Jet Glider Sparrowhawk

I had no appreciation for how much water was injected until I saw the fire
go out in a KC-135 engine one day when they hit the water after throttle up.
Quite a splash.

The water was injected into the combustion chamber, not the exhaust.
Evaporation increased the pressure in the chamber without increasing
temperature too much. In the 70's, there has been a spectacular accident
of
a Lockheed Tristar outbound Hamburg where the mechanics put fuel ino the
according tanks instead of water - resulting in all three engines failing
during the initial climb, and the aircraft passing underneath a bridge of
a
local highway. Partially passing, that is :-(

Early models of the KC-135 tanker used water injection
on takeoff for added thrust. No idea how much additional
thrust could be gained by adding this to a 45Lb thrust
turbine but it wouldn't increase fuel consumption the
way an afterburner would. How about a cowling around
the jet and water could be sprayed or misted onto the
exhaust section. Could the steam then mix with the
exhaust well enough to increase thrust or would it
be a perpetual motion add on?

If not, you can add the afterburner! (re-heat)
