hpghost,
I checked the magazine : they say "The
Pröll afterburner with nozzle closed, in reheat, will give 30
KG thrust. The
Pröll afterburner with nozzle open will give 20
KG thrust"
It sounds quite incredible, but with both effetcs of afterburner and variable exhaust nozzle, why not.. I'm plannig to build one for my F-14... but I'm still waiting for drawings from General Electric... [

Would anyone have drawing, I would be much interested.
