Synopsis:

Fundamental laws of high speed flows.

High speed flow in stream tubes at the delivery of mass, heat and mechanical energy. The effect of friction.

Particular types of supersonic flows (continuous expansion, shock waves).

Airfoils and wings at high speeds (subsonic, transonic and supersonic zones). Pressure distribution, the influence of Mach number on aerodynamic characteristics (lift, drag, pitching moment).

Specific features of transonic flows.
