Guy was in mechanical design, post-development, on the PW124 in the 1980s. The engine was the first growth step of the family, and the increased power meant increased heat, which affected certain parts in the turbines more particularly the high pressure turbine vane. The team was feeling the heat too and tried different solutions. Colleagues on the cooling team proposed a technology used in Pratt & Whitney’s larger engines. Since newly designed parts could not be delivered before four or five weeks, Guy designed a temporary solution.. He simulated the desired technology by modifying the existing high-pressure turbine vane, blocking some cooling passages with small metal rods and drilling holes at the vane leading edge. This allowed cooling air to flow through, creating the showerhead cooling effect. A cool solution!
Committed and dependable people like Guy Bouchard have helped build the P&WC traditions of innovation and excellence. Thank you, Guy.
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.
