P&WC begins compressor demo for next-generation regional turboprop engine; 20% improvement in fuel burn

Pratt & Whitney Canada (P&WC) has begun testing of the compressor for the next generation regional turboprop engine, a key step in the company’s technology demonstrator program. The high-efficiency compressor is a core element of the new engine and the test hardware has already run to the full range of aerodynamic design points.

Key engine characteristics such as component efficiency and pressure ratio will be validated by the demonstration program, bringing the best technology forward. Pratt & Whitney Canada is a United Technologies Corp. company.

The next generation turboprop engine is a totally new centerline engine that will deliver a 20 per cent improvement in fuel burn over today’s fleet using the latest technologies of our next generation product families. Our new engine will deliver the economic and environmental benefits that will sustain the regional turboprop’s competitive advantage for airlines serving short-haul, high-frequency routes.

—Richard Dussault, Vice-President, Marketing, P&WC

P&WC’s PW100 family of engines has led the regional turboprop segment since entering service more than 25 years ago. The company has more than 200 million hours of flying experience in the regional turboprop segment.

P&WC’s new offering will be a fully integrated propulsion system including engine, nacelle, propellers and engine systems, bringing the most advanced systems integration technologies to this product.

What a fantastic improvement 20 % lower fuel burn: that in turn means increased payload, increased range and less pollution and cost.

As a former alum of P & W, I can tell you such advances don't come easy. It was an industry that would fight and claw for 1.5%, but 20% says to me multiple breakthroughs may have occured. For competitive reasons, we may not get a glimpse of all of them in and in detail until it is ready for certification. Maybe snipets along the way. However, note in this press release the compressor is headed to the test rig. One may ask when do the combustor, and turbine section go to their respective rigs, and what % of the gains they account for as well as the Compressor. Although this is the Canadian divison may I say to them and the East Hartford Guys and Gals, good luck and make it happen! G_dspeed!!!!

After 25 years, the time is right for Bombadier to upgrade their Q400 turboprop. A total 35% (20% + 15%) fuel consumption reduction would be possible.
