Dominique was involved in the development and/or certification of the PW120, PW124 and PW127 and was senior project engineer for the PW150. Before he retired, he was responsible for the entire family of turboprop engines.
Dominique was an engineering specialist for the PW100’s fluid systems – one of the most complex air and oil systems ever developed at Pratt & Whitney Canada (P&WC). The PW100’s three-shaft engine requires an additional bearing compartment. As a result, the air and oil system is considerably more complex, quadrupling the number of internal chambers and passages to pressurize bearing chambers and ventilate turbine discs and blades. This led to innovations such as the introduction of the first carbon seals on a P&WC engine to minimize the amount of air used for the pressurization of bearing chambers.
PW100 is the engine of choice it is today thanks, in part, to Dominique Nadeau, who was a member of the P&WC team for 33 years prior to his retirement in 2013. He is one of the committed and dependable people who have helped build the P&WC traditions of innovation and excellence. Thank you, Dominique.
Over the course of 30 years, a great many people at P&WC have contributed to the immense success of the PW100. To celebrate the engine that revolutionized the global regional market, we issued an appeal and asked for the names of those who have left their mark on its design, build and evolution.
We received over 150 names! As planned, we picked 30 names for the 30th anniversary of a December day in 1984, when two P&WC PW120A engines powered the first commercial flight of a Dash 8-100 from de Havilland Aircraft, soaring to the sound of bagpipes from Sault Ste. Marie to Kapuskasing, Timmins and Sudbury in Ontario, Canada.
