Abstract
A method for managing unbalanced thrusts caused by engine failures in an aircraft provided with a distributed propulsion system, the distributed propulsion system including 2N powertrains (PTi), with N a strictly positive integer and i an integer lying between 1 and 2N inclusive, distributed symmetrically in relation to a plane of symmetry of the aircraft, according to which the power of at least one powertrain belonging to a first side of the plane of symmetry is reduced when a failure occurs in a powertrain belonging to the opposite side, such that the sum of the moments of the thrusts generated by the powertrains in relation to the center of gravity of the aircraft is nil, to within regulatory tolerances.
