@seaniam81 Uhm no it's really using exhaust gasses energy, same way like turbochargers, only it does not use that energy to drive another turbine, but actually drive a gearbox : A Turbo-compound engine is a reciprocating engine that employs a '' blowdown turbine to recover energy from the exhaust gases ''.
@barthoedemaker While turbocharges do use exhaust gas energy, they use that to compress incoming air, before it gets mixed with the gas. These are part of the induction system. The Turbo Compound uses the energy of the hot exhaust to spin a gearbox linked directly to the crankshaft. Two complete systems. This is where the flames come from. Not because of a rich mixture, or because there is a turbocharger (not that there was one) in the engines.
@Ms11565 The Connie never had turbochargers on the engines. The flames come from the Wright R3350's Turbo Compound design. The Turbo Compound would recover energy in the exhaust gas' and transfer that strait into the crankshaft using a gearbox. What you are talking about is a turbocharger. That uses exhaust gas to turn a turbine to compress thin air into more dense air. And the R3350's never had that.
That is an awesome plane! Queen of the skies!

Uh, is that flame normal? Thanks for a beautiful video! :)

@seaniam81 Heat alone doesn't drive turbines....you need airflow..aka exhaust gasses

@seaniam81 sort of turbo " idea " since normal turbo uses exhaust gas energy to

Beautiful view!
Connies were great.
I flew in "Aerovias Quisqueyanas". It made you feel like in World War II
Rugged, safe, military, beautiful sounds. just a great plane!

I flew in the seat just behind this one, same view almost, and this video takes me way back to 1959, when I was 7 yrs. old!
