  • Patent number: 10151270
    Abstract: An engine cowling of an aircraft gas-turbine engine with a thrust-reversing device, with a core engine and a bypass duct surrounding the latter, and with a front cowling enclosing the bypass duct and a rear cowling movable in the axial direction, as well as with cascade elements arranged over the circumference which can be placed by a substantially axial movement into an intermediate space resulting from a movement of the rear cowling relative to the front cowling, characterized in that the cascade elements are connected directly to the rear cowling, that the rear cowling has a rounded outer leading edge and that the cascade element has at its rear area a flow-guiding element, in front of which several thrust-reversing stator vanes are arranged and behind which at least one flow stator vane is arranged whose curvature shape matches the rounding of the outer leading edge of the rear cowling.
