Aero engine discussion forum??


Recommended Posts

Hi, an odd request perhaps, but does anyone know of an aero engine discussion forum? I need assistance identifying a couple of engines.

Cheers

Prop or jet?

Put some pictures up.

I was thinking that it might be a **** and Whitney possibly.

You may well be correct, I was thinking back to my experiences with Boeing Steermans / Kadetts

Just as an aside, has anyone seen or knows how the crankshaft/big end is arranged on these rotary engines. it had me baffled until I got an old WW2 handbook for a Continental Red Seal Tank Engine, R-975EC-3 and all was revealed.

We have quite a few radials at work as my boss has a sideline making these.... sadly looks like yours is a little past it

No. That'll polish out.  😀

No chance, because the JSW pusher used a watercooled radial engine

There is a difference between a Rotary engine, such as the Le Rhone, and radial engines such as the P & W and Bristols.  Radial engines are static, and the propeller goes round.  Rotary engines go round with the propeller, and the crankshaft is bolted to the plane.

Rotary engines had Total Loss lubrication, because of the centrifugal force in a rotating engine, which is why many young pilots in WW1 smelt of Caster Oil.  They only had one speed, full throttle, because the linkage would be impossible.  They controlled the plane with a Stop Switch, which cut out the ignition when operated. You will remember the sound track in WW1 films of planes taxiing with the engine note cutting in and out.
