Before you begin, you may want to read the laboratory manual and then experiment manual.

This is a 5 m Ealing air track system with glider velocity monitors, pneumatic driver and magnetic glider release.  The sensor separation is 3.695 m.
This picture shows the other end of air track.  Some elementary principles of propellers, axial fans chocked flow and pressure drag are demonstrated using air supported gliders moving along the air track at approximately 1 m/s.
Drag, thrust and the viscosity of air may be obtained from analysis of the glider motion.  Software routines provided reduce the basic input data providing quick-look results
