ABSTRACT:
The assembly comprises a collector nozzle which is fixed to a turbine engine and which is elbowed laterally towards the exterior and which debouches into injection nozzles which are also elbowed and which open into a mixer masked laterally by means of a fairing, of which a shaped forward section defines, with an internal shaped screen and a central plug, a semi dynamic principal air inlet. The aspirated air dilutes the gas in the mixer which is terminated by means of an elbow directed upwardly and which can pivot about a transverse axis. In the position of maximum deviation upwardly this elbow masks the hot parts of the assembly from the rear. The assembly is particularly useful for equipping helicopters with lateral exhaust gas turbine engines, and it can be original equipment or retrofitted. The assembly serves to reduce the infra red emission from the helicopter, to defeat infra red homing missiles.
