OUTER ENGINE HOUSING REVERSING DEVICE DEFLECTING GRILLE Russian patent published in 2018 - IPC B64D33/04 F02K1/58 

FIELD: motors and pumps.

SUBSTANCE: invention relates to the field of aircraft engines and to the aircraft braking devices. Outer engine housing reversing device deflecting grille includes solid sections. Each of the sections is made of polymeric composite material and contains longitudinal ribs and transverse deflecting blades. By the front flange sections are attached to the reversing device load-bearing frame front former by means of detachable connection, and by the rear flange are connected to the reversing device load-bearing frame rear former by means of detachable connection. In each section the longitudinal ribs and transverse deflecting blades are made with thickness of 1.5–10 mm. Longitudinal ribs are configured to provide the reversing jets flow direction at an angle of β=0°–40° to the radial direction. Transverse deflecting blades are located at an angle of γ=40°–80° to the engine longitudinal axis.

EFFECT: invention is aimed at the reversing device operation reliability improvement, as well as the reversing device deflecting grille sections mounting / dismantling simplification.
