Abstract
An air inlet of an aircraft nacelle includes a pipe, extending over the circumference of the air inlet and defined in the back by a front frame, and an element for the localized injection of hot air into the pipe, thus ensuring the flow of hot air into the pipe in one direction along the circumference of the nacelle. The inlet includes at least one vortex generator () in the pipe (), the generator being plate-shaped or shaped in a manner projecting from the wall of the pipe (), in order to disrupt the hot air flow so as to compensate the effect of the centrifugal force and reduce the temperature gradient between the inside and outside of the pipe ().
