초록 ▼

A pod for a very high bypass ratio turbofan engine unit of the forward contrafan type suspended from a suspension mast under the wing of an aircraft comprises a generally cylindrical inner cowling surrounding the casing of the jet engine unit and a generally cylndrical outer cowling spaced outwardly of the inner cowling and defining therebetween the cold flow path in which the contrarotating fan propellers are located, the outer cowling being divided into three parts consisting of an openable forward casing surrounding the fan propellers and connected to the suspension mast, an intermediate casing rigidly connected to the engine casing by radial flow straightener arms disposed in the cold flow path to the rear of the fan propellers, and an openable rearward casing also connected to the suspension mast. The engine unit is attached to the suspension mast by first attachment means carried on top of the intermediate casing, and second attachment means provided on the rear part of the engine casing. Coupling means are provided for rigidly connecting each of the forward and rearward casings to the intermediate casing when the engine unit is attached to the suspension mast and the forward and rearward casings are both closed.
