Propellers are a critical component in myriad applications, particularly in aeronautical and marine environments. The design of a propeller impacts immensely the performance of the device it propels, the device's energy efficiency, and even the sound the device emits. However, conventional propeller designs have largely remained unchanged, with the structures remaining open, potentially affecting their performance, especially under high-stress operations. Current propeller designs face issues with stiffness and noise pollution. A less stiff propeller could distort under pressure, affecting the efficiency and reliability of the device. Noise caused by propellers, especially in marine environments, can disturb aquatic life and contribute to noise pollution. Thus, the need to upgrade propeller design to address these issues is imperative.
Technology Description
This innovative propeller is designed with a hub supporting multiple elongated elements. The novelty lies in the tips of these elements curving to contact with one another to form a closed structure. This design encloses the huge open space usually seen in conventional propellers, increasing the stiffness of the entire propeller and providing enhanced strength. The configuration of the propeller also reduces the noise that these mechanical devices usually generate, translating to a reduced acoustic signature. This technology is differentiated by these two innovative aspects: increased stiffness and reduced acoustic signature, unlike conventional propeller designs whose open structure both for aeronautical and marine environments makes them less rigid and noisier. This propeller design offers a unique adaptation that makes the propeller tougher, quieter, and more effective.
Benefits
- Increased stiffness provides better performance
- Lower acoustic signature reduces noise pollution
- New design could lead to increased energy efficiency
