Chapter 413 (2/2)
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.
