Sažetak
Propeller and its wake can significantly change the flowfield at the downstream lifting surfaces and therefore strongly influence its aerodynamic coefficients. The numerical model of the propeller presented here is based on Prandtl's lifting line theory, using set of trailing vortices which form propeller wake. Calculated undeveloped propeller wake is used for determination of aerodynamic interference of the propeller on the downstream lifting surface, wing or tail. This numerical model is suitable for implementation in component build—up method used in preliminary estimation of aerodynamic coefficients for various propeller aircraft configurations.
