We have proposed a fluid repulsion computation method as an environment field force to simulate the object motion in fluid. It is capable of simulating fast, real-time and dynamic object motion in the fluid. This study verifies that the proposed method is more applicable for simulating the object motion in many situations in the fluid. We especially focus on a simple helicopter equipped with a circular wing. Numerical experiments show the followings; (1) the helicopter flight can be controlled by Artificial neural network, (2) fluid repulsion force can be figured out by uniformly dividing the wing area, (3) it is possible to compute the fluid repulsion force by the fewer number of dividing wing area, and (4) we find a better wing shape of da Vinci helicopter by analyzing da Vinci's helicopter in simulation and making a model of da Vinci's helicopter in the real world.
