An aircraft engine 1, for mounting on an aircraft wing, comprises a fan or propeller 7 attached to an axial shaft 3. The fan or propeller comprises a plurality of blades 16 arranged around the shaft of which at least one has an internal channel. The axial shaft has an internal channel formed therein that extends from an opening 15 at a front end towards, and in communication with, the channel in the blade(s). The opening can be selectively opened and closed so that air is received into the shaft channel when open and is diverted through the internal channel of the blade(s) and exhausted through a further opening. The channelled air is used for blowing over the surface of an aircraft wing to enhance lift at lower airspeeds.
