Back in 1978, I was admitted to Northwestern Polytechnical University.

Chapter 449 C919 and C929, the passenger planes of the East have taken flight.
The capital city, a traditional courtyard house.

"Liangzi, the technology in the East is developing too fast. Many Americans can't accept it. If you're going to America this time, you have to be careful. There will definitely be people making things difficult for you."

Hearing his mother-in-law's words, Qin Liang smiled and said, "Mom, it's alright. If they dare to make things difficult for us, we'll stop cooperating. In that case, they'll be the ones who suffer. The key is Dad. As long as Dad is happy over there, that's all that matters. If he's not feeling well, he can come back anytime."

Anne nodded: "When I came back from the Spring Festival, I talked to him about it, and he did seem to be interested, but he has a lot of research projects at MIT right now, and he can't leave."

"it is good."

Yang Duo'er came out of the kitchen.

"Brother Liangzi, please wait a moment, the food will be ready soon."

"Hmm, no rush, I'll help you."

In the kitchen, a group of people were chatting and laughing when Annie suddenly spoke up.

"Liangzi, when are you two going to have a baby? You're both getting on in years, it's time to have the next generation. Just go ahead and have the baby, and I'll help take care of it! Anyway, the TOEFL exam in the East is all standardized now, it's only busy for a few days each year..."

Yang Duoer also looked up: "Yes, Brother Liangzi, a lot of people have been asking about it when we went back to our hometown for the Spring Festival."

"Okay, then we'll wait until we get back from the US this time."

"What are you waiting for!"

"Okay, let's not wait any longer. Let's make it work tonight..."

People who have received a Western education are indeed bold! They talk about these topics without any hesitation, and they're not afraid even with their mother-in-law around.

"Ah."

As Yang Duo'er spoke, she picked up a bunch of chives and continued picking them.

Annie took a piece of lamb out of the refrigerator...

Cough cough, it looks like tonight...

The next day, Qin Liang got out of bed full of energy. Sure enough, it's good to be young, especially your back... If you were over thirty, you would definitely be clutching your back and unable to get out of bed.

"Comrade Qin Liang, Elder Lin invites you."

"Didn't we talk enough yesterday? What's up? Why are we going to the airport terminal again!"

"No, this time I'm going to the Capital Airport."

"Beijing Capital Airport? Who are you picking up?"

"Picking up passengers from the airport."

Teng!
Qin Liang stood up.

Currently, the main passenger aircraft produced domestically is the Y-10. Although it has been sold to many countries, it is, after all, a modified version of an old platform and still has many problems.

The supersonic cruiser, jointly developed with Boeing, is a truly advanced passenger aircraft that is in sync with the world, and it will also set a trend!
Since it was manufactured in Shanghai, Qin Liang hadn't paid much attention to it. Now it seems that they've already started producing prototypes!

"Let's go and take a look!"

Beijing Capital International Airport.

Amidst the roar of engines, an unusually designed passenger plane slowly descended.

"Wow, Peking Union Medical College Hospital!" someone exclaimed.

"How does this become a collaboration?"

"Canard configuration, with canards in front and main wings behind, isn't that just the Concorde?"

"Does the Concorde have twin tails? Doesn't the nose of the Concorde droop when it lands?"

"Hmm, if that's the case... then it really is. But... if it's not Peking Union Medical College Hospital, then what is it?"

"I don't know, it must be a newly developed passenger plane."

Amid the watchful eyes of countless passengers, the plane slowly descended and taxied to an empty parking spot, where a group of people were already waiting.

"Seriously, this plane is really impressive!" Old Lin exclaimed. "Designed according to Western standards, it's lightweight and has a high flight speed. Liangzi, do you think we could install a radar antenna on its back and convert it into an airborne early warning aircraft?"

"No."

Qin Liang's ruthless rejection of Elder Lin's suggestion surprised everyone else present: "Why?"

"This aircraft is called the Sonic Cruiser. As the name suggests, it is designed to fly at near-sonic speeds. Although it has been modified to be transonic, the drag is still very high and the fuel consumption is higher than that of a normal aircraft. If a radar dome is installed, the speed will definitely decrease, and the transonic design of the entire aircraft will lose its meaning."

