摘要:
An exemplary distributed propulsion system (110, 210) with thermal management includes two or more rotors (112, 212a-d) individually controlled by associated motors (111, 211a-d) and an input control (107) connected to the associated motors to demand the associated motors produce a demanded thrust, wherein a motor power output of each motor of the associated motors is independently controlled to produce the demanded thrust and to control a motor temperature of one or more of the associated motors.

A method of controlling a multi-engine aircraft (102) includes receiving input for commanded thrust and modifying the commanded thrust using a model of an incumbent powerplant (108) to generate a modified commanded thrust for matching aircraft performance with a new powerplant (104) to the aircraft performance with the incumbent powerplant (108). The method includes applying the modified commanded thrust to the new powerplant (104).
摘要:
Provided are systems and methods of controlling load share in a multi-engine propulsion system (200). A load share participation value (418) indicative of a load share participation regime for a first engine (106) may be received and a load sharing requirement control command (420) for the first engine (106) may be output. The load share participation value (418) may depend or be based at least in part on one or more operating conditions of a second engine (108). The load sharing requirement control command (420) for the first engine (106) may depend on whether the load share participation value (418) indicates a full-participation load share regime for the first engine (106), a partial-participation load share regime for the first engine (106), or a non-participation load share regime for the first engine (106).
摘要:
Methods and systems to electrically assist an internal combustion engine of an aircraft may be provided. A first bladed rotor may be rotated by a first internal combustion engine. Electricity may be generated from a first motor generator by rotating a first shaft of the first motor generator with the first internal combustion engine. In response to a predetermined event, such as an engine failure, mechanical power may be generated from the first motor generator instead of electricity. The mechanical power may be transferred to the first bladed rotor. The mechanical power may be generated by applying electricity to the first motor generator. The electricity applied is received from a second motor generator, where the electricity received from the second motor generator is generated by rotating a second shaft of the second motor generator with a second internal combustion engine that powers a second bladed rotor.

The invention concerns a device (1) comprising control means (3) for activating a protective function which consists in automatically controlling the engines (M1 to M4) so that they supply maximum power when the triggering conditions are fulfilled, and inhibiting means (8) for inhibiting the protective function solely when all the engines which are arranged on a common wing of the aircraft have simultaneously broken down.

Procédé pour déterminer une vitesse minimale de contrôle d'un aéronef. Selon ce procédé, au cours au moins d'un vol dudit aéronef, on mesure les valeurs de paramètres prédéfinis et à partir desdites mesures enregistrées dans une mémoire (3) et d'au moins une valeur de certification prédéfinie reçue d'une mémoire (9), on détermine une valeur de certification Cnfcertif du moment de lacet cnf créé par la coupure d'un moteur de l'aéronef, valeur qui sera utilisée pour déterminer la vitesse minimale de contrôle. Selon l'invention, à partir de valeurs mesurées du dérapage β et de la force latérale Cy, ainsi que d'une valeur de certification Cycertif, on détermine une valeur de certification βcertif (E1). De plus, à partir des valeurs mesurées du dérapage β, de la force latérale Cy et du moment de lacet Cnf ainsi que des valeurs de certification Cycertif et βcertif, on détermine ladite valeur de certification Cnfcertif (E2).
