Reliability of measurement: our n°1 concern
We started by spending hours checking the repeatability of our measurements with a variability to remain below 1%.
Validation by a velomobile:
To validate our technology, we carried out tests on fully enclosed velomobiles. In such a way as to have no possible aerodynamic variation coming from the measured object.
These tests showed that Aeroscale has an extremely low intrinsic variability of less than 1%. Concretely this corresponds to 0.001m² of Cda (or 1W of aero power at 45 km/h), which represents only 0.4% for a time trial rider
Here are the results of the 16 passages made:
This is to date (to our knowledge) the lowest variability and highest accuracy recorded for an outdoor testing device.
Fineness of measurement:
To test our solution, we voluntarily added aerodynamic disturbances on a fixed drag velomobile. Thus, Aeroscale is able to discriminate very small differences in aero, like a tennis ball, as illustrated below:
