In the following month, Xu Jie not only inquired about the progress of the research and development of guided weapons and related carrier aircraft, but also specifically inquired about the progress of the research and development of several key types of fighters of the Air Force. Among them, the most important ones are the future main fighters of the Air Force, the Shicha Falcon single-engine aircraft, and the Seagull fighters, which the Navy plans to equip. Both aircraft are almost entirely based on historical American aircraft, with the Cascha Falcon equivalent to a modified version of the P51 fighter and the Seagull being a copy of the Corsair fighter.

"It's not easy, I finally moved the oil radiator on the belly of the P51 to the sides of the wing." Looking at the fighter in front of him that uses laminar flow wings and looks quite like P51, Xu Jie couldn't help but burst into tears! The P51B is definitely the most classic aircraft in World War II, as early as 1943, when it first came out, it had a top speed of more than 700 kilometers per hour, a climb of more than 4,000 feet per minute, and good hovering performance at high speeds, plus the high-speed cruise gain provided by laminar flow wings. This aircraft reached the peak of combat effectiveness and range of aircraft of the same period! Whether it's the stout P47, the compact BF109, or the Spitfire, which claims to be excellent for vertical and horizontal maneuverability, or the F190, which once had a brilliant record in 1942. The comprehensive performance is much worse than that of the P51B, so much so that by the end of the war, the Axis powers did not have a comprehensive performance comparable to the existence of the P51B!

However, this aircraft also has a lot of regrets, not to mention the fragile damage resistance of the liquid-cooled engine, it is a liquid-cooled aircraft once the engine is hit will crash quickly, there is no way not to crash, but the coolant is gone. What made Xu Jie haunted the most was the huge oil radiator in the lower part of the belly of the flat 51B machine. Radiators are usually installed in the nose, belly or wing roots. For example, some models of Typhoon fighters have a huge radiator in the lower part of the engine. So much so that the Typhoon fighter equipped with an H-type 24-cylinder liquid-cooled engine has huge frontal wind resistance. Some aircraft are equipped at wing roots. This is the case with the Corsair fighter for example, and there are also aircraft that are equipped in the lower wing of the wing, such as some models of the BF109.

If the P51B is not a good arrangement. The answer is yes, there are definitely benefits, cold air enters through the radiator port and becomes hot air and then sprays out from the rear. In this case, it will give the fighter an additional thrust, and in addition to the P51B, the BF109 and Spitfire also have this booster effect. But the P51B works best, the BF109 is second, and the Spitfire is the second. This layout is the greatest help for air combat, but the problem is that fighters need not only air combat, but also ground attacks. In some cases, it is necessary to mount a fuel tank. The P51B's huge radiator at the bottom of the belly prevents it from having the most theoretically load-bearing belly hardpoint. So the maximum hardpoint weight capacity of the P51 fighter is only 1000 pounds. And generally around 500 pounds. It is far less flexible in terms of loading than other aircraft with belly hardpoints.

For example, some models of the BF109 can hang a 500kg or 250kg bomb on the belly, and then hang two 300L mailboxes on the wings. The P51 fighter was not compatible with bombs and mailboxes of such a weight, as he had only two heavy pylons. You should know that the P51 can be larger than the BF109, so in order to increase the flexibility of the load, Xu Jie strongly recommends changing the position of the radiator in the belly. It's certainly not a good idea to put it in the nose, and the liquid-cooled engine is all about reducing the frontal area of the front, and you add a radiator to completely cancel out this advantage. So in the end the radiator was put in the lower part of the wing.

Another problem that made Xu Jie linger was the firepower of the P51B, which only had 4 machine guns, but the P51D had increased to 6. But compared with the 4 guns, 2 guns or 2 guns and 2 guns of the later F190, this firepower is too sad and urgent. And considering that the air combat in this plane needs to take into account the problem of interception of German strategic bombers, the firepower of 4 machine guns is really too sad. So Xu Jie decided to upgrade the firepower, but the price of the upgrade was to increase the weight. In particular, the weapons arranged in the wings will have a greater impact on horizontal maneuvering. And Xu Jie, as a traverser, came up with three firepower upgrade plans. …

The first option was to learn from the British Spitfire's firepower arrangement, with a 20mm cannon and an M2 machine gun in each wing. This layout is the most modest. The second option is to learn the BF109, install a 20mm cannon or a 30mm short-barreled gun on the engine bottom bracket, and then a 20mm gun on the wing side. The third way is to learn the layout of the F190, with two M2 machine guns mounted on the upper part of the engine, and then a 20mm cannon on each wing. In terms of effectiveness, the latter two have the best shooting effect, but there is a problem that neither Britain nor the United States has ever made such a layout in history. DB605 can press a cannon on the central axis, who knows if Morin can change it like this? So in the end, the designers chose the more conservative first option for the time being. If the subsequent engine can be changed, let's talk about it.

