Hybrid inverse/optimization design method for rigid coaxial rotor airfoils considering reverse flow

Aerospace Science and Technology, 2019
Abstract Double-ended airfoils with round leading and trailing edges outperform conventional round-nose and sharp trailing-edge airfoils when used for the inboard part of a rigid coaxial rotor operating in forward flight, as reverse flow can occupy 80% surface of the retreating blade. However, aerodynamic design optimization for this kind of airfoils

Numerical investigation on aerodynamic noise of rigid coaxial rotor in forward flight with lift-offset

International Journal of Aeroacoustics
A computational fluid dynamics (CFD) solver based on Reynolds-averaged Navier–Stokes (RANS) equations and high-efficiency trim model is used to simulate the unsteady aerodynamics of coaxial rotor. Farassat 1 A equations are adopted for predicting rotor far-field aerodynamic noise.

High-efficiency hybrid trim method for CFD simulation of rigid coaxial rotor

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2022
In order to solve the trim problem of computational fluid dynamics (CFD) simulation for rigid coaxial rotor, a hybrid trim model coupling CFD method and high-efficiency model (blade element theory) is established. In the trim process, the Jacobian matrix is solved by the high-efficiency model, while the CFD solver is only called for rotor performances
