Design and development

The V-280 is reported to be designed for a cruising speed of 280 knots (320 mph; 520 km/h) (hence the name V-280),[40] a top speed of 300 knots (350 mph; 560 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). Expected maximum takeoff weight is around 30,000 pounds (14,000 kg). In one major difference from the earlier V-22 Osprey tiltrotor, the engines remain in place while the rotors and drive shafts tilt. A driveshaft runs through the straight wing, allowing both prop rotors to be driven by a single engine in the event of engine loss. The V-280 will have retractable landing gear, a triple-redundant fly by wire control system, and a V-tail configuration. The wings are made of a single section of carbon fiber reinforced polymer composite, reducing weight and production costs. The V-280 will have a crew of four and be capable of transporting up to 14 troops. Dual cargo hooks will give it a lift capacity to carry a 10,000 lb (4,500 kg) M777A2 Howitzer while flying at a speed of 150 knots (170 mph; 280 km/h). The fuselage is visually similar to that of the UH-60 Black Hawk medium lift helicopter. When landed, the wing is in excess of 7 ft (2.1 m) from the ground, allowing soldiers to egress easily out of two 6-foot (1.8 m) wide side doors and door gunners to have wide fields of fire. Although the initial design is a utility configuration, Bell is also working on an attack configuration

On 5 June 2013, Bell Helicopter announced that the V-280 Valor design had been selected by the US Army for the Joint Multi-Role (JMR) Technology Demonstrator (TD) phase. The JMR-TD phase is the technology demonstration precursor to Future Vertical Lift (FVL). The Army classified the offering as a Category I proposal, meaning it is a well-conceived, scientifically or technically sound proposal pertinent to program goals and objectives with applicability to Army mission needs, offered by a responsible contractor with the competent scientific and technical staff supporting resources required to achieve results.[4] JMR-TD contracts were expected to be awarded in September 2013, with flights scheduled for 2017

Whether different variants of the V-280 would fill utility and attack roles or a single airframe could interchange payloads for either mission, Bell is confident the Valor tiltrotor platform can fulfill both duties; the U.S. Marine Corps is interested in having one aircraft to replace utility and attack helicopters, but the Army, which leads the program, is not committed to the idea and wants distinct platforms for each mission. Bell and Lockheed claim an AV-280 variant can launch rockets, missiles, and even small unmanned aerial vehicles forward or aft with no rotor interference, even in forward flight and cruise modes with the rotors forward
