A review of propeller stall flutter

Abstract Research on propeller performance has been reinvigorated by the development of new classes vehicles, ranging from electrically powered fixed-wing aircraft, to multi-rotor electrical Vertical Take-off/Landing (eVTOL) vehicles and tilt-rotor aircraft. These types aircraft utilise a range modern propellers, often with more advanced planforms features such as anhedral, operate in flight envelopes that are outwith traditional bands performance. The use materials (mostly composites), high geometrical sweeps variable angular velocities source unsteady aerodynamics, is coupled blade’s structural response. Data experimental investigations mostly historic, majority studies conducted before 1960, when aviation shifted rapidly towards jet propulsion. lack flutter boundary assessment. Modern propellers likely be pushed toward their boundaries, but database published to-date insufficient provide This review examines value available research status state-of-the-art numerical methods, order establish requirements for stall flutter.
