The system has an airtight coupling (22) for a pipe delivering hot air under pressure to an injector (12) located inside the engine ring cowling to de-ice its leading edge. The coupling between the forward end (10A) of the pipe and the injector is in the form of a ball and socket joint with a cylindrical chamber (23) open at both ends (23A, 23B) and connected by its forward end to the injector, and a hollow pivot (24) on the forward end of the pipe, engaging by with the inside of the chamber through its rear end. The inner wall of the chamber has an anti-friction coating (28), e.g. of carbon or tungsten carbide, and the hollow pivot is made from a slightly elastic metal, or a rigid metal with an elastic coating (27). |
