Alfa Romeo 135 Tornado / 136
Alfa Romeo 135
The Alfa Romeo 135 Tornado was an Italian 18-cylinder radial engine designed by Giustino Cattaneo in 1934-35. The engine consisted of two nine-cylinder radial banks, similar to the Alfa Romeo 126. Cattaneo left Alfa Romeo in 1936, leaving the development to eng. Bossi and his staff. At the time of its first running in 1938 and 1939 it was the most powerful radial engine in the world, generating just less than 1492 kW (2000 hp) on 100-octane fuel, but the normal was 87 (1,200-1,600 hp).
Despite the obvious potential, this engine was affected by many reliability problems. Reliability was solved in 1939 but it suffered from overheating and vibrations, so seriously that it was rejected from service. By 1944 only an handful were made, and never fitted in a operational aircraft. Only around 150 units of this engine were manufactured.
