Turbine engine assembly comprising a nose cone and a front shroud

An assembly for a turbine engine extending about a longitudinal axis (11), comprising:

• a nose cone (20) comprising a conical body (22) extending about the longitudinal axis (11) or an axis parallel to said longitudinal axis (11) and a flange (23) arranged downstream of the conical body (22), in the gas flow direction, said flange (23) comprising a first contact surface (24) extending into the extension of an inner surface (25) of the conical body (22),
• a front shroud (21) comprising a generally annular body (26) extending about the longitudinal axis (11) or the axis parallel to said longitudinal axis (11) and a flange (27) arranged upstream of the annular body (26), in the gas flow direction, said flange (27) comprising a first contact surface (28) extending into the extension of an outer surface (29) of the annular body (26), the first contact surface (24) of the nose cone (20) being in contact with the first contact surface (28) of the front shroud (21),
• fasteners (30) configured to clamp the first contact surface (24) of the nose cone (20) flange (23) against the first contact surface (28) of the front shroud (21) flange (27),
• said assembly being characterized in that the first contact surface (24) of the nose cone (20) and the first contact surface (28) of the front shroud (21) are inclined from upstream to downstream, in the gas flow direction, towards the longitudinal axis (11), so that the flange (23) of the nose cone (20) grips the flange (27) of the front shroud (21).