"Yes, this plane isn't suitable for us. Let's stick with the Y-10; it's a really good plane... By the way, what's its name?"

"Sonic Cruiser."

"No, I meant domestically. Should we call it Y-11?"

Qin Liang shook his head: "Of course it's not good. In fact, the name Yun-10 isn't good either... Shouldn't we come up with a completely new series of names?"

Standing to the side, Old Cheng spoke up: "That's right, it's time to come up with a new name. Liangzi, what do you think is a good one? Our Civil Aviation Administration will adopt whatever it is!"

Mr. Cheng was originally the deputy chief designer of the Y-10, and later he participated in the development of the new passenger aircraft. However, at the end of last year, he was "forced" to be transferred to the capital and became the new head of the Civil Aviation Administration of China.

With the departure of Lao Shen and his men, and the rise of Lao Cheng, the Civil Aviation Administration of China will undergo new changes, better supporting the research and development of domestically produced passenger aircraft!
It's time to change the name!

"Airbus uses the letter A, Boeing uses the letter B, and our Dongfang uses the letter C!"

“Great, that’s also the first letter of our country’s name!” Old Cheng nodded.

"Like the West, we'll use three-digit numbers. Airbus uses 3, Boeing uses 7, and we'll use 9!"

"Okay, let's use 9 then, for 'forever and ever,' that's it. What about the last two digits?"

"Our Y-10 passenger plane can seat 189 people when traveling in high-density conditions, which is 190 seats. We call it the C919 passenger plane. The current supersonic cruiser has a large fuselage and a high-density layout, which can seat more than 300 people. To make it more convincing, we calculate it as a two-class layout with 290 seats, so we call it the C929 passenger plane!"

"Okay, whatever you say! Our own passenger planes produced in Dongfang can't be named after Boeing. From now on, they'll all use our own names!" Old Cheng was very excited.

What happens next is a matter for later; for now, both of these passenger planes are doing well.

At this moment, the cabin door had already opened, the gangway was connected, and Old Ma stepped down in a few quick steps.

"Distinguished leaders, we've heard we're heading to the United States. We guarantee the Hypersonic Cruiser will successfully complete its mission!"

"Old Ma, it's been renamed. From now on, it'll be called the C929 passenger plane!"

"What?"

"Liangzi just gave it that name, it means..."

"Hmm, not bad, let's call it C929!"

"Mr. Ma, this passenger plane can already fly to the United States?" Qin Liang's eyes widened in surprise.

"Yes, the test flights have been going on for almost half a year. Boeing and we have been conducting joint test flights and have completed all the test flight subjects for the type certification. This time, we'll take our supersonic... cough cough, C929 passenger plane over to showcase the strength of the East!"

That's right, just fly over there and show off!
Boeing also has this aircraft, but it's still in test flights and hasn't been seen much in the media. There will definitely be a lot of reporters and media waiting there this time, so…

C929 makes its dazzling debut!

"Okay, as long as there are no safety issues, it's fine." Qin Liang nodded.

He himself didn't care. After all, a reborn person must have the protagonist's halo, so he would be fine. However, Zhang Lao and Qin Lao couldn't afford any accidents! Whether the passenger plane was cool or not was not important; safety was the top priority.

Now that all the test flight subjects have been completed, it is naturally safe.

Wow, that's fast! The second passenger plane is about to be released.

"Let's go up and take a look!" Old Lin took the lead.

Previously, civil aviation was also under the control of the Air Force. Now, although civil aviation has become independent, the Air Force still has a lot of say. Moreover, since Elder Cheng has become the head of civil aviation, his relationship with the Air Force is naturally very good. Therefore, Elder Lin came with the people from the aircraft terminal, and everyone rushed forward.

Although it was designed to cruise at near-sonic speeds, a dual-aisle wide-body design with high drag was used. The fuselage cross-section is 5.74 meters wide, and the internal cabin width reaches 5.49 meters, allowing for two aisles.

