Nacelle

A nacelle comprising:

• a cascade;
• an inlet cowling;
• an outlet cowling separated from the inlet cowling by a transverse split line, the cascade being radially inward relative to the outlet cowling, the outlet cowling including:
• a translating sleeve panel comprising an aft end and a first lateral side;
• and
• an outer fixed structure comprising a track and a first lateral side adjacent to the first lateral side of the translating sleeve panel;
• a forward thrust configuration where the aft end of the translating sleeve panel is in a first position relative to the outer fixed structure;
• and
• a reverse thrust configuration where the aft end of the translating sleeve panel is in a second position relative to the outer fixed structure, wherein the second position is longitudinally aft of the first position, wherein the outer fixed structure remains in the same position for each of the forward thrust configuration and the reverse thrust configuration, and wherein the translating sleeve panel slides along the track in moving between the forward thrust configuration and the reverse thrust configuration;
• wherein the translating sleeve panel is configured to expose the cascade in response to translating longitudinally aftward relative to the outer fixed structure via the track in moving from the forward thrust configuration to the reverse thrust configuration, thereby allowing air to be redirected in a forward direction via the cascade.

A method of reversing thrust of an engine fitted with a nacelle on an aircraft, the nacelle comprising an outlet cowling, wherein the outlet cowling comprises a translating sleeve panel, an inner translating sleeve panel, and an outer fixed structure, the method comprising:

• changing the outlet cowling from a forward thrust configuration to a reverse thrust configuration, comprising moving the translating sleeve panel and the inner translating sleeve panel longitudinally from a first position corresponding with the forward thrust configuration to a second position corresponding with the reverse thrust configuration without moving the outer fixed structure, wherein the second position is aft of the first position, wherein the translating sleeve panel is configured to move relative to the outer fixed structure by translating along a track on the outer fixed structure;
• exposing a cascade with the outlet cowling being in the reverse thrust configuration;
• and
• redirecting air within the nacelle and through the cascade in a direction that produces a reverse thrust with the outlet cowling being in the reverse thrust configuration.
