"Hopefully, the Germans will continue to have aircraft like the ME262 in this plane." Xu Jie cursed the Luftwaffe in the office with a wicked taste! According to Xu Jie's estimate, the technology of this plane is about 6 years ahead of history, and if this estimate is correct, then around 1938, Germany should have the ability to develop jet aircraft. And when it comes to jet fighters in history, I am afraid that the most well-known World War II jet aircraft is probably the ME262 Storm Bird. This aircraft was once touted by some on the 21st century network as the pinnacle of German World War II aviation technology, and as an example of surpassing Britain and the United States. But in Xu Jie's view, it is correct that the ME262 is called a cross-era aircraft and the pinnacle of German World War 2 aviation technology. But is it said to surpass the UK? Then let's wash and sleep.

Speaking of jets, then it is necessary to talk about engines, and in terms of propeller aircraft engines, Germany was finally thrown out of the street by the British. The BMW 801, which remained unchanged for 10,000 years, eventually lost to the British saber engine. And the liquid-cooled engine DB605 and JUMO213 series, which the Germans are proud of, are not as good as the British's Gryphon engine, not to mention the H-type 24-cylinder liquid-cooled engine used by the storm. IN TERMS OF JET ENGINES, THE MAXIMUM THRUST OF THE JUMO004 ENGINES USED BY THE GERMANS IS ONLY 900KG. And the British's Nien engine had already reached a thrust of 2270KG in ground tests before the end of the war. The Nien engine was the most performant and reliable engine of almost all engines of its time, and even more terrifying, almost all the aviation industry powers at that time. Britain, the United States, the Soviet Union, and France (Germany has already hung up, so it doesn't count) all four countries have used Nien engines or designed new engines based on them. This shows the power of the Nien engine.

Numbers on paper aside. JUMO004 biggest problem is stability, and the Germans did not have too high requirements for its use time when developing this engine. According to the standards of the Luftwaffe, it is good that this engine can reach a service life of 50 hours, but the actual result is that the average service life of the JUMO004 engine is difficult to reach even 20 hours. But what is certain is that JUMO004 engine is absolutely pitted! Responsible for the vast majority of mechanical accidents in ME262!

Although it is not known what kind of jet the Germans will produce in this plane, there will eventually be a jet that can fly. And Huaxia and the Entente must also make their own jets to deal with the storm birds in this plane. In terms of engines, there is the British ZÀI, which can be called the BT class. THEN EVEN ACCORDING TO HISTORY, THE 2270KG NYON ENGINE WOULD BE ENOUGH TO POWER THE FIRST GENERATION OF JETS. Although the potential of centrifugal engines is not as great as that of axial flow engines, in line with the principles of adequacy, stability, simplicity and convenience for mass production, the first generation of Chinese jet aircraft will still use centrifugal engines.

Like choosing a propeller aircraft, Xu Jie also likes to refer to famous aircraft in history. Although I don't understand aeronautical design, let alone area ratio or something. However, Xu Jie also knows that the most classic of the first generation of jet aircraft are the MiG-15 and F86. The performance is good, and the requirements for the engine are not high, so it is basically enough to change it with Nien. But one thing that Xu Jie is not satisfied with is that the nose air intake directly affects the installation of the radar. Although historically, both the MiG and the F86 have all-weather fighters equipped with radars. But considering the electronic level of the 50s in history, Xu Jie really didn't know that the fighter jets in service around 1940 were using nose air intakes. In the end, can it be installed with a better performance anti-aircraft radar?

The early jets were not without air intake on both sides, for example, the F2H Kraken had air intake on both sides. But in terms of flight performance, it is really inferior to the likes of F86. So Xu Jie fell into a dilemma of whether to fly or fight around the clock. At the same time, Xu Jie is also considering another question, that is, whether it is necessary for jet planes to be on board. Historically, it was unnecessary. But judging from the current situation, it is possible that Germany in this plane is stronger than Germany and Japan in history combined! And the technology is progressing fast.

So he hesitated again and again. Xu Jie's instructions to the following were to study two jet fighters at the same time. One is the imitation of the nose intake of the MiG-15, equipped with a single high-thrust engine. The Chinese version of the MiG-15 with a swept wing. The other is a modified version of the Banshee fighter that mimics the F2H's air intake method, with swept wings and two low-thrust engines. The former is to determine that there is a fighter with advanced enough performance, while the latter is to see if a breakthrough in performance can be achieved. At the same time, a modified version of the Banshee fighter will also produce a two-seater aircraft, which is equipped with an on-board radar and is designed for night combat. Jet aircraft are relatively fast, in the era when only cannons and rockets can be used to the air, it is easy to miss the target in the night battle, so it will be better to use the two-person pilot mode, anyway, it is a night battle, the probability of air combat is very small, and the flight performance is a little worse, it doesn't matter much.

