After arranging for the security guards to start shooting the drawings of the V2 rocket, Bao Zixuan walked towards another box. Zhang Zhan and the others had already opened all the boxes, but they all knew the boss's personality. Therefore, he didn't peel off the oil paper to see the content inside, knowing that the boss wanted to be the first to watch it, and he couldn't steal the limelight from Bao Zixuan.

There is also the fact that it is not clear how the Germans organized the information, and it will be even more troublesome if it is messed up. The chance of helping is very high, so you can only wait for Bao Zixuan to sort out the information and quickly take pictures and seal the box from the new.

When he saw the drawings, Bao Zixuan finally found the technical information he wanted most on this trip, which was a dream for any aviation person. If Lao Mei did not get some of its drawings, it is estimated that it will take at least 20 more years to develop F117, B2 and other aircraft, yes, Bao Zixuan got the technical information of the German Horten 2-29 bomber.

Houghton, named the Ho229 by Imperial Aviation, was a prototype of the war bombardment designed by the brothers Lema and Walter Houghton during World War II and produced by Gotha.

It was the first flying-wing to be propelled by a jet engine. It also includes technology that can evade radar detection - the first fighter to have similar stealth technology, but the stealth capability of this aircraft is a coincidence of the wing's appearance, not by design. The aircraft was loved by Luftwaffe Generalissimo Hermann Goering, and it was the only aircraft that could meet his 3x1000 performance needs, that is, it could fly to destinations up to 1000 km away at 1000 kmh and carrying 1000 kg of bombs. It is estimated to reach speeds of up to 1,024 kmh and climb to an altitude of 15,000 meters.

The central pod is made of welded steel tubes, while the wing section is made of carburized plywood. The jet engine air intake passes through the main spar of the wing, while the second spar connects to the elevator auxiliary wing. It is designed to have a 7G load factor and a safety factor of 1.8x, so the ultimate load factor of the machine is 12.6G. The thick chord ratio of the wing ranges from about 15%, and the wingtip is 8%.

The flight control system consists of elevator auxiliary wings and spoilers. The flight control system of the aircraft includes two types: a long-span spoiler and a short-span spoiler, which is used to activate the spoiler on the outside. This system makes the movable axis Euler angles of the flight controller smoother and more elegant compared to a single spoiler system.

The Ho229 uses a retrievable three-point landing gear, with the nose landing gear of the first two prototypes disassembled from the tail wheel system of the He177. And use a parachute to slow down when landing. The pilot is also equipped with a catapult chair. Originally, the engine was intended to use the BMW 003, but it was not ready in time, so the Junkers Jumo004 was used as a replacement.

In later Hollywood movies, Captain America flew this plane. Bao Zixuan really saw the prototype of this aircraft with his own eyes, and there is only one left in the world at the National Air and Space Museum in the United States. As an aircraft engine designer, there is no one who has not been to the National Air and Space Museum, after all, all the classic aircraft in the world are displayed everywhere.

As the world's first jet stealth aircraft with a flying wing design, his performance and styling were definitely like extraterrestrial at the time. And I said that this aircraft is at least 100 years ahead of human technology, and the design concept is too far ahead.

If the Americans had not gotten the HO229 aircraft, then it would not have been possible to have the B2 Phantom strategic bomber that would have topped the Daimyo later. The looks of the two aircraft are so similar that it can be said that the B2 is more suitable for the enlarged version of the HO229.

Now that we have obtained the complete technical data for the production of HO229, it will be relatively simple to develop other stealth aircraft in the future. In addition to the fact that he himself is engaged in the field of aero engines, will it be too difficult to build this aircraft. It can be said that being able to get the technical information of HO229 is a tiger for Bao Zixuan. The only concern is that it can't be produced yet, even if it is imitated. This is a strategic bomber with stealth performance, and the British will not sit idly by knowing it.

Germany was limited by the lack of high-quality materials, and only wood, carburized plywood and ordinary steel could give the aircraft 3x1000 performance, which means that it could fly to a destination 1000km away at 1000kmh and carry 1000kg of bombs. It is estimated to reach speeds of up to 1,024 kmh and climb to an altitude of 15,000 meters.

