AFX TD Downwash
Taming Downwash

Aerofex has demonstrated its ducted-fan/ejector technology can tame the downwash of  VTOL aircraft.

The exposed blades of helicopters and multicopters generate significant tip-vortices and swirl. With the Aerofex tech the ejectors remove the swirl while the duct eliminates the vortices and expands the flow, reducing its energy.

Why does this matter?

When laying down retardant or spraying crops the characteristics of the downwash is paramount. Turbulence generated by conventional aircraft creates significant drift in these applications. While spraying is a necessary and effective tool for food production, the environmental impacts of drift can and should be mitigated. In manned applications, the turbulent downwash can cause brownouts that risk injury to personnel and damage to aircraft.