As for airborne weapons? ALTHOUGH XU JIE WILL NOT PRESS A 37MM MACHINE GUN ON THE MIGER-15 LIKE MAOZI. HOWEVER, THE ORIGINAL 20MM CANNON OBVIOUSLY DID NOT FULLY MEET THE NEEDS. XU JIE MEANS A 30MM LONG-BARRELED MACHINE GUN SIMILAR TO THE MK101 PLUS TWO 20MM GUNS, THE LATTER MAY USE THE HISTORICAL 2 POST-WAR BORING GUNS. Thinking about the German MG213 rifled gun's rate of fire of up to 1,200 rounds per minute, Xu Jie was excited. THIS FIREPOWER DENSITY COMBINED WITH THE POWER OF THE 30MM GUN IS ENOUGH TO DEAL WITH ANY AIR TARGET.

In addition to fighter jets, jet bombers were also included in the R&D program. Historically, the Germans did come up with jet bomber designs like the AR234. But the real first-generation jet bomber in history also had to start with the TU16. From the point of view of the bombing effect, if you use ordinary bombs to attack, the accuracy of high-speed jet bombers is not as good as that of propeller aircraft. Because in the days when there were almost no fire control computers, it was necessary to use optical primitive sighting equipment for aiming. Surely the lower the speed, the better. Jets are too fast, which is why the AD1 Skyraider in the United States was used until the Vietnam War. The only advantage of the jet bomber is its penetration performance at high altitudes and high speeds. A jet bomber that breaks through from an altitude of almost 10,000 meters is an absolute nightmare for propeller aircraft.

In addition to bomber accuracy. Xu Jie is still not a newcomer to the jet engine of this era, you must know that even in the Korean War in history, the life of the VK1 engine made by the Russians by imitating the Nion engine was only 110 hours at the beginning, and although it was improved later, it was no more than 160 hours. A bomber can perform a mission much longer than a fighter, and a fighter may be able to perform 60 missions with the same engine life, while a bomber may only be able to perform 30 missions. And one high-thrust engine is enough for fighters, and at least two for bombers. The solution to this problem is not impossible, and it is enough to directly adopt a hybrid of propeller and jet engine. However, Xu Jie did not have much research on hybrid aircraft in history, so he simply left this problem to the R&D department to solve by himself.

In the end, Xu Jie decided to carry out research on jet bombers, even if they were not used in large quantities in the war, they could be used as a technical reserve, or small batch production, and then used as a penetration force to add guided weapons to strike at key targets. For example, capital ships, power plants, oil fields, or factories, etc.

Behind the jet aircraft development plan submitted by the General Armament Department, there is also a rocket weapons research program. This plan was added on an ad hoc basis. Among them, the development plan of air-launched rocket weapons is because the air force units participating in the war this time have responded that all kinds of machine guns are very difficult to deal with bomber units, and the power of the 20 mm machine guns is not enough, and the trajectory of the 30 mm short guns is not enough. AND THE WEIGHT OF THE 30MM CANNON IS REALLY UNSATISFACTORY. After all, no matter how good the armor protection is, no one wants to pass through the rain of bullets from large-caliber machine guns. Therefore, the Air Force asked the General Armament Department to develop an anti-aircraft weapon that could be used outside the range of the opponent. And it just so happened that the Air Force learned that the army was engaged in rocket artillery. So I wondered if I could change the army's rockets and throw them on planes to fight bombers. It's good to hit it, but it's okay to destroy the opponent's formation if you don't hit.

Xu Jie is supportive of this weapon, after all, in the European battlefield in history. The Germans used various rockets to attack British and American bombers, although the direct killing effect was limited. However, many bombers were killed because their formations were broken up. IN FACT, GERMAN'S ANTI-AIRCRAFT ROCKETS TOOK A DETOUR AT THE BEGINNING, THAT IS, THOSE SUPER-LARGE ROCKETS WITH A CALIBER OF 210MM OR EVEN LARGER. The weight of these rockets is enormous. Generally, a single-engine fighter can only be loaded with 1 round, and a twin-engine bomber is 2 rounds, although the ME410 twin-engine aircraft has a special modification of the use of wheeled rocket launchers (similar to rocket launch nests, a group of 6), but because of the sad way of placement, it can only shoot 2 rounds at a time. Such a small bomb load and launch speed make it difficult for an already tragic rocket to hit the target, even if the opponent is a slow and large target like a bomber!

HOWEVER, IN THE END, THE GERMANS FINALLY GOT THE HANG OF IT AND DESIGNED THE R4M ANTI-AIRCRAFT ROCKET WITH A CALIBER OF 50MM. This small rocket is mounted on a wooden pylon, and one ME262 can carry 24 rockets. In this way, at least the number of salvos can be guaranteed, and the number of passes can compensate for the lack of accuracy. In fact, in the 50s, when air-to-air missiles were not yet mature, rockets were still one of the main weapons used by fighters to intercept bombers, for example, the F89 Scorpion interceptor aircraft of the United States in history was the main one to fight bombers at high altitude with more than 100 rockets.

As a traverser, Xu Jie naturally knows that small-caliber rockets are the trump card against bombers in the future, and if they can be added with melee fuses, they can greatly increase the power of this weapon. Of course, it is also possible to increase the volume of the rocket appropriately in order to accommodate the electronic equipment that can accommodate the warhead. As for taking this rocket one step further and developing air-to-air missiles? This can only be said to be a technical reserve first, and then let's talk about it later.
