초록 ▼

A thrust reverser for a long duct mixed flow fan jet engine having a nacelle formed by a fixed forward structure surrounding the fan, a rear fixed structure and a translatable inner and outer cowl therebetween, the nacelle surrounds the engine and forms a long by-pass duct therewith, a common actuator fixed to the translatable cowls to simultaneously displace them over the rear structure, blocker doors coupled to the inner translating cowls for deployment during thrust reversal into the by-pass duct into a blocking position to divert the airflow through the cascades placed into an opening uncovered when the translatable cowls are axially displaced.

In a high by-pass fan jet propulsion power plant of the type including a core engine, said by-pass fan, and a long duct nacelle structure formed by a forward fixed cowl structure surrounding a forward portion of said fan, an intermediate translatable cowl member surrounding an aft portion of said fan and a rear fixed cowl structure surrounding the remainder of said core engine, said long duct nacelle structure surrounding the entire length of said core engine for forming a long by-pass duct therewith, and creating a mixed exhaust flow for the by-pass air and the core engine exhaust gasses, a thrust reversing arrangement for reversing the fan flow in said by-pass duct, comprising: said intermediate translatable cowl member including an inner and outer translatable cowl members axially mounted between said forward and rear fixed cowl structures; blocking door means, a dual arm means pivotally coupling an intermediate portion of said blocking door means to said inner and outer translatable cowl members, said dual arm means being fixedly connected to said inner and outer translatable cowl members, for pivotally deploying said blocking door means in a continuously controlled manner into said by-pass duct during thrust reversal for blocking the air flow in said by-pass duct and diverting said air flow through an opening created by the translation of inner and outer translatable cowl members to the outside of said long duct nacelle structure during thrust reversal; means for pivotally coupling said blocking door means to radially inner wall of said by-pass duct and retaining said blocking door means in aid deployed position during said thrust reversing operation, a single actuating mechanism fixedly coupled to said inner and outer translating cowl members and said dual arm means for simultaneously and axially moving said inner and outer cowl members over said rear fixed cowl structure into a deployed position of said inner and outer translating cowl members and driving said blocker door means in a continuously controlled manner for pivotally deploying said blocker door means in said fan duct to its deployed position against and substantially perpendicular to the inner wall of said by-pass fan duct, and a common operating means comprising said dual arm means and said common operating means being fixedly coupled to a tie bracket means and said inner translatable cowl member for axially translating said inner and outer cowl members over a portion of said rear fixed cowl structure and uncovering thereby said opening to the outside of said long duct nacelle structure wherein said dual arm means is directly connected to said inner translatable cowl member and is indirectly connected to said outer translatable cowl member.
