Chapter 210: Those Things About Carrier-Based Aircraft


Of course, this is an earlier prototype, so it doesn't have a front wing.

At the time of the initial test, although the T10K-3 could land on the aircraft carrier, due to the strengthened structure of the aircraft, the empty weight was about 10 percent heavier than that of the Su-27, making its external weight only four tons.

Therefore, starting from the No. 05 machine, Su Sansan began to have a front wing, forming an aerodynamic layout of three wings.

Although this prototype is not a three-sided layout, it is a treasure for Chinese aircraft designers.

Except for the movable front wing structure, the rest of its structure is the same as the stereotyped Susansan.

Speaking of the three-sided wing, I have to say that although Su Sansan only added a small front wing, it played a great role in increasing the wing.

This small front wing, the angle that can be deflected is also very large, although it can not be differentiated, but through this small front wing, it works together with the side strip to form a favorable controllable vortex system on the wing of the aircraft, so that the lift coefficient is about 0.2 times higher than that of the Su 27.

Coupled with the digital fly-by-wire system, it has a very strong short-distance take-off and landing capability.

This three-sided aerodynamic layout differs from that of a canard aircraft, but makes full use of the front wings to create favorable vortices to improve lift and pitch control.

The duck layout of the aircraft design institute in southwest China is very good, and the later J-20 fighter adopts the duck layout, but it is the North Institute that presides over the J-15 carrier-based aircraft, and the North Institute is best at the three-sided wing layout, which is based on the Su 27, so in the bidding for a new generation of stealth heavy fighters, the plan of the North Institute is the three-sided wing layout.

In Shen Huan's memory, 98 was also an extremely important year for China's aviation industry, this year not only the first flight of the localized Su-27 and J-11 fighters was successful, but also the year when the bidding for the fifth-generation stealth heavy fighter was settled.

Of course, there is also the first domestic third-generation fighter J-10 independently designed and developed by China, which also made its first successful flight in March this year!

Shen Huan can also be deduced from the relevant literature that the time for the development of a high-mobility stealth heavy fighter was about ninety-one years, and then several domestic design institutes began to put forward aerodynamic schemes, and each came up with the final optimized aerodynamic layout, and among them, the design institute where Chief Zhang Hong was located also participated, but Shen Huan didn't know if he was involved, but these should be confidential, and Shen Huan would not ask.

Although Shen Huan is a shipbuilding engineer, because he is in a military industrial unit, he is also very interested in the military aviation industry and has studied it.

The J-15 carrier-based aircraft, which borrowed from the Su-33 carrier-based aircraft, is of course only a transitional carrier-based fighter, and with a stealth fighter like the J-20, it is bound to come up with a Chinese stealth carrier-based aircraft.

After all, in future naval operations, China's aircraft carrier aircraft formation is facing foreign F35 fighters, which are advanced stealth fighters developed by the United States.

Although the J-15 is powerful, after all, it is a generation behind, although the maneuverability is very strong, but in terms of battlefield situational awareness, it is impossible to compete with the fifth-generation aircraft, in the face of the F35 fighter, its combat exchange ratio can reach ten to one, that is, ten J-15 to one F35.

So Shen Huan asked Zhang Hong to do this this time this time, if China can get the Su-33 prototype a few years in advance, then the progress of developing carrier-based aircraft will be accelerated a lot in the future, so that the J-15 can build as few as possible, after all, it is only a transitional model, and the main force in the future is a new generation of stealth heavy carrier-based fighters.

Of course, in the stealth fighter scheme, the two biggest competitors are the North Institute and the Southwest Institute.

The plan of the North Institute is a new 93-type layout plan circulating on the Internet, as well as a three-sided wing layout plan with a front wing, which is the same as the relationship between Su Erqi and Su 33, because the North Institute is a plan based on the pneumatics of Su 27.

The South Institute is engaged in the scheme of the double-engine double-tail belly intake canard layout.

This is also the ultimate version of the canard layout that the South Institute has been committed to researching, through the development of the J-10 fighter, the South Institute has truly mastered this advanced aerodynamic layout, and the final result is, of course, that the plan of the South Institute has been recognized.

Due to the lack of combat capability and the leakage of information, the new 93 plan of the Beijing Institute should have been eliminated at the earliest.

Of course, the three-sided wing layout was also eliminated due to stealth problems, as well as insufficient supersonic maneuverability.

The Su-27 series of fighters, including the Su-33 carrier-based aircraft, have a huge flaw, that is, the problem of stealth, although this series of fighters is super maneuverable, but the radar reflection area is also the largest.

It is said that the radar reflection area of the Su-27 fighter has reached 12 square meters, but the F15 fighter of the same level is only about 3 square meters.

The J-20 is about 0.05 square meters, the F35 of the United States is comparable to the J-20, and the F22 can reach about 0.01 square meters.

Due to the addition of a front wing and at the same time to improve the directional stability, the height of the vertical stabilizer plane has increased slightly compared with that of the Su-27, so its radar reflection area is larger.

All of this is destined to be a J-15 carrier-based fighter that borrows from the Su-33, and it can only be a transitional model.

Whether this prototype can be brought back by the way depends on Zhang Hong and the leaders of the delegation, anyway, Shen Huan has done everything he can do.

This first day of visit still opened Shen Huan's eyes, and now he knows why Mao Xiong can compete with Mi Guo, because the strength of others is too strong!

The military industry that remains in a small member country like Vukran is much stronger than China in many areas.

Of course, the strongest is the engine, whether it is flying in the sky, swimming in the sea, or running on land, you can find strong products in Ukland, and these China can't make them at all now, so to pick up treasures in Ukland, it has become one of the things that China is most willing to do.

And in fact, it is also the case, China introduced GT25000 gas turbine from Ermao, which completely solved the heart disease problem of China's main destroyer.

In addition, diesel engines for main battle tanks were introduced, which gave rise to a new generation of domestic main battle tanks.

In the aviation field, the afterburner turbofan engine for the K8 trainer and the turbofan engine for the Falcon trainer were introduced from Ermao.

Of course, the turbofan engine used in the fighter was introduced from Da Mao.

However, in addition to the introduction of equipment and technology, China has also introduced a lot of talents, and it is the technical personnel of the Ermao military enterprises that have been lost that have greatly accelerated the technological progress of China's military industry after arriving in China.
