US forces in the near futureThey are implementing a grand re-equipment program, as a result of which obsolete Black Hawk and Apache helicopters will be replaced by more advanced and high-speed flying machines. One of the most likely candidates for the place of the main U.S. combat helicopter is currently considered to be the Sikorsky-Boeing SB-1 Defiant, a prototype of which, in recent tests, reached a top speed of 383 km / h.
Keep in mind that being in service inThe UH-60 Black Hawk helicopter has a top speed of 358 km / h, with a cruising speed of 358 km / h. The new SB-1 Defiant helicopter provides accommodation for 12 passengers and four crew members.
US Department of Defense Project CompetitionUnder the Long Range Army Aviation Development Program (FLRAA), the main competitor to Sikorsky-Boeing SB-1 is the brainchild of Bell Helicopter, the Bell V-280 Valor tiltrotor (14 paratroopers and 2 crew members). The implementation of the FLRAA rearmament program will begin in 2022, last until 2030 and end with the adoption of new flying machines.
US Department of Defense Among Key Requirementsfuture helicopters indicates the need to ensure maximum flight range and high speed. Competitors to implement the requirements of the military department use the latest engineering and technological solutions.
Today's leader in contract racing helicopterSikorsky-Boeing SB-1 has two coaxial rotors and an additional pushing tail rotor, which will help developers realize plans to achieve a maximum flight speed of 530 km / h.
Competitor Bell V-280 Valor able to replacethe obsolete Bell V-22 Osprey model uses propellers located on the wings, capable of changing the working direction depending on the need for flight in a horizontal or vertical plane.
