Title:
DE-ICING DEVICE FOR AN AIR INTAKE OF AN AIRCRAFT TURBOJET ENGINE NACELLE, AND ASSOCIATED METHOD
Document Type and Number:
WIPO Patent Application WO/2023/232828
Kind Code:
A1
Abstract:
The invention relates to a de-icing device for an air intake of an aircraft turbojet engine nacelle, having at least one injector (3) for injecting a stream of hot air (FAC) comprising a peripheral member (30) which internally defines a passage channel (4). The peripheral member (30) comprises a peripheral mouth (31) which is configured to inject a peripherally formed stream of hot air (FAC) so as to cause a stream of cold air (FAF) to circulate in the passage channel (4). The peripheral member (30) has an interior guide wall (301) which is radially flared in the downstream direction, the interior guide wall (301) being located downstream of the peripheral mouth (31). The stream of cold air (FAF) circulates inside the peripherally formed stream of hot air (FAC) in order to make mixing possible between the stream of hot air (FAC) and the stream of cold air (FAF).
