The V-22 Osprey tilt-rotor is a US type tilt-rotor with vertical take-off and landing (VTOL) and short-range take-off and landing (STOL) capabilities. The V-22 tilt-rotor is similar in appearance to a fixed-wing aircraft, but two rotatable engines at the wingtip drive the two rotors. In the fixed-wing state, the V-22 looks like a two-wing wingtip with two An oversized propeller aircraft; in the helicopter state, it is a helicopter with two smaller rotors, so that it has the vertical lift capability of the helicopter, but has a fixed-wing propeller aircraft with high speed, long range and low fuel consumption. Advantages, the maximum flying speed of 509 kilometers, is the fastest flying helicopter in the world. And the United States is also studying Osprey's early warning aircraft and tanker models and vertical take-off and landing fighters. It is designed in accordance with the operational requirements of the four arms of the United States Air, Sea, Army and Marine Corps.

The V-22 tilt-rotor was jointly developed by the American Boeing Company and Bell Helicopter Company in the 1980s. It made its first flight on March 19, 1989. After a long period of testing, modification and verification. He entered the U.S. Air Force in service on November 16, 2006, and served in the United States Marine Corps in 2007. He went to Afghanistan for actual deployment in the same year. More than 200 V-22s have been produced. On February 18, 2011, James Amos, commander of the Marine Corps, stated that the MV-22 deployed by the United States Marine Corps to Afghanistan had flown more than 100,000 hours, and noted that the MV-22 had become the safest or most secure aircraft. The MV-22's accident rate per flight hour in the past ten years is only about half the average accident rate of the US Marine Corps flight fleet. The V-22 has become the rotorcraft with the lowest accident rate in the Marine Corps.

In addition to the V-22 Osprey tilt-rotor, Bell Helicopter is planning to develop the future tilt-rotor V-44. This type of rotorcraft, which is still on the map, is derived from the Osprey tilt rotorcraft. The rotorcraft has 4 wings, and each wing is equipped with a tiltable nacelle. The size of the rotorcraft is equivalent to that of an extended C-130 aircraft, which can hold 80 to 100 soldiers or 10 to 20 tons of cargo. Its payload is twice that of V-22 and its internal volume is eight times that of V-22. The V-44 rotorcraft can take off and land vertically. It does not require a runway or an airport. The range is between 1609 and 3218 kilometers, and the speed exceeds 483 kilometers per hour. In addition to being used as military and civilian transport aircraft, it can also be used for military purposes, such as missiles. Combat rotorcraft.
