Honeywell TPE-331-10

The Do228 is equipped with the Honeywell TPE-331-10, a single-shaft engine known for its compact size, high power capabilities, immediate responsiveness, and short acceleration time.

The best-in-class performance of the Do228 has been significantly improved by the upgrade to a 5-blade, composite propeller in combination with the fuel-efficient TPE331-10 engine. Improved performance and enhanced operational capabilities are realized over the entire flight profile.

Characteristics

  • The propeller blades are 4 inches shorter, providing improved ground clearance. 

  • Shorter blades prevent the draw on surface debris during take-off, protecting intakes. 

  • The composite blade construction lightens load and ensures increased fuel efficiency. 

  • The increased number of lighter blades enable quicker accelerations, saving up to 20 seconds. 

  • More powerful blade rotations reduce stress on batteries and generators over time and extend their life cycles. 

  • Noise and vibration are reduced, enhancing the passenger and crew experience.
