Qi Coleman developed before the United States helicopters, after the project costly defense project due to adjustments to be cut.
Liberation Army Daily reported on June 21 reported that Russia recently decided to invest one billion U.S. dollars developing a new generation of armed helicopters, will highlight the speed, stealth and other technical characteristics. As planned, all the best circumstances, Russia will launch the next generation in 5 years of armed helicopters. By then, the new generation of helicopters will be \Army newspaper editorial Aviation Institute invited Professor Zhang Dehu, insight into this hot issue.
body structure

advanced all-composite

recent years, the helicopter rotor technology, especially the rapid development of technology, largely depends on composite materials, nano technology. People on the composite materials in helicopter applications, called the second revolution in the helicopter, it shows a big role.
helicopter complex structure, more mobile components. Once the components of fatigue, it is easy to cause a variety of accidents. Light weight composite materials, fatigue strength, not a sudden break, impact resistance capacity than the metal strong, lightning is also not penetrate the blade, can greatly increase the safety of the helicopter.
20 century and 90 years, cooperation between Germany and France made the \United States, \At present, all-composite body testing machine has come out. Predictable, especially the advanced carbon fiber composite materials to be used in next-generation helicopters.
motor speed

more than 600 kilometers per hour

the Iraq war showed that the helicopter was shot down slow is one of the important reasons. Therefore, a new generation of high-speed flight characteristics of helicopters important technology, its cruising speed of at least 600 km / hour or more, a range of more than 1,000 km (two indicators are close to the fixed-wing aircraft).
Although helicopters can take off and land vertically, but the rotor limit, the flight speed is relatively slow. In recent years, researchers continue to find new ways in order to greatly improve the speed of the helicopter flight. For example, the United States and X2 coaxial helicopter rotor with propeller technology. This technology is the level of the helicopter fuselage center axis, respectively, vertical and horizontal installation of a rotating propeller system, the two propeller systems simultaneously, it will greatly improve the speed of the helicopter flight.
Currently,[link widoczny dla zalogowanych], the helicopter used by the world top speed of 250 km is generally within the range -350 km. And the Sikorsky Aircraft Corporation is developing a top speed of a helicopter X2 will be more than active duty for all helicopters, reaching 463 km / h,[link widoczny dla zalogowanych], is the U.S. \Russia is studying the three high-speed helicopter model - \Ducted through the use of dual-jet engine, the card -90 maximum speed of the helicopter will be more than 800 km / hour.
avionics system

highly integrated intelligent control

complex battlefield environment, put forward higher requirements for helicopter design. To this end, integrated, digital, intelligent avionics, will enable the helicopter flight control, communications, navigation, fire control, electronic warfare and other properties can be significantly improved, thus improving overall information warfare capability.
First, more advanced driving and control equipment. At present, generally more advanced helicopter equipped with computer, autopilot, Doppler navigation systems, night driving, laser range finder and other advanced driving and control equipment. Second, survival equipment, installation of electronic warfare. Generally equipped with modern helicopters, radar warning, laser warning and missile warning, and other electronic warfare equipment to survive. This multi-functional comprehensive integrated electronic survival equipment, so the alarm, identification, interference in one, active and passive jamming in one, radar and optoelectronic countermeasures in one, reaching a machine can effectively improve the battlefield helicopter viability. Third, the development of intelligent control into a new direction. The comprehensive use of technology on the basis of the maturity, the helicopter is equipped with integrated control, navigation, communications,[link widoczny dla zalogowanych], surveillance, alarm, automatic display system operations and failure can Zaijin Hang formed during the three-dimensional image reconnaissance, battle plans, reports, and self-correction and system for navigation.
stealth performance

full stealth design is unlikely

With the increasingly fierce confrontation between the modern battlefield, the helicopter's operational environment is more severe, increased stealth helicopter performance, has become an important direction for future development of the helicopter.
the United States, \The need for stealth helicopter in full swing, there has been a controversial topic. But \Therefore, a new generation of armed helicopters with full stealth design is unlikely.
However, armed helicopters for the pace of stealth performance will not stop, do not pay a large price for the local generation of stealth technology will be used helicopter gunships. Currently, some advanced helicopter gunships, such as \, infrared and other detection methods find, identify, track and attack, thus increasing battlefield survivability.
weapons configuration

more firepower against a more accurate

we can foresee a new generation of armed helicopters carrying more types of weapons, more advanced weapon systems, combat fire stronger, more precise targets.
ability to improve the helicopter firepower to mount the first to raise the amount of weapons. United States, \
U.S. AH-64D \for a total of 16 gold mount \three cannon, Beitan 750 hair. In contrast, a new generation of helicopters should have a strong integrated fire system, not only can hit multiple targets, and fire control are also high.
to meet future operational requirements, improve the precision helicopter strike capability is necessary. A new generation of helicopters will be a large number of advanced communication and sensor systems, to expand the battlefield vision to provide all-weather multi-target capability. Such as the U.S. Army Aviation's AH-64D \After the matter of the \Currently, the \other friendly aircraft, the precise coordination of the target launch attacks.
viability

application of crew escape system

modern war, with the increased ground fire, the helicopter is facing a growing threat. Iraq war in 2003, the U.S. Army 11th Aviation Regiment of the 32 helicopters, the first play to all \Technical staff recognized that improving the viability of the helicopter is the key to the development of a new generation of helicopters.
enhance the protective ability of helicopters to enhance its capacity the most direct means of survival. Such as the U.S. \After the bomb explosion ... ... These measures effectively improved helicopter anti-missile capability.
However, thick armor and then there is no guarantee the helicopter was not shot down. How to escape after hitting the helicopter will be the next problem to be solved.
helicopters and fixed-wing aircraft equipped with the biggest difference is that the rotor head. As the rotor structure and the reasons for low altitude, the helicopter when in distress, the driver can not like the fixed-wing aircraft pilots as an obstacle to the rotor head over too quickly pop machine outside the parachute to escape. Therefore, the main life-saving measures in the past helicopters are resistant to crash through the landing gear, fuselage, seats, shock-absorbing capacity of preservation of the crew crash-resistant.

Russian crew escape system successfully applied to solve this problem. Ejection life-saving measures are the most active measures, which allows the driver to a certain height and speed range missile from the helicopter. Ejection system mainly consists of the ejection control systems, landing systems, personal rescue packages. The main part of the system, the pilot seat. In normal flight, the pilots need to seat height can be adjusted. Distress, the helicopter cockpit doors automatically open at the top of the rotor and fuselage separation rocket system under the seat with the seat will be the pilot ejected. Then, the pilot and seat separation, fall parachute control and landing systems, to ensure that the pilot rate of decline no more than 7 m / sec. To have a personal life-saving bag inflatable rubber boat and a radio signal, after the pilot landed the position signal for the rescue services.
