VEA 100


Teaching suggested applications*

-        Study of a fan as a function of rotational speed

-        Comparison of a centrifugal fan and an axial fan

-        Measurement of electrical power to the motor, determination of efficiency.

-        Determination of pressure losses.

-        Use of a column multi-manometer for pressure measurements.

-        Measurement of pressures, flow rates and velocities for several points in the seam.

-        Use of a pitot tube.

-        Verification of the Bernoulli equation.

-        Determination of the Reynolds number.

-        Highlighting aerodynamic lines.

-        Aerodynamic studies, measurements of lift, drag and pitch moment as a function of the incidence and air velocity on a profile.

-        Study of the effects of stall on lift and on the pressures applied to the wing


The above educational applications are possible within the framework where all options are ordered with the VEA100 base bench.


TheVEA 100bench  is an aerodynamic tunnel for studying aeraulic systems. It can be connected to anaxial fan VEA 200 or centrifugal fan VEA 300(not included). It is possible to vary the speed of rotation of the fan and determine its characteristics according to the speed, suction and discharge pressures at the fan. The test vein and the fan are disconnectable, this allows to change the type of fan (axial or centrifugal). This bench will also measure electrical power, determine engine efficiency, measure pressure losses using a water column multi-manometer and measure air velocity with a pitot tube.

It is also possible to study wing profiles using a three-component balance  withVEA 400 force transducers (not included) with drag, lift and pitch measurement as a function of wing incidence and flow (two wings are provided, symmetrical and asymmetrical).

The VEA500 option is used to study pressure profiles on a symmetrical wing, including visualizing the effect of stall on wing lift. This option includes a water column pressure gauge displaying pressures at 18 measuring points spread over the intrados and extrados.

The rugged design of this equipment makes it perfectly suited for use in schools. Its anodized aluminum structure on multidirectional wheels with brakes gives it great robustness and flexibility of integration into your premises. The chassis is split into two parts with a flexible sleeve connection. The manufacture of this equipment complies with the European machinery directive.
