Abstract
This relates to a helicopter in which the outlet nozzle from the turbine engine is provided with an exhaust pipe which mixes the combustion gases with fresh air and directs the mixture downward. Viewed from the outside of the helicopter, the exhaust pipe is completely concealed by a cowling which is separated from said exhaust pipe by an empty intermediate space, air intakes being provided to create a flow of ambient air, including during hovering flight, along the intermediate space as far as an outlet which is open substantially vertically downward.
