Abstract
An aircraft propulsion system includes an engine assembly including a fan that moves air, and a cowl that surrounds at least a portion of the engine assembly when the cowl is in a closed position. The cowl includes an outer surface arranged away from the engine assembly that provides an aerodynamic surface. The aircraft propulsion system also includes a cowl mechanism connected to the cowl and configured to guide the cowl along a movement path from the closed position to an open position. In the open position, an entirety of the cowl is arranged farther away from a horizontal plane passing through a rotating axis of the fan than in the closed position.
