One design study concluded that if the mono tiltrotor could be technically realized, it would be half the size, one-third the weight, and nearly twice as fast as a helicopter. [30] In vertical flight, the mono tiltrotor uses controls very similar to a coaxial helicopter, such as the Kamov Ka-50.
In February 2023, pilots from the US Federal Aviation Administration (FAA) flew the AW609 tiltrotor, representing the first time the regulator's pilots had flown the type. The Leonardo company described the flight as a pre-TIA (type inspection authorization) activity, as it moves towards the final stage of the certification process. [56]
Bell-Boeing V-22 Osprey, the only crewed tiltrotor in production to date. A tiltrotor is a type of vertical takeoff and landing (VTOL) aircraft that convert from vertical to horizontal flight by rotating propellers or ducted fans from horizontal positions like conventional aircraft propellers to vertical like a helicopter's rotors.
In 2016, it was noted that the active blade control system developed for Project Zero, which removes the need for a swash plate and a separate vibration-damping system, was to undergo flight testing on an AgustaWestland AW139; separately, the flight control laws used by Project Zero shall be used for a future tiltrotor project by AgustaWestland.
The Bell V-280 Valor is a tiltrotor aircraft being developed by Bell Helicopter for the United States Army's Future Vertical Lift (FVL) program. [2] The aircraft was officially unveiled at the 2013 Army Aviation Association of America's (AAAA) Annual Professional Forum and Exposition in Fort Worth, Texas.
The first XV-15 prototype aircraft, N702NA, was transferred back to Bell for company development and demonstration use. On 20 August 1992, the aircraft crashed while being flown by a guest test pilot. He was lifting off for a final hover when a bolt slipped out of the collective control system on one pylon, causing that rotor to go to full pitch.
The squadron is a Marine Corps test and development unit. Its mission is to conduct operational testing and evaluation of Marine Corps fixed, tiltrotor, and rotary-wing aircraft. The unit was re-designated to VMX-1 (from VMX-22) on 13 May 2016. [88]
The Bell XV-3 (Bell 200) is an American tiltrotor aircraft developed by Bell Helicopter for a joint research program between the United States Air Force and the United States Army in order to explore convertiplane technologies. The XV-3 featured an engine mounted in the fuselage with driveshafts transferring power to two-bladed rotor assemblies ...
