1. • The book balances theory with measurement: wind-tunnel aerofoil data, rotor test rigs, flow visualization, particle-image velocimetry, and flight-test instrumentation supply the empirical basis for models. Leishman advocates a hierarchy of tools: momentum and blade-element for conceptual design; free-wake vortex methods for mid-fidelity predictions of wake-induced phenomena; and viscous CFD (URANS, LES) for detailed flow physics, especially where separation, shocks, or strong vortex dynamics dominate. He highlights model validation, grid and time-step sensitivity, and the need to couple structural dynamics for aeroelastic fidelity.
