Exactly that. Incidentally, those engines are based on the R-R Derwent (virtually a carbon copy). At the start of the cold war, when UK was still the leader in gas turbine engine technology (yes, even the US got started by developing Whittle's original engines) the Russians thought to themselves, "Well UK will never sell us their engines, but we'll ask anyway". And UK did sell a batch, which nthe Russians then copied! Quite true.
So when the Korean War came along we had UK and Australia (with Gloster Meteors) and the US (Lockheed Shooting Star) all with, basically, R-R Derwent engines, flying against Soviet Mig 15s, also with R-R Derwent (copy) engines! True story.
BTW, when I was a lad in the RAF in Germany we had those as snow blowers. 2 were mounted on a sort of lattice work rig and they were pushed along by a "bowser" (big Leyland or Hanomag 8 wheeler tanker). If you opened the throttles too quickly, either the compressor would stall (engine starts blowing out the front, instead of sucking in) OR you could push the bowser backwards on an icy surface. All good fun.
Where did you get those pix Novocaine?
