Abstract
To provide aerodynamic continuity between the front part, pivoting with the rotor, and the stationary rear part of a pod housing an engine for driving the rotor, a curved cowl curved about the pivot axis extends the rear edge of the bottom cowling of the front part to join this rear edge to the front edge of a bottom cowling of the stationary rear part, in helicopter mode, and a flap swivel-mounted on the top cowling of the front part joins this latter to the top cowling of the stationary rear part, onto which this flap is folded, in helicopter mode.
