Prop Duct for future VTOL hoverbike project.

The design can be scaled up or down to suit specific requirements.\nAccording to NASA, implementing a similar duct system in a ducted fan VTOL aircraft can lead to increased lift. Observers have pointed out that the curved lip on the duct creates lift, akin to a wing. However, its functionality remains uncertain at this stage. Nevertheless, it has a futuristic aesthetic. Those interested should consider researching the Hiller VZ-1 for inspiration.\nThis design, specifically designed for a hover bike prototype, features two ducts arranged in tandem. Its success is heavily reliant on robust structural supports, particularly in regions with limited material integrity. During initial tests without adequate reinforcement, fragile structures have been known to compromise the integrity of prints. By adding an increased number of rib supports, manufacturers can guarantee a secure structure that accommodates minimal clearances – up to 2mm – while interacting closely with rotating parts.\nThough it may draw from Hiller's VZ-1 design, this specific concept does not intend to achieve exact scale. Nonetheless, it showcases versatility by also potentially benefiting hovercraft applications.
