Thrust reversal assembly for controlling sidewardly diverted flow

In a thrust reverser for a jet engine mountable on an aircraft in spaced relationship therewith, the engine having a longitudinal axis and a forward flight direction, the engine comprising a central engine body and a peripheral cowling spaced away from the engine body to define with it an annular flow channel for cold air flow, the cowling provided with an inner air flow surface and an outer air flow surface, the cowling further provided with at least one lateral vent which is lateral relative to the longitudinal axis, the thrust reverser comprising in combination:

• at least one thrust reversing door having an upstream edge, a downstream edge, an inner skin and an outer skin;
• means for attaching the door pivotally to the cowling;
• pivoting means for moving the door between a cruising position wherein the door closes the lateral vent and the inner skin and the outer skin constitute fairing elements with the inner and the outer air flow surfaces of the cowling respectively, whereby flows over said surfaces are unimpeded;
• and
• a thrust-reversal position wherein the door shuts the annular channel and the lateral vent is opened to divert the cold air flow sidewardly out through the lateral vent;
• the thrust reversing door characterized in that it is provided on its said upstream edge with a deflecting structure projecting substantially perpendicularly to the door to guide a portion of the diverted cold air flow sidewardly relative to the longitudinal axis, the deflecting structure comprising in combination:
• a sole plate attached fixedly to said upstream edge,
• a stiffener connected rigidly to and in spaced relationship from the sole plate to delimit therebetween a passage,
• a plurality of sidewardly oriented deflecting vanes each connected rigidly to the sole plate and to the stiffener in the passage.
