The Wild Boar jet attack aircraft really made the leaders of the Eighth Route Army and the representatives of the allied forces overjoyed, with such an advanced attack aircraft, then the battlefield situation will be further changed, and the allied forces will soon win more victories.

At this time, Duan Yunpeng proposed a new model design plan to the leaders of the Eighth Route Army, which shocked the leaders this time.

Because this time Duan Yunpeng designed a fighter that can fly at supersonic speeds, the world's first supersonic fighter will be born in the Eighth Route Army Aircraft Factory?

If it is really successfully developed, it will change the mode of air combat again, and the future will be the era of supersound.

Therefore, the leaders of the Eighth Route Army are very aware of the changes brought about by this model, and they also know that the Allies will definitely like supersonic fighters very much, and when the time comes, they will buy hundreds or even thousands of them, isn't it going crazy to make money?

In this way, the victory of the Anti-Japanese War is just around the corner, and I don't even dare to imagine it.

The supersonic fighter submitted by Duan Yunpeng this time, nicknamed the Peregrine Falcon, is a fourteen-ton air superiority fighter, and of course it also has a certain ground strike capability.

However, it is mainly used for air supremacy, so its aerodynamic layout, similar to the later Falcon trainer or the Golden Eagle trainer of the stick, has a maximum flight speed of Mach 4, that is, about 1,700 kilometers per hour, which is nearly twice the speed of subsonic jet fighters.

So in air combat, the Peregrine fighter can easily defeat the opponent, whether it is a propeller fighter or a German-developed jet fighter.

You must know that the Germans are also very powerful, and developed a jet fighter during World War II, the most famous is the ME262, which was developed a few years ago, but it was not able to achieve mass production equipment earlier.

This is mainly because the German jet engine is not mature in technology, and it took many years to mass produce it, and its life is very short.

Another important reason was that the Germans gave priority to the development of the bombing version of the ME262 fighter, because the Germans hoped to use bombing to force the Allied offensive against the Germans to ease.

The design of the ME262 fighter is also the first generation, it looks similar to the original propeller fighter, except that two jet engines are hung under the wings, this is the Junkers Jumo004 engine, but the jet fighter came too late, and the advantage is not absolutely crushing, so the number is too small, the direction of the war has not changed.

The ME262 fighter shot down more than five hundred fighters and lost a hundred of them itself, so its superiority is still obvious.

However, compared to the Peregrine Falcon fighter designed by Duan Yunpeng this time, it is too far behind, this is a generation gap, so if there is a Peregrine Falcon fighter, then the next air battle between jet fighters will definitely be a victory for the Allies.

The peregrine fighter is equipped with an afterburner turbofan engine, which is an afterburner engine developed on the basis of the core engine of the non-afterburner turbofan engine of the wild boar attack aircraft, with a maximum military thrust of 48,000 N and an afterburner thrust of 8,000 N, which can be said to be quite large.

It is already equivalent to the level of the medium-thrust engine F404 that appeared thirty years later, of course, it is worse in terms of thrust-to-weight ratio, only 5.5 thrust-to-weight ratio, but this is enough, after all, there is no need for such advanced jet engines in this era.

The most important thing is that it has a long life, which can reach more than 500 hours, which is much stronger than those jet engines in Germany with a life of tens of hours.

Although the life of 500 hours is much worse than that of the military afterburner turbofan engine 20 years later, it is even better than the turbojet engine at that time.

After all, it is wartime, and the life of a fighter is usually not too long, like a propeller fighter, the life span is only a few dozen hours, and it will be shot down by the enemy, so the engine life at this time needs to be very long, because the pursuit of engine life is tantamount to a waste of money.

But for the Peregrine Fighter, it is the king of the sky, so its service life is certainly not comparable to those of backward propeller fighters, so it is also beneficial for its engine life to reach 500 hours.

After the first three hundred hours of use, it is necessary to remove it for major repairs, so that it can be used for another two hundred hours.

Usually a sortie counts three hours, so that it can take off and land a hundred sorties before changing the engine.

This is also very little pressure on logistics.

The firepower of the peregrine fighter is also very strong, because it is a fighter, so it is not equipped with a 30-mm Gatling cannon like a Boar attack aircraft, but a 20-mm four-barreled Gatling cannon.

This firepower is completely sufficient to fight planes, even if it is a bomber with thick skin and thick flesh, it is no problem at all.

Because the caliber is smaller, the weight is much lighter, and at the same time the number of shells carried is reduced to five hundred rounds, so that it can fly at supersonic speeds.

The Peregrine Fighter is not only fast and capable of flying at supersonic speeds, but also has a higher ceiling and a faster rate of climb, so that it can occupy an absolute advantage in air combat, and it can dive down at an altitude of 15,000 meters to attack the enemy's fleet.

So this time, the leaders of the Eighth Route Army saw Duan Yunpeng's design plan, and they were quite happy.

In the future, the Eighth Route Army will also be equipped with a small number of such supersonic fighters to maintain its own advantages, and it will not be long before the little devils are defeated.

The maximum take-off weight of the Peregrine Falcon fighter is 14 tons, and the aerodynamic layout makes it very flexible, and its maximum external weight reaches 3 tons, which can not only be used to hang three large auxiliary fuel tanks, so that its transfer range can reach 3,500 kilometers, but also can be hung with bombs and rockets when needed for ground attacks.

The design of the air intake is also a two-rib air intake design, similar to the Falcon trainer, but it is a single-seater, and the development of a two-seat type will be considered in the future.

In this way, it can also be on an aircraft carrier in the future and become a powerful carrier-based fighter, which must also be extremely attractive to the Allies.

Of course, the Allies don't have catapults now, so if this kind of carrier-based fighter wants to take off, it has to rely on the sliding deck.

But in general, the performance of the Peregrine Falcon fighter is very advanced, far beyond this era, the ME262 fighter is in front of it, it is really not worth mentioning, the two are not in the same class at all.

The maximum range of 3,500 kilometers must also be extremely attractive to the Allies, because then it can escort long-range bombers.

This time, the leaders of the Eighth Route Army quickly approved Duan Yunpeng's research and development plan.
