Chapter 73 Reduce Empty Weight
One pilot has three fighter jets available, which is indeed rare in modern war conditions.
Regarding pilots and fighter jets, unlike the simple and cheap fighter jets decades ago, the production costs and labor hours of modern fighter jets have increased rapidly, and the output cannot reach the level of me-109 and G-21. In contrast, although the training of pilots is difficult and the number is also limited, generally speaking, a fighter pilot is only assigned to an aircraft.
This is the case in normal times, what about the war?
Faced with a large-scale full-scale war, as various belligerent countries entered the wartime system and expanded their weapons production capacity in large quantities, the output of fighter jets will naturally be greatly improved, but the corresponding combat losses are also more terrible. Generally speaking, there will not be too many fighter jet stocks in war.
And on the other hand, as long as the logistics can keep up, a fighter can strike two or three times a day, but pilots will be very tired when they fight once or twice a day, so sometimes there are cases where several pilots share one aircraft.
Of course, the so-called pilot's attack ability is completely inapplicable to Victor Rezenov.
I don’t know if it is because of its top technology or because of its abundant physical fitness, as long as the air situation and enemy situation allow it, this guy wishes to fight in the sky all day; and when the fighter takes off and fights, it must replenish fuel, compressed gas and other consumption, and also do some necessary maintenance and ammunition loading. At this time, it often becomes a pilot waiting for the plane, which is naturally very unfavorable to fully exert the combat power of the "Caucasus Death".
In order to avoid this situation, the 237 Fighter Air Force has long allocated him two su-27s. Now it has increased the total number to three at once.
Stayed in the hangar for a while and confirmed the issue of the fighter's distribution with Commander Samsonov. Long Yun reluctantly said goodbye to the Red No. 17 Su-27s. He knew that the fighter would be towed to other hangars tomorrow to make room for the upcoming new su-27m.
After some communication with the regiment commander, it was confirmed that the new fighter would arrive soon, but now he still had only one White No. 20 Su-27s in his hand to use. Long Yun remembered the modification plan he had just proposed to Kirilenko - he originally wanted to modify the landline as soon as possible to take off the airplane and find an opportunity to fight with the "shark", but now there is only one fighter jet available in his hand. He was worried that he would dismantle the White No. 20 radar, EOS and fire control system at once. It would make him inorganic use in the following large-scale air combat.
But when thinking about it from another perspective, since "anti-radiation combat" is on the string, he does not plan to carry out a traditional air battle from BVR to fighting, Long Yun still patted the engineer on the shoulder:
"Let's go! Igor, let's study the plan now."
He made up his mind to modify the landline. Although it was already late at night, Long Yun, who did not want to delay the launch of the air combat for a moment, still did not rest. Instead, he went to the repair workshop with Igor Kirilianko, who was used to staying up late. He compared the simple Su-27 fighter manual and few maintenance technical materials to seriously discuss the equipment disassembly of the fighter.
He proposed a plan to "disassemble radar and other electronic equipment" about Long Yun. He did not know much about the actual situation of air combat, so Kirilenko did not question how he would carry out firepower control after dismantling it like this. Instead, he raised another question:
"Victor, if you want to pursue lightweight fighter jets to improve thrust-to-weight ratio and maneuverability, isn't this idea very similar to the previous 'p-42'? But I probably know some of the situation of that aircraft. If it needs to be modified, it is really a huge project volume. Our current level is not that level."
"Oh! That's for sure, hehe."
Hearing Kirilenko mention "p-42" again, Long Yun thought that his request was not that exaggerated. He smiled and waved his hand to the engineer in front of him.
When it comes to "p-42", it may not be as well known as many models of the Su-27 family. In fact, this is a special version of the Su-27 single-seat model that has been specially modified to compete for aviation flight records. Although it is a member of the huge Su-27 family, in order to achieve the goal of greatly reducing weight and increasing the thrust-weight ratio, the aircraft can do everything possible. Not only did it remove almost all electronic equipment, replace the cone shell of the head made of aluminum alloy, but it also made certain modifications to the appearance, including lowering the hanging tail, canceling the ventral fin and caudal spine, changing the main wing tip to streamline, and then scraping all spray paint. Even most of the pneumatic control rudder surfaces were directly locked, and a series of related control mechanisms were removed.
