Simulation of Unsteady Aerdynamic Load for Rigid Coaxial Rotor in Forward Flight with Vortex Particle Method [PDF]

, 2017
Co-axial rotor systems are frequently used for high-speed helicopters. Nevertheless, issues related to rotor-head drag,\ud aerodynamic performance and vibration should also be considered. Simulating the unsteady aerodynamic loads for a rigid\ud coaxial rotor, including the aerodynamic interactions between rotors and rotor blades, is an essential part ...
