PAUNOVIC propellers: unmatched power, efficiency, and silence for air and sea.
The PAUNOVIC propeller is an advanced propulsion system characterized by a unique complex blade design that incorporates a tandem arrangement of primary and secondary blades. Each complex blade features a leading blade positioned above and a following blade below, connected at their tips with specialized blade connectors. This configuration not only increases thrust density but also enables fluid acceleration through optimized aerodynamic pathways, reducing rotational drag and improving overall efficiency.
The blade design allows for innovative fluid dynamics, where the interconnected blades create a controlled pressure difference around the complex blade and blade connectors. This design minimizes tip vortices and noise while generating additional lift, addressing two critical challenges in traditional propulsion: efficiency and noise reduction.
The PAUNOVIC propeller’s design further allows for custom blade configurations, such as straight, swept, and curved profiles, adaptable for both air and water applications. Through rigorous CFD simulations and experimental testing, the PAUNOVIC propeller has demonstrated higher thrust and lower noise levels compared to traditional multi-blade propellers, establishing itself as a versatile and highly efficient solution for diverse propulsion needs.
PAUNOVIC propellers bring a new standard to water propulsion, providing powerful thrust with dramatically reduced noise—essential for stealth and environmental compliance in marine applications. The unique complex blade design enhances efficiency, minimizing drag and fuel consumption, making it ideal for both commercial and defense vessels. By reducing cavitation and noise, PAUNOVIC propellers improve performance while promoting a quieter, more sustainable maritime experience.
Currently, the PAUNOVIC propeller technology remains in the experimental phase, showcasing impressive results in tests and simulations. However, we are able to offer small-scale custom production for interested parties who want to explore the advantages of this technology firsthand in water applications. This approach allows early adopters to leverage the unique efficiency, reduced noise, and enhanced thrust capabilities that PAUNOVIC propellers bring to marine propulsion.
This model showcases a 3-blade marine propeller with a 418 mm diameter, utilizing a complex blade design. The primary and secondary blades within each complex blade are set at angles of attack (AoA) of 40° and 45°, respectively, with blades connector angled at 20° AoA. An independently noise-tested smaller non-fully optimized 140 mm version of this propeller has demonstrated superior performance over the MIT-featured toroidal propeller, which was optimized by a leading CFD propeller optimization company.
