The PW200 family is the engine of choice for the new generation of light-twin helicopters having captured a majority share of worldwide sales over its competitors thanks to unprecedented levels of reliability and economy.
Ranging in power from 500 shp to over 700 shp, PW200 engines have been produced in 10 models and their versatility has been demonstrated in a wide variety of applications. PW200 engines power aircraft in service with 380 operators in 54 countries. More than 4,000 PW200 engines have been produced since the family entered service in the 1990s, accumulating more than 7 million flying hours in emergency medical service, utility, law enforcement, business and other operations.
Operators of PW200 series 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. P&WC’s helicopter engine support has also been consistently ranked No. 1 by operators in Pro Pilot magazine’s annual powerplant support survey.
The PW200 engines incorporate the latest technologies in the drive to exceed our customers’ expectations in performance, reliability, durability, fuel consumption and environmental friendliness. Ranging in power from 500 to over 700 shp, the PW200 is simple in concept, with only three major rotating components and a modular design enabling easy maintenance. A single-stage centrifugal compressor driven by a single-stage turbine with a PT6-style reverse flow combustor power a free, single stage power turbine. The power turbine, in turn, powers the output shaft through a front-mounted reduction gearbox. Combining the reduction and engine accessory gearbox contributes to the PW200’s compact design. The PW200’s control system features an Electronic Engine Control with full hydro-mechanical backup delivering pilot-friendly operation including auto-starting. Low fuel consumption, light weight, a compact architecture, low environmental emissions, minimum maintenance and low maintenance cost are fundamental to the PW200’s sustaining appeal in the marketplace.
