The 5,000 shp PW150A provides the 70- to 80-seat airline market with jet-like speed together with turboprop fuel efficiency, low emissions, excellent operating economics and P&WC’s trademark dependability.
PW100-powered regional turboprop aircraft consume 25 to 40 per cent less fuel and produce up to 50 per cent less CO2 emissions than similar-sized regional jets. As a result of increased energy costs and the rising global consciousness with respect to our environment, many airlines are renewing their fleets with PW100-powered aircraft leading to a surge in orders in recent years.
Built with a low parts count and equipped with a dual-channel, full-authority digital engine control (FADEC) and advanced diagnostic capabilities, the PW150A is also designed for ease of operation, maintenance and high dispatch reliability.
In 2007, P&WC delivered the 400th PW150A turboprop engine for the Q400.
Operators of PW150 engines together with all the members of the PW100 family are supported by P&WC’s industry-leading global customer support. This includes over 30 P&WC-owned and designated service facilities around the world, field support representatives on all major continents, a 24/7 Customer First Centre for rapid expert support, the most advanced diagnostic capabilities for this market and the largest pool of P&WC rental and exchange engines in the industry.
PW100 engines incorporate the latest advanced technologies in the drive to exceed our customers’ expectations in performance, reliability, durability, fuel consumption and environmental friendliness. PW100-powered regional turboprop aircraft consume 25 to 40 percent less fuel and produce up to 50 percent lower CO2 emissions than similar sized jets, with correspondingly lower greenhouse gases. 31 PW100 models have been produced ranging in shaft horsepower power from 1,800 shp to 5,000 shp. The PW100 is a three-shaft, two-spool engine. Low pressure and high pressure compressors are powered independently by cooled turbine stages. A third shaft couples the power turbine to the propeller through a reduction gearbox, optimized to establish the best combination of engine and propeller efficiencies. The result is class-leading fuel consumption and low green house emissions. The latest materials, design technologies and advanced engine control have enabled PW100 engines to regularly achieve more than 10,000 hours on-wing without a shop visit, an impressive dispatch reliability record and provide the pilot and maintenance crew with easy engine operation and maintenance.
