the TR.4, which was later named the Chinook. Work on the TR.3 was later abandoned. In 1946 Turbo Research was sold to Avro Canada, and Boyd became the Chief Designer of what was known as their Gas Turbine Division. In September 1946 they started development of the much larger TR.5, which soon became known as the Orenda. The Chinook ran for the first time in 1948, but was largely abandoned by that point. The Orenda ran for the first time in February 1949, and matured into a superb design that was the most powerful production engine between 1949 and 1952. Over the next few years just under 4,000 examples would be produced, and used on a variety of designs including the Avro CF-100 Cannuck and Canadair versions of the F-86 Sabre. Boyd resigned from Avro on December 31, 1950 after the company started planning a major reorganization and suggested Boyd become a consultant. In 1951, he founded a consulting firm as Winnett Boyd Limited. At about the same time, he started working as a consulting engineer for the C.D. Howe Company, where he was responsible for the design of the National Research Universal Reactor, or NRU. The NRU operated at the Atomic Energy of Canada plant in Chalk River until 2018. The NRU was considered one of the world's finest research reactors and produced a large supply of isotopes, used for medical reasons. In 1956, Boyd began designing the Daniels-Boyd Nuclear Steam Generator (D-BNSG), a nuclear powerplant based on Farrington Daniels' pebble bed reactor design. After two years of promoting the D-BNSG, the project was ended. He later wrote on the topic, notably in The Nuclear Future of Canada in 1958/59. In 1959, Boyd became the first President of Arthur D. Little's Canadian affiliate in Toronto. He worked there until his retirement in 1981, while maintaining his work at Winnett Boyd Limited. Later interests Boyd attended the Pugwash Conferences in 1965 and 1967. Boyd was a founding member of the Canadian Association for the Club of Rome, which is also concerned with world affairs. Boyd ran for the Progressive Conservatives in the 1972 General Election in the York—Scarborough riding, but lost to the Liberal candidate, Robert Stanbury. He used this campaign to publicly discuss the capitalist ideologies of his friend, Louis O. Kelso. In 1974, Boyd co-founded BMG Publishing with Kenneth McDonald and Orville Gaines. BMG published eight books pertaining
