Helicopter feathering
WebCollective feathering changes angle of incidence equally and in the same direction on all rotor blades simultaneously. This action changes AOA, which changes coefficient of lift (CL), and affects overall lift of the rotor system. Cyclic feathering changes angle of incidence differentially around the rotor system. WebIt starts with an introduction to helicopters, followed by a treatment of the technical background needed when studying them. Thereafter, dynamics, rotor systems, engines and transmission are explained in detail. The …

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). Web1 mei 2024 · Figure 1-2. Helicopters can have a single main rotor or a dual main rotor system. The rotor system found on helicopters can consist of a single main rotor or dual rotors. With most dual rotors, the rotors turn in opposite directions so the torque from one rotor is opposed by the torque of the other. This cancels the turning tendencies.
