This paper presents a study of wake vortex interaction modeling for urban air mobility. Wake vortex modeling approaches for fixed-wing aircraft and rotorcraft are investigated. A wake age model is developed that accounts for the temporal and spatial dissipation of the wake-induced downwash. A wake vortex model is developed for rotorcraft that accounts for blade flapping motion and cyclic pitch control to reduce the lift asymmetry. This in turn results in an equal lift circulation strength on the advancing side and retreating side of the rotor. Two wake vortex interaction simulations are performed to illustrate the modeling approaches.
