Chapter 413： Once the black technology three

After arranging for the security personnel to start taking pictures of the v2 rocket, Bao Zixuan walked towards another box. Zhang Zhan and others have opened all the boxes, but they all know the boss's character. Therefore, I didn't peel off the oiled paper to see the contents, knowing that the boss wanted to be the first to watch it, so he couldn't steal Bao Zixuan's limelight.

There is also the fact that it is not clear how the Germans organize the information, and it will be more troublesome if it is messed up. The chances of being a disservice are very high, and I can only wait for Bao Zixuan to organize the information and take a quick photo and re-seal the box.

When he saw the blueprint, Bao Zixuan finally found the technical information he wanted most during his trip. This information is a dream for any aviation person. If Laomei did not get some of its drawings, it is estimated that it would take at least 20 years to develop F117, B2 and other aircraft. Yes, Bao Zixuan obtained the technical information of the German Holten 2-29 bomber.

The Holden, designated by Imperial Aviation as the Ho229, was a war-bombing prototype designed by brothers Lemar and Walter Holden and produced by Gotha during World War II.

It was the first flying wing aircraft to be propelled by jet engines. It also includes technology that can evade radar detection - this is the first fighter to have similar stealth technology, but the stealth performance of this aircraft is a coincidence brought about by the shape of the flying wing, not by design. The aircraft is loved by the German Air Force Grand Marshal Hermann Goering. This is the only aircraft that can meet his 3x1000 performance requirements, which is the so-called 1000kmh speed, carrying 1000kg bombs, and flying to destinations 1000km away. It is estimated to reach a speed of 1,024kmh and climb to an altitude of 15,000 meters.

The central pod is constructed of welded steel pipes, while the wings are constructed of carburized plywood. The air intake for the jet engine passes through the main spar of the wing, and the second spar connects with the elevator auxiliary wing. It is designed to have 7G load factor and 1.8x safety factor, so the ultimate load factor of the machine is 12.6G. Thickness-to-chord ratios for wings range from about 15% to 8% for wingtips.

The flight control system is composed of elevator auxiliary wings and spoilers. The flight control system of the aircraft includes two types of long-span spoilers and short-span spoilers. When used, the outer spoiler is activated. Such a system can make the Euler angle of the movable axis of the aircraft's flight control smoother and more elegant than a single spoiler system.

The Ho229 uses retractable three-point landing gear, with the nose landing gear of the first two prototypes being disassembled from the tail wheel system of the He177. And use the parachute to slow down when landing. The pilot is also equipped with an ejection seat. The engine originally wanted to use the BMW003 type, but due to the failure to complete the combat readiness in time, the Junkers Jumo004 was used as a substitute.

In later Hollywood movies, Captain America flies this plane. Bao Zixuan really saw the prototype of this plane with his own eyes, and there is only one left in the world at the National Air and Space Museum. As an aircraft engine designer, if you haven't been to the National Air and Space Museum, you won't be there. After all, all the classic aircraft in the world are displayed everywhere.

As the world's first stealth jet with a flying wing design, his performance and shape were absolutely alien at the time. And I have someone say that this aircraft is at least 100 years ahead of human technology, and the design concept is too advanced.

If the Americans did not get the ho229 aircraft, then there would be no future b2 ghost strategic bomber. The appearance of the two aircraft is too similar, it can be said that the b2 is an enlarged version of the ho229 is more suitable.

Now that the complete ho229 production technical information has been obtained, it will be relatively simple to develop other stealth aircraft in the future. In addition, he himself is engaged in the field of aero-engines, will it be too difficult to manufacture this aircraft. It can be said that being able to obtain the technical information of ho229 is a powerful thing for Bao Zixuan. The only worry is that it cannot be produced yet, even if it is imitation. This is a strategic bomber with stealth performance, and the British will never sit idly by when they know it.

Germany is limited by the lack of high-quality materials. Only wood, carburized plywood and ordinary steel can make the aircraft have 3x1000 performance, which is the so-called 1000kmh speed, carrying 1000kg bombs, and flying to destinations 1000km away. It is estimated to reach a speed of 1,024kmh and climb to an altitude of 15,000 meters.

Then, with a large amount of titanium alloy and rare earth resources, and how much steel is needed, the Heiyun Group can improve the performance of the aircraft to what state, just thinking about it makes people excited.

It is too late to appreciate the masterpieces of the Germans too much, and I can only wait until I return to Hong Kong to taste it slowly. Bao Zixuan quickly sorted out the information and arranged for someone to take pictures. Zhang Zhan and others were repacking the blueprints after taking the pictures, and the box was specially marked on it. After all, this is what Bao Zixuan valued the most so far. .

When Bao Zixuan called in another box with the technical drawings packaged in oil paper, he was stunned, and things were a little weird. It stands to reason that this thing should be a weapon that the Soviet Union is currently developing, how could it appear in the technical data left by Germany. Could it be that the Germans have already conceived and researched the finished product, which was captured by the Soviets after the war. It's just that the Soviet Union's industrial technology and production capacity were not good at that time, and it was not until the 1970s and 1980s that it was imitated. It is not impossible. After all, there are so many things stored in the minds of these German scientists that it is difficult for normal people to understand.

When the aircraft is flying close to the ground or the water surface, the airflow will flow backward and downward after passing through the wings. At this time, the ground or water surface will generate a reaction force. When it flies at a height equal to or less than 12 wingspan from the water surface, the entire The pressure difference between the top and bottom of the body increases, the lift will increase suddenly, and the drag will decrease, preventing 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 flying in the air, is called ground effect by scientists, and thus opens up the technology of ground effect flight.

The theoretical core of ground effect aircraft lies in the special phenomenon of ground effect: when an aircraft flies very close to the ground, its lift will suddenly become much larger than normal. As a general rule, to take advantage of the extra lift brought about by the ground effect, the aircraft cannot fly more than half the length of the wing.

The ground effect aircraft has fast speed, large carrying capacity, good stealth effect, and excellent seaworthiness. It can fly close to the ground or the sea, desert or swamp surface, and can use the blind spot of the radar to quickly approach the target silently and be 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 in the space above the water surface, its speed is 10 times or even more than that of ordinary ships, and more than 3 times that of hovercraft. The speed of ordinary ships is generally about 30 knots, the hovercraft is 40-140 knots, and the ground effect aircraft is as high as 100-320 knots. When flying, it is completely out of the water, and its speed is comparable to that of a helicopter.

After reading all the information, Bao Zixuan finally knew the truth of the matter. The Germans have long discovered the ground effect and have carried out research in this area. After World War II, these materials were taken away by the Soviets, and it is said that the Soviets had studied small ground effect aircraft long before the Caspian Sea monster But the strategic threat was not very big at that time, so it was not affected by the United States. Attention, it was not until the appearance of the Caspian Sea monster that this weapon appeared in the public eye for the first time.

This ground-effect aircraft designed by the Germans has not lost to the Caspian monster at all, and even slightly stronger in some performances. It seems that the Soviets still did not fully understand the technical data and drawings left by the Germans. You must not make such a mistake, and Bao Zixuan has already planned to develop a ground effect aircraft, and I believe 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 by a higher level; do these people really travel back like him, and the travel time is decades later than him; Star Technology. The things he designed were so bizarre that Bao Zixuan, who had always been well-informed, couldn't believe his eyes.

In the back box, I found a series of theoretical weapons such as flying saucers and sun cannons designed by German scientists. These technologies may not be produced even in another 100 years. At present, they can only be kept as souvenirs. The most important thing at the moment is Organize and categorize data.
