Pratt & Whitney Canada Launches PW545D Engine

Issue: 2 / 2023

Pratt & Whitney Canada 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). 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, and
  • An 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, maximises efficiency and reduces pilot workload.
