Abstract:
The proposed invention is an air-flow straightening assembly for a turbine engine comprising:—a cylindrical platform ( 15 ) centred on an axis (X-X),—at least one straightener blade ( 20 ) extending from the platform,—a structural arm ( 30 ) extending radially relative to the axis, and—a mechanical member ( 40 ) protruding from the platform ( 15 ), said mechanical member ( 40 ) being one of the group comprising:—a radial shaft,—an angle transmission box of a radial shaft,—an electric, hydraulic or pneumatic connection element,—an intermediate gear driving a radial shaft, the straightening assembly further comprising a fairing ( 50 ) of the protruding mechanical member, the fairing having a three-dimensional surface defined by:—at least one upstream end pont (Ai, A e ) located axially upstream from the mechanical member ( 40 ) relative to the direction of air flow in the turbine engine, and—at least one downstream end point (Ci, C e ) located axially downstream from the mechanical member, the three-dimensional surface being tangential to the platform at the upstream and downstream end points (Ai, A e , Ci, C e ), and having a larger cross-section measured along an axis (Y-Y) orthogonal to the first, and in which the three-dimensional surface is further defined by two lateral end points (B i , B e ) corresponding to the ends of said larger cross-section respectively on the pressure side and suction side of the structural arm ( 30 ), the axial positions of said points being separated by at most 0.1 C OGV —in which C OGV  is the chord of the straightener blade ( 20 ).

Claim (Index 1):
A turbine engine air-flow straightening assembly comprising:\n a cylindrical platform centered on an axis X-X, at least one straightener blade extending from the platform, a structural arm extending radially with respect to the axis, and a mechanical member protruding from the platform, said mechanical member being one of the group comprising:\n a radial shaft, \n an angle transmission gearbox of a radial shaft, \n an electrical, hydraulic or pneumatic connection element, \n intermediate gear transmission of a radial shaft, \n wherein the straightening assembly further comprises a fairing of the protruding mechanical member, the fairing having a three-dimensional surface defined by:\n at least one upstream end point located axially upstream of the mechanical member with respect to the air flow direction in the turbine engine, and \n at least one downstream end point located axially downstream of the mechanical member, \n the three-dimensional surface being tangent to the platform at the upstream and downstream end points, and having a larger section measured along an axis Y-Y orthogonal to the axis X-X and tangential to a circle centered on the axis X-X, and wherein the three-dimensional surface is further defined by two lateral extreme points corresponding to the ends of said larger section respectively of the pressure and suction side of the structural arm, the axial positions of said points being distant by 0.1c OGV  at most, where c OGV  is the chord of the straightener blade.
