Abstract
An energy protecting device for three and four-engined aircraft includes a detecting unit configured to detect failure of each engine. A control unit is configured to provide a protective function by controlling maximum thrust of each engine. A triggering unit is configured to monitor a plurality of parameters and trigger the control unit to provide maximum thrust at predetermined conditions of the monitored parameters. An inhibiting unit is linked to the triggering unit and is configured to inhibit the protective function, when at least one of the engine on the wings of the aircraft has failed. The control unit is also configured to control the engines that have not failed to minimize thrust imbalance.
Claims17
An energy protecting device for an aircraft having a fuselage and a wing on each side of the fuselage, with four engines arranged in pairs on each wing, said device comprising:
- a detecting unit configured to detect failure of each engine;
- a control unit configured to provide a protective function by controlling maximum thrust of each engine;
- a triggering unit configured to monitor a plurality of parameters and trigger said control unit to provide maximum thrust at predetermined conditions of said monitored parameters;
- and
- an inhibiting unit linked to said triggering unit and configured to inhibit activation of said protective function, when the two engines arranged on a common wing of the aircraft have failed,
- wherein said control unit is further configured to control the two engines that have not failed to minimize thrust imbalance of the aircraft fuselage upon triggering by the triggering unit.
An energy protecting device for a three-engined aircraft having a fuselage and provided with one engine arranged on each wing and an additional engine arranged on the fuselage, said device comprising:
- a detecting unit configured to detect failure of each engine;
- a control unit configured to provide a protective function by controlling maximum thrust of each engine;
- a triggering unit configured to monitor a plurality of parameters and trigger said control unit to provide maximum thrust at predetermined conditions of said monitored parameters;
- and
- an inhibiting unit linked to said triggering unit and configured to inhibit said protective function, when at least one of the engines which is arranged on the wings has failed,
- wherein said control unit is further configured to control the engines that have not failed to minimize thrust imbalance of the aircraft fuselage upon triggering by the triggering unit.
