tilt rotor

[′tilt ‚rōd·ər]
(aerospace engineering)
An assembly of rapidly rotating blades on a vertical takeoff and landing aircraft, whose plane of rotation can be continuously varied from the horizontal to the vertical, permitting performance as helicopter blades or as propeller blades.

Fan propulsive efficiency being higher than that of conventional helicopter configuration, at cruise speed induced power is 20% less, while AVX also states that ducted fans are more efficient than tilt rotors. Combining greater speed and fuel efficiency, AVX estimates a 60% increase in productivity over conventional helicopters.
However, full production rates for the tilt rotor are still to be determined.
With the speed and range of a turboprop and the vertical takeoff and landing performance of a helicopter, the tilt rotor promises to infiltrate, exfiltrate and resupply SOF over long distances in a single night.
Original requirements for the special operations tilt rotor were shaped by the 1980 aborted mission to rescue U.S.
Though CV-22 payload and range benchmarks have changed during development, the tilt rotor advantages remain clear.
With the arrival of the tilt rotor, AFSOC intends to phase out its Paves from 2009 to 2014.
Testing at Edwards Air Force Base is to prove the mission electronics of the Special Operations tilt rotor in low-altitude penetrating flight profiles.
From a rolling takeoff overloaded to 60,500 pounds, the Air Force tilt rotor will self-deploy 2,700 nautical miles with a single refueling.
The tilt rotor covered flat terrain in both helicopter and airplane modes and at altitudes down to 100 feet.
In this much enlarged second edition, the author, a teacher and researcher in the field, seeks to provide a modern treatment of the aerodynamic principles of helicopters and other rotating-wing vertical lift aircraft, such as tilt rotors and autogiros.
It has the appearance of a conventional fixed wing aircraft, but with tilt rotors at the end of each wing, it can maneuver up or down and hover.
