The one-piece frameless hatch, which is a standard for whether a fighter is fashionable or not even in the real world, now appeared in front of him out of thin air, making Long Yun feel a little unreal for a while.

After staying in a parallel world for so long, he has been busy fighting, or just tinkering with missile weapons, he really didn't know that the Soviet Union in this time and space still had such a high level of technical strength that it could come up with the integral hatch used by fighters, and it was also applied to the MiG-29 that was ready for mass production.

Not only that, the line of sight moved from the cockpit to the fuselage, and the intuitive feeling at first glance was the same, obviously the surface of the MiG-29N fuselage in front of you has undergone meticulous radar stealth treatment, and the exposed bumps and air intakes have completely disappeared; After staring at the side of the front plane for a few seconds, Long Yun concluded that the designers of the meter pattern must have modified the aerodynamic shape of the verification machine, because the sleek edge of the fighter in front of him had changed, and from the side, the outer edge of the edge seemed to have been repaired into a straight line.

Approaching the quietly parked MiG-29N fighter, Long Yun noticed that the gray coating on the surface of the fuselage of the aircraft was not ordinary spray paint, and it seemed to be a little matte roughness, and he threw an inquiring look at Krakow, who saw that Victor raised his hand to touch the touch, so he nodded to the major general of the air force:

"Ah, no problem, Comrade Major General, you can give it a try, the firmness of this paint is quite good."

"Really? It's really a kind of absorbing paint. ”

With the consent of the engineering personnel, Long Yun raised his hand and rubbed the smooth and neat front fuselage belly of the fighter, and he still felt the same coolness as far as he could reach. But the feel of spray paint with fighter jets is indeed quite different.

In order to minimize the strength of the electromagnetic signal reflected by the body. In addition to working the aerodynamic shape, the radar stealth fighter will also use absorbing paint to coat the surface of the fuselage. This measure can often reduce the reflection intensity of the radar signal by about 10 decibel on the basis of the original design, which is equivalent to the attenuation of the reflected signal strength to 10 of the original.

As for the MiG-29N in front of me now, I can't see what component of paint is used, but since there are such measures, it seems that the design requirements of this model are still relatively reliable. Thinking of this, Long Yun asked Krakow, but only received an ominous response, knowing that this designer also had a mission of absolute secrecy, he did not ask more, but snooped through guò consciousness to get the answer he wanted. The two MiG-29N are indeed coated with a ferrite hybrid absorbing paint, and the performance is similar to what I expected.

Raising his hand and stroking the skin of the fighter covered by ferrite paint, Long Yun noticed that the gaps in the interface of the MiG in front of him had been closed, according to the real-world radar stealth design, which probably shows that the radar stealth capability of the MiG-29N has approached or exceeded the level of 0.1 square meter of RCS?

But this judgment made Long Yun a little unbelievable, because he knew that fighters like MiG-29 and Su-27 had a design structure that was inherently unfavorable for radar stealth, that is, the engine intake duct that was almost completely straight from the front.

From the perspective of the electromagnetic signal reflection distribution of the fighter, the engine compressor exposed to the frontal vision, or the first-stage low-pressure compressor impeller. It is a very troublesome source of reflection - shouldering the arduous task of suction and pressurization, the compressor blades of the engine themselves cannot be made into a plane, but must be a curved surface with complex transitions; This foliar structure. It will cause uniform electromagnetic signal scattering in any direction, and because of the poor working conditions, it is not possible to suppress the signal reflection by means of paint and cladding, otherwise it will easily cause flight accidents once the paint peels off and is sucked by the engine.

It is precisely for this reason that in the real world where Long Yun is located, the Su-27 and MiG-29, two fighter families with many modifications, have never been like the J-10 and F-15 fighters, and there have been some improvements in stealth capabilities.

The reason for this is that in addition to the different understanding of the needs of air combat, the air intake hanging on the central lifting body is basically impossible to change, and the head-on RCS of the fighter cannot be reduced to a level with actual combat value, which is also an important factor; Due to the limitations of the innate design, no matter how well it is modified in other aspects, it is difficult to make the Su-27 or MiG-29 into a usable radar stealth fighter.

But now, in this bizarre parallel world, the Mikoyan / Grevich Aircraft Design Bureau has come up with a "low detectability" MiG-29, isn't this a strange thing?

