Interesting stuff

Gordon,

Without doing a lot of sums (which I have probably forgotten how to do), the best I can offer is:

58000 ft, M 2.0, Ambient temperature - 52 deg C, Ambient pressure 1.2 lb/sq.in
Engine intake conditions
Total pressure 8.5 lb/sq.in, Total Temperature 127 deg C, Mass flow 189 lb/sec.
Fuel burn 9700 lb/hr
Jet pipe exit (not final nozzle) Total pressure 16 lb/sq.in, Total Temperature 687 deg C
Engine thrust 8050 lb.

The jet pipe nozzle was choked of course and the petal angle was 10 deg, but I don't have the value of the actual area handy.

Clive
