Abstract:
A system and method is provided for an integrated aircraft turbofan engine outer flowpath ducting and front frame that minimizes assembly interfaces and reduces overall aircraft engine weight. The system and method provide an integrated turbofan engine outer flowpath ducting and front frame system that decouples the fairing/aerodynamic duties from the struts/weight bearing duties thereby enabling efficient distribution of mechanical load.
Abstract:
A thrust reverser system comprising a single row vane assembly is provided. The provided thrust reverser system is capable of meeting performance requirements for turbine engines with reduced weight and cost.
Abstract:
A thrust reverser system capable of providing high efficiency within a tightly constrained nacelle is provided. The thrust reverser system provides a displaceable internal door pivotally mounted within a transcowl. The displaceable internal door is rotatable about a pivot axis that is positioned aft of a front edge of the transcowl when the transcowl is in a deployed position.
Abstract:
A system and method is provided for coupling a nacelle inlet assembly to an engine fan housing structure that provides adequate clearance and access for removing a blisk fan from a turbofan engine. This is accomplished by utilizing a nacelle inlet forward compartment, referred to herein as the “D-lip”and an acoustic liner that are inseparable and removable as an integral unit, providing sufficient clearance for removable of the blisk fan. The nacelle inlet assembly may be slidably coupled to the engine fan housing structure, minimizing assembly interfaces and therefore overall aircraft engine weight.
Abstract:
A thrust reverser system for a turbine engine includes a support structure, a transcowl, a door, and an anti-rotation structure. The transcowl is mounted on the support structure and has an inner surface. The transcowl is axially translatable, relative to the support structure, between first and second positions. The door is pivotally coupled to the turbine engine, and has a forward edge and an aft edge. The door is rotatable between stowed and deployed positions when the transcowl translates between the first and second positions, respectively. The anti-rotation structure extends from the transcowl and is disposed adjacent to the aft edge of the door when the transcowl is in the first position and the door is in the stowed position. The anti-rotation structure is configured such that door rotation out of the stowed position only occurs subsequent to or concurrently with translation of the transcowl out of the first position.
Abstract:
A system and method is provided that combines fan bypass components and minimizes assembly interfaces in a turbofan engine. The system and method provide a front frame structure of reduced weight that slidably installs/removes from within the combined fan bypass components.
Abstract:
A system and method for reducing idle thrust in a translating cowl reverser system is provided. The provided system and method provide a partial deployment, or thrust reverser system intermediate position for a translating cowl thrust reverser system.
