Claim 0:
1. An aircraft comprising a primary propeller driven in rotation by a motor, the motor having a first assembly and a second assembly movable in rotation relative to each other along an axis of rotation, the primary propeller being secured in rotation to one of said first assembly and second assembly, said aircraft comprising a locking system, comprising a housing and an indexing element, the housing being formed in one among the first assembly and the second assembly, the indexing element being secured to the other among the first assembly and the second assembly, the locking system having an engaged configuration in which the indexing element is at least partially inserted into the housing, and a free configuration in which the indexing element is not at least partially inserted into the housing, the locking system being configured such that, in the engaged configuration, the rotational movement of the first assembly relative to the second assembly is limited to a predetermined angular sector, the locking system being configured so as to switch from the engaged configuration to the free configuration when the motor applies a rotational torque greater than a torque threshold value on the first assembly or on the second assembly, wherein the first assembly and the second assembly are movable in translation relative to each other along a direction of translation defined by the axis of rotation, between a rest position and a service position, and in that the locking system can be in the engaged configuration only when the first assembly and the second assembly are in the rest position, wherein the predetermined angular sector is less than 5°.
