However, now, looking at the "No. 10 Project" in the parallel world, Long Yun probably realized that since the Su-27 fighters and equipment units of PLALAF and Plana are close to 300, in the context of military struggle in the new era, the traditional air defense combat needs are no longer very urgent, and when designing and developing a new generation of domestic fighters, the 601 Institute will definitely have some new ideas.

In other words, with Long Yun's understanding of the pace of development in the real world, it seems that the motherland in the parallel world is the same, trying to build the "No. 10 Project" into an all-round fighter, which is the real consideration of the relevant units.

Single-engine medium-sized multi-role fighter, the typical representative may be the American F-16, this kind of development was deeply influenced by the "fighter mafia", known as a fighter built purely for air combat, from the service in the USAF engaged in the most is not air combat, or a narrow sense of air supremacy, but ground attack, air interdiction and even tactical reconnaissance, this trend, obviously by the "No. 10 Project" designers have paid attention.

Because of this, think about the real world J-10A "Raptor", the fuselage design has some measures to improve flight performance, in addition to the overall configuration of the canard wing design, the reverse twist of the inner half of the wing is also one of the highlights, but limited by the technical level, more importantly, the tactical needs of the military, the stereotyped J-10 fighter is still biased towards air superiority, and other capabilities are only at the middle and lower level in the third-generation aircraft family.

The reality is that the overall design of the J-10 fighter in the parallel world has not departed from the large framework of the "No. 10 Project", and the outline is also very similar, but if you look closely, you can still find some clues.

Compared to the real J-10A. The J-10 fighter in the parallel world, the first big difference is the air intake design, the iconic adjustable inclined plate air intake of the A type aircraft is replaced by a more concise structure, which looks a bit like the kind used by F-22, F/A-18E/F and other models, which brings Long Yun's first impression. The maximum speed of this "Raptor" fighter should be lower than that of the A-type, but the corresponding structural and weight costs in the air intake tract are also lower.

In addition, there is another point that is not easy to see when standing on the ground, and Long Yun only noticed it through the guidance of the Chinese comrades.

Compared with the A-type "Raptor", the gray fighter in front of him has a wider wingspan and a larger main wing area, while the canard wing area is relatively smaller. The position is also further back.

In Long Yun's view, according to his limited knowledge of aerodynamic configuration, the design of the J-10 is a little similar to the French "Rafale" fighter, which is commonly known as the "close-coupled canard layout", compared with the original J-10A. The agility of this "Raptor" is slightly reduced, but it has better loading conditions - not only the lift characteristics are better, but the main wing is also easily positioned to arrange pylons, and the weapon loading is less restrictive, which can be seen as a multi-purpose service.

The air intake and wing arrangement are the main components of aerodynamics for a fighter, and after two circles around the J-10 fighter with his colleagues, Long Yun made more discoveries.

Take a look at the shape of the fighter. He felt that the "Raptor" in front of him was really a little similar to the J-10E "Villain" he had piloted in the Middle East before, and the shape of the vertical tail was relatively similar. The two pelvic fins on the tail brace are also missing, and it does look like some compromises have been made on top speed.

In addition, some details have been changed, such as the use of the oblate nose section of the J-10B fighter in the real world, the increased downward viewing angle is helpful for the field of view when attacking from an air-to-side surface, and there are some minor differences. Look at it as a whole, and then climb the stairs to enter the cockpit for a while. Long Yun was quite surprised to find that it was different from the first impression of simplicity and low-key. The overall technical level of this J-10 fighter with fuselage number 01341 is quite advanced.

At the very least, it is stronger than the J-10A that was only declassified at the beginning of the 21st century in reality, and perhaps in addition to some indicators such as the maximum level flight speed at high altitude and the instantaneous disc angular velocity, the performance will be better than that of the A-type counterparts in another world.

A kind of successfully designed multi-role fighter, this is probably the first impression left by the "Raptor" on Long Yun, he then looked through the technical information provided by the Chinese personnel, although he did not know how accurate it was, but saw that the J-10 fighter with a significantly smaller body marked with a maximum bomb load of 8,000 kilograms, that is, an astonishing eight tons, since it is not a military trade occasion and there is no need to fake, he raised his eyebrows to express his surprise.

Indeed, he has reason to be surprised, this number is much stronger than the J-10A in the real world.