The business class section has six seats per row with two aisles in the middle, meaning two seats are placed side by side. The economy class section has nine seats per row with three seats placed together, which looks more impressive.

"Not bad, not bad, this space is really large. It's a pity we can't convert it into our early warning aircraft..."

"Mr. Lin, don't worry. We have another alternative project in China, with a normal aerodynamic layout. Once this aircraft is officially finalized and put into production, the normal layout project will also be developed."

In fact, by reducing the weight of the aircraft and using fuel-efficient engines, the C929 can maintain the same fuel consumption standard as existing aircraft when operating the same routes.

However, if a normal layout is used, the cruising speed will be reduced, which can save an additional 15% to 20% of fuel.

For airlines, the pursuit of fuel efficiency is endless!

Therefore, switching to the normal layout will definitely open up a larger market, and we don't plan to cooperate with Boeing on this project anymore; we'll make our own money!
Old Lin's eyes lit up: "Great!"

You little rascal, all you ever do is dig holes!

For this collaborative project, Boeing will definitely have to say good things about us, saying that our Eastern technology is just as advanced as Boeing's technology, thus establishing the reputation of Eastern technology as the world's number one, and then... ditch Boeing and do it on their own!
That was a brilliant move!
"Once we obtain the airworthiness certificate from the United States, we will begin the development of a modified version." Old Ma also spoke up: "Comrade Qin Liang, don't worry, we already have ample experience, and we can achieve our maiden flight within two years!"

"Yes, I believe you. Let's go and take a look ahead."

cockpit.

The two-person pilot system saves a flight engineer, thus saving the airline money. The cockpit is also a modern glass cockpit with five large screens, making the whole cabin feel like science fiction.

"The avionics system is mostly supplied by ourselves, with only a small portion provided by the United States. However, this is also to share some of the profits with them. In the future, we can produce our own systems at any time, as well as engines..."

When the topic of engines came up, Mr. Ma's face lit up with excitement.

Who dares to say that domestically produced large passenger aircraft are not mature? In Shanghai, we have an engine factory that collaborates with Rolls-Royce, and they still produce three-rotor engines!
"Initially, Boeing cooperated with us because they wanted to control our engine supply. Without American engines, our passenger plane could not go into production. But now... their conspiracy has been thwarted by us."

Qin Liang said with a smile, "We need to build a complete industrial chain. We're not afraid of others holding us back; in fact, we need to be able to hold others back at any time!"

"That's natural. The Americans didn't have a mature understanding of the large amount of composite materials used on this aircraft. The prototype in the Boeing factory used their own composite materials, which cracked after two months of test flights. In the end, they honestly switched to our materials."

When these things were mentioned, Mr. Ma became even more excited.

Now, our civil aviation technology has reached the forefront of the world, and in some aspects, we can even lead the world!
"Good, not bad, this is an aircraft that boosts our confidence! However, our passenger planes won't have a chance to participate in this parade..."

"How could there not be a chance?" Qin Liang retorted.

What opportunities are there?

"This passenger plane has an aerial refueling system installed at the wingtips, so it can be temporarily displayed as an aerial refueling tanker!"

Large passenger planes have a wide range of uses; they can be converted into early warning aircraft, electronic warfare aircraft, aerial refueling aircraft, and more!
Moreover, the C929, which uses a canard layout, has wide wings. The fuel stored in the wings alone is enough for the aircraft to fly tens of thousands of kilometers. If a special fuel tank is installed inside the aircraft, the entire aircraft can carry 130 to 140 tons of fuel!

That's right, this fuel capacity exceeds the maximum takeoff weight of the Y-10!

This kind of aircraft is definitely the best air nanny!

A twin-engine Q-6 fighter jet with auxiliary fuel tanks only needs about ten tons of fuel, so this aerial refueling tanker can refuel more than a dozen twin-engine Q-6 fighter jets!
This long-range attack capability will be greatly enhanced!

“That’s right, it’ll definitely be fine if we put it on the wingtip. We can start researching it soon!” Old Ma was also excited.

