Orenda Engines

In 1942 they sent two of their researchers to the UK to take a survey of their efforts and report on what fields of study the Canadians should focus in order to avoid duplication.

[2] The company was formally incorporated on 1 July 1944,[3] set up in a disused section of the Research Enterprises Limited factories in Leaside, a neighbourhood of Toronto, Ontario.

[9] In the spring of 1946 the government decided to turn all engine development over to private industry, and sold Turbo Research to Avro.

[10] Paul Dillworth remained as chief engineer of the newly minted Gas Turbine Division, which was moved to Avro's plant just outside what is today Toronto Pearson International Airport.

Work on the TR.4 continued through this period, but in the summer of 1946, Avro Canada asked them to produce a new 6,500 lbf (28.9 kN) engine for their CF-100 Canuck interceptor design.

The resulting TR.5 Orenda design was essentially a scaled-up Chinook, with work continuing on the latter to bring the production and test teams up to speed.

The Canadair Sabre became a popular export item as well, with versions being sold to the West German, South African, Colombian and Pakistani Air Forces.

After some 7,000 hours of development testing, up to a simulated altitude of 70,000 feet (21,000 m) and a forward speed of Mach 2.3, the Iroquois program was cancelled, along with the Arrow on 20 February 1959.

Avro Canada would later disappear due to the cancellation of the Arrow, but Orenda had a major engine overhaul business that allowed them to survive.

Production of a derivative engine, the afterburning J85-CAN-15, began in 1967 when Canadair was licensed to produce the CF-5 aircraft, a version of the Northrop F-5, for the RCAF.
