The invention relates to a nacelle for aero-engines. An air inlet channel of the nacelle for aero-engines is connected with a fan casing of an engine; the air inlet channel and the fan casing are respectively provided with an air inlet channel spherical peripheral part and a fan casing spherical peripheral part, which can be in relative sliding contact; the air inlet channel and the fan casing are connected through at least three sets of actuating mechanisms, and the actuating mechanisms are generally and uniformly distributed in the peripheral direction. Each actuating mechanism comprises an air inlet channel hinge, a fan-casing hinge and an actuator; the air inlet channel hinge and the fan-casing hinge are respectively arranged on the air inlet channel and the fan casing; one end of the actuator is connected to the air inlet channel hinge and the other end of the actuator is connected to the fan-casing hinge, so that the air inlet channel and the fan casing are connected together. The nacelle for aero-engines has the beneficial effects that the flowing state of the air entering the air inlet channel on the condition of maneuvering flight of aircrafts and crosswind is improved; the separation of boundary layers is lowered; the aerodynamic loss is reduced; the air intake efficiency is improved; the efficiency of the engine is further improved.
