Abstract
A turbine engine motor having an unducted fan and a plurality of guide vanes, each guide vane being made of composite materials configured to be fixed to at least one inner fixed structure of a turbine engine, each guide vane including an aerodynamic blade extending radially outwards along a radial axis, an outer radial end, and an inner radial end. Each guide vane can have an inner platform configured to be fixed to the inner fixed structure and connected to the inner radial end by an inner connecting elbow and extending from the inner radial end along a single first tangential direction, secant to the radial axis of the aerodynamic blade.
Claims4
A turbine engine motor having a propfan, the turbine engine motor comprising:
- a plurality of guide vanes made of composite materials, each guide vane comprising:
- an aerodynamic blade extending radially outwards along a radial axis, the aerodynamic blade having an outer radial end and an inner radial end;
- and
- an inner platform configured to be fixed to the inner fixed structure and connected to the inner radial end by an inner connecting elbow and extending from the inner radial end along a single first tangential direction, secant to the radial axis of the aerodynamic blade, the inner platform comprising an opening for receiving a radial fixing system for independently fixing each of the vanes to the inner fixed structure;
- and
- a reinforcement element arranged radially between the inner platform of each of the vanes and the inner fixed structure,
- wherein each of the guide vanes are fixed only to an inner fixed structure of the turbine engine motor.
