The Avro Canada TR.4 Chinook was Canada's first turbojet engine, designed by Turbo Research and manufactured by A.V. Roe Canada Ltd. Named for the warm Chinook wind that blows in the Rocky Mountains, only three Chinooks were built and none were used operationally. After being scaled up from 2,600 lbf (12 kN) to 6,500 lbf (29 kN), it would become the Orenda.
