A cross-flow fan is a centrifugal fan in which the air flows straight through the fan instead of at a right angle. The rotor of a cross-flow fan is covered to create a pressure differential. A cross-flow fan has two walls outside the impeller and a thick vortex wall inside. The radial gap decreases in the direction of the impeller rotation.
Subsequent research in the US focused on the use of a crossflow fan inset into the wing upper trailing edge, as the primary driver for boundary layer control and jet flap propulsion. [ 3 ] More recently, several unmanned aerial vehicle (UAV) projects have explored the potential of distributed propulsion to offer noise abatement, fuel efficiency ...
The propulsive wing is a patented [1] UAV (unmanned aerial vehicle) design concept developed in the 2000s with extremely high lift and internal volume. The propulsive wing could be used to develop a new class of aircraft based on an embedded, distributed cross-flow fan propulsion system within a thick wing.

FanWing cross-section showing airflow. The FanWing is a type of aircraft rotor wing in which a horizontal-axis cross-flow fan is used in close conjunction with a fixed wing. The fan forces airflow over the fixed surface to provide both lift and forward thrust.
A centrifugal fan is a mechanical device for moving air or other gases in a direction at an angle to the incoming fluid. Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink; such a fan is also called a blower, blower fan, or squirrel-cage fan (because it looks like a hamster wheel).
