Dynamic inflow modeling in rotorcraft flight dynamics is a means of accounting for the low-frequency wake effects under unsteady or transient conditions. This report considers dynamic inflow and its influence on some problems of rotorcraft flight dynamics. The bases of modeling range from a simple empirical formulation to an involved prescribed-wake, discrete-vortex analysis of a four-bladed rotor. The emphasis is on perturbed linear versions of inflow in matrix form and on the sensitivity of low-frequency stability and response to inflow. However, non-linear versions for use in time-history solutions are presented. Coverage also includes the areas of weakness, controversial notions, and the need for additional test data on rotor-body damping in forward flight for a better appreciation of the developments in modeling dynamic inflow.
