A system for discharging the heating fluid from an anti-icing device in the air intake of a turbojet engine at a low pressure and with a high degree of mixing

摘要

The hollow casing (4) which constitutes the air intake of a turbojet engine has an outlet for the hot air which is used to prevent ice from forming on the front lip of the casing. The outlet is constituted by a plurality of slots (15) which are arranged and shaped in a manner such that they generate a low-pressure jet of hot air which undergoes a high degree of mixing with the external air and is consequently cooled so as not to burn the panels constituting the outer wall of the engine housing immediately downstream of the hot-air outlet.
