Kawasaki Delivers First Fan Drive Gear for Airbus A220's Engine

Kawasaki Heavy Industries has delivered the first Fan Drive Gear System (FDGS) to be fitted in the engine of Airbus A220 narrow-body, twin-engine, medium-range jet airliners.

Kawasaki participates in the PW1500G and PW1900G Geared Turbofan engine (GTF) programs for regional jet aircraft as a Risk & Revenue Sharing Partner with Pratt & Whitney (P&W). Kawasaki produces both the Fan Drive Gear System (FDGS) and the Combustor, which are critical components for the GTF. The GTF utilizes the FDGS to achieve a higher bypass ratio by changing the cycle speed between turbine system and fan module.

This first FDGS will be used for engine tests and FDGS production for commercial engines will commence soon.

PW1500G and PW1900G are both GTF engines. GTF engines feature a high bypass ratio　with an advanced gear system, delivering upwards of 16% fuel burn improvement, 75% noise reduction, and 50% lower NOx emissions compared with traditional commercial aircraft engines.

Kawasaki has been enhancing its technological development and production capabilities of gear-related parts since the development of the jointly collaborated Kawasaki & Airbus Helicopter Deutschland BK117. Kawasaki continues to invest in and grow its civil aerospace engine business through participation in joint development and production programs.
