Abstract
Currently, manned drones, also known as flying cars, are attracting attention, but due to legal restrictions and fear of accidents, it is difficult to fly them. We therefore present a numerical simulation of the sudden stop of the rotor of an octrotor flying car. In this paper, we consider the interaction between fluid and rigid-body in a 6-degrees of freedom flight simulation of a flying car. For the purpose, the attitude of the aircraft is determined based on the force generated from the flow field around the aircraft due to the rotation of the rotor. The motion of the aircraft is obtained from the equations of motion of translation and rotation, and Newton's equation of motion and Euler's equation of rotation are used. A multi-axis sliding mesh is adopted for the rotation of the rotor, and calculations with multiple rotating bodies in the computational grid are performed. In addition, we use the motion computational domain (MCD) method to represent the free motion of the octrotor flying car by the motion computational domain itself. Using the above method, we will show the appropriate rotation method from various rotor stop patterns, demonstrate the safety of the octrotor flying car, and clarify the behavior of the aircraft and the surrounding flow field.