As a result, the designer accepted Xu Jie's two suggestions. It was found that the current performance of this aircraft is a little better than the original design, on the one hand, because of the reduced effect of the radiator thrust arranged at the wings. On the other hand, the weight of armaments has increased. The result naturally attracted objections from some designers. However, under Xu Jie's insistence and the fact that it can be used, this heterotopic plane P51 finally stumbled to complete the drawing and wind tunnel testing. Of course, from the design level, this aircraft is at most the level of the P51B. Like the bubble cockpit of the P51D and the super weight reduction of the P51H, there is no such thing.

The fighter of the land-based aviation has been chosen, and the next one is the carrier-based aircraft, originally Xu Jie thought that he had interfered with the design bureau to make a Chinese version of the P51 and caused enough things, who knows, the land-based aircraft is simply not a problem compared to the sea base! There was even such an incident, Yang Yonglin took a sea-based aircraft bidding document and specifically found Xu Jie and asked: "You are engaged in an attack aircraft, right?" This plane is not much lighter than our torpedo planes and bombers. At that time, Xu Jie choked enough.

In the face of the Minister of the Navy, whose anger value skyrocketed, Xu Jie was still very calm, and then decisively launched the necessary flicker skills of the traverser and began to fool Yang Yonglin! "First of all. Air-cooled engines are recommended for sea-based aviation, and air-cooled engines have a large frontal area, so in order to achieve the same performance, it is necessary to increase horsepower. And to increase horsepower you need to increase the weight of the engine, and that's right. Secondly. As a carrier-based aircraft, it is necessary to ensure the strength of the landing gear and the performance at low and medium altitudes, in order to achieve these two points, the weight of the aircraft is definitely increased, so the inverted gull design is adopted. This layout also allows the nose to be raised higher from the deck, allowing the use of larger propellers. Get the most out of your engine. Third, you are determined to ensure the range of the aircraft. It is required that the internal oil range reach more than 800 nautical miles in the state of air combat. This requires at least about 1200 liters of internal oil. You tell me, that's all there is to it. Can the weight of this aircraft be lower? Xu Jie asked rhetorically. Then feeling that the blow to the other party was not hard enough, Xu Jie continued to add: "If you want super high performance, but you don't want to pay the price, how can there be such a good thing in the world?" Deng Shi pushed the menacing Yang Yonglin back.

"No matter what, let my favorite pirate show up! Otherwise, this crossing would be too much of a failure. Watching Yang Yonglin leave the office angrily, Xu Jie muttered to himself proudly. However, Yang Yonglin is right, the pirate fighter is indeed a little too heavy, the historical pirate fighter has an empty weight of more than 9,000 pounds, and the normal take-off weight is more than 12,000 pounds. And the maximum take-off weight has reached more than 16,000 pounds! However, it turns out that the weight is really worth the price. At least Xu Jie believes that the Corsair is almost the most applicable aircraft in World War 2. The Corsair 4, which uses high-standard oil, can suppress almost all Axis fighters, like the P51B. It doesn't matter if you're a BF109K or an F190D9. (Of course, if you fly to an altitude of more than 10,000 meters, you can't fight with TA152.) As for the Japanese planes, it was easier to fight. …

And such a large weight and reinforced structure also give the Corsair fighter a good overload and strong payload capacity, (the specific data is mentioned above, so I won't say much.) If you count the theoretical load, there is only the F190F and the Corsair have a fight, but the former is done at the expense of the internal oil, and the internal oil of the F190F is only 500kg! The short range is terrible. The Corsair, on the other hand, relies on 1400L of internal fuel to have a range of 1000 nautical miles when cruising at low speed at 185 knots in an air combat state, and the aircraft has good low-altitude performance. It can be used as a dive bomber. So a pirate can be used as a bomber by hanging a bomb, and a fighter can be used as a fighter by throwing a bomb! As for whether it is possible to hang torpedoes. This question is easy to answer, the pirates in World War 2 can't hang. But the pirates after the 2 World War II were okay, the American AU1 once participated in the Korean War, and this aircraft was called F4U7 by the French, which itself was a derivative of F4U5.

The F4U7 takes the Corsair's arsenal to a new level, with a maximum take-off weight of 19,000 pounds, a maximum weapon load of 2,000 pound bombs, 10 rounds of 260 pound bombs, and the ability to hang a 150-gallon tank! And the most commendable thing is that this product has three rehanging points. All can be mounted up to 2000 pounds! That is, three torpedoes can be placed! Although only in terms of bomb load and the effect of ground attack, the F4U7 is inferior to the AD1, but its air combat performance is still better than the AD1 thanks to the fighter base. So the versatility of the Pirate series is quite strong.
