Impact of local wind conditions on Urban Air Mobility

This study investigates the stability of Urban Air Mobilities (UAM) departing from or arriving at virtual vertiports under varying flow conditions. The flow simulation for urban flow field in Jamsil, Seoul, Korea is reproduced with Large Eddy Simulation. Flight simulations based on a 6 degree of freedom model with departure and arrival courses are performed with a quadcopter-type UAM. Virtual vertiports with varying levels of average wind speed and turbulent kinetic energy are selected, near which the dynamic responses of the UAMs are studied. The results indicate that the arrival procedure in the UAM operations is significantly affected by the local wind condition than that of the departure. It also shows that the turbulence has a greater impact on vehicle stability than the average wind speed.
