A blade () of a fan (), made of composite material, of a turbomachine. On a portion () of the blade () which extends from a lower limit () located at a predetermined distance (d) from the shank () of the blade equal to at least 80% of the predetermined height (h) to the top () of the blade (), a dihedral angle (D) measured at least one predefined point on the chord of the blade (), located on the chord of the blade () at the upstream end () of the nose () of the shield (), is greater than or equal to −3° and less than or equal to 0°.

Fan blade with zero tip dihedral at the head

The invention relates to a blade comprising a shield () attached to the upstream end of the body of the blade, the shield () comprising an upstream end forming a leading edge of the blade, the shield () further comprising a nose () upstream from which the leading edge is located, an pressure-face fin and an suction-face fin laterally attached on the blade, the fins extending from the nose, the blade comprising a defrosting air passage duct () arranged inside the nose and extending radially inside the nose, the duct () having an inner end () emerging opposite the root () and a radially external end emerging from the nose between the leading edge and its junction at the pressure-face fin.

The invention relates to a turbomachine assembly () comprising a fan () and a booster drum-type part (), the fan () comprising:&#x2014;blades () comprising an airfoil () and an extension () mounted on and attached to the trailing edge () of the airfoil (),&#x2014;a fan () disc () and&#x2014;a series of inter-blade platforms (), the extension () of each blade () extending beyond the downstream face () of the fan () disc () in the direction of the upstream edge () of the part () and covering, at least partially, the cavity () between the fan () and the part ().

Turbomachine assembly comprising fan blades with an extended trailing edge

The invention relates to a fan blink () for an aircraft turbomachine, comprising a hub, an annular platform () and fan blades () arranged projecting from the annual platform. It also comprises a mechanical discharge slit () from a trailing edge () of the fan blade, associated with at least one of the fan blades (), for the case of ingestion of a bird, the slit being made on the annular platform () going around the trailing edge ().

Fan for aircraft turbomachine

A turbomachine blade () comprising a body () and an elastomer gasket () fastened to said body ().

Turbomachine blade fitted with an elastomer gasket

The present invention relates to a turbine engine guide () vane (), with a height (H) extending between a vane root () and a vane tip () along a radial direction (Z), said vane () comprising a succession of five bulge portions along a tangential direction (Y) perpendicular to the radial direction (Z), this succession of bulge portions extending over the whole height (H) of the vane (), and the convexity of the successive bulge portions being alternately in one direction and in the other. The vane () has the advantage of having an eigenfrequency for the first striped vibration mode which is different from the urging frequencies of said vane (), during the operation of the turbine engine.

Turbine engine guide vane

The invention relates to a turbomachine blade comprising a vane. The vane comprises a leading edge, a trailing edge, a pressure face and a suction face spaced apart from each other and connecting the leading edge to the trailing edge. The vane further comprises at least one internal cavity between the pressure face and the suction face, wherein air is intended to flow. The vane comprises intersecting transverse partitions, downstream of the cavity, so that air can flow from the cavity in the direction of the trailing edge between the intersecting partitions.
