Numerical analysis by solving the three-dimensional Euler equations has been performed in order to investigate the complicated flow patterns or aerodynamic characteristics of the advanced turboprop (ATP) propeller with two types of spinner configuration. The governing equations are written for a rotating Cartesian coordinate system in terms of absolute flow variables. The solution algorithm used is an implicit approximate factorization method and resultant matrices are efficiently solved by LU-ADI scheme. Moreover, flux vectors are all treated implicitly in order to accelerate convergence.This solver has applied to study the effect of interference between highly swept blades and axisymmetrical spinner on aerodynamic performance of ATP propeller. Numerical results clearly captured overall structures of flow field such as shock formation and clarified that the selection of area-ruled spinner is important for aerodynamic design of an efficient turboprop.
