Illustration of slats and flaps of an airplane and corresponding lift and drag Effects of the boundary layer on the pressure distribution and the lift characteristics of single airfoils .
While satisfying this pitching moment constraint does constrain the airfoil performance, making this airfoil have overall higher drag as compared to airfoils with similar lift, I believe it is worth it, as stabilizing a flying wing can be extremely challenging.
Features and benefits • Patented airfoil system includes six airfoils and cuffed winglets that maximize performance and efficiency • Industrial-grade motor and gearbox offers efficient, reliable and durable operation • Weighs less than 145 lb (65.8 kg) allowing for easy positioning and installation • Factory-wired motor and controller cable with optional power cord plug • Perfect for spaces up to 70 x 70-ft (21.3 x 21.3-m) and ceilings as low as 14-ft (4.3-m) • Year-round energy savings, up to 10° cooling effect in hot weather and 1% energy savings per foot of ceiling height in cold weather The unique aerodynamic design enhances both energy efficiency and airflow by eliminating vortex formation at the airfoil tips.
The fan will be installed so that the airfoils are at least 10 ft (3.05 m) above the floor.

As an example, some spaces are female just, or don't allow add-ons such as pets or airfoils (which take a great deal of bandwidth to render and reduce the area).
