Video transcript of a tour and test inside the GVPM wind tunnel at Politecnico di Milano. The creator (Jacopo D'Alesio - Jakidale) describes the wind tunnel's layout (two interchangeable test chambers: a small 4×4 m sports chamber and a large upper chamber), instrumentation (pressure sensors, Pitot tubes, balances, arrays of fans), typical test workflows (aerodynamic correlation, thermal/battery cooling maps, appendage/winglet tests) and a live test of a student-built electric motorcycle. The clip also covers the team's workshop (carbon layup, autoclave processing, machining), and reports specific technical details (fan power, speeds, chamber dimensions, measurement methods).

Questions this video answers

4 × 4 m (16 m²)

About 200 km/h (stated as a typical maximum), and the tunnel is ramped up to 50 m/s (≈180–200 km/h).

Two rows of seven fans (14 fans total), each fan rated at 100 kW; total 1,400 kW.

Reported width 14 m and height 4 m (length unspecified; useful test area described as a large rotating circle).

1) Correlation tests (compare numerical simulations to reality); 2) Thermal tests (battery pack cooling mapping); 3) Tests of small aerodynamic appendages/winglets.