J-10A "Raptor", check the information on the Internet, many pages indicate that its maximum bomb load is seven tons, this figure is basically the maximum take-off weight of 19277 kg minus the use of empty weight and internal oil, it looks quite spectacular, in fact, it is not the case at all.

The bomb load of a fighter is an important indicator of combat performance, but there are many ways to calculate it, and there are also many possibilities for exploiting loopholes.

For example, the maximum take-off weight of the fighter (this figure mainly depends on the maximum ground clearance speed and ground clearance capacity of the fighter design) minus the empty weight and internal oil, so that the "bomb load" obtained is almost the most considerable, and according to the typical air superiority load, the cumulative bomb load when not hanging the auxiliary fuel tank is the smallest, and the gap between the two can be more than doubled.

Compared with the J-10A, a typical example is the Su-27SK installed in the Chinese Air Force, and the maximum bomb load column sometimes says "4000 kg", which seems really useless, but in fact, this number is just the total weight of four R-27ER, two R-27R/T, four R-73 missiles plus pylons.

If you take into account the large internal fuel of the Su-27 series fighters, when performing tactical bombing missions, the equivalent conversion of the Su-27SK and F-15C fighters, the former is equivalent to being able to carry a total of about 11,500 kilograms of aerial bombs and fuel, while the latter wants to achieve the same combat radius, the 7,500 kilograms of bomb load also includes auxiliary fuel tanks weighing at least four tons - so calculated, in the event of an attack on a target at a distance of a thousand kilometers, one Su-27SK is capable of delivering more than twice as many aerial bombs as the F-15C.

Although the main task of the fighter is not to attack from the air-to-side surface, it can also be seen that the bomb load of the fighter is actually a performance parameter with a lot of water, and it is meaningless to simply compare the numerical size of different models.

Back to the situation of J-10, 8000 kg of bomb load, Long Yun intuitively thinks that it is basically credible, and consciousness snooping has also obtained some information, indeed, the configuration is closer to the multi-role fighter "Raptor", the wing leading edge sweep angle, wing area and canard wing coupling are more conducive to improving the lift coefficient than the original J-10A, even if the maximum take-off weight of the whole aircraft exceeds the 20-ton mark, the ground clearance is equivalent to the A type at most, considering that the former's internal oil should be slightly increased, The figure of 8,000 kg is still an exciting achievement.

Close to the maneuverability and air superiority ability of the original A-type, with a large bomb load and corresponding multi-purpose design, such an "all-round" fighter similar to the F-16 really made Long Yun's eyes shine.

Standing in the tall hangar in the sun, communicating with his fellow Chinese comrades, he did feel that, similar to the situation in the real world, the overall thinking and concept of the Chinese Air Force moving towards a new era are undergoing some changes; In the overall context of the global Cold War and even the world war, the commanders and fighters of the PLA Air Force have their own unique views, and the military development ideas reflected through the J-10 "Raptor" have, in a sense, also departed from the long-term Soviet model, but are moving closer to the model of the US Air Force.

As a member of the Eastern countries, it seems a little deviant in terms of military construction ideas from the main military composition of the northern neighbors and the socialist camp.

However, unlike ordinary military fans in the real world, who have really experienced countless fierce battles in the sky in the two worlds, and participated in battles that determine the future and fate of parallel worlds and even the real world, Long Yun's understanding and understanding of war is very different from the past, and it is more profound than most people.

He felt from the bottom of his heart that in the current world war, the Eastern bloc of countries following the Soviet model did benefit a lot from it, and could strive for victory in a full-scale war with a relatively backward level of science and technology, but with the continuous development of military technology, perhaps in the near future, numerical superiority will no longer be the master of victory and defeat in the sky, and the disadvantages of maintaining a huge scale of single-purpose fighters will become more and more obvious. I am afraid that the multi-purpose of fighter units is also an inevitable trend.

Just like the situation in the real world, the transformation from a "defensive air force" to a "offensive and defensive air force" can indeed be seen and felt by Long Yun.

In the face of severe challenges, the Chinese Air Force is also thinking about whether it can learn from the equipment ideas of the US Air Force and use a large number of multi-role fighters with controllable costs and comprehensive performance to complete most of the combat missions under the realistic situation that the scale of equipment cannot reach the level of the Soviet Air Force at once.
