A V-280 in flight with rotors tilted to hover configuration. The V-280 is designed for a cruising speed of 280 knots (320 mph; 520 km/h), hence the name V-280. It has a top speed of 300 knots (345 mph; 556 km/h), a range of 2,100 nautical miles (2,400 mi; 3,900 km), and an effective combat range of 500 to 800 nmi (580 to 920 mi; 930 to 1,480 km).
The Bell 30 was their first full-size helicopter (first flight December 29, 1942) and the Bell 47 became the first helicopter in the world rated by a civil aviation authority, becoming a civilian and military success. [3] Due to its burgeoning success, the helicopter division relocated as a separate unit to Hurst, Texas in 1951.
Development on the Future Long-Range Assault Aircraft (FLRAA) program and its winner, the Bell V-280 Valor, is continuing. [27] Reactions to the cancellation were mixed, noting that $9 billion had been spent over two decades on multiple cancelled programs, resulting in no replacement, and leaving the Army to rely on existing types to fill the role.
On 11 August 2014, the Army informed the Sikorsky-Boeing and Bell-Lockheed teams that they had chosen the SB-1 Defiant and V-280 Valor to continue with the JMR demonstration program. The aircraft designs show the Army is pursuing both coaxial and tilt-rotor designs, and preferring larger and established contractors over the smaller entries.

A modern nylon MA-1 bomber jacket. A flight jacket is a casual jacket that was originally created for pilots and eventually became part of popular culture and apparel. It has evolved into various styles and silhouettes, including the letterman jacket and the fashionable bomber jacket that is known today.
The first flight took place on 21 March 2019 at Sikorsky West Palm Beach site in Florida. [1] In the summer of 2019, flights were suspended to address a bearing issue with the main rotor. Flight testing resumed on 24 September 2019. [19] The aircraft reached a speed of 211 knots during level flight in October 2020. [20]
The Transcendental 1-G is the first tiltrotor aircraft to have flown and accomplished most of a helicopter to aircraft transition in flight (to within 10 degrees of true horizontal aircraft flight). Built in 1953, the experimental Bell XV-3 flew until 1966, proving the fundamental soundness of the tiltrotor concept and gathering data about ...
