Lift and drag (resistance to flow)
Principle:
A) Objects of different cross-section and shape are placed in a laminar air stream. The drag is examined as a function of the flow velocity and the geometry of the objects.
B) A rectangular plate or an aerofoil in a stream of air experiences a buoyant force (lift) and a resistance force (drag). These forces are determined in relation to area, rate of flow and angle of incidence.
Tasks:
A) Determination of the drag as a function of:
1. the cross-section of different bodies,
2. the flow velocity,
3. determination of the drag coefficients cw for objects of various shape.
B) Determination of the lift and the drag of flat plates as a function of:
1. the plate area
2. the dynamic pressure
3. the angle of incidence (polar diagram)
4. Determination of the pressure distribution over the aerofoil for various angles of incidence.
