The V-280 Valor tiltrotor will become the main helicopter of the US Army. The V-280 won the tender, which also included the Defiant X helicopter, developed by Sikorsky and Boeing. The US will replace 2,000 Army UH-60 Black Hawk utility helicopters with one unified Bell V-280. The V-280 Valor tiltrotor was developed by Bell Helicopter and Lockheed Martin. The V-280 has an all-composite fuselage, superior flight performance and lower cost than the competition. The V-280 Valor does not have a removable rotary wing, which significantly reduces the weight of the machine, and there is no rotary engine - only the propeller rotor changes the position. By using dual motors with common drive shafts, both rotors can be powered by the same motor in the event of a mechanical failure. The tiltrotor crew consists of four people and can carry up to 14 paratroopers with heavy weapons. The tiltrotor has a cruising speed of 520 km/h, a service ceiling of 1800 meters and a combat range of up to 1480 kilometers.
