The J-20B was changed to a carrier-based attack aircraft, and the tentative model is "J-20B".

From the very beginning, Mu Feng knew that the new carrier-based aircraft was redesigned using the technology of the J-20, an almost brand-new aircraft, and basically did not retain much of the characteristics of the J-20.

Now the appearance of the new aircraft in front of me really has no resemblance to the land-based J-20A.

The shape of the plane as a whole resembles an isosceles triangle, but the two waists of the triangle gradually narrow inward, turning into two smooth arcs, somewhat like a ginkgo biloba.

Compared with the land-based version of the J-20A, the fuselage of the carrier-based attack aircraft has been significantly widened, and the distance between the two air intakes has also been significantly increased.

The rear half of the fuselage is a flying wing structure similar to that of the Rainbow 7 and B2, and the tail is in a large zigzag shape.

However, the ends of the wing can be folded upwards, and there is no horizontal tail, but the vertical tail is retained.

The thickness of the fuselage has increased significantly compared with the original J-20 land-based version, and from the nose or tail direction, the fuselage has become significantly more rounded and plump.

J-20's nickname is Weilong, and Mu Feng feels that this guy can be called a fat dragon.

The two engines of the land-based version of the J-20A are next to each other, and the redesigned J-20B carrier-based attack aircraft of Yuanwang 7 is 1.6 meters apart.

The spacing between the two engines of a twin-engine fighter affects the drag experienced by the aircraft in flight.

In supersonic conditions, drag is minimal when there is no spacing between the engines.

As the engine spacing increases, the drag increases, reaching its maximum at about 0.5 engine diameter spacing.

However, after the distance exceeds 0.5 engine diameters, the drag decreases again.

After more than 1 times the engine diameter, the flight resistance drops to near no spacing.

Therefore, for supersonic aircraft, the spacing between the two engines is either not there, or the spacing is at least double the diameter of the engine.

The increase in engine spacing will affect the rolling performance of the fighter and affect the agility of the fighter.

Therefore, the new generation of fighters are basically narrow-pitched, such as J-20 and F22

But wide engine spacing, which means a wider body, means a larger built-in magazine.

And this is what bombers and attack aircraft need most, and the maneuverability does not need to be to the limit.

Therefore, for the design of the carrier-based attack model, Mufeng and Sirius chose a large engine spacing at the beginning, and after the Yuanwang 7 came, this setting was still retained.

In the end, the J-20B carrier-based attack type has two large main bomb magazines in the front and rear under the belly.

The first main magazine is located in the middle of the fuselage, with a width of 3.6 meters, a length of 5 meters, and a depth of 0.8 meters.

The second main magazine is located in the middle of the engine, with a width of 1.6 meters, a length of 5 meters and a depth of 0.8 meters.

On the outside of the air intake, under the wing, there were two more small magazines on the sides.

Because the body becomes rounded, the slope on the outside of the air intake becomes slower.

The Yuanwang-7 widened the original two small magazines on the sides, and the original capacity of carrying one air-to-air missile on each side has now become two on each side.

After the overall redesign, the stealth performance is not weaker than the original land-based version of the J-20A.

The final specific parameters of the J-20B carrier-based attack type are:

The length of the fuselage is 20 meters, the wingspan is 15 meters, and the wings are slightly wider than the J-15 when folded.

Supersonic cruise speed 1.4 Mach, maximum speed 2.4 Mach, maximum range 6000 km.

The empty weight is 16 tons, the built-in fuel is 12 tons, the maximum payload is 12 tons, and the maximum take-off weight is 40 tons.

Then, according to the original plan, several built-in ammunition were specially developed for stealth carrier-based aircraft.

Mainly anti-ship missiles and guided bombs, the purpose of the design is to shrink the wingspan as much as possible, shorten the length, so that it can be completely put into the built-in magazine, as far as possible to achieve all the built-in mounting.

The first is the YJ-12 built-in missile, with a range of 300 kilometers, a maximum speed of 3 times the speed of sound, a weight of 1600 kg, and a diameter of no more than 60 cm after all the wings are folded.

The large main magazine in the middle of the fuselage can be loaded with 4 pieces, and the main magazine in the middle of the engine can be hung with 2 pieces, and a maximum of 6 bombs can be carried at one time.

Then there is the YJ-83 with a built-in missile with a range of 150 km, a maximum speed of 2 times the speed of sound, a weight of 800 kg, the wings are almost completely folded, and the final diameter does not exceed 40 cm.

The large main magazine in the middle of the fuselage can carry 8 pieces, and the main magazine in the middle of the engine can carry 4 pieces of shoelaces, and a maximum of 12 pieces can be carried at one time.

Then there are bombs of various sizes, including 2000 kg, 1000 kg, 500 kg, 250 kg, 100 kg classes, with a guided version and a normal version.

With these special ammunition, the J-20B carrier-based attack aircraft has achieved a 12-ton mount all built-in.

Both anti-ship missiles and guided bombs, in order to be as built-in as possible, have to have as much of a constricted wingspan as possible.

However, in order to launch and start quickly, the wingspan of air-to-air missiles is still unconstrained.

However, the air-to-air missile itself is lightweight, only about 200 kg.

If all magazines carry air-to-air missiles, up to 18 medium-range bombs and 4 close-range combat missiles can be installed, for a total of 22 air-to-air missiles.

All magazines can be replaced with fuel modules, and the side magazines can be replaced with larger cannon magazines.

By default, there are two 20mm cannons with 512 rounds of ammunition, which can also be replaced with fuel modules.

The large central bomb magazine of the aircraft, which can be equipped with an electronic warfare module, can be transformed into a stealth electronic warfare aircraft.

It can also install an early warning radar module, and four fighter jets can be networked to temporarily act as early warning aircraft.

Mu Feng looked at the various parameters of this aircraft, as well as the way various ammunition were matched, and felt a little overwhelmed.

In the process of designing the aircraft, the crew-related facilities were eliminated and the integrated molding technology was applied.

Coupled with some trade-offs for attack aircraft models, the empty weight of the carrier-based attack aircraft was finally pressed to 16 tons, which was consistent with the land-based version.

The maximum take-off weight is 40 tons, which is to squeeze out all the performance of the existing electromagnetic catapult.

After replacing part of the built-in magazine with a fuel tank, the range of 6,000 kilometers can be further increased.

With a maximum bomb load of 12 tons, it can be said that it is a well-deserved aerial bomb truck.

The key is that she is still a stealth fighter, and after dropping the bomb, she can cruise at supersonic speed.

It is conceivable that her combat method should be to fly over the target with stealth in secret, drop the bomb, immediately accelerate to 2 times the speed of sound and leave the scene, and then maintain supersonic speed to return to the mothership.

Because it is fatter, the mobility is relatively weak, but it depends on who you compare it with.

Compared with the land-based version of the J-20, of course, it is slightly weaker, but it is still stronger than the 3rd generation aircraft.

Nominally designed as an attack aircraft, she can carry 22 air-to-air missiles out of the house, using stealth, speed, and maneuverability to continuously kill third-generation aircraft.

Now it seems that she should be called not an attack aircraft, but a "stealth fighter-bomber".

After a general understanding, Mu Feng gave her a code name, "Flying Bear".

The white tiger has wings for flying bears.
