GAS EJECTION DEVICE WITH A SILENCER FEATURE

摘要

An ejection system comprises a flat fishtail nozzle opening into a flat fairing open at both ends to form therewith a static pump or ejector. The nozzle is subdivided into a succession of elementary nozzles producing a laminar jet of hot gases, and the fairing is likewise subdivided into as many separate juxtaposed elementary ducts as there are elementary nozzles. Each such elementary nozzle is associated with a respective elementary duct to form therewith an elementary static pump.
