The Physics of Trailing Edge Blowing for Lift Control

Abstract

The project investigates the fundamental physics governing the lift enhancement of an aerofoil through through tangential blowing around a curved trailing edge. In particular, the research will focus on the behaviour of a wall jet at the rear of a flat plate wing. To investigate the problem, a suitable test-rig will be designed, constructed and fitted with suitable pressure instrumentation. After commissioning of the rig, a series of initial tests will evaluate the effect of various flow parameters, such as wing chord length, Reynolds number and jet momentum, on the behaviour of the wall jet and the potential control authority. The aim of this short project is to demonstrate the feasibility of the experimental approach and gain initial insight into the relative significance of various flow parameters in order to set the foundation for a longer, and more detailed, study which will be funded separately.
