The Power Behind Canadian Aviation
Born From Canadian Ambition
The Orenda was more than an engine. It was a bold step into the jet age.
The Avro Canada TR-5 Orenda was the first production jet engine developed by Avro Canada’s Gas Turbine Division. Designed in the years following the Second World War, it became one of Canada’s most successful aerospace engineering achievements, with approximately 4,000 engines of various marks produced during the 1950s.
Its story began in 1946, when the Royal Canadian Air Force sought a new all-weather fighter. Avro Canada turned to its recently acquired Turbo Research operation to develop the technology that would eventually become the Orenda.

CF-100 FEATURE
The Power Behind the Canuck.
The Orenda became the heart of Canada’s CF-100 Canuck, powering the twin-engine interceptor through the Cold War era. Early aircraft used Orenda 2 engines, while later variants received increasingly powerful Orenda 8 and Orenda 11 engines.
