HOVERCRAFT

Learn about aerodynamic and hydrodynamic Air Cushion Vehicles with this easy hovercraft activity!  

 

Hovercrafts create vents or currents of slow-moving, low-pressure air that are pushed downward against the surface below the hovercraft. Modern ACVs often have propellers on top that create the air currents. 


These currents are pushed beneath the vehicle with the use of fans. Surrounding the base of the ACV is a flexible skirt, also called the curtain, which traps the air currents, keeping them underneath the hovercraft. 


The trapped air currents can create an air cushion on any smooth surface, land or water! Since a hovercraft can travel upon the surface of water, it is also called an amphibious vehicle. - Sciencebuddies.org
