Reheat
 
I was asked about reheat and, since I've never flown FJ, couldn't answer.
(Water-meth injection in the Argosy RR Dart doesn't really count ;))
Can anyone please help?

Q about reheat from Ships Nostalgia PM:

Do you, in the a/c, hear that same incredible noise (as an external ground observer hears) or do you just 'feel' the 'engagement'?

Reheat
 
Noise, not really, but you feel a massive shove in the back if you're low(ish), slow(ish) and unloaded (low alpha). If you're in a hard turn ie combat or a climb, the feeling is a little less. At high level, similarly reduced as you tend to be at much higher Mach. Hope that helps. TTH.

TTH, Many thanks.

Unless, of course, you have intake ramps like a Tornado F3 and you get another little kick in the pants at around M1.2 :ok:

LJ, I think you may have been shortchanged there, I think thats the short stubby mud mover, not the GT variant.

Pedant mode off

I hear that reheat was used on the Jav if one wanted to go slower.....

C-130K had reheat.

Steak, fish 'n' chips, pies, curry, chicken kiev, hot dogs...

Not much noise, unless it broke - then we'd get quite cross and shouty.

Isn't it only fitted to American aircraft?

I heard the Italian Tornado was the only aircraft to have reheat in reverse thrust mode.

A lot of noise when the 'reheat' mod was introduced on the Chipmunk in the 80's ... mainly because the issue of aircrew thermal 'bunny suits' was withdrawn :}

Water Meth injection in the Dart may or may not count...
But accidental Water Meth instead of Demin Water into the Spey probably does - at least for the few seconds that the turbine survives :-)
