It was no wonder that the people present were so surprised, the plane behind the curtain was beyond everyone's imagination.

The thick nose is extremely heavy, giving people a sense of stability, and then the high pop bubble cockpit is high and maneuverable.

The cockpit is flanked by wide wings, different from the traditional trapezoidal rear wing of the traditional advanced trainer aircraft, the aircraft wing in front of you is slightly complex, starting from the lower end of the cockpit is two very powerful side strip wings, which extend to a pair of swept delta wings, and then have a front angle in the middle, forming a pair of small delta wings again.

The result is a unique combination of wings and double delta wings, and with the fuselage that seems to be integrated, the whole aircraft looks like a bird with open wings from the front, as if it can soar into the sky with just a flickering wing.

Of course, if this is all there is, professionals such as Mareshevsky and Merlinz may be surprised, but they will not be shocked, and they cannot control their emotions because the wings of the aircraft are not only elegant, but also the front and rear flaps and ailerons equipped on the double delta wings.

The leading edge ailerons on both sides of the wing are not left alone, and in addition to the traditional ailerons, there are a bunch of fuller-style flaps at the rear of the wing, which, together with the upturned spoiler, immediately highlights the advanced nature of this pair of wings.

As the saying goes, the layman looks at the liveliness, and the insiders look at the doorway.

Maresevsky and Mellinz and others are not only looking at how powerful and domineering this pair of beautiful wings is, but through this pair of wings, they can intuitively feel the basic performance of the Jianjiao 7Max in front of them.

One word: excellent.

Regardless of the others, the layout of the side strip wing and double delta wing makes the J-7Max's hovering and small-radius turning performance at medium and low altitudes no less than that of early third-generation fighters such as F-16A or MiG-29A.

As for the speed, not to mention, the layout of the side wing and the double delta wing gives the Jianjiao 7Max excellent medium and low-altitude performance, and it is also very strong in terms of supersonic speed, of course, the unique structure of the double delta wing, which has the disadvantage of increasing drag, resulting in the maximum flight speed of the Jianjiao 7Max is difficult to exceed Mach 2.

At most, it is about Mach 1.5, but the problem is that the Jianjiao 7Max is just a high-level training aircraft, and the maximum speed of Mach 1.5 has killed an early high-level training aircraft, not to mention that the combat reverie of the third-generation aircraft is not known for its high-altitude and high-speed, so the speed of Mach 1.5 is not only sufficient, but can even be used as the main combat aircraft in some weak and small countries.

And that's just part of the wings that give the J-7 Max excellent performance.

In addition to the layout of the side strip wing and double delta wings, the flaps, ailerons, spoilers and other structures on the wing enhance the maneuverability of the J-7 Max, while also giving the aircraft an unparalleled ability, that is, excellent short take-off and landing capabilities.

It is important to know that both fuller-type flaps and wing spoilers are mechanisms on large passenger aircraft, which function to increase lift during take-off and shorten the landing distance when landing.

The big guy with a take-off weight of hundreds of tons can easily control take-off and landing by relying on this set of mechanisms, and a training aircraft of less than ten tons is naturally immediate, with the stout first three landing gears under the belly, the Jianjiao 7Max's super simple field airport short-range performance is about to come out.

This is too important for an aircraft, indicating that the aircraft is extremely adaptable, leather, durable, and resistant to manufacturing.

Of course, these alone are not enough to show that the aircraft is excellent, if there is no bilateral rectangular air intakes under the wing, the tall vertical tail of the tail and the full motion horizontal tail on both sides of the cooperation, it can only be said that this aircraft is general, but these things can be added like the finishing touch, so that the whole aircraft exudes the brilliance of a generation of famous aircraft.

In addition, to the silence of Mareshevsky, Merlinz sighed that the Jianjiao 7Max looks small, but it has reserved a very large redundancy for improvement.

Not to mention the rest, but the huge nose fairing directly in front of it is much larger than the diameter of the F-5 fighter equipped by Thailand, and almost the same as the nose diameter of the Mirage 2000 fighter equipped by France.

This shows that the Jianjiao 7Max can be equipped with a more powerful fire control radar or other advanced avionics equipment, so that the Jianjiao 7Max has more advanced teaching or combat capabilities.

There are many similar places, and after a cursory glance at the professionals present such as Mareshevsky and Merlintz, they found that there were as many as four or five, and so many things add up, and it is difficult for Mareshevsky and Merlinz not to be shocked unless they are aliens visiting the earth.

"Great Lenin, the Chinese comrades I brought out are now so advanced in aviation technology?"

Looking at the Jianjiao 7Max that was about to fly under the spotlight, Mareshevsky was stunned for a long time, and then sighed in a low voice, yes, Malenshevsky felt that the technical level of the Jianjiao 7Max in front of him was high, even surpassing the Yak-130 that they had been developing since the Soviet era.

Not to mention the rest, this time to participate in the bidding for the Thai trainer aircraft, they only brought design drawings, technical descriptions, a full-scale wooden model, and a video footage of the Yak-130 test flight at the beginning of the year.

And Tengfei Group not only handed over the Chujiao 6pro to the crown prince of Thailand to enjoy himself in the sky, but also the Jianjiao 7Max displayed as a new machine in front of him is not a full-size model, but a mass-produced real machine that can fly into the sky at any time.

One is an ethereal concept, and the other is a real guy, who is higher and which is lower, and who is strong and who is weak.

Of course, the problem is that the Yakovlev Design Bureau's pockets are cleaner than its face, and soon after the first flight of the prototype that was tested at the beginning of the year, it could not afford the cost of subsequent test flights, and in addition to the lack of follow-up maintenance, it was already unusable like scrap metal.

So even if Yakovlev wanted to send it, he didn't have to send it, of course, even if he really sent a Yak-130, it could really overpower the Jianjiao 7Max?

Maybe before he saw the Jianjiao 7Max, Mareshevsky still had some confidence, but when he saw the Jianjiao 7Max, he beat the drum suspiciously.

Although there is only a high-level training aircraft in front of him, Mareshevsky can get a glimpse of the technical background of the Tengfei Group in aircraft design and production.

Among other things, the ability to integrate the intricate Fuller-style flaps and wing spoilers of a large airliner into the wings of an advanced trainer aircraft is rare in the world.

What's more, after the design is completed, it will be manufactured, you must know such a complex wing structure, but there are almost changes in materials, processes, controls, and experience~~ state requirements, in addition to this, we must try to reduce the cost, after all, if the training aircraft is not cost-effective, why should various countries use it to train pilots, and directly drive combat aircraft.

Such a balance is extremely difficult for any aircraft manufacturer to achieve, and Ascendas seems to have found a delicate balance between complex high-tech and low cost, because the sign on the front of the Jianjiao 7Max prominently says that the unit price is 9.98 million US dollars.

All this shows that the Ascendas Group has surpassed the Yakovlev Design Bureau in some respects, and this is the reason why Mareshevsky is extremely shocked.
