Super Rhone (radial conversion)
[edit]
In the mid‑1920s, the Texas firm Tips and Smith purchased a large quantity of surplus American‑built Le Rhône rotary engines and converted them into air‑cooled radial engines[1][2]. During the conversion, balance weights were added the crankshaft, and a new mounting arrangement was fitted which reversed the orientation of the engine such that the induction pipes were opposite the propeller. The new mounting system also incorporated a revised induction system where the carburettor was fed by air draw in from the crankcase. This design cooled and scavenged the crankcase while heating the inlet air to the carburettor which helped to vaporise the fuel.[2]
The conversion to a radial configuration increased the engine’s output from 80 hp at 1,200 rpm to 120 hp at 1,400 rpm. The engine’s weight was 340 lb. During WWI, the Le Rhône 9C engines had been purchased by the War Department for 4,250 dollars each.[2] In 1926, the Super Rhone engines went on sale at a price of just 750 dollars.[3]
