"Yes," as Chen Geng expected, with Chen Geng's question, the old man Giugiaro opened his bag and took out a folded drawing paper from it, and after opening it, there was a concept map in A0 format: "Gregory asked me to draw a picture for them, but I don't know much about aviation, so I drew a concept map casually." ”

Sure enough, it's a "concept",There are no parameters given above,It's similar to the concept of other industrial products we can see.,A few strokes,But through these few strokes, it has been able to show the general appearance of this product almost comprehensively,For example, this concept map designed by the old man Giugiaro is like this,Although it is still a concept map,But it already has the main features of the future PiaggioP180:

For example, the T-shaped high hanging tail;

For example, the wing mounting points of traditional aircraft are very different from those of traditional aircraft, which are basically installed in the middle of the fuselage, but in this concept drawing, the wing of this business jet is located in the rear of the entire fuselage, about a quarter of the rear fuselage, according to the porthole of the fuselage, the wing is located behind the entire crew compartment, and it is a mid-monoplane design that is impossible to see on any other business jet:

For example, unlike the ordinary propeller arrangement scheme, most of the aircraft that use propeller power have the propeller in front of the wing, but the aircraft on this concept diagram arranges the propeller backwards behind the wing, and combined with the wing that is installed very far behind, the position of the propeller blade is almost flush with the tail vertebrae of the aircraft.

But the real rarity of this concept map lies in its overall line design, which does not conform to aerodynamics, but as far as the lines of the aircraft are concerned, they are full and simple and smooth, which is different from the simple and rough American design, and the design of the entire fuselage looks like a literary style - this is the characteristic of Italy, and designers from other countries really can't learn it.

"Fernandez, what do you think?" said the old man Giugiaro's tone with a bit of ostentation.

"Very good," Chen Geng nodded admiringly, and it can be seen through this concept map that the old man Giugiaro really doesn't understand aerodynamics, or designed this aircraft based on the aerodynamic knowledge of the car, but it is already very good to be able to do this. He pointed to the wings and propellers on the concept map and said, "This wing and propeller arrangement plan is all about improving passenger comfort, right?"

Anyone who has ever flown on a plane knows that the most uncomfortable position is next to the wings and the rows behind the engine, and in terms of comfort, the more comfortable the seat in front of the wing, so the first class and business class seats are in front of the economy class.

Aviation enthusiasts who like airplanes and business jets should also find that in the field of civil aviation, although such as Boeing 737 and Airbus A320, the scheme of using wings to lift engines in the center of the fuselage, under a single wing and under the wings is recognized as having the best economy and easy maintenance, but almost all jet business jets still almost invariably use the "tail crane" that is not very convenient to maintain by installing the engine in the tail The solution (with the exception of business jets converted from large civil aircraft and the heresy of the Honda HondaJet) was designed to provide the most comfortable ride for the most comfortable passengers: maintenance and so on can be completely on the back burner compared to the comfort of the distinguished owner.

"That's right," as if he had found a guide, the old man Giugiaro suddenly nodded with a happy face: "These are all considerations to improve comfort...... Fernandez, I didn't expect you to understand aircraft design, you see, you see, what else needs to be modified?"

It was a bonus!

For Chen Geng's talent in industrial design, especially in automobile styling design, Mr. Giugiaro has no doubts, but Chen Geng not only understands design, but also can see the purpose of his design at a glance, which makes Mr. Giugiaro, a two-knife aircraft designer, have a feeling of meeting a bosom friend in a foreign country: You also understand aircraft design? hahaha...... Okay, okay, let's talk about it......

To put it simply, it is the happy mood of a stinky flag basket when it meets another stinky basket.

Do I know about aircraft design?

Chen Geng smiled: I said that I understand aircraft design, which is not wrong.

He was not polite, pointing to the concept map and said: "Everything else is good, but there is one point, this plane probably can't fly, or rather, it probably needs a runway that can take off the Boeing 737 to make this plane fly." ”

"Can't fly?" Hearing Chen Geng's words, not only the old man Giugiaro was stunned, but Grigory Biaggio was also stunned: "Why?"

