tractor propeller
An airscrew or propeller located in front of the engine, which pulls the airplane. It is unlike the “pusher propeller,” which is located in the rear of the wing and pushes the airplane. The tractor propeller “pulls” the airplane through the air, and the thrust bearings in the engine are designed for thrust loads in that direction. Most modern aircraft use this type of propeller because of the unrestricted flow of airflow into the propellers. See also pusher propeller.

Europe's principal achievement in high-speed rotary-wing flight is the 5.2-tonne Airbus Helicopters X3 compound helicopter, which is based on the EC155, but has short wings, mounting tractor propellers. These are driven by the main engines and produce differential thrust to eliminate the need for a tail rotor.
Caption: Based on the EC155, the 430 km/hr Airbus Helicopters X3 adds short wings and tractor propellers, shaft-driven from the existing engines to provide both thrust and torque, allowing deletion of the tail rotor.
