Bell V-280 Valor Next-Generation Tilt-Rotor Aircraft Prototype Has Just Made Its First Flight

8 Commenti

The Bell V-280 Valor prototype has successfully achieved first flight at the Bell Helicopter assembly facility in Amarillo, TX.

On Dec. 18, the first prototype of the V-280 Valor, registration N280BH, performed its first flight at Bell Helicopter Amarillo Assembly Center.

Interestingly, both the images and the footage released by Bell Helicopter have been doctored to hide some details of the Valor’s T64-GE-419 tilting gearbox design: unlike the V-22‘s engines that rotate along with the gearboxes, in the V-280, the gearbox is the only thing that rotates.

Anyway, the gearbox is clearly visible in the images we have published on Aug. 30.

The V-280 Valor is Bell’s submission for the U.S. Army’s Joint Multi-Role Technology Demonstrator (JMR-TD) phase, the technology demonstration precursor to Future Vertical Lift (FVL), a replacement for the service’s Sikorsky UH-60 Black Hawk and Boeing AH-64 Apache helicopters.

The V-280 will have a crew of 4 (including two pilots) and be capable of transporting up to 14 troops. Its cruising speed will be 280 knots (hence the designation V-280) and its top speed will be 300 kts. It’s designed for a range of 2,100 nautical miles and an effective combat range of 500 to 800 nmi although the Army’s requirements for the demonstrator call for hot and high hover performance (at 6,000 feet and 95 F), and the ability to self-deploy 2,100 nautical miles at a speed of at least 230 knots.

From this point of view it appears even more futuristic….

As reported yesterday, the first prototype of V-280 Valor, Bell’s candidate to the U.S. Army’s Joint Multi-Role Technology Demonstrator (JMR-TD), in the running to replace the service’s Sikorsky UH-60 Black Hawk and Boeing AH-64 Apache helicopters as part of the Future Vertical Lift (FVL) program, was spotted at Bell Helicopter Amarillo Assembly Center attached to an engine test stand in preparation for the engine tests required ahead of its first flight scheduled next month.

In this post you can see a photograph, submitted by a source who wishes to remain anonymous, that provides a side view of the V-280 prototype, registered N280BH.

Along with the retractable landing gear, a triple-redundant fly by wire control system, and a V-tail configuration, the main V-280 feature is the futuristic tilting gearbox design where the output shaft is connected to the drive system through a spiral bevel gearbox that transfers power to the fixed gearbox and proprotor gearbox, which rotates on two big spherical bearings driven by a conversion actuator mechanism. In this way, the gearbox is the only thing that rotates whereas the engines do not. Moreover, a driveshaft runs through the straight wing, allowing both prop rotors to be driven by a single engine in case of engine loss.
