PRATT & WHITNEY CANADA’S PW200 EMERGES AS HELICOPTER ENGINE OF CHOICE IN ASIA
Pratt & Whitney Canada’s PW200 engine is the turboshaft engine of choice in Asia. The PW200 family powers aircraft such as the H135, AW109E Power, AW109 Grand, Bell 427 & 429, Kazan Ansat and MD Explorer 900 series.
“The PW200 powers the majority of the world’s light-twin helicopters for a very good reason,” said Irene Makris, Vice President, Marketing, P&WC. “Entering into service in 1993, the PW200 has low fuel consumption, light weight, compact architecture and low environmental emissions. It’s at the top because no other engine can match its performance and reliability. It’s an exceptionally dependable engine that has flown more than nine million hours.”
The best in its class, the PW200 engine requires minimum maintenance and has low operating costs – factors which drive its sustained appeal in the marketplace. The PW200 and the PW206B are powering respectively the majority of the light twin helicopters flying in Asia Pacific and the H135 aircraft in this area.
Recently, several operators in the region have selected the PW206B3 engine for their new H135 helicopters for emergency medical services and training missions, including APL in Malaysia, STPI in Indonesia, Tohoku Air Services, and Hirata in Japan.
The powerful PW200 engine has 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 – powers a free, single-stage power turbine. The power turbine, in turn, drives the output shaft through a front-mounted reduction gearbox. Combining the reduction and engine accessory gearbox with an integral oil tank contributes to the PW200’s compact design. P&WC has produced nearly 5,000 PW200 engines powering nine different applications. There are approximately 3,500 PW200 engines currently flying in 80 countries around the world.
