Design, development and flight qualification of a supercritical composite shaft drive line for tiltrotor main drive system

Project description

Twirling and tilting to lift and propel a new generation of civilian aircraft

Composite materials of high strength and stiffness are excellent candidates for aircraft drive shaft applications that transfer the torque from the engine to the rotor. However, damping in composites can be much greater than in most metals. In the "subcritical" speed range and at closer distances between components, this may not be an issue. In the supercritical regime of interest to applications involving longer distances as, for example, in helicopters and tilt rotors, it can lead to instabilities. The EU-funded STEADIEST project is developing two different architectures of a supercritical composite shaft drive line for the EU's first and fast tilt rotorcraft for the civilian sector.
