"Manager Ye, a friend just called me and said that your company No. 9 Technology is going to order a private jet?" He Feng asked with undiminished enthusiasm.

"Yes, I wonder if it would be convenient for you to introduce it to me?"

"I happen to be in Yanjing now. If it's convenient for you, I'll go there and introduce it to you in person." He Feng asked impatiently.

"Okay, then you can go directly to the new office building of No. 9 Technology. Do you know how to get there?"

"Tell me where you are and I'll be there right away."

"My WeChat number is the same as my mobile phone number. Add me and I will send you my location." Ye Yuxin said directly.

"That's fine, we'll talk later."

"OK."

"How is my sister-in-law?" Zhou Meng stretched his neck.

"Comac's chairman He Feng will be here soon, we'll ask him then." Ye Yuxin explained.

"How long will it take?" Zhou Meng was a little impatient.

"It's hard to say. It depends on where he is in Yanjing. If it's far away, it will take some time." Ye Yuxin said uncertainly.

"Then I'll go to the industrial park first."

"Okay, shall I call you over later?"

"No, do it yourself." Zhou Meng's enthusiasm only lasts for three minutes, and then it's gone.

"All right."

"......"

One hour later.

He Feng came to Ye Yuxin's office.

"Hello, Manager Ye, I'm He Feng." A big man who was about 1.8 meters tall and weighed nearly 150 kilograms appeared in front of Ye Yuxin.

"Hello, Mr. He, please take a seat." Seeing that only He Feng came, Ye Yuxin asked, "Mr. He, are you here alone?"

"Originally there was a colleague here, but he was busy with other things, so I came here alone." He Feng said with a smile.

"......" Ye Yuxin didn't care. After asking He Feng to sit down, she poured him a glass of water.

"Manager Ye, I wonder what your requirements are for the aircraft? Can I introduce it to you?"

"I want to buy two, one for Liu Chi as a private jet, and one for the company as a business jet. Anyway, everything depends on suitability. Do you have any good recommendations?" Ye Yuxin thought about it and decided to order two.

"We now have three models: C919, C929 and ARJ21."

"Would you mind introducing everything to me? I don't know much about this." Ye Yuxin didn't know much about airplanes, so she asked directly.

"OK."

He Feng said directly: "Let me introduce you to the ARJ21 first. It is a turbofan aircraft designed by us for new regional airliners. It is a 70-90-seat turbofan aircraft. It is my first turbofan regional aircraft with independent intellectual property rights."

“It is designed to meet the operational requirements of taking off and landing at high-temperature and high-altitude airports and overcoming obstacles on complex routes. The life cycle cost (LCC) is strictly controlled at the beginning of the design to minimize maintenance costs and improve the economic efficiency of the aircraft.”

"At the same time, we try to maintain commonality in the cockpit human-machine interface, maintenance human-machine interface and corresponding operating procedures, which can reduce the cost of pilot replacement training for airlines and increase the flexibility of aircraft deployment and use."

"We are now developing the ARJ21 aircraft in the direction of serialization, with four models: ARJ21 basic model, extended model, cargo aircraft and business jet."

"The ARJ21 aircraft adopts a double-circular profile fuselage with five seats per row, a lower single wing, two CF34-10A advanced turbofan engines powered by short-ducted separated flow (SDSF) power units, a high horizontal tail, and a front three-point retractable landing gear layout."

"The cockpit adopts a two-person system, the avionics system uses advanced bus technology, LCD flat panel display and integration, and the conventional mechanical system adopts internationally mature advanced technology."

"In general: the ARJ21 aircraft is adaptable, comfortable, economical and common."

"Is there a private model of this ARJ21?" Ye Yuxin asked when she saw He Feng stopped.

"Yes, there are also business jet models." He Feng nodded.

"What about other models?"

"Then let me introduce you to the C919."

"The C919 is also a medium- and short-haul trunk passenger aircraft. Its basic layout has 168 seats, a standard range of 4,075 kilometers, an increased range of 5,555 kilometers, and an economic life of 90,000 flight hours. It is in the same class as the Airbus A320 and Boeing 737."

"The C919 is designed with a number of advanced technologies, including:

"The use of advanced aerodynamic design technologies such as advanced aerodynamic layout and a new generation of supercritical wings has achieved better cruise aerodynamic efficiency than similar aircraft currently in service, and has comparable cruise aerodynamic efficiency to competing aircraft in the market ten years later!"

"We mainly have two types of aircraft, and we also have the CR929 wide-body passenger aircraft."

"......" Ye Yuxin nodded, waiting for the next words without saying anything.

"The CR929 wide-body aircraft is a major strategic cooperation project between Chinese and White Bear (Northern) companies, and the finished product has not yet been produced."

"If you place an order, I suggest you consider the route issue. If your requirements are not high, I recommend the ARJ21."
