The invention relates to an aviation propeller (10) having a longitudinal axis (X), comprising a hub (12), an annular row of ductless upstream rotor blades (14) and an annular row of ductless downstream stator blades (16), each downstream stator blade (16) having a variable pitch, and wherein at least one of the downstream stator blades (16) is in a closed pitch configuration with respect to another of the downstream stator blades (16) because the at least one of the downstream stator blades (16) has a pitch angle (gamma) less than the pitch angle (gamma) of the another downstream stator blade (16).
本发明涉及一种具有纵向轴线(X)的航空推进器(10),其包括轮毂(12)、环形行的无导管上游转子叶片(14)和环形行的无导管下游定子叶片(16),每一下游定子叶片(16)具有可变俯仰,且其中所述下游定子叶片(16)中的至少一个相对于所述下游定子叶片(16)中的另一个处于闭合俯仰配置,因为所述下游定子叶片(16)中的所述至少一个具有的俯仰角(γ)小于所述另一个下游定子叶片(16)的所述俯仰角(γ)。
