so hard?"

"No, you don't feel it."

Chief Shen suddenly smiled: "No wonder you all see me one by one like a mouse and a cat...... Well, no kidding, I'm here this time mainly for something that Dr. Kang mentioned to me the day before yesterday. ”

"Dr. Kang? Kangchi? ”

"Yes."

Ren Zhou suddenly came to the spirit.

"What did he say?"

"He wants you to help him design a drone carrier."

Drone Carrier??

Ren Zhou was stunned for a moment.
