K.Chapman - FLRAA Modernising the Army
The V-280 passes at high speed. This third-generation tiltrotor employs a remarkably different design to other aircraft in its class, such as the Osprey. It uses a V-tail, smaller wings and a sleeker, compound fuselage. It is also smaller than the V-22.
The V-280 transitions between flight modes. When the rotors are in airplane mode, the tiltrotor will be able to fly faster and manoeuvre like an aircraft. When employed in helicopter mode, the Valor will have the same characteristics - such as hovering - as a rotorcraft.
18 декабря 2017 г. на территории производственно-испытательного центра Amarillo Assembly Center компании Bell Helicopter состоялся первый самостоятельный полет летательного аппарата с поворотными роторами V-280 Valor. Новая машина создается в рамках американской военной программы Joint Multi Role Technology Demonstrator (JMR-TD) и рассматривается в качестве потенциальной замены ряда вертолетов армейской авиации.
V-280 N280BH (c/n 60105) in the hover at Amarillo on December 18, 2017. Bell has designed the V-280 with its T64 engines fixed in the horizontal plane, and a rotating (tilting) nacelle housing a fancy new drive system for the three-blade proprotors. On the V-22 Osprey, the engines are housed in the nacelles and rotate together.

The US FLRAA programme is one element of a wider effort to upgrade or replace much of its rotary capability
The SB>1 continues its flight test campaign. This shot provides a good view of the rear of the platform, showing its eight bladed 'pusher propeller' and twin-engine exhausts.
The FLRAA is the replacement for the UH-60 Black Hawk utility helicopter; likely competitors include those based on the Bell V-280 Valor tiltrotor (flying since 2017) and the Sikorsky Boeing SB-1 Defiant coaxial rotor compound helicopter.
The SB>1 Defiant is the largest platform produced by Sikorsky to employ its X2 technology.
The SB-1 Defiant is Boeing and Sikorsky's response to the US Army's requirement for a medium-lift utility helicopter under its Future Vertical Lift programme.
