Airfoil-Section Rotor Blades

  • 1508 Accesses

Part of the Advances in Industrial Control book series (AIC)


The work done in the previous chapter is further extended to the design of a two-cell airfoil cross-section which is a more realistic model of the helicopter rotor blade. Optimum actuator placement, the effect of the current active twist concept on key characteristics such as blade loads, aeromechanical stability and trim controls is investigated. Aeroelastic analysis of the rotor blade is very important in the case of any refinement in the structural or aerodynamic model. Since the incorporation of piezoceramic changes the blade structural characteristics, it is important to ensure that the benefits gained due to the refinement should not be detrimental to the other aspects of the rotor such as performance, trim, and stability.
