An aircraft electrical supply circuit including: a power distribution network, onboard the aircraft, for electrical devices located in an engine of the aircraft or near the engine; and a power supply generator built into the engine of the aircraft to supply AC voltage power to a deicing or anti-icing system. The power supply generator is connected to a thrust reverser electromechanical actuator by a rectifier for supplying DC voltage power to the actuator.

Power supply circuit for an aircraft de-icing system

A control system for controlling a plurality of distinct functions of a turbojet engine, each function being associated with a respective actuation device. The system includes: an electric motor adapted to supply mechanical energy to each of the actuation devices; an electronic control unit for the electric motor; and at least one switching device interposed between the motor and the actuation devices, the switching device(s) serving to distribute the mechanical energy supplied by the electric motor selectively to one of the actuation devices.

System for controlling a plurality of functions of a turbojet engine

The invention relates to a device for regulating the flow rate of fuel taken from a fuel circuit of an aircraft propelled by an engine. The device comprises: a positive displacement pump receiving fuel from a fuel circuit of the aircraft and delivering fuel at a flow rate that is proportional to its speed of rotation; a differential gear having a predefined transmission ratio, a first inlet mechanically coupled to the aircraft engine, a second inlet mechanically coupled to an electric motor/generator, and an outlet mechanically coupled to the positive displacement pump to drive it in rotation; and an electronic control system for regulating the speed of rotation of the electric motor/generator as a function of a setpoint value for the flow rate of fuel to be injected.

Regulating the flow rate of fuel taken from a fuel circuit of an aircraft propelled by an engine

An electrical power supply circuit in an aircraft is disclosed. The circuit includes an electricity distribution network on board the aircraft for powering electrical equipment situated in an engine of the aircraft or in the surroundings of the engine, and a power supply generator integrated in the engine of the aircraft for powering a de-icing circuit. The electrical equipment includes nacelle loads connected to a DC voltage distribution bus which is connected to a voltage converter circuit powered by the distribution network. The de-icing circuit includes at least one electrical resistance for dissipating electricity returned to the DC voltage distribution bus by at least some of the nacelle loads.
