At the Bell Helicopter research center in Amarillo, the rotors for the new Bell V-280 Valor convertor were tested for the first time at full power. In comparison with the power plant of its predecessor, the V-22 Osprey, here the engines are moved beyond the rotary gondolas, which makes it possible in a critical situation to rotate the propellers from only one motor.
The V-280 convertor is the ideological heir of the V-22 model . The military traditionally asked for more speed, armor and payload, which was achieved by making almost all the assemblies of composite materials. The fuselage, wings, tail fins – everywhere use sandwich panels of large-celled carbon elements with integrated armor. It is 30% lighter than the previous version.
The future convertor will be able to fly at a cruising speed of 520 km / h, with a maximum load of 5,400 kg at a range of up to 1,480 km. Data on maximum performance is classified, but it is known that the US Army required aviation engineers to double the speed and power reserve in comparison with the old Osprey. Another property of the new convertoplan is the ability to hang in a helicopter at an altitude of 1800 m.
Valor will be able to transport 14 troops, plus two crew members. For rapid landing, two wide side doors are provided. Convertoplan received a triple dubbing control system, which takes into account and such data as the operational situation around, so as not to start the car inadvertently wrong. The first flight Valor can take place this fall.
