Cascade assembly for a jet engine thrust reverser

Abstract

A cascade assembly for a jet engine thrust reverser comprising an inflow cascade, an outflow cascade, and fasteners. The inflow cascade has a plurality of inflow vanes, a plurality of inflow strongbacks, and a front inflow flange. The outflow cascade has a plurality of outflow vanes, a plurality of outflow strongbacks, and a front outflow flange, wherein each of the plurality of outflow strongbacks are parallel to each other. The fasteners extend through the front inflow flange and the front outflow flange.

Description

technical field [0001] The present disclosure relates generally to aircraft, and more particularly to aircraft with jet engines. Still more particularly, the present disclosure relates to a cascade assembly for a jet engine thrust reverser and a method for forming the cascade assembly. Background technique [0002] Aircraft with jet engines are often equipped with thrust reversers, which increase drag on the aircraft during landing, thereby reducing the aircraft's speed. Thrust reversers increase drag by effectively reversing the flow of exhaust through a jet engine. In one type of thrust reverser called the cascade type, a thrust reverser transcowl (transcowl) on the jet nacelle translates back to expose a cascade of open grids. Closing of the blocking door causes a bypass portion of the airflow passing through the engine to be diverted through a series of circumferentially arranged cascade vanes in the grille oriented to redirect the airflow forward, thereby producing re...

AI Technical Summary

Problems solved by technology

[0003] Manufacturing of cascade grids is time-consuming, labor-intensive and therefore expensive

Current cascade grids are manufactured using fiber-reinforced thermoset resins, which require many processing steps and specialized equipment
