The Avro Canada TR5 Orenda was the first production jet engine from Avro Canada's Gas Turbine Division. Similar to other early jet engines in design, like the Rolls-Royce Avon or General Electric J47, the Orenda nevertheless outperformed its rivals in most ways, and the Orenda-powered Canadair Sabres were among the fastest of all first-generation jet fighters. Over 4,000 Orendas of various marks were delivered during the 1950s, Avro's greatest engine success.
