When Duan Yunpeng and Zhang Xia stepped off the plane, they were greeted with the warmest applause.

The Allied representatives made another request for a test flight, and of course the leader of the Eighth Route Army still met their requirements, and it could be arranged tomorrow.

This time, the allies are very satisfied, such an advanced transport aircraft, when the time comes, a large number of allies will be equipped, and the good days of Xiao Ri and Xiao Dezi are estimated to be coming to an end.

It's just that the Allies still underestimate the Eighth Route Army's aircraft development capabilities, and just a few days after the successful first flight of the Giant Bird No. 1 transport plane, Duan Yunpeng began to design a new type of combat aircraft, which is a Wild Boar heavy attack aircraft with powerful ground attack capabilities.

This time, the wild boar attack aircraft designed by Duan Yunpeng refers to the A10 attack aircraft of the US military in the previous life, and this design is simple and crude, and it is very suitable for ground attack.

Although the later variable-swept wing supersonic fighter-bombers will be more powerful, they are still not as good as the A10 attack aircraft, so although it is ugly and does not look advanced, it is still in service for decades.

As for those fighter-bombers with swept wings, although they are very advanced, they have withdrawn from the stage of history early, so some things are not as advanced as possible, and it depends on whether they are suitable or not.

Of course, the variable swept wing is indeed good, but it is not suitable for use at this time, after all, it is too advanced, and it is very complicated to manufacture, not to mention maintenance and repair, in this era, I am afraid that there is no way to get it.

Moreover, the price of the weight of the variable sweep wing is too great, and the benefits in exchange for it are not very useful for the current ground strike, because there are no anti-aircraft missiles now, and there is no need for supersonic penetration.

Since the fifties, the variable swept wing layout has become popular, of course, as early as the end of World War II, the Germans have studied this aerodynamic layout, including the later flying wing layout, which the Germans also studied during World War II, and also built prototypes.

It's just that these are too advanced to save the fate of failure.

Therefore, later, the United States and the Soviet Union, on the basis of the Germans, developed variable-swept wing fighter-bombers, such as the F111 fighter and the MiG-23 fighter, and the British also developed the Tornado fighter, all of which were variable-swept wing layouts.

This time, Duan Yunpeng borrowed from the design of the A10 attack aircraft, equipped with two non-afterburner turbofan engines, which are simple and easy to use, and this will probably be the first turbofan engine in the world, so this wild hunting heavy attack aircraft has just begun to be designed, and Li Yunlong ran over.

This kind of heavy attack aircraft, if equipped, can be used to fight tanks like playing a game.

Because the tank is the king of land warfare, but it is very vulnerable to attack aircraft in the sky.

Although it is said that the tank has great firepower and defense, and is very flexible, it is not without its nemesis, and the fighter is a natural nemesis of the tank.

Because swooping down from the sky, striking at tanks, that is the most efficient.

In fact, the A10 attack aircraft is already too advanced equipment in this era, because in history, the A10 was an attack aircraft that began to be equipped in the seventies, and it faced a battlefield environment with strong anti-aircraft firepower, so its protection is very strong, not to mention the firepower.

Its Gatling cannon is so powerful that it can't withstand the top of any tank.

Of course, the A10 attack aircraft does not have a high strike accuracy against targets at a distance, but for targets at close range, it is accurate to hit a dozen and one accurate.

The A10 attack aircraft could carry six Maverick land-attack missiles, which had a range of less than fifty kilometers and were not considered the most advanced for their time.

However, the protection performance of the A10 attack aircraft is the strongest, because it is mainly used for close support, so considering the strike of ground anti-aircraft fire, it has a titanium alloy cockpit armor weighing more than 500 kilograms, which can resist the direct hit of 23-mm anti-aircraft artillery shells, and the damage of 57-mm anti-aircraft artillery shells can also be resisted.

For example, once an A10 attack aircraft was hit by a Sam individual air defense missile and broke half of its wing, but it was still able to fly back to the base, and returned to the battlefield after repairs.

So in the absence of anti-aircraft missiles, the A10 attack aircraft is really the best attack aircraft.

This time, the wild boar attack aircraft designed by Duan Yunpeng also opened the eyes of Li Yunlong and Yunxia.

Yun Xia almost wanted to laugh and said, "Yun Peng, the attack aircraft you designed, this is also too ugly, right?" ”

Duan Yunpeng said with a smile: "Don't look at it ugly, it can fight a tank, but there is no other plane that can compare, even a helicopter gunship." You see that its nose is equipped with a seven-barreled 30 mm Vulcan cannon, which can easily blow up any tank, because it is attacked from the top, which is easy to hit, in addition, it can also carry anti-tank rockets, various bombs, nine external attachment points, and the maximum bomb load can reach six tons, which can be said to be comparable to the Kunpeng No. 1 long-range bomber! ”

Li Yunlong said excitedly: "Oh my God, Ge Laozi, it can be compared with a bomber, this attack plane is good, just like a wild boar, with rough skin and thick meat, it can withstand beatings, and it has a strong attack power, and the tiger is afraid when he sees it." This attack aircraft is good! ”

Duan Yunpeng said with a smile: "No, our Wild Boar attack aircraft will also be equipped with the world's most advanced engines, these two engines are called turbofan engines, each with a thrust of more than five tons, adding up to more than ten tons, which can make our Wild Boar attack aircraft fly at a speed of 1,000 kilometers per hour, and the maximum take-off weight reaches 2.5 tons." So its Vulcan cannon can carry a thousand rounds of 30-millimeter shells, and it can also carry six tons of bombs. ”

Without attaching ammunition and three auxiliary fuel tanks, the range of the Boar attack aircraft reached 3,600 kilometers, which is quite high.

Of course, its drinking speed is indeed very fast, because the fuel in the plane is more than three tons, plus the three tons of external fuel, it is almost nearly seven tons.

So in the future, the Eighth Route Army will not have many equipment, after all, this thing is an oil tiger, so it is planned to equip more than 20 planes.

But it can be sold to the Allies, because the Allies need this advanced attack aircraft very much, and they are not afraid of running out of gas.

Therefore, the wild boar attack aircraft designed by Duan Yunpeng this time really made Li Yunlong excited, and he was still looking forward to equipping it as soon as possible, so that he could have more powerful air fire support.

When the time comes, he will also take the initiative to attack and beat the little devils and blow up more little devil tanks.

Of course, the battleships used by the Boar attack aircraft to bomb the devils are also very good.
