Examples apply numerical procedures for solving one-dimensional Euler equations to flow within a supersonic inlet
, a converging-diverging nozzle, and a piston tube, and flow past an expansion corner and a compression corner.
Both of the Blackbird's twin nacelles contain an engine supersonic inlet, the J58 engine with its afterburner, and an exhaust ejector nozzle.
Thus the Blackbird's supersonic inlet must provide subsonic flow to the J58 compressor inlet, over the full range of flight speeds.

To achieve high performance levels, the mixed-compression inlet will need to operate close to its stability limit, much closer than military supersonic inlets
. This requirement highlights the importance of the inlet control system on the inlet design and the ability of the inlet to handle atmospheric disturbances and inlet unstarts.
