Thrust reverser cascade and method of manufacture

Abstract

A thrust reverser cascade and a method of manufacture are provided. A thrust reverser cascade of an aircraft engine comprises a frame and a vane overmolded onto the frame. The frame and the vane eachcomprise reinforcement fibers in a thermoplastic matrix. A method is disclosed for manufacturing the thrust reverser cascade or another part comprising an aerodynamic surface configured to interact with a flow of fluid. The method comprises providing a first portion of the part and overmolding a second portion of the part onto the first portion where the second portion includes the aerodynamic surface.

Description

technical field [0001] The present disclosure relates generally to aircraft, and more particularly to thrust reverser cascades for aircraft engines and associated methods of manufacture. Background technique [0002] Aircraft engines are often equipped with thrust reversers, which increase drag and can slow the aircraft during landing. For a cascade-type thrust reverser, a transcowl on the nacelle of the aircraft engine translates aft to expose a cascade comprising multiple blades. The blocking doors allow bypass airflow through the engine to be directed through a thrust reverser cascade where vanes redirect the airflow forward to generate reverse thrust. [0003] Some thrust reverser cascades are manufactured using composite materials that require many process steps and specialized equipment. The manufacture of composite thrust reverser cascades can be time consuming, labor intensive and expensive. Expect improvements. Contents of the invention [0004] In one aspect,...
