PR: Pratt & Whitney Canada today unveiled its latest turboprop engine with a new centerline that delivers 33% more power at altitude and reduces fuel consumption by 20%, compared to previous generation engines. The engine, which amassed more than 14,000 development hours, was recently certified by Transport Canada. Pratt & Whitney is an RTX business.
“The PT9 engine represents the next evolution of turboprop propulsion, delivering significant advances in performance, efficiency and adaptability to meet the needs of modern aviation,” said Satheeshkumar Kumarasingam, president, Pratt & Whitney Canada. “Designed around evolving customer needs, including advanced digital capabilities and future-ready hybridization, its architecture can be tailored to diverse airframe types and provides a strong foundation for continued innovation and technology integration.”
The PT9 engine combines jet-like performance, turboprop efficiency and advanced digital intelligence in a next-generation architecture designed to provide more capability today and evolve with the aircraft of tomorrow. Its modular construction sets the foundation for continued innovation and technology integration, including electric aircraft and hybrid thermal-electric powerplants. The PT9 engine is ideal for high-demand missions and can be easily tailored to diverse airframe types.
Production will take place in Lethbridge, Alberta, Canada, which is also the company’s global Center of Excellence for the PT6 family of turboprop engines.
Notes:
Look at the image, aptly named ‘teaser’. Beyond a few key numbers- 33% more power at 20% lower fuel burn- we know very little.
- New centerline engine. The company designed and tested it in a five-year development program kept quiet throughout, aimed at new-generation single- and twin-turboprops. It is the company’s first all-new turboprop in decades. aviation week
- Power class. The outlets give slightly different ranges. Aviation Week reports an initial target of 1,700–2,300 shp, slotting between the biggest PT6 models and the lower-rated PW100 engines. FlightGlobal says 1,700–2,000 shp, in the 2,000 shp (1,490 kW) class. Aviation Week, FlightGlobal
- Performance claim. P&WC claims 33% more power at altitude and 20% lower fuel burn versus previous-generation engines. The baseline is “current engines in its class,” which isn’t defined. rtx
- Technology. It uses materials and technologies carried over from the PW800 turbofan and the PW127XT. Aviation Week
- Testing. It has logged more than 14,000 development hours. Investing
- Hybrid readiness. The construction is modular, so P&WC can add future technology, including electric and hybrid thermal-electric powerplants. However, Kumarasingam says the PT9 has no connection to the thermal engine concepts in P&WC’s hybrid-electric program. Investing, Aviation Week
- Relationship to the PT6. Kumarasingam emphasizes the PT9 is not a PT6 replacement. Aviation Week
- Production. It will be built in Lethbridge, Alberta, which is also the PT6 Center of Excellence.
Regulatory trail
- The certification designation is PT9A-11. P&WC first asked the FAA for an exemption in June 2024, withdrew the request, and later refiled a nearly identical one.
- That exemption covers shaft overspeed rules and asks to exclude complete rotor shafts. The filing pointed to advances in high-pressure compressor and turbine technology.
- The FAA validation date remains undisclosed.
What remains unknown
P&WC hasn’t named which aircraft will use the engine. No launch customer, entry-into-service date, or production rate has been announced. Stage counts, pressure ratio, SFC figures, and dry weight are not public. TBO and the maintenance or support model haven’t been released.
Our read
The ~1,700–2,300 shp band covers much of the ground above the PT6A-67/-68 ceiling. That includes heavier single-engine utility and special-mission aircraft, King Air 350-class twins, ag aircraft, and military trainers.
Unveiling a certified engine with no airframe announced usually means an OEM program is behind it under NDA. That makes the first airframe announcement the thing to watch. If it’s Pilatus, Textron, or Daher, it could come quickly. Timing this with NBAA is a signal.
