Web11 jan. 2024 · As the name suggests, rigid blades are firmly attached to the rotor hub (the "wheel" to which the blades are fixed at the top of the spinning rotor mast) by a swiveling connection called a feathering hinge (or pitch hinge). This allows them to "feather" (swivel as they rotate, which, as we'll discover in a moment, is how a helicopter steers). WebThey cannot flap or lead/lag, but they can be feathered. As advancements in helicopter aerodynamics and materials continue to improve, rigid rotor systems may become more common because the system is fundamentally easier to design and offers the best properties of both semirigid and fully articulated systems.
