PROPELLER BLADE ICE ANALYSIS

Atmospheric phenomena can influence flight safety through a series of manifestations of the air masses in the flight area. Such a dangerous manifestation is the icing that can seriously affect the performance of aircraft and lead to flight events. The article draws attention to the phenomenon of icing as located on propellers, a phenomenon which is analyzed on both a 2D (aerodynamic profile) and a three-dimensional (three-blade propeller) geometry, using the Qblade freeware tool, and in the case of icing formed on the NACA 0009 leading edge. The aerodynamic analysis proposed for comparison provides graphical and numerical data relevant for an assessment of the degree of influence of icing deposits in the analyzed case, the proposed geometries and the generated numerical data can be exported and exploited later, by using software analysis tools.
