  • Convergent-divergent flap pair for a variable-geometry turbojet engine nozzle, the flaps of which each comprise a cooling air circulation duct
    Patent number: 11739712
    Abstract: In a convergent-divergent flap pair for a turbojet engine nozzle of the variable-geometry convergent-divergent type, the convergent flap and the divergent flap including respective ducts for circulation of cooling air connected to one another to allow cooling of each of the flaps. The duct of the divergent flap includes an impingement cooling cavity defined by two walls of lateral ends provided with air passage orifices through which the impingement cooling cavity opens towards the outside.
