An Analysis of Harmonic Airloads Acting on Helicopter Rotor Blades. A helicopter rotor in forward flight is subjected to a complex system of loads, both aerodynamic and inertial in origin. A full-span free-wake method is coupled with an unsteady panel method to accurately predict the unsteady aerodynamics of helicopter rotor blades in hover and forward flight. The unsteady potential-based panel method is used to consider aerodynamics of finite thickness multi-bladed rotors, and the full-span free-wake method is applied to Cited by: 5.

Tiltrotor aerodynamic interaction, especially in the transition mode, is a necessary consideration for tiltrotor aerodynamics, and structural design and optimization. Previous studies have paid much attention to the helicopter mode. However, due to the substantial complexity of the problem, only a small amount of work on the transition mode has been done so far. In this paper, the rotor&ndash Author: Zhenlong Wu, Can Li, Yihua Cao.
