Chapter 413

After arranging the security personnel to start shooting the drawings of V2 rocket, baozixuan went to 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 oil paper to see the contents. I knew that the boss wanted to watch first and couldn't steal the limelight of baozixuan.

Also, it is not clear how the Germans sort out the data. Once it is confused, it will be more troublesome. There is a great chance of helping. We can only wait for baozixuan to take photos and seal the box again after sorting out the data.

When he saw the drawings, baozixuan finally found the technical information he wanted most during his trip. This information is a dream for any airline. If the United States does not get some of its drawings, it is estimated that it will take at least 20 years to develop F117, B2 and other aircraft. Yes, baozixuan has obtained the technical data of German Holten 2-29 bomber.

Horton, named ho229 by imperial airlines, is a war bomb prototype designed by Lema and Walter Horton brothers and produced by Gotha during World War II.

It was the first flying wing aircraft propelled by a jet engine. It also includes technologies that can avoid radar detection - this is the first fighter with similar stealth technology, but the stealth performance of this aircraft is a coincidence brought by the flying wing shape and is not specially designed. The aircraft is loved by German Air Force Marshal Herman Goering. It is the only aircraft that can meet his 3x1000 performance requirements, that is, it can fly to a destination 1000km away at a speed of 1000kmh, carry 1000kg bombs. It is estimated that the speed can reach 1024kmh and climb to an altitude of 15000 meters.

The central pod is made of welded steel pipe, and the wing is made of carburized plywood. The air inlet of the jet engine passes through the main spar of the wing, and the second spar is connected with the elevator auxiliary wing. It is designed to have 7g load factor and 1.8x safety factor, so the limit load factor of the machine is 12.6g. The thickness to chord ratio of the wing ranges from about 15% to 8% at the tip.

The flight control system is composed of elevator auxiliary wing and spoiler. The flight control system of the aircraft includes two types: long-span spoiler and short-span spoiler. When in use, the outer spoiler is activated. Compared with the single spoiler system, this subsystem can make the Euler angle of the movable axis of the flight control of the aircraft smoother and more elegant.

Ho229 uses recyclable three-point landing gear, of which the nose landing gear of the first two prototypes is disassembled from the tail wheel system of he177. And use the parachute to slow down when landing. The pilot is also equipped with an ejection chair. The engine originally wanted to use BMW 003, but because it failed to complete the war preparation in time, Junke jumo004 was used as a substitute.

In later Hollywood films, the captain of the United States flew this plane. Baozixuan really saw the prototype of the plane with his own eyes. There is only one left in the world in the National Aeronautics and Astronautics Museum of the United States. As an aircraft engine designer, there is no one who has not been to the National Museum of Aeronautics and Astronautics. After all, all the classic aircraft in the world should be displayed everywhere.

As the world's first jet stealth aircraft with flying wing design, his performance and shape definitely wanted to be an alien at that time. And some people 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, there would be no B2 ghost strategic bomber. The two planes are so similar in appearance. It can be said that B2 is an enlarged version of ho229, which is more suitable.

Now that we have obtained the complete technical data of ho229 production, it will be relatively simple to develop other stealth aircraft in the future. In addition, he is engaged in the field of aeroengines. Will it be too difficult to manufacture this aircraft. It can be said that being able to get ho229 the technical data is a great addition to Bao Zixuan's strength. The only worry is that it can not be produced, even imitation. This is a strategic bomber with stealth performance. The British will never sit idly by when they know it.

Limited by the lack of high-quality materials, Germany can only use wood, carburized plywood and ordinary steel to make the aircraft have 3x1000 performance, which is the so-called destination that can fly to 1000km away at 1000kmh with 1000kg bomb. It is estimated that the speed can reach 1024kmh and climb to an altitude of 15000 meters.

It's exciting to think about how many black cloud group can improve the performance of the aircraft.

It's too late to appreciate the German masterpieces. I can only wait to return to Xiangjiang to taste them slowly. Baozixuan hurriedly sorted out the data and arranged for someone to take photos. Zhang Zhan and others are packing the drawings after taking photos, and the box is also marked with special marks. After all, this is what baozixuan values most so far.

When baozixuan called the technical drawings of oil paper packaging in another box, he was stunned. Things were a little strange. It is reasonable to say that this thing should be a weapon currently being developed by the Soviet Union. How could it appear in the technical data left by * * Germany. Could it be that the Germans had conceived and developed finished products, which were seized by the Soviets after the war. However, the Soviet Union's industrial technology and production capacity were not good at that time, and it was not impossible to copy them until the 1970s and 1980s. 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 flies close to the ground or water surface, the air flow will flow backward and downward after flowing through the wing. At this time, the ground or water surface will produce a reaction force. When it flies at a height equal to or less than 12 wingspan from the water surface, the upper and lower pressure difference of the whole body will increase, the lift will increase sharply, the resistance will decrease, and the aircraft wing will be prevented from falling. This physical phenomenon that can reduce the induced drag of aircraft and obtain a higher lift drag ratio than air flight is called ground effect by scientists, which opens up the ground effect flight technology.

The theoretical core of ground effect aircraft lies in the special phenomenon of ground effect: when the aircraft flies very close to the ground, its lift will suddenly become much larger than normal. According to the general law, to take advantage of the additional lift brought by ground effect, the flight height of the aircraft cannot exceed half of the length of the wing

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

Because the ground effect aircraft is only close to the water, but flying at 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, that of hovercraft is 40-140 knots, and that of 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, baozixuan finally knew the truth. The Germans have long discovered the ground effect and carried out research in this regard. 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 monster. However, at that time, the strategic threat was not great, so it was not valued by the United States. It was not until the Caspian monster appeared that this weapon appeared in public view for the first time.

The ground effect aircraft designed by the Germans has been completely equal to the Caspian monster, and even slightly better in some performance. It seems that the Soviets still did not fully understand the technical data and drawings left by the Germans. I can't make such a mistake, and baozixuan has planned to develop ground effect aircraft, and I believe it will be used soon.

The technical information behind is even more unrestrained, which is difficult to achieve in a short time.

However, after seeing the data, baozixuan's evaluation of German scientists was raised to a higher level; Are these people really the same as him, and the time of crossing is decades later than him; Or really got alien technology. The design is so incredible that baozixuan, who has always been well-informed, can't believe his eyes.

In the back box, we found some theoretical weapons such as flying saucers and solar cannons designed by German scientists. These technologies may not be produced in 100 years. At present, they can only be kept as a souvenir. At present, the most important thing is to sort out and classify the data.
