A Cat
 

Is this where I throw a cat amongst the pigeons and say I'd love to have a P-43 Lancer (both USAAF and RAAF) and a P-35?:D

They'd be interesting "what-if" planes, like the CW-21 and I'd certainly fly them if someone modeled them, but realistically they saw almost no combat service and proved themselves to be "less than outstanding" designs.

The Chinese used a few P-43s to no real effect, the P-35 saw limited use in the defense of the Philippines in 1941/early 1942, but that was it. In the game, they'd mostly serve as moving targets for Zeroes and Oscars.

The Japanese had a squadron of 2 seater versions of the P35 that was operational.

I have seen P47s fly many times...

A photo I took a couple years ago at the Thunder Over Michigan air show.

Most of the ones currently flying are probably louder than WW2 operational birds as they are not using the turbo chargers.

Still, wonderful to see in flight.

At 2.06 you can see that the supercharger doors are open a bit.
It means that the intercooler is warm so the supercharger is in use on this p-47.

It's a turbosupercharger so... if the supercharger is in use does that mean by necessity that the turbo is also working?

The supercharger is mechanically powered by the engine and the turbo is driven by the exhaust gasses so both are working anyway.

The exhaust smoke you see at the front of the aircraft on start up is coming from the waste gate outlet. It's the waste gate that bipasses exhaust gas to control the amount of boost that the turbo produces.

The turbo exhaust outlet is that bump under the rear of the fuselage.

One of the give-aways that the turbo is still installed and operable is exhaust smoke coming from that rear outlet. EVen with the boost pulled way back for start up, there would still be some venting from the rear turbo exhaust ports.

Remember that turbo units for aircraft from this period are absolutely gigantic compared to the automotive turbo-superchargers that most folks these days are familiar with. The only place with enough room for it on a P-47 is in the rear fuselage, it and it's ducting take up almost all the available space back there.

The technically correct name for a "turbo" is turbosupercharger. It's just an exhaust gas driven supercharger, and if equipped it does not necessarily mean that the engine has a mechanically driven supercharger as well.

If an engine does have both it is commonly called a compound supercharged engine.

At least that is how I remember it.

I think we can see this in this vid, at ~0:23:

Yes indeed.
