The PW300 turbofan engine family is the engine of choice for new generation mid-size jets thanks to its outstanding reliability, durability, and operating economics. The PW300 family comprises 4 engine series and 9 models, ranging from 4,700 to 7,000 pounds thrust, with more than 2,700 engines produced having accumulated over 6.9 million flight hours. The PW300 is P&WC’s first total integrated propulsion system including engine, nacelle and thrust reverser and is built with the latest technologies to deliver highly dependable, fuel-efficient power for its long range business jet applications. Low emissions TALON™ combustion and advanced shock management fan technologies also ensure clean, quiet performance. Furthermore, the latest full-authority digital engine control (FADEC) in many of the PW300 models provides reduced pilot workload and advanced engine health monitoring/diagnostics assuring a high standard in aircraft dispatch availability.
Operators of PW300 engines 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, more than 100 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.
PW300 engines incorporate the latest advanced technologies in the drive to exceed our customers’ expectations in performance, reliability, durability, fuel consumption and environmental friendliness. Nine PW300 models have been produced (PW305 to PW308C) ranging in thrust from 4,700 to 7,000 pounds. The PW300 is a two-spool engine with a five-stage high pressure compressor driven by a two-stage, cooled high pressure turbine and a three-stage low pressure turbine driving a robust, advanced technology fan. A high efficiency through-flow combustor, with advanced TALON™ combustion in the latest models, ensures low emissions and fuel consumption. A high efficiency exhaust mixer further contributes to the engine family’s low fuel burn and noise. The latest Full-Authority Digital Engine Control (FADEC) in many of the PW300 models provides reduced pilot workload and advanced engine health monitoring/diagnostics, assuring a high standard in aircraft dispatch availability. The result is a compact, light weight design that powers the majority of worldwide mid-size business jets.
