Description

Measuring the pressure distribution around an aerofoil profile immersed in a flow teaches students the fundamental knowledge for developing effective lift on the aerofoil. In order for lift to occur on a body immersed in a flow, there must be low pressure on the underside of the body and high pressure on the upper side. The pressure distribution on a body immersed in a flow is clearly demonstrated with this experiment.

HM 170.22 with the airfoil profile NACA 0015 – used in the wind tunnel HM 170 – allows the pressure distribution to be recorded. As further aerofoil profiles are optionally available NACA 54118 (HM 170.26) and NACA 4415 (HM 170.27).

The aerofoil is used in the wind tunnel’s force sensor. The angle of attack is varied by rotating the mount. The surface of the aerofoil is fitted with measuring holes, which are arranged so that interaction is virtually eliminated. Each measuring point is fitted with a hose connection. The aerofoil is enclosed by two side panels to prevent secondary flows.

The static pressures are displayed on the tube manometers HM 170.50 or in the electronic pressure measurement HM 170.55.
