Embodiment Construction
[0050] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0051] The present invention proposes an aerodynamic simulation analysis method of "flapping-swiping-twisting" flapping-wing aircraft, including three-dimensional modeling, grid division, steady-state analysis, unsteady-state analysis, and post-processing. The specific steps are as follows: figure 1 shown, including:
[0052] Step 1: Establish a three-dimensional model of the aircraft wing, and determine the calculation domain of the flow field in combination with aerodynamic theory and related empirical formulas;
[0053] Step 2: Import the 3D model of the wing and computational domain into Ansys software, and perform mesh division and fluid analysis on it;
[0054] Step 3: Perform post-processing according to the simulation results to analyze the aerodynamic performance of the aircraft.
[0055] Further, the creation of the three-dimensional mode...
