But even if these factors aside, does a heavy machine necessarily have an advantage over a light machine?

This problem, the average flying enthusiast often knows it, but does not know why, the hardcore fans of aviation competition are inevitably biased, in the two worlds have experienced countless air battles, for Long Yun, he has some personal opinions, just say it to Zhou Xiaodong at the moment.

According to the opinion of the first brother of "Chenlong", contrary to the intuition of many enthusiasts, the heavy machine that looks strong and powerful does not have much advantage over the light machine in terms of performance, because it is limited by the laws of physics.

As we all know, there are several types of most basic aerodynamic parameters for an aircraft that relies on aerodynamic forces rather than buoyancy to fly; Among them, there are many indicators that determine the maximum level flight speed and acceleration of the fighter, such as thrust-to-weight ratio, drag curve, etc., in this regard, the heavy aircraft has a definite advantage over the light aircraft, because the former is generally installed with two large thrust engines, it is not difficult to beat the single large thrust or double medium thrust light machine in the thrust-to-weight ratio, so generally speaking, the top speed of the twin-engine heavy aircraft is higher than that of the light aircraft of similar configurations, such as F-15 and F-16, Su-27 and MiG-29, the top speed of the former is higher than that of the latter, Sometimes the gap can be huge.

Of course, the maximum level flight speed at high altitude of a fighter aircraft should take into account the actual needs of different models, and it does not mean that light aircraft are necessarily inferior to heavy aircraft. But at least at the same level of technology. It is very difficult for a light machine to keep up with the speed of a heavy machine. This also determines that twin-engine heavy fighters generally have better interception performance.

In the competition of speed, heavy aircraft have a certain advantage over light aircraft, but when it comes to maneuverability, which is crucial in air combat, the situation becomes a little more delicate.

First of all, according to the theory of "energy maneuvering," which many people regard as the guideline, since the energy of fighters is very important in air combat, and because of the superiority of thrust-to-weight ratio and acceleration, it is easier for heavy aircraft to replenish energy than light aircraft.

Doesn't that mean. The former must be more mobile than the latter, and it is easier to win in grappling?

This point of view is obviously far from reality.

Purely considering the thrust-to-weight ratio, SEP, climb rate and other parameters, in terms of dynamics, the heavy aircraft of the same technical level is indeed superior to the light aircraft, but on the other hand, the parameter of "wing load", which determines the maneuverability of the fighter, is inherently inferior to the heavier aircraft with greater size and weight - to understand this, it is useful to consider a simplified situation, if the size of a certain type of fighter is proportionally enlarged by twice the original original. With the same structure, the lift area of the airframe will be quadrupled from the original. However, the weight will climb to eight times, and on the premise that there is no essential difference in aerodynamic configuration, this means that the "wing load" of the fighter will be doubled, and the maneuverability will inevitably be severely reduced.

Because of this, the strong heavy aircraft does not seem to need to pay the same attention to size as the slim light aircraft, and in order to reduce drag and weight, they have to think about a "wing load" that cannot be bypassed, and the result is that the heavy aircraft look relatively "flat", which is not just caused by the transverse twin engines.

If this principle is deviated, then the top speed of this heavy aircraft is mostly very good, but the maneuverability can only be regarded as average, as in the case of the MiG-25, F-4 and even the J-8.

Such a simple truth is not difficult to understand even without a little professional knowledge, and the topic of the two players turned to the fighter plane.

In order to ensure good maneuverability while increasing the size, some aerodynamic measures will inevitably be taken - such as the lightweight of the F-15 and the twisting of the leading edge of the main wing, the widened fuselage and variable sweep wing of the F-14, the large side strip and central lift body of the Su-27, in short, since it is a large aircraft, it must have some aerodynamic uniqueness, otherwise the maneuverability will inevitably not be able to compete with the contemporaneous light aircraft, This law did not change until the era of the fourth generation aircraft.

As an excellent aviation athlete, of course he understands what Long Yun said, but the so-called gossip, it is not easy to tell such a story as "Chenlong", obviously this guy has a very deep grasp of many models:

"Indeed, Brother Long, in the era of the fourth-generation aircraft, all countries are also 'eight immortals across the sea, each showing their magical powers', the Americans' F-22 'Raptor' followed the F-15 idea, the size of the body is small in the heavy aircraft, and the weight control zhì is also very good, and our 'Weilong', Soviet Russia's MiG-44 are not all the way.

However, when it comes to the so-called 'light aircraft', the 'ball electricity' can not make the Americans lightly, and the mobility of this thing in the fourth-generation aircraft cannot be compared with the 'Raptor', is it considered to have been counterattacked by a heavy aircraft? ”

"Hehe, of course!

