A regulator device for automatically regulating a power plant of a rotary wing aircraft having a turbine engine includes a computer system. The computer system, while implementation of an idling mode of operation of the turbine engine is requested and the aircraft is standing on ground, implements the idling mode of operation and operates the turbine engine in compliance with idling mode of operation as a function of operational and hierarchically ordered conditions either through a first mode of regulation by regulating a speed of rotation (Ng) of a gas generator of the turbine engine or through a second mode of regulation by regulating a speed of rotation (NTL) of a free turbine of the turbine engine.

Device for automatically regulating aircraft power plant gas generator and free turbine speeds as a function of heating, electricity generation, noise emission, and fuel consumption

The present invention relates to a method of increasing the safety of a power plant provided with at least one heat engine and a gearbox (BTP), the engine driving the gearbox (BTP), the gearbox (BTP) having a lubrication system implemented using an aqueous medium stored in a reserve, in which method a fluid comprising water is injected into the heat engine to increase the power developed by the heat engine without increasing the temperature of a member of the heat engine or to decrease the temperature without modifying the power developed by the engine, the fluid being taken from the reserve.

Method of increasing the safety of a power plant, and a power plant suitable for implementing the method

A method of automatically regulating a power plant (') of an aircraft (), said power plant comprising at least one turbine engine (), said aircraft () having at least one rotary wing () provided with a plurality of blades () having variable pitch and driven in rotation by said power plant (&#x2032;), it being possible for each engine () to operate in an idling mode of operation and in a flight mode of operation. During a selection step (STP), a two-position selector () is operated either to stop each engine () or to set each engine () into operation. During a regulation step (STP), each engine () is controlled automatically so as to implement the idling mode of operation if the collective pitch (CLP) of said blades is less than a threshold and if the aircraft () is standing on the ground.

Method of automatically regulating a rotorcraft power plant, a rotorcraft power plant, and a rotorcraft

The present invention relates to an automatic method of regulating a power plant (') of an aircraft (), the power plant having at least one turbine engine (), each engine () being capable of operating in an idling mode of operation. A calculation system () executes stored instructions in order to implement the idling mode of operation as a function of operational and ordered conditions either via a first regulation mode by regulating a first speed of rotation (Ng) of said gas generator (), or via a second mode of regulation by regulating a second speed of rotation (NTL) of said free turbine ().

Method of automatically regulating aircraft power plant gas generator and free turbine speeds as a function of heating, electricity generation, noise emission, and fuel consumption

A method of optimizing the performance of a rotary wing aircraft having at least one turbine engine with a gas generator and a turbine assembly comprising at least one turbine. In a definition step (STP), first and second performance levels are defined for the aircraft. During a health check step (STP), a first power margin is determined as a function of a speed of rotation of said gas generator and a second power margin is determined as a function of a temperature in said turbine assembly. During an evaluation step (STP), each power margin is compared with a first threshold in order to determine whether a target performance level is equal to the first performance level or to the second performance level. During a display step (STP), the target performance level is displayed.

The present invention relates to a method of increasing the safety of a power plant () provided with at least one heat engine () and a gearbox (BTP), said engine () driving said gearbox (BTP), said gearbox (BTP) having a lubrication system implemented using an aqueous medium stored in a reserve (), in which method a fluid comprising water is injected into said heat engine () to increase the power developed by the heat engine () without increasing the temperature of a member of the heat engine (), or to decrease said temperature without modifying the power developed by the engine (), said fluid being taken from said reserve ().

A method of controlling a group () of engines developing a necessary power (W) for driving a rotor (), said group () of engines having at least one electrical member (), electrical energy storage means (), and a first number n of engines () that is greater than or equal to two. A processor unit () executes instructions for evaluating a main condition as to whether the group of engines can develop the necessary power while resting one engine, and if so for resting one engine and accelerating a second number engines not at rest, and for causing the electrical member to operate in motor mode, if necessary, the electrical member operating temporarily in electricity generator mode when the storage means are discharged.

An aircraft power plant () having at least two engines (), each co-operating with respective control means () including respective memories (), each memory () containing information for causing said engine () to operate with a plurality of distinct utilization envelopes at iso-damage. Said power plant () includes determination means () for determining a first utilization envelope () for application during a takeoff stage of flight and a second utilization envelope () for application during a cruising stage of flight following the takeoff stage of flight, and a third utilization envelope () for application during a landing stage of flight following the cruising stage of flight.

Aircraft power plant, an aircraft, and a method of piloting said aircraft

A method of assisting the piloting of an aircraft () comprising a first rotor () having a plurality of first blades () with a first variable collective pitch, and a second rotor () having a plurality of second blades () with a second variable collective pitch. According to the method, a computer determines a power limit curve () and displays said limit curve () in a diagram () to inform the pilot of the first and second collective pitch margins available before reaching the limits of at least one operating rating of the power plant of the aircraft.
