Active torsion return means with a rotary actuator adjust lever stiffness for aircraft gearbox suspension.
Compliant carbon fiber spokes in the motor hub inhibit displacement and rotation, protecting the rotor from impact damage while reducing prop guard weight.
Segmented hinged shackles transmit loads to side panels, reducing mass and complexity of aircraft engine mounting systems.
A forward secondary structure uses two articulated cowls that pivot to provide large access openings while maintaining an aerodynamic fairing.
