Abstract
Aerodynamics simulation of a small airplane in acrobatic flight has been simulated using moving computational domain (MCD) method. At present, Digital Flight which is the method of flight test using computer is studied in the world. In our laboratory, the simulation of flow field around an airplane which moves turn flight has been performed as a first step of the challenge toward the realization of Digital Flight. As a next step, the purpose of this paper is to simulate a flow field around a freely-moving small airplane in acrobatic flight. Flow field around the small airplane in acrobatic flight was simulated and shown in detail in this paper.
