Abstract
An engine nozzle construction having a flap nozzle at the end of an engine exhaust duct, said flap nozzle variably controlling exhaust flow providing a primary flow path, said flap nozzle being movable to a position to direct the exhaust flow from said exhaust duct into a peripheral chamber, said chamber having exit openings around it providing for a secondary flow path for the exhaust flow.
Claims12
In combination with an aircraft engine exhaust duct, a peripheral housing positioned around said exhaust duct forming a peripheral chamber, nozzle means being movable to control exhaust flow through said exhaust duct to provide a primary flow path, inlet openings located through said peripheral housing into said peripheral chamber for receiving exhaust flow from said exhaust duct, said nozzle means being movable to direct exhaust flow from said exhaust duct into said peripheral chamber through said inlet openings, outlet openings positioned in said peripheral housing to direct exhaust flow therefrom to provide a secondary flow path.
In combination with an aircraft engine exhaust duct, a peripheral housing positioned around said exhaust duct forming a peripheral chamber therewith, said peripheral chamber extending entirely around said exhaust duct, said peripheral housing having a front wall extending outwardly from said exhaust duct forming the forward end of said peripheral chamber and a rear wall extending outwardly from said exhaust duct forming the rearward end of said peripheral chamber, nozzle means at the end of said aircraft engine exhaust duct being movable to variably control exhaust flow through said exhaust duct to provide a primary flow path for direct forward propulsion, inlet openings located through the rear wall of said peripheral housing opening into said peripheral chamber for receiving exhaust flow from said exhaust duct and directing it into said peripheral chamber, said inlet openings being positioned outwardly of said exhaust duct, said nozzle means being movable to direct exhaust flow from said exhaust duct forwardly into said peripheral chamber thorugh said inlet openings, outlet openings positioned in said peripheral housing to direct exhaust flow from said peripheral chamber to provide a secondary flow path.
