prop wash

Blade-generated airflow blast

Prop wash is the turbulent air pushed backward by a spinning propeller, whether on an aircraft or boat.

Pilots and ground crews avoid standing behind running propellers because the blast can knock a person down.

On water, prop wash is the churning wake directly behind an outboard motor.

The term also serves as a prank—sending a new recruit to fetch "a bucket of prop wash" from the supply room.
