Lecture 5 - Fluids and flight

From the 1983 lecture programme:

The physical factors governing the motion of real fluids, as opposed to the frictionless fluids of earlier theory, were discovered only within living memory. Since then there has been tremendous progress in the ways engineers and scientists have added to our knowledge of fluids in motion, and have made good use of that knowledge to machines. We shall look at ideas of streamlined and turbulent flows, and the remarkable differences between subsonic and supersonic aerodynamics. We shall see how air keeps aeroplanes up, and how good design can reduce their drag. We shall also see how steam drives the steam turbines that drive the generators that make electricity, and how gas-turbines propel most large aeroplanes and many ships. And we shall enquire how golfers and cricketers can make good use of aerodynamics.