If it weren't for the military orders, the Y-10 passenger plane might not have survived. Now, although it mainly targets the civilian market, it will definitely prioritize supplying the military if there is any demand!
"Won't this...lead outsiders to think that all our passenger planes are military-grade, thus leading to boycotts?" Old Lin was somewhat worried.

"How could that be? Boeing would be the first to object!"

Everyone smiled and nodded. Yes, cooperating with Boeing does have its advantages!

"By the way, our passenger planes come with built-in Beidou navigation terminals. The fact that a South Korean civilian airliner was shot down by the Soviets last time fully demonstrates that the existing navigation systems for civilian airliners are unreliable. An advanced satellite navigation system is essential, which will also promote the use of Beidou terminals."

Qin Liang nodded.

In fact, Qin Liang wanted to speak out as soon as the Sakhalin Island air disaster was officially announced.

Don't worry, everyone. As long as you install our Beidou navigation system, you'll never get lost!

but……

The first generation of Beidou, with its two-satellite positioning system, still has problems even after being expanded globally, such as...

Only satellites in geostationary orbit provide the best coverage of the equatorial region. Further north and south, the coverage is still acceptable, but the error increases after latitudes reach 70 or 80 degrees.

Therefore, to avoid being proven wrong, you shouldn't make excessive or careless statements!

There are too many lessons like this in later generations. When promoting intelligent driving, they exaggerate how amazing it is, but once an accident occurs, they quickly and honestly change it to assisted driving.

"It's time to start planning for the second generation of Beidou," Qin Liang couldn't help but say.

The first generation of Beidou, with its dual-satellite positioning, simply solved the problem of having or not having a satellite. The truly useful ones were the second and even third generations of Beidou.

The principle of multi-satellite positioning means that customers no longer need to send messages, making it simpler, more convenient, and less likely to expose the target.

"You Northwestern Polytechnical University are really rich! The first generation of Beidou was just completed, and you're already working on the second generation without stopping," Professor Lin said with a smile.

"If it can benefit all mankind, Northwestern Polytechnical University will do everything we can to make it happen."

At the same time, on the other side of the ocean.

Night had fallen over the land, but outside, the lights still shone brightly.

In a bar near the Pentagon.

"Hmph, when they come this time, I'll definitely ask them: a few years ago, we were only fighting the Jin family, but they got involved. What was their purpose?"

"Alward, you'd better not do that."

"Why, Tyson, are you scared?"

"Of course it's not fear. It's just... that falling out with them would be disadvantageous for us."

"Are we afraid of them?"

"Of course, after all, Qin Liang from Northwestern Polytechnical University is coming along this time. If we anger him... then all our cooperation with Northwestern Polytechnical University will have to be terminated. I don't know about other things, but at least Boeing's supersonic cruiser aircraft, which it has spent a lot of money to develop, will not be able to go into production."

"What? Boeing passenger planes need Northwestern Polytechnical University's support?"

“Yes, the fuselage is largely covered with composite materials, but the materials used domestically are defective and cannot be used yet… So, if you don’t want Steiner to complain, then…”

"He wouldn't dare! If Boeing dares to cause trouble, they can forget about ever developing another military aircraft!"

"They don't rely on military aircraft for a living. Do you think it's McDonnell Douglas? I heard that McDonnell Douglas is also eyeing the business in the East and wants to cooperate with them."

Boeing.

"Our supersonic cruiser has completed all its test flight courses and will be launched to the market as the Boeing 7E7!"

Steiner's statement drew criticism from a group of people below.

"E? ​​What does that mean?"

"It has many meanings, such as Efficiency, Economics, Environmentally Friendly, Extraordinary comfort and convenience, and E-enabled."

Steiner said a lot in one breath.

"My aircraft has a fuel consumption rate comparable to existing aircraft, but it can fly at near-sonic speeds, thus greatly saving airlines costs and passengers time. It is sure to be a hit! When the first production model starts production on June 10, we will officially announce this aircraft."

“This… On June 9th, an inspection team from the East is coming. Won’t they steal the spotlight?” Dick Taylor was a little worried.

“How could that be? Their planes are still being tested in their own country. This is an intercontinental route, so it’s definitely Boeing that should be the first to fly it,” Steiner said confidently.
