Zusammenfassung:
This paper introduces a multi-dimensional "delta trim method" for computational fluid dynamics (CFD) simulations to compute the blade control settings that are essential for predicting rotor aerodynamics. The present trim method is based on the standard "delta trim method", but it achieves higher computational efficiency by using a combination of multi-level grid spatial and temporal resolutions. Two representative benchmark results are presented, including the AH-1/OLS rotor in forward flight and the HART-II rotor in descent flight. The numerical activities demonstrated the effectiveness of the new trim method. In addition, the novel method saves approximately 12% and 31% CPU time in the AH-1/OLS rotor and HART-II rotor cases, respectively, compared to the standard "delta trim method".
