Compared to a propeller of an airplane or the rotor of a helicopter, the proprotor of a tiltrotor aircraft is a very ... of other optical measurement techniques (e.g. overall blade deformation, local ...

Italian investigators have determined that repeated contacts by an AgustaWestland AW609’s proprotor blades with the leading edge of its wing precipitated its in-flight break-up and fire.

Nonetheless, without a functioning and durable proprotor gearbox that does not have hard clutch disengagement or disintegrate - the V-22 cannot safely, reliably transition from vertical to ...

Shape memory alloy actuators integrated into the proprotor spar would enable the twist of the blade to be decreased from the 47.5¡ root-to-tip twist to improve hover efficiency, or increased for ...

The office's statement, released Friday, says that every Osprey's proprotor gearbox -- a key piece of machinery that transfers power from the engines to the aircraft's rotor blades -- needs to ...

During a Nov. 20 flight involving a CV-22B Osprey in New Mexico, the crew received warnings that the metal gears inside the aircraft's transmission, known as the proprotor gearbox, were in trouble.

The pinion gears are located inside the proprotor gearboxes on each wingtip. The gearboxes take in power from the Osprey’s engines and process it to turn the Osprey’s masts and rotor blades.
