Velocette Posted April 1, 2021 Report Share Posted April 1, 2021 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.

cardigun Posted April 2, 2021 Report Share Posted April 2, 2021 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. Quote Link to comment Share on other sites More sharing options...
