Blackbird Motor

The SR-71 that is located in the Evergreen Aerospace Museum is configured to give some interesting views of the aircraft.  One side of the aircraft is opened up to show the engine.  The whole of the outer portion of the wing folds up to give access to the engine.  I had no idea that was the way it operated until I saw this plane.  It does show the engine configuration nicely.  At the high supersonic speeds, there is a bypass process whereby a lot of the flow is taken around the core.  The pipes for this can be clearly seen along the side of the engine.