Chen Geng: "First of all, the area of the wing, in order to be beautiful and smooth, the area of the wing is too small, so that the speed must be high enough to allow the front wheel of the aircraft to lift;

This is just a concept map, there is no detailed data, but if this aircraft insists on this design, I think the plane will have to reach a speed of more than 400 kilometers above the ground in order to take off, maybe more. ”

"It's a problem...... "Old man Giugiaro frowned.

He also has a wealth of aerodynamic knowledge, although it is just a low-speed movement of the car, but a lot of things are all bypassed, a little think about it to know that what Chen Geng said is indeed right, want to let such a plane fly, the initial speed is really high, the general propeller small aircraft, such as Chen Geng's King Air 200, the take-off speed is only 160 kilometers per hour, the take-off speed of jet fighters and large civil airliners is roughly between 260 and 280 kilometers, if the take-off speed of Piaggio's propeller-powered small aircraft is actually 400, it must not be laughed off？

Not to mention one of the most important features of a small aircraft: flexible take-off and landing and low requirements for the starting site, are also gone.

Grigory Piaggio's gaze fell on Chen Geng's body: "Mr. Fernandez, what can you do?"

"Won't it be hard?"

The old man Giugiaro pushes himself and others, and thinks that such an obvious problem must be difficult to solve: just like Italian sports cars, good looks are good-looking, and cool is really cool enough, but comfort and driving affinity......

To tell the truth, before the 21st century, the European sports cars represented by the horses and cattle of the Italian frame are naturally enemies with driving comfort and driving affinity, but people do this, you love to buy or not, and the beautiful name is that we are designed for people with certain driving skills and experience.

"It's not difficult," Chen Geng shook his head and said: "Anyway, it's just a concept map, and it hasn't officially entered the design stage, and if you want to maintain the taste of the concept map, you have to solve the problem, which sounds difficult, but that's actually what it's all about." ”

“......”

Old man Giugiaro's eyes widened: Is it really good for you to brag so loudly?

Grigory Piaggio's expression was no better than that of Mr. Giugiaro: Although our Piaggio family plays motorcycles, the motorcycle business is only a small part of our family business, and do you know that during World War II, our family also produced airplanes, and even produced our own aircraft engines, do you know why we dare to give such a propeller power scheme? is because our Piaggio family played like this before World War II, and we have a deep background and rich experience......

And then he soon became less "well-established and experienced......

"The best way to solve the problem is to increase the lift, the lift increases, and the requirements for take-off speed will naturally decrease," Chen Geng was really embarrassed to sell other people's things for money, so he simply said the solution of the P180:" If you want to increase lift, you can design the fuselage as a lifting body, and the fuselage will provide a certain amount of lift, then use more advanced wing design, such as a more efficient supercritical wing surface, and finally I recommend adding a set of canards at the nose position, which can significantly increase the low-speed take-off and landing performance of the aircraft......"

Lift body fuselage?

Supercritical wings?

Increased canard wings in the nose?

As these three plans came out of Chen Geng's mouth one after another, the eyes of the old man Giugiaro and Grigory Biaggio became more and more round: this kid really understands?

As soon as the expert made a move, he knew whether there was any, although Chen Geng's words were just on paper, but at least, he knew a little bit about aviation, Grigory Biaggio was completely relieved, he looked up at Chen Geng, and suddenly said: "Mr. Fernandez, are you happy to join us Piaggio Airlines? If you are willing to join, Piaggio will not only make this product, but also make the plane you told George before." ”

Is this an official pull yourself in?

Chen Geng is really a little excited, although the Italians are notoriously lazy and procrastinating, but it seems that the Piaggio Group is still relatively diligent in the P180 project?

He rubbed his chin and pondered for a while, and finally asked, "How much do I need to pay, how many shares can I have? What is my say in the company? And most importantly, how much are you going to spend on developing this aircraft, and when is it expected to hit the market?"

Grigory Biaggio was overjoyed and hurriedly said: "$20 million, you have 20% of the company's shares, George has $10 million, 10% of the shares, our family has contributed 20 million US dollars, the corresponding technology, personnel and our contacts in Italy have 40% of the shares, and the remaining 30% I am ready to leave for future partners, what do you think?"
