GENEVA, May 22, 2023 /PRNewswire/ -- Pratt & Whitney Canada, a business unit
of Pratt & Whitney, today announced that its new PW545D engine will power the
Cessna Citation Ascend, the latest addition to Textron Aviation's business jet
family. The engine was designed and enhanced for Textron Aviation to deliver
improved specific fuel consumption (SFC), thrust and time between overhauls
(TBO).
"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," stated Nicholas Kanellias, vice president, General Aviation. "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."
Building on the success of the PW545C, the PW545D incorporates new materials
and technology. These include:
A more efficient high-pressure compressor for increased flow,An enhanced
single-stage, high-pressure turbine module, andAn advanced exhaust mixer to
reduce fuel consumption and noise.
The new engine is also equipped with Full Authority Digital Engine Control
(FADEC) technology, which is included with many PW500 models. This enables the
Citation Ascend to integrate new auto-throttle technology that simplifies
control, maximizes efficiency and reduces pilot workload.
The engine supports digitally driven advanced health monitoring and
diagnostics, in combination with the FAST™ (Flight, Acquisition, Storage and
Transmission) system. With FAST™, the engine's full-flight data is
downloaded, stored and analyzed by experts, enabling deep insights and
predictive diagnostics to optimize engine performance and maintenance
requirements. Customers with FAST™ installed who are enrolled in Pratt &
Whitney's Eagle Service™ Plan (ESP™) pay-per-hour maintenance program may
take advantage of the 6,000-hour TBO option.
The PW545D engine will help provide Citation Ascend operators with the
flexibility to accomplish a variety of missions, including charter services,
personal transportation and corporate flights. It also delivers the impressive
reliability for which the PW500 has become known over the decades, with an
excellent track record of dispatch availability and reliability, complemented
by our comprehensive plans that lock in maintenance costs.
Along with other members of the PW500 family, the PW545D features a compact,
accessible design that facilitates installation and on-wing maintenance. It is
supported by Pratt & Whitney's industry-leading global service network. This
includes over 50 Pratt & Whitney -owned and -designated facilities, more than
100 Field Support Managers on all major continents, a 24/7 Customer First
Centre for rapid expert support and the largest pool of Pratt & Whitney Canada
rental and exchange engines on the market.
The PW545D can operate on blends of up to 50% SAF with conventional Jet A
kerosene. This is part of Pratt & Whitney Canada's ongoing efforts – in
collaboration with public and private parties – to lead the way in
developing sustainable solutions that will help the industry reach its target
of net-zero CO2 emissions by 2050.
This year, Pratt & Whitney Canada is celebrating 1 billion hours of flight for
its entire engine fleet. for which 350 million flying hours can be attributed
to powering Textron Aviation's fleet of aircraft.
