RAYI Propeller Facilitates Breakthrough in Hydrogen-Powered VTOL UAV Technology

In a significant milestone for sustainable aviation, the LY-2300H—the world’s first 23kg-class hydrogen-powered vertical take-off and landing (VTOL) unmanned aerial vehicle—has successfully completed its maiden flight. This achievement underscores major advancements in small-scale hydrogen-composite VTOL drone technology, with the RAYI propeller playing a critical role as the exclusive propeller system for vertical lift.

Equipped with a 2kW hydrogen fuel cell system, the LY-2300H boasts a wingspan of 3.2 meters, a maximum takeoff weight of 23kg, and a payload capacity of 3kg. Its remarkable endurance of 4-6 hours sets a new benchmark for eco-friendly UAV operations.

Advanced Propeller Technology for Superior Performance

The VTOL aircraft relies on the RAYI 24x7.8-inch carbon fiber propeller, a high-efficiency, matte-finish monolithic propeller designed for heavy-duty applications. Key features of this advanced propeller include:

Maximum thrust: ≤9,000g
Weight: 58g
Safe operating RPM: 5,200 rpm
Operating temperature range: -40°C to +60°C

Engineered with proprietary high-temperature molding and bio-inspired airfoil design, the carbon fiber propeller delivers a 7-10% improvement in efficiency and a 40% enhancement in structural strength. These innovations ensure optimal performance under extreme conditions, making the propeller ideal for next-generation UAV platforms.

Engineering Excellence: Design and Validation

RAYI’s propeller development process integrates rigorous simulation and layered composite design. Computational fluid dynamics (CFD) analysis and chord-wise layup optimization ensure that the propeller achieves an ideal balance of durability and aerodynamic efficiency.

Future-Oriented Propeller Solutions

As a leading brand in high-performance propeller systems, RAYI continues to drive innovation in UAV safety and efficiency. The company recently announced its new 73x25 carbon fiber propeller, optimized for heavy-lift logistics drones and eVTOL platforms. With a strong focus on R&D and customization, RAYI remains committed to supporting the global aviation industry with reliable, cutting-edge propeller solutions.

This successful flight demonstrates the pivotal role of specialized propeller technology in enabling sustainable aviation breakthroughs. For more updates on advanced propeller systems and industry applications, stay tuned to RAYI’s latest developments.
