Is there a turbofan out there that can mechanically alter the bypass ratio in flight? Especially is there one in regular civilian use?

To learn things.

hindsight2020 said:whoa fellas, the SR-71 does not have a "variable bypass ratio" engine at all. Just like the MIG-21, they both have pure turbojet engines (read NO bypass) with variable GEOMETRY inlets.
9GClub said:It's also interesting to note how most intakes are offset a couple inches from the fuselage (perhaps most notably on the F-4/F-16) in order to avoid sucking from the boundary layer. If I'm not mistaken, the Raptor does NOT incorporate this design (i.e. the intakes are blended to the fuselage)..... wonder what the rationale is in that case....
