| 发明名称 | Aircraft comprising at least one engine having contra-rotating rotors | ||
| 摘要 | The aircraft includes at least one engine having contra-rotating rotors, the engine or at least one of the engines having imbalances associated with at least one ellipse. The aircraft includes a means capable of controlling the engine or at least one of the engines such that, at a given engine speed, the large axis of the ellipse or at least one of the ellipses extends in a direction for which the vibrations generated by the engine or engines have a minimum intensity in at least one predetermined site, particularly in a predetermined area, of the aircraft. | ||

| 主权项 | 1. Aircraft comprising at least one engine having contra-rotating rotors, the engine or at least one of the engines having unbalances able to generate forces such that, when an addition of the forces is represented by a vector, the vector forms an ellipse, the aircraft comprising means capable of controlling the engine or at least one of the engines such that, at a given engine speed, the major axis of the ellipse or at least one of the ellipses extends in a direction for which vibrations generated by the engine or engines have a minimum intensity in at least one predetermined site, particularly in a predetermined area, of the aircraft. | ||