So with a large number of titanium alloy and rare earth resources, steel is even more or less how much Heiyun Group can improve the performance of the aircraft to what state, as long as you think about it, it is exciting.

I didn't have time to appreciate the masterpieces of the Germans too much, so I could only wait to return to Xiangjiang to taste them slowly. Bao Zixuan hurriedly sorted out the information and arranged for someone to take pictures, Zhang Zhan and others were repacking the drawings from the finished photos, and this box was also specially marked on it, after all, this is what Bao Zixuan values the most so far.

When Bao Zixuan called the technical drawings of the oil-paper packaging in another box, he was stunned, and things were a little unbelievable. It stands to reason that this thing should be a weapon currently being developed by the Soviet Union, how can it appear in the technical data left by Germany. Could it be that the Germans had already conceived and researched the finished product, which was captured by the Soviets after the war? It's just that the industrial technology and production capacity of the Soviet Union at that time were not good, and it was not copied until the seventies and eighties that it was copied, and it is not impossible to do so. After all, there are so many things stored in the minds of these German scientists that it is really difficult for normal people to understand.

When the aircraft flies close to the ground or water surface, the air flow will flow backwards and downwards after flowing through the wings, and then the ground or water surface will produce a reaction force, when it flies at an altitude equal to or less than 12 wingspans from the water surface, the upper and lower pressure difference of the whole body increases, the lift force will increase sharply, and the drag will decrease, blocking the aircraft wing from falling. This physical phenomenon, which can reduce the induced drag of the aircraft and at the same time obtain a higher lift-to-drag ratio than that of aerial flight, is called the ground effect by scientists, and thus opens up the ground effect flight technology.

The theoretical core of the ground effect aircraft lies in the special phenomenon of ground effect: when the aircraft flies particularly close to the ground, its lift will suddenly become much greater than under normal circumstances. As a general rule, in order to take advantage of the additional lift brought by ground effects, the flight altitude of the aircraft should not exceed half of the length of the wing

The ground effect aircraft has fast speed, large carrying capacity, good stealth effect, excellent seaworthiness, can fly close to the ground or sea surface, desert or swamp surface, can use the blind spot of radar, quietly and quickly approach the target, used for assault landing, can easily cross the shore anti-landing obstacles and mines.

Because the ground effect aircraft is only close to the water, but it flies at a low altitude above the water surface, its speed is 10 times or even more than 10 times that of ordinary ships, and more than 3 times that of hovercraft. The speed of ordinary ships is generally about 30 knots, hovercraft is 40-140 knots, and ground effect aircraft are as high as 100-320 knots. When flying, it is completely out of the water and has a speed comparable to that of a helicopter.

After reading all the information, Bao Zixuan finally knew the truth of the matter. The Germans had long discovered the ground effect and had studied it. After World War II, this information was taken away by the Soviets, and it is said that the Soviets worked on small ground-effect vehicles long before the Caspian Sea monster. It's just that the strategic threat was not very great at that time, so it was not taken seriously by the American side, and it was not until the appearance of the Caspian monster that this weapon appeared in the public eye for the first time.

This ground-effect aircraft designed by the Germans is not inferior to the Caspian Sea monster at all, and is even slightly stronger in some performance. It seems that the Soviets still did not fully understand the technical data and drawings left by the Germans back then. I must not make such a mistake, and Bao Zixuan has already planned to develop a ground-effect aircraft, and I believe that it will be used soon.

The technical information behind is even more imaginative, and it is difficult to achieve in a short period of time.

However, after seeing the information, Bao Zixuan's evaluation of German scientists was raised to a higher level; could it be that these people really traveled back like him, and the time traveled was decades later than him, or they really got alien technology. The design is so unbelievable that Bao Zixuan, who has always been well-informed, can't believe his eyes.

In the back box found a series of theoretical weapons such as flying saucers and solar cannons designed by German scientists, these technologies may not be able to be produced even if they are 100 years away, and can only be kept as a souvenir at present, and the most important thing at the moment is to sort out and classify the data.
