Pratt & Whitney Canada's PW200 engine is the turboshaft engine of choice in Asia, according to the company. The PW200 family powers aircraft such as the H135, AW109E Power, AW109 Grand, Bell 427 & 429, Kazan Ansat and MD Explorer 900 series.
The engine has flown more than 9 million hours, according to P&WC VP of Marketing Irene Makris.
The PW200 engine requires minimum maintenance and has low operating costs. 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 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.
