Abstract

Physically-based researches on simulating helicopter motions have been achieved in the field of aeronautics, aerodynamics and others.These results, however, have not been applied in the computer graphics area, mainly due to their complex equations and heavy computations. In this paper, we propose a dynamics model of helicopter rotor blades, which would be easy to implement, and suitable for real-time simulations of helicopters in the computer graphics area. Helicopters fly by the forces due to the collisions between air and rotor blades. These forces can be interpreted as the impulsive forces between the fluid and the rigid body. Based on these impulsive forces, we propose an approximated dynamics model of rotor blades, and it enables us to simulate the helicopter motions using existing rigid body simulation methods. We compute forces due to the movement of rotor blades according to the Newton’s method, to achieve its real-time computations. Our prototype implementation shows real-time aerial navigation of helicopters, which are much similar to the realistic motions.
