Abstract: A method for controlling the fuel injection of a turbine engine using a fuel supply circuit. The supply circuit includes a pilot injection line and a main injection line. During a transition of the supply distribution between the pilot injection line and the main supply line, the method includes the following steps: a) determining at least a minimum value to be maintained for a pressure value; b) determining at least one hydraulic quantity of the supply circuit; c) based on the determined hydraulic quantity of the supply circuit, calculating a calculated fuel supply distribution value corresponding to the minimum value to be maintained; and switching the fuel supply distribution to the calculated fuel distribution value.

Abstract: The invention relates to a method for starting a turbine engine in cold weather, including a starting system intended for rotating a drive shaft of the turbine engine, the method comprising the following steps: —a pre-starting step in which a first starting signal is generated to control the drive shaft in a first direction of rotation about a longitudinal axis (X) and in a second opposite direction of rotation in an alternating manner; and —a starting step in which a second starting signal is transmitted to the starting system in order for the latter to drive the drive shaft of the turbine engine in a normal direction of rotation and in which the drive shaft is rotated until a rotation speed that causes the turbine engine to start.

Abstract: A turbine engine equipped with an electrical apparatus with rotor and an epicyclic reduction gear train, includes a sun gear driven by a drive shaft about an axis of rotation, a ring gear surrounding the sun gear and configured to drive a fan shaft about the axis, and an annular row of planet gears interposed between the sun gear and the ring gear and held by a planet carrier fixed to a stator housing of the turbine engine. The stator of the electrical apparatus is fixed to the stator housing with an annular member for apparatus support. The annular member includes elongate legs that axially traverse the reduction gear. The annular member includes a first annular element for fixing to an annular flange integral with the stator housing. The stator of the apparatus has a first annular fixing flange connected integrally to opposed longitudinal extremities of the legs of the annular member.