Seeing the stealth MiG-29N fighter with his own eyes, Long Yun's doubts were not completely solved, he subconsciously stared at the air intake of the fighter in front of him for a while, and then slowly realized that the air intake cover of this gray MiG machine seemed to be a little extraordinary, why did it not look like the common dark red, but it was the same light gray as the body.

The same gray gradient paint, presumably with a layer of absorbing paint on top of it, but what's the use of doing this, isn't it......

Could it be that the cover is not removed until liftoff - to cover the engine compressor wheel?

Suddenly, his head was on this string, Long Yun tilted his head to look at Mikhail Krakow as if he suddenly realized, and saw a trace of cunning flashing in the latter's eyes, he suddenly felt that his mouth suddenly opened, he clapped his hands next to the plane, and his mouth couldn't help but let out an exclamation.

These old hairy people, their thinking is really unusual, they can still come up with this way!

Suddenly realizing what was going on with the MiG-29N's air intake, Long Yun bowed down and went closer to observe, and sure enough, he found that the structure of the two cover plates covering the wedge-shaped air intake of the MiG's belly was not ordinary, and it looked like it should be the kind of design that could be opened and closed, and the shape design of the air intake was also different from that on the original MiG-29, which seemed to be kept closed during normal flight, and could only be opened at certain times.

Seeing such a design, Long Yun was even more convinced of the MiG Design Bureau's thinking, and he felt that the thinking of these scientific research workers was indeed very powerful: according to their ideas, the gray fighter in front of him may not be able to be called a real radar stealth fighter, but if it is not used to fight air battles, but to perform some special tasks, it is estimated that it can still be competent.

The engineers of the MiG Design Bureau, who chose the MiG-29 as a demonstrator for the "low detectability" project, probably also took into account the problem of the air intake from the very beginning.

Very familiar with the fuselage structure of this fighter, the designers made full use of the shutter-type auxiliary air intake on the sleek and large side strip of the MiG-29 fighter, and the way they dealt with the exposure of the intake blades was so simple, but it had a good effect, that is, the MiG-29N used the auxiliary air intake all the time when performing combat missions, and the main air intake was completely closed by the lowered cover at this time!

This way of flying, Long Yun just thought of a possibility, he himself has never tried it, but according to the analysis report seen in the real world, VVS really did this aspect of the actual yàn, the results confirmed that the MiG-29 can rely only on the auxiliary air intake, in the medium altitude airspace to fly out of Mach 0.85 amazing speed - of course, this is only limited to the route of level flight, engine combustion efficiency, acceleration and the like can not be expected, as for maneuver air combat is even more impossible, A simple maneuver would have shut down the two RD-33 engines.

Seeing that the design of the rice pattern was so unexpected, Long Yun suddenly had more confidence in the combat capabilities of the MiG-29N, he slowly walked around the two gray fighters in the hangar for a circle or two, and understood the processing details of the entire fighter, and also noticed the change in the lines of the abdomen of the body.

"That, Comrade Krakow, how come the left and right air intakes of this MiG are almost filled? ――Is it an integrated fuel tank? ”

Speaking of the exit, Long Yun himself thinks that this is unlikely, although this kind of conformal fuel tank-like installation is conducive to stealth, but looking at the poor paper range of the MiG-29N, this aircraft is already good without reducing fuel, how can there be any overall fuel tank?

However, contrary to his thoughts, Krakow, who heard this, nodded to Long Yun, "Yes, it can be filled with some more oil; The design principle of stealth fighters is to fill more fuel, and this design of ours is even more so. ”

"Ah...... Is it? But what do you think of the fact that this type of fighter has such a short range? ”

As he spoke, he and Krakow pulled the flatbed block in the hangar, and Long Yun was now more curious about the belly structure of the MiG-29N, and he wanted to lie on the pulley to take a closer look.

If it is really according to the engineer, there is an integral fuel tank installed, then he thinks that this design is not too clever - you must know that the so-called "central lifting body", "the best aerodynamic configuration of the twin-engine fighter", the "ditch" between the air intakes under the lifting body plays a lot of roles, and the Su-27 fighter has also had some plans to add conformal fuel tanks here, but it has not been adopted because of the impact on flight performance.

So now, the personnel of the MiG Design Bureau have to use their brains here again, and the smaller MiG-29 must have a greater negative impact, is it really okay to do this-

- Oh, oh!

I see, that's it! (To be continued......)
