Quasi-steady numerical calculation method for individual dynamic derivatives of aircraft

Year: 2025

Type: conference-paper

Abstract: In the existing CFD computation program, the non-inertial reference frame method is used to achieve quasi-steady numerical calculations for special motions such as quasi-steady climbing and level flight at constant altitudes. Using the SDM model as an example, the non-inertial frame method is applied to calculate damping dynamic derivatives. The results gained by using the non-inertial frame method for the calculation of dynamic derivatives match well with the data from the wind tunnel test, reference results, and other numerical results. The non-inertial frame method can reduce the computation time and enhance efficiency.
