The jointly owned Airbus and Leonardo subsidiary is marking its 40th anniversary at the Dubai Airshow, which opened on Sunday as the aerospace industry tries to secure momentum for a fragile recovery from the COVID-19 crisis.
Industry sources said ATR would announce a new variant of the Pratt & Whitney Canada PW127 engines that power its 42-600 and 72-600 family of turboprop planes.
ATR dominates the market for turboprops, which it values at some $80 billion over 20 years. The planes are seen as more efficient on short trips, especially when oil prices are high.
But ATR faces potential challengers including Brazil's Embraer, which is weighing plans to launch an all-new and bigger turboprop as early as next year. Other projects are taking shape in China and Germany.
The upgraded PW127 engine would reduce costs by staying in use longer between repair visits and reducing maintenance costs while offering incremental savings in fuel and emissions, the sources said, asking not to be identified.
