I know about the basic dynamics of a center body exhaust, just wondering how/why it has been in and out of vouge? Most of the designs I'm aware of with them date from the '50s/early '60s.I'd wonder if the center bodies on these were fixed and the outer ring either expanded or traveled fore and aft for throttling. Or, like WWII German types, the center body moved.As for applications, does after-burning and/or bi-pass mixing need a larger/longer post-turbine volume? And consequencially, a more conventional variable exhaust nozzel?Or is it that the center body designs have/prefer/need less exhaust management?Just wondering, as I think they look particularly cool.
