DIVERGENT PETAL FOR GAS TURBINE ENGINE NOZZLE

摘要

Divergent petal for a gas turbine engine nozzle. This petal (2) is articulated in its front edge to a convergent petal (1), by means of a cylindric al joint (4) while its back surface is articulated at an intermediate point to a compression bar (5) by means of the cylindrical joint (6), the cylindrical joint s (4 and 6) being perpendicular to the engine axis. Petal (2) is composed of a traction bar (11) and a aerodynamic base plate (10) which forms the nozzle duct, both components being related one to the other by a front joint (13-16) which coincides with cylindrical joint (4) between convergent (1) and divergent (2) petals, and a rear joint (14-18) which coincides with with joint (6) between divergent petal (2) and compression bar (5), with said rear joint (14-18) being displaceable a certain distance in a direction functionally parallel to the base plate (10).
