FIELD: motors and pumps.
SUBSTANCE: controlled hot flap of axisymmetric nozzle of turbojet engine is arranged with the possibility of rotation around axis perpendicular to axis of turbojet engine and comprises pad from composite material with ceramic matrix and friction surface made of metal. Friction surface is arranged along width under flap pad, is intended for contact with nozzle gasket made of metal and is limited by two sides perpendicular to friction surface and intended for installation opposite to sides of adjacent slave flap. Friction surface is arranged as either integrated into controlled hot flap or on support part, which is manufactured separately and fixed on controlled hot flap.
EFFECT: reduction of nozzle gasket and flap friction surface wear, and also increase of tightness between slave flap and adjacent controlled hot flap.
