For Sirius, the design of the fourth-generation carrier-based aircraft is quite a challenging thing.

For Neptune, this is a hands-on realization of a plan that he already loves.

Both sisters wanted to know the results of the comparison between the two different design ideas, so after determining the goal, they went their separate ways and began to work hard to design the overall plan.

It took the two two days to complete the preliminary design plan, and by the afternoon of the next day, they had undergone a systematic evaluation, and the prediction and comparison results of different design plans were also out.

Mu Feng took Sirius and Neptune to look at the comparative data on the big screen in the scientific research center.

The land-based version of the J-20, the carrier-based version of the J-20, and the variable-swept wing version of the carrier-based aircraft, the three types of aircraft use exactly the same radar avionics flight control system, and Mu Feng identifies it as a modification of the same aircraft.

After the completion of the reverse engineering, using the design concept and production process of this world, the overall optimized land-based version of the complete body J-20 will be tentatively named J-20A.

The empty weight of the fuselage was reduced to 16 tons, the maximum internal oil reached 12 tons, the maximum load capacity also reached 12 tons, and the maximum take-off weight was 40 tons.

It can take off with full fuel and full ammunition at the same time, but as a stealth aircraft, it generally will not take off with a full load.

The highest performance air combat weight is about 26 tons.

The ultimate range is more than 6,000 kilometers, the combat radius is more than 2,000 kilometers, the supersonic cruise speed is Mach 1.8, and the maximum speed is Mach 2.8.

Avionics and stealth performance have also been optimized as a whole.

The carrier-based version of Sirius designed on the basis of the land-based version of the J-20A is tentatively designated J-21B.

Compared with the land-based version of the J-20A, the first half of the carrier-based version of the J-20B has changed relatively little, and the main adjustments are in the rear half and the main wing.

The main wing is extended outward, the wingspan width has been increased to 15 meters, and the sweep angle of the wing has been reduced accordingly.

The shape of the tail of the wing has changed, and the overall appearance is roughly M-shaped, folding upwards at the two upper nodes of the M.

The entire fuselage is completely integrated with the wing, and the rear half of the aircraft is somewhat similar to the flying wing structure of the B2.

The J-20B carrier-based aircraft is empty, with a tentative estimated weight of 18 tons, a maximum internal fuel of 12 tons, a maximum payload of 12 tons, a maximum take-off weight of 38 tons, and an optimal air combat weight of 26 tons.

You can't fill up with full fuel, and you can't fill up with full fuel.

The supersonic cruising speed is Mach 1.6, the maximum speed is Mach 2.6, and the combat radius is 2000 kilometers.

The variable-swept wing carrier-based aircraft scheme designed by Neptune is tentatively named J-20C.

The overall appearance resembles a fusion of F22 and F14, and is a further improved version of the AFX653 solution.

The J-20C carrier-based aircraft is empty, with a tentative estimated weight of 19 tons, a maximum internal fuel of 12 tons, a maximum payload weight of 10 tons, a maximum take-off weight of 38 tons, and an air combat weight of 27 tons.

You can't fill up with full fuel, and you can't fill up with full fuel.

The supersonic cruising speed is Mach 1.9, the maximum speed is Mach 3, and the combat radius is 1800 kilometers.

The performance of radar and avionics equipment of the three aircraft is exactly the same, and the difference lies in the difference in the performance of the airframe caused by different shape design schemes.

The best overall comprehensive performance is the land-based complete version of the J-20A, which can be said to be a real target model, and there is almost no room for optimization and improvement.

The problem is that she can't get on the ship, so she can only serve as the guardian of her own military port and land airfield.

The carrier-based version of the J-20B, most of the performance such as range and stealth is consistent with that of the roadbed J-20A.

The payload capacity, cruising speed, and maximum speed are slightly lower than that of the roadbed J-20.

Subsonic performance, low-speed performance, and maneuverability are slightly improved compared with the land-based version of the J-20.

The biggest advantage of the J-20C, the swept wing version, is speed.

She has the highest cruise speed of the three models, almost twice the speed of sound.

The variable swept wing design gives her a pretty good maneuverability at both high and low speeds.

However, the variable swept wing is at a natural disadvantage in terms of loading performance, and when it gives up stealth and turns into a bomb truck, the delivery capacity cannot be compared with the conventional layout of the J-20B.

Moreover, the number of available hardpoints is limited, and the position setting is not free, so it should be concentrated in the middle of the fuselage as much as possible, and at most extended under the wing box.

Another disadvantage is that the variable swept wing design cannot maintain full stealth, and can only choose a specific angle for stealth.

Neptune's stealth design for the J-20C is mainly aimed at the 68-degree sweep angle used in high-speed assaults, and the stealth ability is not lower than that of the J-20A and J-20B.

The second is the 20-degree sweep angle used for takeoff, landing, and low-speed cruise, which still has good stealth capabilities at this time, but is slightly lower than the J-20A and J-20B.

When cruising at other angles, the stealth ability is relatively average.

Aside from the land-based version of the J-20A, between the conventional layout of the ship-based version of the J-20B and the variable-swept wing carrier-based version of the J-20C, it can be said that there are mutual victories and defeats, and there is no imaginary one-sided situation.

Therefore, Mu Feng, Sirius, and Neptune are all a little worried, and they are now not sure which one to use as the target carrier-based aircraft in the future.

Neptune stretched out his hand and pointed to the carrier-based J-20B on the big screen and said:

"She has a strong payload ability, but they are all stealth aircraft, what's the point of having a strong plug-in ability? The built-in pylons are basically the same, with six medium-range bombs in the main magazine and two close-range combat bombs in the side magazine. ”

Sirius immediately said-for-tat: "For our current enemy, there is no absolute meaning whether or not to be stealthy, and there are many cases where you give up your stealth ability in actual combat and attack with all your might!" ”

Neptune immediately said: "If you give up the stealth ability, then your speed is far worse than mine, and this is not the limit design, my limit design should be able to achieve 2 times the speed of sound supercruise."

Sirius retorted again: "If you give up the stealth ability, your mount attack ability is not good, for our enemy, 1.6 times the speed of sound and 2 times the speed of sound is no different, my payload capacity here is also not the limit, if you continue to optimize, you should be able to take off with full fuel and ammunition!" ”

Mu Feng watched the two sisters arguing, so he pressed their heads one by one:

"Stop, stop, no need to argue, since the two designs have their own strengths, then we just want to do both, but we can't just keep it now, but continue to modify it by building on our strengths and avoiding weaknesses.

"Sirius, your J-20B, continue to strengthen the mount attack capability, expand the built-in magazine, and see if you can put anti-ship missiles into it, the goal is to squeeze out the 40-ton limit ejection capacity of our electromagnetic catapult, and the corresponding maneuverability and speed can continue to be abandoned.

"Neptune, your J-20C, continue to increase speed, reach 2 times the sonic cruise you said, further improve the maneuvering ability, the external payload capacity can be discarded, and the full-time air advantage aircraft, the canard wing design of the original J-20 can also be referred to if these capabilities are improved."

After listening to Mu Feng's words, Neptune and Sirius glanced at each other and nodded silently.