Who let the 'fat electricity' be greedy and eat themselves. ”

In the aviation competition circle, every time you talk about the performance of fighters, it has probably become a bad taste to ridicule the F-35 "fat electricity", and the two laughed a few times, and Zhou Xiaodong changed to a very serious look:

"Hey, in that case, Brother Long, you must not value the maneuverability of the BM type, so what are our considerations?"

"Well, my idea is quite simple, heavy machines also have some benefits of heavy machines, the key depends on how we use them; Otherwise, if it is not the people who decide the victory, but the weapons, then what else is there to see in the aviation competition, the two sides will see whose grandfather Mao has more, and then the one with less money will directly eject and admit defeat. ”

Speaking of his own considerations, Long Yun of course proceeds from the overall strength of the "Chenlong", adding two twin-engine heavy Sukhoi in addition to the planned four J-10A, and his plan is not so much to use these two Su-27BM to participate in the chaotic group fight, but to prepare to form a more powerful BVR combat force in the "Chenlong", relying on the unique advantages of the Su-27 series of fighters to support the "Raptor" battle.

Su-27 and J-10, once the Chinese Air Force, naval aviation of the main aircraft, itself is also a very typical heavy aircraft and light aircraft, in the aviation competition in full swing in the background, the stock of a large number of "Diplodocus" and "Raptor", the comparison between the advantages and disadvantages of the two has long been well known.

Speaking of the advantages of the former, in Long Yun's view, it is probably a huge body based on the double-engine heavy-duty design, and a series of benefits that come with it:

Large internal oil range, large bomb load, better radar performance, and thrust-to-weight ratio advantage in actual combat conditions.

Since it was a casual conversation during dinner, and he was facing a good player in the circle, Long Yun didn't talk about Rory in these aspects, he focused on the significance of heavy aircraft to "Chenlong".

After all, the national selection competition is not a two-plane confrontation to decide the winner of the IFT regional qualifiers, there is not only one-on-one heads-up in the schedule, the real decision is the battle between the two fighter formations, according to the rules, even if you win in the air battle, it may not necessarily ensure victory, at least, there are many occasions for air-to-plane attacks in the competition environment, and J-10A is not a very suitable ground attack model.

“…… Therefore, if it is a formation operation, our tactical arrangements will definitely be further refined, and the more complex the battlefield situation and the more complicated the battle process, the greater the advantage of heavy aircraft.

Originally, I had this intention, and I also planned to lobby the funders to see if I could let the 'Chenlong' rent two heavy aircraft, otherwise I only relied on these 'Raptors', not to mention that the failure of the fighter or something would directly affect the competition, and if it really fought, the opponent would not necessarily fight with us happily, wouldn't it, if the situation fell into a stalemate, flying in the sky for a moment would give us more hope of winning, Lao Zhou, we can't just stare at the air battle. ”

"Indeed, if you consider the competition system,—— then our team will be decided, and you want the two of them?"

"Almost, another one, I'm also a little curious, what are the origins of those two Russian girls, who have so much money, and they actually come to play in aviation competitions, don't you think it's strange?"

Speaking of this, Long Yun squinted his eyes slightly, as if he was very curious about this matter, and the look on his face was a little strange, opposite Zhou Xiaodong, who swept away the contents of the plate and drank tea with a cup, was a little unclear So, he also thought that this "Chenlong" brother was looking forward to the prospects of the team, but he didn't know that Long Yun had already known some details with his superpowers, and these two girls who were less than twenty years old were obviously influenced by their father.

In addition to the cooperation and combat power between each other, he probably also spied a little bit of Anna and Natalia's family, Long Yun actually had the intention to recruit the two into the team early on, and there was a little bit of personal selfishness in this, but the reason for it, he himself was a little unclear why.

Déjà vu, a vague subconscious thought, but is it possible......

At noon that day, he talked in the restaurant, and he took the initiative to find Zhou Xiaodong to discuss team affairs, Long Yun had many considerations for doing this, "Chenlong" was formed not long ago, there were not many people in the team, and all of them were newcomers, and it was the first time that he recruited 800 people, and he felt that it was more appropriate to discuss with a veteran in the circle like the former vice captain of "Tianhe".

In addition, for this former opponent, he also has a little opportunity to investigate, not to say that he is wary, but to figure out some occasions outside the arena to deepen understanding, mobilize his worrying emotional intelligence to fully understand this competitive player, if he Long Yun is unable to participate because of some changes - thinking of the "organization" arrangement, it is simply certain, the young "Chenlong" needs a veteran with excellent skills and a mature mentality to lead the crowd.

Now it seems that this task can only be handed over to Zhou Xiaodong, even if this person's combat power cannot match his Long Yun, at least he still wins in terms of game experience.
