According to the Russian satellite news network reported on the 19th, the Russian agate company general manager and chief designer Georgy Antsev recently said that the Alekseyev Central Hydrofoil Design Bureau is building a sea with a weight of about 500 tons Ground effect aircraft. Chinese military experts believe that ground-effect aircraft have a series of advantages over existing ships and aircraft, which is very suitable for use in the vast water surface of the South China Sea, but many problems also limit the development of such aircraft.
According to the report, at the "Russian Marine Industry" forum, the Russian company has already demonstrated a ground-effect aircraft with a take-off weight of 60 tons. Antsev said: "The ground effect aircraft is widely used and can be used as a passenger aircraft. It can also perform the tasks of the Arctic region and defending the national border." Antsev said that the company should obtain a multi-functional ground effect aircraft from the Central Design Bureau. Can be customized according to the needs of different departments.
The so-called "ground effect" is the abbreviation of "ground effect", that is, the aircraft is flying at low altitude and during the take-off and landing, the ground produces an effect that reduces the wing induced resistance, increases the lift-to-drag ratio, and significantly increases the lift of the aircraft. . The ground effect aircraft using this effect usually flies at a height of 1-6 meters from the water surface, and the speed is close to the aircraft, which is 10 times that of the ordinary ship and more than 3 times that of the hovercraft; while the carrying capacity is aligned with the ship, the transportation cost is much lower than that. aircraft. In the military, the low-altitude ground effect aircraft is difficult to be discovered by using the radar blind zone of the other side, and can avoid the attack of the other side's air defense firepower; when used for assault landing, it can also fly over the ground or swamp like a hovercraft, and easily cross the shore. Landing obstacles and mines. The Alekseyev Central Design Bureau has successfully developed a number of large-scale ground-effect aircraft. The model number KM-6 is by far the largest ground-effect aircraft with a maximum take-off weight of 544 tons. NATO refers to this "weird thing" as the "Caspian monster."
A Chinese military expert believes that for China, the ground effect aircraft has a wide application space in the South China Sea. On the other hand, the ground effect aircraft also has a series of technical problems to be further solved. For example, when the ground-effect aircraft flies in the sea, the fuselage is most inclined to tilt. It cannot turn as much as the airplane. It must climb before it can turn. After correcting the route, it will drop to the ground effect height. This is equivalent to the plane's take-off and landing. . The accidents in the aircraft take-off and landing stage accounted for more than 65% of the total accidents.
