摘要： The invention relates to a propulsion unit (1) for an aircraft, including: a turbofan (7); a nacelle (2) surrounding the turbofan (7), including an inner structure (17) surrounding a downstream compartment of the turbofan (7), consisting of two annular half-portions (19a, 19b); and means (27, 29) for moving said half-portions, which include a rail/guide unit and are shaped such as to move the half-portion (19a, 19b) between a working position and a maintenance position. The propulsion unit according to the invention is characterised in that the rail/guide unit (27) is shaped such as to space the half-portion (19a, 19b) radially relative to a longitudinal axis of the nacelle, during a translation movement of the half-portion (19a, 19b) and in that the moving means include at least one connecting rod (29) which is connected to the half-portion (19a, 19b) and to the turbofan (7) and which is shaped such as to rotate the half-portion about said rail (37).