After such a lot of trouble, compared with the overall weight and thrust weight ratio of the Su-27s, the empty weight of the "P-42" suddenly dropped to an incredible thirteen tons, compared with the 16.8 tons of the Su-27s, which is almost four tons lighter. In combination with two improved al-31fs that sacrifice their life for thrust improvement, i.e., the r-32 engine, the thrust weight ratio is almost close to the rare 2.0 in the aircraft, so the performance is also very exaggerated. Since 1986, most aviation flight records have been recaptured from the US "Stripe Eagle".
Of course, although Long Yun yearns for his thirteen-ton weight center of weight loss for such an exaggerated weight loss behavior of "p-42", he knows very well that this approach is neither feasible nor can he apply it.
Not to mention other measures, it is unacceptable to scrape off all the spray paint on the fuselage. If the fighter removes the spray paint, there will be only the yellowed aluminum skin oxide layer, which looks really bright and eye-catching. If you go to the battlefield to fight air battles like this, aren’t you afraid that the enemy will not be able to see their position clearly?
Therefore, Long Yun's current plan is much more conservative than the "P-42" back then. According to his idea, he can reduce the air weight of the su-27s to over 15 tons by dismantling electronic equipment, ventral fin and wingtip missile slide rails, and then carry out combat patrols by bringing less fuel and relying more on air refueling.
In short, when facing a "shark", you can maintain a thrust-to-weight ratio of about 1.3!
After deciding on such an action plan, Long Yun was also looking through some technical information in front of the workbench. In fact, he had read these information more than once in the real world. Now he is just verifying and confirming to ensure that the basic structure of the Su-27 in the parallel world is the same as that in the real world, so his plan will be more guaranteed.
However, unlike Long Yun, who is confident, he intuitively felt that this matter was very risky when he heard his plan. Kirilianko asked with a skeptical look:
"I said, Victor, I know the weight loss plan of ‘p-42’, but can we really copy it like this?
After all, you have to think clearly that the abnormal model is just used to create a lot of climbing records. The onboard equipment is too disassembled. Not only is it impossible to perform combat missions at all, but it can't even fly out many minimum movements.
And, well… Although I am quite an amateur in this regard, if you dismantle it like this, you have to make changes in appearance. Do you have to rewrite all the flight control codes, or at least make some key changes? We can't do this here. If you hire a few experts from the Sukhoi Bureau from Moscow, it's almost the same, but you have to fly a fighter jet immediately, and you can't catch up at once?"
"Ah-yes, that's the problem."
Although he was aware of the series of changes he had to make, Long Yun nodded in agreement when he heard what Kirilenko said.
For a fighter with a fixed design, disassembly of onboard equipment and changing its aerodynamic appearance is not a joke at all, and it is not the same as a car changer making a fuss about cars.
First of all, in order to reduce the empty weight of the su-27s, dismantling a complete set of electronic equipment designed around the n001 radar can reduce the weight by about one ton. This has not yet been calculated as the weight loss benefit of replacing the radar cover with an aluminum alloy head cone. It seems to be a very cost-effective transaction. But the problem now is that dismantling the nose equipment weighing up to one ton will greatly change the center of gravity of the entire aircraft, and then there will be two additional effects - the good side is that the flight envelope of the su-27s can be expanded to a certain extent, and the upper limit of overload under certain altitude and speed conditions will be slightly increased; the bad side is that the fighter can enter a deeper degree of static instability, and the difficulty of handling will also increase exponentially.
In addition, Longyun also plans to make some changes to the aerodynamic shape of the su-27s, such as removing the two ventral fins at the back of the fuselage, and removing the antenna structure at the top of the vertical tail. In this way, coupled with the change in the center of gravity caused by the dismantling equipment, the heading stability of the su-27s will further deteriorate. To put it bluntly, it cannot fly too fast, otherwise the aircraft will "fly" and easily cause flight accidents.
Finally, due to his scrupulous air weight, Long Yun did not intend to retain the wingtip missile launch slide rails on the fighter, which would make the wings of the Su-27, which was already quite "soft", more likely to tremble, which would limit the flight range of the fighter.
In short, the so-called "there is no free lunch in the world", in order to greatly reduce weight without changing the overall structure of the aircraft, these measures can only be a temporary emergency measure.
However, Long Yun was not worried about the possible problems in this process. He had used simulation software beyond this era to verify it in the real world, and was basically familiar with how to control the backward shift of the center of gravity and a strange temper of the su-27.
With these conditions as a backing, Long Yun gave a confident answer to what Kirilianko said about "rewriting the flight control code":
“Igor, what you said makes sense.
