Review of Dynamic Wake Models For Application to Dynamics and Stability of Rotorcraft
Abstract
Since the introduction of dynamic inflow in the early 1970's, a fair amount of attention has been given to rotor induced flow models that are hierarchical and can be presented in state-space form. The original, heuristic, 3-state models of the 1970's gave way to the Pitt-Peters models of the 1980's that were hierarchical and could have as many as 8 states. In the late 1980's and early 1990's, the Peters-He models became completely hierarchical with as many states as desired. In more recent years, the emphasis has been on amending the model to include curved wakes, ground effect, and previously neglected states. Part of this development has necessarily involved computation of flow off of the rotor disk by the state-space approach. This paper reviews the developments up until now.
