Telescoping centerbody wedge for a supersonic inlet

摘要

An aircraft engine two-dimensional inlet system of the present invention provides a telescoping two-dimensional centerbody that is referred to as a wedge. The telescoping wedge may be of a fixed wedge angle design or a variable wedge angle design. The present invention contemplates single and multi-wedge angle designs of the fixed or variable intermediate wedge angle types having more than one ramp angle. The telescoping wedge has at least one upper and lower pair of longitudinally adjacent wedge forward and aft walls that overlap to form an aft facing step and are in controlled sliding engagement.
