Chapter 2077: Self-respect

For any aircraft, the maximum take-off weight is greater than the maximum landing weight, because for take-off, as long as the power is enough, the flying distance is longer if it is not enough, but the landing is different. If you want to land, the landing gear needs to be It was too heavy to bear the impact, and when it came down, the leg broke.
Therefore, the landing weight is generally less than the takeoff weight. Anyway, under normal circumstances, the aircraft will burn fuel. If there is an accident, the takeoff will have to land. Then either the fuel will be discharged in the air or a few more laps.
For carrier-based aircraft, the problem of landing is even greater. The impact when it is landing is inherently great. The deck can withstand limited capacity. There are blocking cables when landing, and the weight that can be supported is also limited, so , A series of restrictions have led to the landing of carrier-based aircraft, and weight is an indicator to be considered.
This is actually an advantage of the MiG-29. This product is originally a medium-sized machine. The weight of the landing does not need to be considered. It must be within the acceptable range, but the current T-10K is different.
Why not use folding wings on the first aircraft? Because everyone has no idea, I think this thing has gained too much weight.
When it is changed to a carrier-based aircraft, the weight of all aspects will increase, the wings increase, the equipment increases, the body structure is strengthened, etc., the weight is whizzing upward!
Regarding the empty weight of this Su-27 modified carrier aircraft, which was later named Su 33, is a very interesting question. According to the later data, the empty weight of this aircraft is 18500kg, without the use of pylons. The empty weight is 18780kg. The latter argument is because the empty weight is dry. When lubricating oil and the like are added, the weight will increase by more than 200 kilograms. This weight is supposed to be not large, but if From the performance of Su 33, that is, when taking off weight, subtract the internal fuel, ammunition, etc., you can get another data. Its empty weight, the data obtained by the reverse calculation is 19750 kg, almost Nearly twenty tons!
This data is terrible, because the allowable landing weight of the Kuznetsov is only 22.4 tons. What does this mean? It doesn't matter during combat, but during normal training, this kind of aircraft is almost empty, flying without anything. If the aircraft is too heavy and it is too heavy when it comes back, you have to throw away the excess.
If you do this often, no one can stand it.
In fact, the Tomcat carrier-based aircraft also has this problem. It can mount six phoenixes to take off, but when landing, only four are allowed to be mounted, so it has to throw away two to land on the ship. However, people can mount it. Four landings are good enough. In a normal patrol, two are enough. Unless a war breaks out and anti-ship missiles fly over like a rain of arrows, they will luxuriantly mount six phoenixes.
Now, what about this Su-27 modified carrier-based aircraft? You can't hang anything at ordinary times!
This is its main problem.
The only advantage now is that with the help of Qin Guan, the weight of their radar has been reduced. The heavy inverted card antenna has been removed and replaced with a flat slot radar antenna. The weight is lighter by more than 200 kilograms, but, These alone are not enough. Their empty weight is still close to 20 tons. This is a major problem they face. How to convince the Navy to use this kind of aircraft instead of MiG-29?
Simonov's problem was pierced by Qin Guan's words, and he immediately knew that this Qin is always omnipotent, and he must have a way.
"Then you see, how to solve it?" Simonov asked.
"Where do you reduce it, you can't continue to punch." Qin Guan said with a smile. Of course, this is a joke. Now, after finishing this joke, he starts to get serious: "First of all, your electronic equipment is backward. If this fighter is fully purchased from our avionics, it can reduce its weight by another 300 kilograms."
The follow-up processing circuit of the radar has not been reinstalled, and there are also complicated heat dissipation pipes, etc. If you use the equipment of Han, these are the places where the weight can be reduced.
Completely reinstall our equipment. We are the equipment supplier. Qin Guan is serious, and Simonov is very embarrassed because he knows that there are many problems. After all, their planes are equipped with a bunch of Chinese equipment. , What is this all about.
If you asked me to provide advice, I naturally provided it. Back then, the F-11 was converted into F-11 B, and the empty weight was reduced by 600 kilograms. To a large extent, the avionics were reduced, Qin Guan thought secretly in his heart.
"Next, a large number of composite materials are used. Laying composite materials in many places can reduce the weight by another 300 kg to 500 kg."
Now, Han Guo has developed a series of composite materials. The appearance of such materials can greatly reduce the weight of the aircraft.
In fact, in the 1960s, composite materials for aviation have been developed. Now, some parts of the skin of fighter planes have begun to pave this kind of composite materials. For aircraft like F-117, almost all of the surface is covered. It is made of conforming materials, even for F-22 fighters, conforming materials have reached more than 20%.
For Xiong Guo, this aspect is still blank. For them, they would rather buy more titanium alloys than composite materials. After all, Xiong Guo has a lot of resources, especially titanium alloys, and they can even lavishly use the entire nuclear submarine. The shell is made of titanium alloy, but the research on composite materials is blank.
Now, if the outer surface of this aircraft is made of composite materials, it can continue to reduce its weight. In this way, Han will have to help, because they still have no technology.
Of course, Xiong Guo has a profound industrial heritage. If they want to study, they can definitely study it, but they don’t have time now!
The progress of this carrier-based aircraft cannot be delayed. Seeing that the aircraft carrier is almost ready to be built, they not only have to practice on the Nitka system, but also need to be on the ground with a real sword. Even, whoever gets on the ship first will be able to do so. It is conceivable to win the favor of the Navy.
"Finally, it is the flight control system. If the control of the flight control system is more precise, then this redundancy can be reduced, and it can be landed with heavier weight without danger." Qin Guan continued.
This maximum landing mass is limited in many ways. If the control system is more advanced and the impact force of landing can be reduced, then this weight can naturally be increased. In short, these require the cooperation of Han. As for Whether you use it in the end, that's your business. Qin Guan has already introduced this plan.
We are selfless to help.
