Radial Windbreak Layout for Stable VTOL Take-Off and Landing

The patent divides the landing area into multiple sectors using three or more windbreak walls that extend radially from a central axis. Each wall creates a separate sector, allowing wind to be blocked effectively while preventing the formation of complicated vortices that would occur with a fully enclosed four-wall structure. The radial arrangement ensures that wind flows are managed in a controlled manner without creating destabilizing secondary flows.

The patent employs an asymmetric radial configuration where three or more walls extend from a central axis at different angles, creating unequal sector divisions. This asymmetric arrangement prevents the symmetric vortex formation that occurs with traditional four-sided enclosures, as the wind flow paths are intentionally made unequal to disrupt vortex development while maintaining effective wind protection.

Instead of enclosing the landing area with walls on all four sides (traditional approach), the patent inverts the approach by using three or more radial walls that extend from a central axis outward, creating open sectors rather than a closed enclosure. This inverted radial configuration effectively blocks destabilizing wind flows from multiple directions while maintaining structural simplicity through the shared central support structure.

The patent merges multiple wall structures into a unified radial system where three or more windbreak walls share a common central axis and support structure. This consolidation reduces overall structural complexity compared to four separate enclosed walls, as the radial walls can be supported by a central column or hub, efficiently using shared structural elements to achieve wind protection across multiple sectors.
