Abstract
A nacelle assembly includes an inlet lip section having a highlight diameter and a throat diameter. One of the highlight diameter and the throat diameter is fixed and the other of the highlight diameter and the throat diameter is selectively adjustable in each of a first direction and a second direction relative to the inlet lip section to influence a contraction ratio associated with the inlet lip section.
