"Oh?" Marcel is very curious, now, although the Mirage 4000 has been claimed to have strong combat capabilities, but the specific data is still confidential, or rather, some data is still in test flights, and the person in front of him seems to know his own aircraft very well.

"Sir Qusay, you seem to be very familiar with our Mirage 4000?" Marcel asked.

I can't talk about familiarity, but Zhang Feng still understands the advantages and disadvantages of Dassault aircraft.

"Your Phantom 4000, like the Phantom 2000, adopts both sides of the air intake, tailless delta wing layout, although this layout is what your company is best at, but, compared with the conventional layout, the most obvious defect is that although the high-altitude high-speed surname can be very good, but the low-altitude maneuverability is not very high."

"Our air show today doesn't mean that our planes have a high level of maneuverability?" Boileau said.

"With all due respect," Zhang Feng said, "today's is just a performance, and those actions such as tail rush are very well done, but this is just a prototype that does not have any other equipment installed, and I'm afraid I don't have enough fuel, right?" If you really put four medium-range air-to-air missiles and four short-range combat missiles on it in actual combat, can you still do so many maneuvers? ”

Boileau was speechless for a moment, but he also knew a little about these performances, and when it came to actual combat, some actions might only be done once in a lifetime.

"Although your fighter jets have adopted a relaxed static and stable and fly-by-wire system, the maneuvering surname of the Mirage 2000 is much higher than that of the Mirage 3, but the American F-16 and F-18 aircraft with large side strip wings and wing-body fusion are also very good, so I need an aircraft that completely outperforms them, not only in medium and high altitudes, but also in close combat, it can completely defeat the opponent, I need more advanced technology!" Zhang Feng said.

Zhang Feng said a little quickly, and Miss Sarah, the half-baked translator, did not translate these professional terms accurately, but Marcel had already heard the other party's meaning clearly.

This is also a problem that has plagued Marcel for a long time, Dassault is best at the aerodynamic layout of the delta wing, so, although the Phantom F1 adopts the conventional aerodynamic layout, however, the surname can not be improved much, which also returns to the old road of the delta wing, the delta wing layout, the aspect ratio of the wing is relatively small, and it is convenient to set up more pylons under the wing, however, the defects of the delta wing make its medium and low altitude surname energy is not excellent, and the take-off and running distance is relatively long.

Listening to the other party like this, it seems that a solution has been found? Marcel came interested, and it would be great if the other side really had a way to solve it. However, I don't think I've heard of Mr. Cusay's study of aerodynamics, right?

Although Zhang Feng has not learned, he has seen it, in later generations, among the several main fighters, the EF-2000 jointly developed by Europe, the Rafale of France, the Swedish Gripen, the motherland's Jian-10, and the Mikoyan's MiG-1.44 that the Soviet Union failed to put into production, these fighters all use a canard aerodynamic layout.

The canard aerodynamic layout, in fact, is based on the delta wing, and a pair of front winglets, called canard wings, are added, like a standing duck. In this way, the vortex generated by the front wing can be used to increase the lift of the rear wing several times, which greatly expands the maneuverability of the aircraft, and the full front wing is still a control surface, and the biggest benefit is to directly obtain the head-up torque, or the positive lift, the fighter equipped with canard wings, short run, and large angle of attack take-off can be very good.

Zhang Feng is now going to sell this thing, I guess at this time, their researchers are already exploring, right?

In fact, the layout of canard wings was discovered by the Swedes as early as 1966, but there was no such control as a telex system at that time, and it was difficult to control canard wings.

"Your Excellency Qusay, do you have a more appropriate method?" Marcel asked.

"Mr. Marcel, these 70 million fighters are really expensive, you can equip me with five F-20s, you say, I have five F-20 fighters, can I shoot down a Mirage 4000?" Zhang Feng asked.

"This is a bit expensive, so let's be sixty million!" Marcel said, "What did you just say? ”

"Oh? Did I just say that? I was talking about the F-20, 60 million? That's four, it seems, I still have to make an assessment, four F-20s besiege a Mirage 4000, and you have to fly to know it! ”

"Your Excellency, you are like this, it only makes me doubt your sincerity." Marcel finally couldn't help it.

"Okay." Zhang Feng said: "Mr. Marcel, have you ever thought about what would happen if you installed two small wings in front of the wings of the Phantom 4000?" ”

Putting on little wings? Marcel felt that this statement was very interesting, but he did not understand what Zhang Feng meant.

Fortunately, Boileau took out a model of the Mirage 2000 and handed it to Zhang Feng.

Zhang Feng pointed to the front of the wing and said: "Here, installing a pair of small canards can strip the air from the upper surface of the wings and obtain greater lift, which is much better than the effect of the leading edge maneuvering flaps, and such canards can be deflected in this direction when taking off to directly provide lift." Zhang Feng said while gesturing.

Boileau was a layman, and he was only concerned with sales, but he still didn't understand, but Marcel understood, and his eyes began to shine.

Yes, really good, in this case, you will directly get positive lift, then, a short take-off is definitely not a dream, maybe you can take off with only a runway of three hundred meters! And what the other party said to get more lift is not too sure before doing a perfect wind tunnel experiment, but it makes perfect sense depending on what the other party said.

(The so-called positive lift, only the normal layout of the aircraft, if you want the nose to rise, then you need to rotate the tail, let the air deviate upward, press the tail down, that is, press the tail down, so that the nose can be lifted, this is called negative lift, in the middle, there will be a loss of energy, and the canard wing is in the front, let the air deviate downward, directly lift the nose, this is called positive lift, so, canard aerodynamic layout, also known as head-up layout.) ）

"The Mirage 4000 needs to redesign the flight control laws, the front full canard wing is also designed, and the wind tunnel experiment needs to be re-conducted, but I think it's definitely worth redesigning your company." Zhang Feng said.

Marcel quickly calculated in his mind, although it was said that he would have to go through a wind tunnel to know, but if he could really succeed, then he would definitely be able to take the combat effectiveness of the Mirage 4000 to a higher level, that is, in the face of the F-14 with variable sweep wings, it would definitely not be at a disadvantage in close combat.

"50 million dollars a plane, 40 million parts, 15 million engines and radars, in this case, I still have some ideas, I want to talk to Mr. Marcel." Zhang Feng said.

Zhang Feng didn't know that Sarah, who was acting as a translator next to him, was already looking at him with adoring eyes.

Qusay, who is simply an all-round talent, can fight, has resourcefulness, and even bargains, he is so ruthless, cutting down 20 million US dollars, which is not a small amount.
