Specialized Propeller Design and Consultation
We collaborate closely with you to understand the specifics of your UAV platform and its applications, including altitude requirements, payload capacities, and any specialized needs such as noise reduction. From this information,we generate a detailed quote and project timeline.
The initial phase of our design process involves selecting an appropriate motor and electronic speed controller (ESC) tailored to your requirements.We then conduct both computational and dynamic wind tunnel tests using various configurations of existing commercial products to gather data and inform our next steps.
We utilize cutting-edge 3D modeling techniques to create your custom design, ensuring that the propeller can endure significant forces from the engine, high RPMs, and increasing flight speeds. Our proprietary software, grounded in Blade Element Momentum and Vortex theories, delivers precise propeller flight characteristics, which are further validated through advanced simulation methods, including Computational Fluid Dynamics (CFD) analyses and airflow measurements that continuously enhance our mathematical models.

Exceptional Tooling,Prototyping,and Manufacturing Quality
We meticulously design the structure and molding of the prototype, considering factors such as layering, core elements, and inserts, to create an initial product that can be tested on your UAV platform for further data collection and refinement. Once the design is finalized, we collaborate with you to confirm the final setup, scaling requirements, and any constraints for mass production.
All drone propellers undergo rigorous weight testing,subjected to forces considerably exceeding those expected during flight,ensuring robust construction and secure layer bonding,providing you with complete confidence. Each propeller is balanced both horizontally and vertically at three critical stages: during manufacturing, quality control, and prior to shipping. Additional testing can be conducted to certify your platform, including compliance with FAR part 35 airworthiness standards. Collaborations with certified EASA and FAA aviation centers allow for endurance testing, saltwater resistance assessments, speed camera evaluations, and further strength and wind tunnel testing.
