Coaxial rotor helicopters are a candidate for the next generation of rotorcraft due to their
ability to achieve high speeds without compromising hover performance. Coaxial rotors are …

In this work, the finite-state models of Morillo-Duffy and Fei (including the Adjoint Theorem)
are expanded to calculate the coupled inflow and rotor dynamics of a multi-rotor systems …

In the analysis of rotor forward-flight aerodynamics, a popular low-fidelity method is the
Blade Element Theory (BET), which requires the rotor geometry, blade motions obtained …

Low-and high-fidelity physics-based models for assessing the aerodynamic performance of
drone and eVTOL rotors under icing conditions are examined. The low fidelity model in this …

The effect of ground proximity on the some performance parameters of tandem rotors was
measured using a multifunctional test rig in this study. Trust, produced power and induced …
