Abstract
A helicopter with a turbine power unit on which fluid flow from the turbine exhaust nozzle, from a turbine bypass duct, from a duct communicating with the compartment housing the turbine engine, and from one or more ducts for cooling internal parts on the helicopter, converges inside a single manifold the output of which is connected to the input of a tubular screening device extending outwards from the manifold and provided with tubular transverse wing contours communicating externally and arranged in such a manner as to prevent the turbine exhaust nozzle from being directly visible from outside, and in such a manner as to define a number of ejectors for activating the fluid streams converging inside the manifold, and for mixing them together with outside air.
