Bell XV-3 – Fotos e Vídeo

Galeria de fotos de um Bell XV-3, O Sino XV-3 (Bell 200) foi uma aeronave tiltrotor desenvolvida pela Bell Helicopter para um programa de pesquisa conjunta entre a Força Aérea dos Estados Unidos e o Exército dos Estados Unidos, a fim de explorar tecnologias de convertiplane. O XV-3 apresentava um motor montado na fuselagem com eixos de transmissão que transferiam energia para conjuntos de rotores de duas pás montados nas pontas das asas. Os conjuntos de rotores de ponta de asa foram montados para inclinar 90 graus da vertical para a horizontal, o que foi projetado para permitir que o XV-3 decolasse e pousasse como um helicóptero, mas voasse a velocidades mais rápidas, semelhante a uma aeronave convencional de asa fixa.

The Bell XV-3 was a pioneering aircraft that demonstrated the feasibility of the tiltrotor concept, which combines the vertical take-off and landing capabilities of a helicopter with the speed and range of a fixed-wing plane. The Bell XV-3 was developed by Bell Helicopter under a joint research program between the United States Air Force and the United States Army in order to explore convertiplane technologies.
The Bell XV-3 had a single engine mounted in the fuselage that powered two wingtip rotors that could tilt 90 degrees from vertical to horizontal. The Bell XV-3 first flew on August 11, 1955, and performed 110 transitions from helicopter to airplane mode between December 1958 and July 1962. The Bell XV-3 program ended when the aircraft was severely damaged in a wind tunnel accident on May 20, 1966. The data and experience from the Bell XV-3 program were instrumental in the development of the Bell XV-15 and the V-22 Osprey, which are operational tiltrotor aircraft today.
