Aerodynamic Information

This calculation generates aerodynamic performance outputs and loading along the span of the blade. A user must specify the following inputs to run a single aerodynamic information calculation:

Wind speed \(U\) [\(\bunit{m/s}\)]. A uniform wind across the rotor is assumed in this calculation.
The blade pitch angle \(\phi\) [\(\bunit{rad}\)] is fixed for the simulation.
The rotational speed of the rotor (low speed shaft) \(\omega\) [\(\bunit{rad/s}\)] is constant.

An example set of inputs for an aerodynamic information calculation is provided below for a simulation where \(\phi = -2 \bunit{deg}\), \(\omega = 22 \bunit{rpm}\) and the wind speed is \(U=12 \bunit{m/s}\).

Assumptions

Only the rotor is simulated during this calculation. The blade structure is assumed rigid. To ensure that the rotor loading is azimuth independent several features are disabled. It is not possible for the user to enable any of the disabled features.
