Commonwealth Aircraft Corp / CAC R795 Cicada

 

CAC designed the R795 Cicada which was intended to be used in the Winjeel. The Cicada was designed to be built using existing tooling that CAC had previously used to produce Pratt & Whitney R-1830 engines. The Cicada was a 7-cylinder geared radial engine of 795 cubic inch (13 litre) capacity; like the Pratt & Whitney R-985 that was eventually fitted to all Winjeels it developed 450 horsepower (340 kW). Because of its lower cubic capacity the Cicada was more complex (and thus significantly heavier) than the R-985 and also had higher fuel consumption. Only two development examples of the Cicada were ever built, one of which was actually fitted to Winjeel prototype (RAAF serial) A85-364. The two engines accumulated about 650 hours before the programme was terminated in September 1953.
