In this episode, we analyze a CFD study on curved-tip propeller geometry for hovering drones, comparing it directly to a standard straight-blade propeller.
The paper uses computational fluid dynamics (CFD) to evaluate thrust, power consumption, efficiency, and flow structures for both propeller designs.
While the curved-tip propeller produces significantly higher thrust, it also requires more power, resulting in reduced flight endurance.
This video breaks down the aerodynamics behind those results, including:
• tip vortices and induced losses in propellers
• how curved tips function like winglets
• thrust vs efficiency trade-offs in hovering flight
• why higher thrust does not always mean better performance
• how CFD is used to evaluate drone propeller designs
🧠 Key takeaway
Curved-tip propellers don’t make drones more efficient — they reallocate energy from endurance to lift
