RAH a 66 "Comanche" Xiamaguan, armed helicopters Inflatable boat for the development of all countries in the world are more cautious attitude. U.S. strategy is to upgrade the "Apache", while the procurement of new armed reconnaissance helicopter. Russia focused on the development of a card 52 "Alligator" and rice a 28 N "the night sky hunters." European "tigers" of the helicopter just to equip our troops, they can not develop the next generation of armed helicopters. However, from the United States last year announced the certification of the helicopter flight situation, despite the technical temporarily armed helicopters there will be no major changes, but all major countries in the development of new technologies and reserves, but did not stand still mean.
Iraq war shows that the helicopters flying low speed, low Inflatable boat height is an important reason was shot down. Therefore, the development of high-speed flight of armed helicopters (to reach its cruising speed 650 km / hour or more, the range of over 1,000 meters) to become the focus of Army Aviation equipment development.
To say to the fast pace of modern fighter aircraft have been more than three times the speed of sound, and the helicopter's speed is unsatisfactory. But the long term, the rotor of the helicopter restrictions beyond the low-flying subsonic speeds to the scope, in order to increase the speed of helicopters in recent years, attention to absorb the experience of fixed-wing aircraft, helicopters and light fixed-wing aircraft, known as "Compound helicopters." The so-called rotary-wing aircraft, the wings at the top with a long rotor blades, rotating blade surface in the promotion of Yiyi air, resulting in the aircraft took off at a rally of up to the rotor wing aircraft, like the vertical take off like a helicopter, In level flight, then use the principle of fixed-wing aircraft, namely the use of powered aircraft directly to forward flight. One of the most representative of the United States is the V-22 tilt-rotor helicopters and X-49 "at Eagle" helicopters, they are the traditional fixed-wing aircraft and helicopters combine the advantages of both the use of helicopters can take off and land vertically performance, Fixed-wing aircraft to play faster strengths. V-22 "Osprey" the prototype has reached the greatest level flight speed of 526 km / hour, much higher than conventional helicopters flying speed. However, due to technical reasons, this rotary-wing aircraft fate After bumpy, which in 2000 has crashed on the four, then once grounded for 18 months. At present, "Osprey" has adopted a variety of flight tests and to equip our troops. In the war in Iraq, "Osprey" outstanding performance, more than 2,000 hours Inflatable boat flying time, the task completion rate reached 68.1 percent. Bell and now the United States has also begun to study the follow-up of V: 44 large-scale tilt-rotor aircraft. In addition, Boeing is developing the X 1 50 A "duck-rotor aircraft" (WCR) has been a test flight, its speed of 741 km / hour or more, if successfully developed or achieve greater breakthroughs, the helicopter is expected to speed up to 600 ~ 700 1000 Metres, will be over 1,000 km range.
It can be said that with the rapid development of aviation technology to improve the speed and range of helicopters or guaranteed. If we can have and fixed-wing aircraft similar to the speed and range, plus the helicopter inherent flexible, minimum-altitude flight characteristics and strong, the future of armed helicopters will have a wide range of operational use.
