Strip Analysis:

The numerical simulation of a rotating propeller geometry entails a high computational cost. This is for two reasons: the mesh density increases considerably, over and above that of the airframe, when modelling propeller blades and the numerical simulation of rotating blades requires an unsteady calculation.

Nevertheless, not all studies require the same level of fidelity. The ARA Computational Aerodynamics Applied team offers a range of possibilities to model propellers according to the customer or application needs: from low-fidelity codes to different high-fidelity CFD advanced techniques used in the aerospace industry.

 The well established ARA strip code allows a low-fidelity rapid prediction of isolated,
axisymmetric, propeller performance at a very low computational cost. The strip
analysis, well-established in the propeller industry, is a very powerful tool for early
design stages and optimisation purposes, when a significant number of alternatives
need to be evaluated.
