Seeing that the three units that study fixed-wing fighters have taken advantage of this cutting-edge aerodynamic exploration project to get their own aerodynamic pre-research projects for fourth-generation fighters, the 603 Institute in silence finally can't help it, why can all three of you units get the project, and I, the 603 Institute, can't get a foot in it.

Now I have indeed made up my mind that the 603 Institute will not continue to develop in the field of fighters and fighter-bombers, that is to say, this 603 will not participate in the war of the fourth-generation aircraft, but this aerodynamic exploration project is not necessarily only the fourth-generation fighter project, and other aspects can actually be studied and studied.

As the older generation of chief engineers sent by the 603 Institute, Chief Master Ma also put forward the project he was optimistic about: "Okay, the three of you are all going to develop in the field of fighter jets, so it is better for me to avoid this limelight, and the 603 Institute has always been a unit that develops large aircraft." In terms of passenger aircraft, there is probably not much need for much aerodynamic change, and it is like that over and over again, and breakthroughs have been made in supercritical wings and winglets. So, I'm going to apply for funding to study the aerodynamics of a large bomber with a flying wing layout, what do you think? ”

Is there finally anyone who can't help but pull away the aerodynamic exploration of the flying wing layout? This has reached the 90s, if there is no unit willing to make this request, I am afraid that Yang Hui will have to use his own strength to prepare to promote the development of this area, but fortunately, now 603 has stood up.

The aerodynamic layout of the flying wing, which in itself is not something worth keeping secret, after all, there is no such thing as a saying! The strange aircraft shapes that may appear in the world have been drawn by the Germans in World War II, so this flying wing is also a semi-public thing before the 90s, as long as you are engaged in aerospace, you still know what this thing is for.

And this clear knowledge is actually only limited to knowing that this kind of aircraft appeared in World War II, and it is also roughly clear about its advantages and defects, but if you really want to say that this thing is carefully studied thoroughly, no one in the republic at this time really dares to say this, at most, it is now that Chief Master Ma has put it forward like this, and he must be prepared to study this thing in depth.

It's still fast enough, and after the other few people discussed the situation, they finally spoke because of the chief teacher.

"I look at Lao Ma Ti ↓ dǐng ↓ diǎn ↓ small ↓ and say, .♂.o☆ s_ (); This project is feasible, the era of stealth aircraft is not only a fighter, but also an attack aircraft and bombers with a flying wing layout, such as the previous United States public -117, this guy has a fighter number, but it is definitely a conservative attack aircraft scheme with a flying wing layout. The excellent stealth performance of this aerodynamics deserves our attention, so I support the study of the aerodynamic layout of the flying wing, whether it is a twin-engine or a single-engine, a heavy bomber or a medium- and light-duty attack aircraft, we must study this aerodynamic layout. ”

This is a relatively broad scope, but the construction proposed by the chief engineer this time is actually a bit vague, and how can the flying wing layout be limited to the bomber field, this thing has great potential to be tapped, and it must be mentioned at this time.

No, General Manager Yang began to open his golden finger again: "The flying wing layout can indeed be used in large-scale manned bomber projects, but if this thing is only limited to the field of manned bombers, this is a big mistake, we have broken through the UAV control technology as early as the era of southwest science and industry, so the combination of flying wing technology and UAV is a new design, you can take a look." ”

Since it was time to talk about the flying wing layout, Yang Hui certainly didn't mind coming to diǎn to stimulate the fierce material, dragged out the moving small blackboard in the corner, and then began to draw a kind of aerodynamic design scheme that felt quite sci-fi just by looking at it, and with the outline of two or three lines, a drone with an orthodox flying wing layout appeared.

At a glance, this guy looked like a sword drone on the face of the Republic in the past, and at the same time, it has a highly similar aerodynamic shape to the French neuron and the British Thor drone, and for a while I really couldn't tell what it was, and in fact, Yang Hui himself didn't know which one he painted looked like.

"Look, if we use UAV design, cancel a variety of unnecessary airborne equipment while freeing up space, the original manned aircraft pilot's cockpit position can be installed air intake, so that the stealth performance of the aircraft is very helpful, and the shape is clean, there is no extra wing surface, I believe that such a stealth UAV can definitely have great potential, after installing the built-in bomb bay, the preset flight trajectory can achieve stealth penetration, launch a precise ground attack, This will be a much more advanced aerodynamic design than the American -117. ”

In line with the idea of how advanced it is, Yang Hui of course exposed the aerodynamics and design concepts of stealth drones such as swords and neurons in advance, so that everyone can pay enough attention to this project and know that the aircraft with flying wing layout has great potential to be tapped in the future.

As Yang Hui expected, the older generation of designers who participated in the meeting were stunned by this advanced design concept, the original flying wing aerodynamics can still be used in this way, the original stealth plus flying wing plus UAV can have such earth-shaking changes, this this Nima, this is not a turtle!

Of course, such a radical design is not without doubts, for example, Chief Engineer Lu saw the problem at a glance: "This kind of design is really good, and the required technology has begun to appear in the world, which means that from a technical point of view, this project can be completed." But we must understand that the reason why manned bombers have not been replaced by unmanned long-range cruise missiles and strategic ballistic missiles is that manned bombs have better mission flexibility, and they can cancel or change their missions at the moment before dropping bombs, but after replacing them with drones, the mission flexibility of manned bombers will also be greatly reduced. ”

Immediately afterwards, Chief Lu was actually taken by Yang Hui, and kept opening his mind: "If this is the case, we might as well directly develop a cruise missile with a stealth shape, as long as we want, the cruise missile can change or cancel the flight plan in the middle of the way, and this design seems to be simpler and cheaper." Of course, I don't think the wing layout plus stealth plus drone design is bad, in fact, we can design it as a reconnaissance aircraft without any problem, and I believe that this thing also has huge room for development. ”

Reconnaissance aircraft with flying wing layout, is this thing difficult?

From 20 years later, I said that this thing can also have a reference prototype: "Go forward, just change the layout of the flying wing of the sword UAV just outlined, this is another scheme, that is, the famous US imperialist-47B UAV, the biggest difference between this thing and the pure flying wing layout UAV is that the outer sweep angle of the leading edge of the wing is reduced, which is a typical aerodynamic layout of the stealth long-endurance unmanned reconnaissance aircraft."

In the aerodynamic design of the drone, the leading edge of the wing is actually more like a ****** layout, while the layout of the -47b is more like a double-****** design on the leading edge of the wing, and the ****** and the double ****** are naturally mentioned earlier. Naturally, the special flying wing design of the double-****** layout of the -47B is more suitable for use as a reconnaissance aircraft, and the facts also show that the two stealth unmanned reconnaissance aircraft of the United States, the RQ-170/180, use a double-****** wing-leading edge flying wing layout.

Therefore, when Yang Hui just changed the design, he heard Chief Lu praise sincerely: "Wonderful, such a design is really wonderful, this is the stealth unmanned reconnaissance aircraft I envisioned, yes, that's it." Old horse, see clearly, when you are exploring the aerodynamic layout of the flying wing, you must study this aerodynamic scheme well, I have a hunch that this scheme must be very promising.
