Chapter 269 Experience Supersonic Speed
Chapter 269 Experience Supersonic Speed
After two days of wild play at the Aoying Flight Test Base, Kang Chi successfully obtained a fixed-wing and helicopter flight license. With this license, he can legally and legally drive the Silver Crane out for a ride.
The test of the WS-30 is still ongoing, but because this engine performed so well in all aspects after passing the first round of tests, its level was directly raised to the highest level and it was directly sent to Mianyang to start the third round of high-altitude platform tests.
After all, the second round of tests was actually a bit rough.
For example, the bird impact test, which is the same as the car collision test, will definitely damage the engine. The only difference is how big the bird can be.
If it can’t even withstand the smallest bird, it means that the engine is not qualified, and the reason must be found out and redesigned and improved.
Such a test means that many prototypes are needed. If it is not urgent, it can be built and tested at the same time, and improved at the same time.
But after the level is improved, this kind of test that will definitely damage the engine can be left to the later stage, which can also give Datang Heavy Industry more time to build a test machine.
Six people from 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 loaded into the transport plane, Kang Chi suddenly became playful again, turned his head and asked Chen Hai: “I want to experience supersonic flight, can you help me apply for it?”
Chen Hai was stunned.
”I can’t fly a jet plane…”
”I didn’t say I wanted to take yours, you can just let Li Xiangnan take me back to Dongyang, don’t worry, all expenses will be paid by Datang Heavy Industry!”
”…”
Is this a problem of who pays for the expenses? !
Seeing Chen Hai’s speechless expression, Kang Chi added confidently: “Our company is going to develop a small bypass ratio engine next. I want to experience the aircraft with this engine first. Is this a sufficient reason?”
“…”
Chen Hai had to sigh helplessly.
”Wait for me here for a while.”
After Chen Hai finished speaking, he went directly to the general manager of the base and made an application.
Although they all knew that Kang Chi was definitely satisfying his curiosity and had nothing to do with making engines.
But as long as Mr. Kang’s needs were not too excessive, would he be disappointed? So the application was quickly approved.
When Kang Chi followed Li Xiangnan and Shen Ye to the hangar and saw the two-seater J20 inside, his eyes lit up immediately.
So cool! This visual shock is much stronger than the photo!
“This is the ultimate toy for men!”
“…”
Looking at Kang Chi who was as excited as a child, the two of them laughed immediately.
Li Xiangnan has become somewhat immune to Kang Chi’s state these two days.
Although it is a bit exaggerated, this kind of Kang Chi makes them feel more real. Otherwise, they always have the illusion and sense of distance that this guy is not a human…
The ground staff helped Kang Chi put on his flight suit and helmet, helped him sit in the back seat, and closed the cabin door after confirming that the seat belt and mask were worn.
When starting the plane, Li Xiangnan couldn’t help but remind him again: “Remember, don’t touch any buttons by mistake.”
”Well, I promise to sit and enjoy the scenery!”
Li Xiangnan nodded. In fact, the weapons of this plane were all unloaded. Even if Kang Chi pressed the missile launch button, it would be useless. The main thing was to worry that he pressed the parachute button…
Under the guidance of the ground crew, the plane quickly slid onto the runway. The transport plane carrying the silver crane in front had just taken off, and it was their turn next.
”Mr. Kang, sit tight!”
After getting permission from the tower to take off, Li Xiangnan greeted him and began to gradually increase the throttle.
However, considering that it was Kang Chi’s first time to ride a fighter, he flew very carefully and did not dare to do too much acceleration. The minimum take-off distance was more than 200 meters, but he slid more than 600 meters before flying. Even so, the strong push on the back still made Kang Chi feel very excited.
Malaysia is pushing small aircraft, it’s awesome! The low bypass ratio engine of the fighter jet, especially the WS-15 with afterburner, has basically reached its thrust limit. The new technology that can be added to it is mainlyIt is a variable duct, which can make the fighter more fuel-efficient when cruising, increase the combat radius and ammunition load.
In order to pursue stealth performance, the fighter’s engine is built into the fuselage, so this variable duct technology cannot be an external duct, but an internal duct.
Because the external duct changes, the fuselage may have to be redesigned, and the precious space of the fuselage is wasted.
But the design difficulty of changing the internal duct is obviously more difficult than changing the external duct. If the afterburner still adopts the traditional rear design, it may be simpler.
But if you want to have a front afterburner like the WS-30 to shorten the length and weight of the engine, it means putting a variable internal duct on the fire, and it is roasted inside and outside…
The design difficulty and material requirements are suddenly higher.
Kang Chi didn’t know whether PG01 could bear it, so he could only let Yan Hui and others try to build it first.
“Mr. Kang, do you feel okay?”
”Yeah, I’m fine. What was the maximum acceleration just now?”
”2G.”
”How about letting me feel 4 or 5G?”
”No, the superiors require that it can only be controlled at 2G.”
”It’s okay, my body can bear it.”
”Sorry, this is the superior’s request. I can’t violate the regulations. You just need to experience it appropriately. There’s no need to joke with your body… We are about to enter the supersonic state.”
As soon as Li Xiangnan finished speaking, Kang Chi felt that the roar of the air around the plane began to increase significantly, pressure waves began to form, and the fuselage of the plane began to tremble slightly. When the plane finally broke through Mach 1, the wind noise disappeared immediately, and only the noise of the engine through the fuselage could be heard.
However, at this time, the noise-isolating headphones cannot be taken off, after all, the noise of the aircraft engine is not vegetarian…
Looking at the clouds outside the window passing quickly, it seems that time has become blurred because of the speed increase. This dazzling experience makes Kang Chi sigh.
Only technology can bring this unprecedented experience to humans…—— 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 meditating with his eyes closed, immediately opened his eyes and looked at Ren Zhou.
“Did I disturb your work?”
“It’s okay. Today we are mainly testing the elevator. It’s not a big problem. I don’t need to watch it on site.”
“That’s good. Is everything going well in the sea trial?”
“It’s going well.” After taking off his coat, Ren Zhou replaced Chief Shen’s cup with a pot of hot tea, and then drank a sip of tea himself and continued, “Currently, everything is going according to the schedule. Maybe this one is faster and that one is slower, but the overall situation is still relatively ideal… You came here specially, you won’t come to urge the progress again, right?”
“Did I push you so hard?”
“No way, you just didn’t feel it.”
Shen smiled immediately: “No wonder you all acted like mice seeing a cat when you saw me… Well, no joke, I came here this time mainly because of something Dr. Kang mentioned to me the day before yesterday.”
“Dr. Kang? Kang Chi?”
“Yes.”
Ren Zhou immediately came to life.
“What did he say?”
“He wants you to help him design a drone carrier.”
Drone carrier! ? ? Ren Zhou was stunned.
