The Pratt & Whitney Canada PW545D engine has been specifically designed and enhanced for Textron Aviation, offering improved specific fuel consumption (SFC), thrust, and TBO.
Raytheon Technologies has announced that Pratt & Whitney Canada, a division of Pratt & Whitney, with its new PW545D engine will be powering the Cessna Citation Ascend, the latest addition to Textron Aviation’s business jet lineup. The PW545D engine has been specifically designed and enhanced for Textron Aviation, offering improved specific fuel consumption (SFC), thrust, and time between overhauls (TBO).
The PW545D engine will offer operators of the Citation Ascend the flexibility to fulfill a wide range of missions, including charter services, personal transportation, and corporate flights. Its reliability is demonstrated by the PW500’s excellent track record of dispatch availability and reliability, complemented by comprehensive maintenance plans that help control costs.
Building upon the achievements of its predecessor, the PW545C, the PW545D incorporates new materials and technology. Notable enhancements include a more efficient high-pressure compressor for increased airflow, an enhanced single-stage, high-pressure turbine module, and an advanced exhaust mixer to reduce fuel consumption and noise. The engine is also equipped with Full Authority Digital Engine Control (FADEC) technology, enabling the integration of new auto-throttle technology in the Citation Ascend, simplifying control, maximizing efficiency, and reducing pilot workload.
Nicholas Kanellias, Vice President of General Aviation, Pratt & Whitney Canada said, “The PW500 turbofan family has established itself as the engine of choice for light to mid-size business jets thanks to its proven safety, reliability, and durability, attractive operating economics, and comprehensive maintenance plans. “The PW545D is the latest engine in this family. We injected all we’ve learned from the more than 4,600 PW500 engines produced to-date, which have accumulated over 22 million flying hours. This new engine is even more fuel-efficient, offers greater thrust and an increased TBO of up to 6,000 hours for eligible customers.”
Nicholas Kanellias further highlighted the advancements made in the PW545D engine, leveraging the knowledge gained from over 4,600 PW500 engines produced, accumulating more than 22 million flying hours. The PW545D engine offers increased fuel efficiency, greater thrust, and an extended TBO of up to 6,000 hours for eligible customers.
The PW545D engine supports advanced health monitoring and diagnostics through digitally driven systems and the FAST (Flight, Acquisition, Storage, and Transmission) system. The FAST system enables the engine’s full-flight data to be downloaded, stored, and analyzed by experts, providing deep insights and predictive diagnostics to optimize engine performance and maintenance requirements. Customers enrolled in Pratt & Whitney’s Eagle Service Plan (ESP) pay-per-hour maintenance program and equipped with FAST can take advantage of the extended 6,000-hour TBO option.
Pratt & Whitney’s PW500 family, including the PW545D engine, boasts a compact and accessible design that facilitates installation and on-wing maintenance. Customers can benefit from Pratt & Whitney’s extensive global service network, which includes over 50 owned and designated facilities, more than 100 Field Support Managers worldwide, a 24/7 Customer First Centre for rapid expert support, and the largest pool of Pratt & Whitney Canada rental and exchange engines available.
