Controlling a relative position at an interface between translating structures of an aircraft nacelle

A nacelle for an aircraft propulsion system, comprising:

• a stationary support extending circumferentially about an axial centerline;
• a forward nacelle structure configured to translate axially along the centerline between a stowed position and a deployed position;
• an aft nacelle structure configured to translate axially along the centerline between a stowed position and a deployed position;
• and
• an interface assembly at an interface between the stationary support, the forward nacelle structure and the aft nacelle structure where the forward nacelle structure and the aft nacelle structure are respectively in the stowed positions, the interface assembly including a pair of interlocking components, wherein a first of the interlocking components is mounted to the forward nacelle structure at the aft end of the forward nacelle structure, and a second of the interlocking components is mounted to the stationary support.

A nacelle for an aircraft propulsion system with an axial centerline, comprising:

• a fanlet configured to translate axially along the centerline;
• a thrust reverser sleeve configured to translate axially along the centerline;
• and
• an interface assembly at an interface between the fanlet and the thrust reverser sleeve where the fanlet and the thrust reverser sleeve are respectively in stowed positions, the interface assembly including a plurality of interlocking components, wherein a first of the interlocking components is mounted to the fanlet at the aft end of the fanlet, and a second of the interlocking components is mounted to the thrust reverser sleeve at the forward end of the thrust reverser sleeve.
