0 - 35 m/s

Square section of 2.2 m side and 17 m long for atmospheric boundary layer simulation.

Various balances and load cells from 1 to 6 components to measure forces and moments in a wide range of values, depending on the characteristics of the test.

Scanivalve pressure scanner system. Capacity to measure 1250 pressure taps simultaneously, in different pressure ranges, compatible with the tunnel capacities.

Pitot tubes + pressure capsules. Hot wire anemometry system, up to 4 components simultaneously. 1-component LDA system. 2D PIV system. High temporal resolution stereoscopic (3D) IVP system.

Installation for sectional tests on suspension or cable-stayed bridges, wing profiles, solar trackers, etc. Determination of critical velocities (VIV and flutter) and stability derivatives by measuring the response with a laser distance meter (8 instruments of this type are available).

Simulation of atmospheric boundary layer according to wind standards (Eurocode and ASCE).

1.5% (reducible to 0.5%)
