I've just enjoyed a Yak 52 aerobatic performance not far from my house, and I didn't even see it...
... but oh, the
sound of that thing!
From what I know, the engine is quite low revving, and the plane has a wooden paddle prop. Just hearing one pass overhead is wonderful. But when they do loops, there's a sensational low pitch rumble that sounds like no other plane as it goes over the top.
The Yak52 was used as a Russian trainer. The engine power settings were, I believe, expressed in percentages to prepare the pilots for flying jets. The fuel endurance was only 2½ hours - to stop the Russian pilots from defecting to the West.
The plane used lots of pneumatics for flaps/gear etc.
This pic shows the Yak 52 in flight. The gear is retracted, but it was designed like that so that it wouldn't be the end of the world if the pilot forgot to lower it for landing - maybe a busted prop?
Anyone here know any more about the Yak52?
The only other planes I could recognise without seeing are Concorde (for obvious reasons) and Boeing 777, which sounds rather different from other airliners - I don't know why.
