Unsteady aerodynamics play an important role in aircraft response, aircraft loads, vibration environments and flight systems analysis; this role is becoming more significant with the advent of active control technology (ACT). For internal flows in engines, turbomachinery and helicopter rotors, unsteady aerodynamics are dominant features. The course provided a basic understanding of a range of related unsteady flow phenomena relevant to aeronautical applications, an awareness of the current state-of-the-art of prediction methods, and an appreciation of how unsteady aerodynamics are applied to contemporary practical problems. The course covered the following areas: a qualitative understanding of the character of unsteady flows at subsonic, transonic and supersonic speeds, including viscous effects for both attached and separated flows; an outline of the contexts in which unsteady aerodynamics are required for aircraft stability and control, flutter, aircraft dynamics response, ACT, turbomachinery vibration and helicopter rotor operation; a survey of the state-of-the-art of the current prediction methods with particular emphasis on recent developments in unsteady transonics, and a description of contemporary experimental techniques and apparatus.
