Jet Glider Sparrowhawk

Water injection works but glowing shock diamonds in an afterburners exhaust
would be cool. Noisy, but cool.

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)

Well, I've looked into canards, and as a previous
poster pointed out, modern canards sacrafice a bit of
efficiency over trailing tailbooms.

So if this is out, canting engines to the side, or down, seems
a good choice. Doing this with a single engine is awkward.
So perhaps the engine right out the tail?

Hmmm....

Look at Max Barel's "Graal" experimental glider in France.

Seems to work rather well.
