Pratt & Whitney Canada’s PW545D engine has achieved a significant milestone, having received type certification from Transport Canada Civil Aviation on May 9 2024. This certification marks a crucial step towards the engine’s entry into service, as it is set to power Textron Aviation’s new Cessna Citation Ascend business jet, announced in May 2023. Pratt & Whitney, a subsidiary of RTX, is responsible for this advanced engine’s development and production.
The PW545D engine introduces several technological advancements. It features an advanced mixer and improvements in the compressor and turbine sections, which contribute to lower fuel burn and reduced operating temperatures. Additionally, the engine is equipped with Full Authority Digital Engine Control (FADEC) technology, a feature common in many PW500 models. FADEC enables the Citation Ascend to incorporate new auto-throttle technology, simplifying engine operation, maximizing efficiency, and reducing pilot workload.
“As the latest derivative in the PW500 engine family, we look forward to the Ascend’s entry into service,” said Cedric Gauthier, vice president, Sales and Marketing, General Aviation, Pratt & Whitney Canada.“Certification was granted following 630 hours of engine testing, in addition to 230 hours of flight testing on the Ascend prototype test aircraft,” he further added.
The PW500 engine family, which the PW545D belongs to, has a strong track record. There are approximately 4,600 PW500 engines in service today, with over 5,000 units manufactured. The fleet has collectively flown approximately 24.5 million hours. Other aircraft in the Textron Aviation portfolio powered by PW500 engines include the Cessna Citation Bravo, Excel, XLS, XLS+, Ultra Encore, and Encore+. Beyond business jets, Textron Aviation also produces twin- and single-engine turboprops, many of which are powered by Pratt & Whitney Canada engines.
Pratt & Whitney Canada, as part of RTX, leverages the parent company’s extensive resources and expertise. RTX, with over 185,000 employees worldwide, is at the forefront of technology and science, driving advancements in aviation, engineering integrated defense systems, and developing next-generation technology solutions. The combined efforts of Collins Aerospace, Pratt & Whitney, and Raytheon within RTX are aimed at addressing the most critical challenges faced by global customers.
