A nacelle inlet for an engine. The nacelle inlet includes an inner flow surface, an outer flow surface, and a turbulator segment positioned along the inner flow surface. The turbulator segment extends outward beyond the inner flow surface and is configured to transition laminar airflow along the inner flow surface upstream from the turbulator segment to turbulent airflow downstream from the turbulator segment.

An aircraft engine cowling comprises a first cowling portion and a second cowling portion moveable relative to each other. A cowling latch secures the first cowling portion and the second cowling portion in a closed position. The aircraft engine cowling further comprises a deflection limiter band and a deflection limiter latch moveable between an engaged state and a disengaged state for the deflection limiter band. An interlock mechanism prevents disengagement of the cowling latch while the deflection limiter latch is in the engaged state. The interlock mechanism includes a lock element moveable between a first position that prevents disengagement of the cowling latch and a second position that enables disengagement of the cowling latch. The interlock mechanism also includes an indicator paddle movable to contact the deflection limiter latch. A linkage assembly coordinates movement of the lock element with movement of the indicator paddle.
