It is reported that Russia recently decided to invest $ 1 billion developing a new generation helicopters, will highlight the high-speed, stealth and other technical characteristics. As planned, all the best circumstances, Russia will launch a new generation of five-year armed helicopters. By then, a new generation of helicopters will be “long” Chengsha Yang it? Newspaper editorial special military Aviation Institute Professor Zhang Dehu, this hot issue in-depth interpretation.
Body structure
Advanced all-composite
In recent years, the helicopter rotor technology, especially the rapid development of technology depends largely on composite materials, nano-technology. People on the composite materials in helicopter applications, called the second revolution in the helicopter, is indicative of the great. Moncler Clairy down jacket in shiny black
Helicopter complex structure, more mobile components. Once the components of fatigue, it is easy to lead to a variety of accidents. Composite materials, light weight, high fatigue strength, not a sudden rupture, anti-impact ability stronger than metal, lightning can not penetrate the blade, can greatly increase the safety of the helicopter.

The 1990s, cooperation between Germany and France made “Tiger” helicopter on the use of the new all-composite wing blade. United States, “Comanche” helicopter all-composite bearingless rotor system, fuselage structures using composite materials accounted for 90%. At present, all-composite body of the testing machine is now available. Predictable, advanced carbon fiber composite materials, especially the new generation will be widely used in the helicopter.

Iraq war shows that the helicopter was shot down flying slow one of the important reasons. Therefore, the high-speed flight is an important technical features of the new generation helicopters, its cruising speed of at least 600 km / h, a range of more than 1,000 km (two indicators are close to the fixed-wing aircraft).

Although helicopters can take off vertically, but because rotor constraints, the flight is relatively slow. In recent years, researchers continue to find new ways in order to substantially improve the helicopter’s flight speed. For example, the United States X2 helicopter using coaxial double rotor propeller technology. This technology is in the horizontal center axis of the helicopter fuselage were vertical and horizontal installation of a rotating propeller system, the two work simultaneously rotating the propeller, it will greatly improve the speed of the helicopter flight.

Currently, the helicopter used by the world, top speed is generally 250 km -350 km range. And the Sikorsky Aircraft Corporation is developing a top speed of X2 helicopter will exceed all active duty helicopter to reach 463 km / h, is the U.S. “Black Hawk” helicopter 2 times the speed. Russia is of three kinds of high-speed helicopter model – “Miri” Design Bureau of rice-X1 and the “Kamov” design bureau card cards 90 and -92. Ducted through the use of dual jet engines, helicopters -90 maximum card speed may be more than 800 km / hour. Moncler Ski down jacket in purple

Complex battlefield environment, the design of the helicopter higher demands. To this end, integrated, digital, intelligent avionics system would be a helicopter flight control, communications, navigation, fire control, electronic warfare and other properties can be significantly improved, and thus improve the overall information warfare capabilities.
