IIRC, the XF-91 was built just before aero engineers discovered the advantages of shock attachment for supersonic flight. The flat inlet causes a shock, which adversely affects performance. |

It was an attempt to build a 'jet-rocket' rather than a pure jet: http://www.network54.com/Forum/47898...g+other+treats. shows some photos. Wikipedia: http://en.wikipedia.org/wiki/XF-91 |

Wikipedia: http://en.wikipedia.org/wiki/XF-91 My memory seems to thing that the X2 (or was it D558?) had both rocket and jet engines for a while. That from Bill Bridgeman's autobiography? |
