  • Noise control chevron for a nozzle, and nozzle and turboshaft engine provided with such a chevron
    Patent number: 8887489
    Abstract: According to the invention, the shape of each of said chevrons is defined: by two lateral sides (21, 22) having front ends (21A, 22A) that are connected to said nozzle (4, 10) and that, when moving away from the latter, converge towards each other without joining so that the rear ends (21R, 22R) of said lateral walls (21, 22) are spaced from each other; and by a curvilinear transverse line (23.1) connecting the rear ends (21R, 22R) of said lateral walls (21, 22) by forming two rounded side protrusions (24.1, 25.1) separated by an intermediate rounded recess (26.1).

  • AIRCRAFT PROPULSION SYSTEM COMPRISING AN AFT PYLON FAIRING WITH LATERAL WALLS THAT ARE PROFILED FOR INJECTING COOL AIR ALONG A THERMAL PROTECTION FLOOR
    Publication number: 20140191080
    Abstract: The invention proposes to protect a rear part of a floor of an aft fairing of a pylon of an aircraft bypass turbojet engine using a film of cool air formed of part of a bypass flow of the jet engine which is guided under the floor by two lateral wall portions of this fairing which have been profiled for this purpose. To do that, these two lateral wall portions delimit respective air passage spaces formed between a forward part of the floor and a jetpipe of the turbojet engine and which open laterally and towards the rear.
