Aircraft engine comprising a pod comprising, in sequence from front to back, an air inlet structure (6), fan cowls (7), thrust inverter cowls (8), and a nozzle (9), additional stiffening means are placed either in the air inlet structure (6) or between the fan cowls (7) and the thrust inverter cowls (8). This arrangement limits the clearance between fan cowls (7) and thrust inverter cowls (8), despite the pressure differences applied in flight on the air inlet structure (6), due to the aerodynamic air flow. This avoids the formation of an excessive paras...


The invention claimed is: 1. An aircraft engine including a fan casing and a pod, wherein said pod comprises, in sequence along the air flow direction: an air inlet structure fixed to the fan casing; at least one fan cowl; and at least one thrust inverter cowl fixed to the fan casing, wherein the pod further comprises: a releasable connection mechanism configured to releasably connect a front edge of the fan cowl to a back edge of the air inlet structure; and several rigid stiffeners of which one first end is fixed to the air inlet structure close to th...
