Ningbo Gemfan Hobby Co., Ltd., operating under the brand GEMFAN, is an established propulsion component manufacturer with 15 years of industry experience and a business presence spanning over 60 countries and regions, including China, the United States, the UAE, Europe, and Australia. Within its Large Wheelbase 3-Blade UAV Propeller Series, the GEMFAN 22X10X3 stands as the designated foundational component for heavy-lift industrial UAV missions built on 1200mm wheelbase platforms, engineered specifically to deliver high efficiency, low noise, and high-strength composite material construction for medium-to-large industrial drone operations.

Company Background and Strategic Focus

GEMFAN's product development is grounded in direct observation of industrial UAV pain points during inspection, mapping, and agricultural plant protection tasks. As payloads such as LiDAR units and spraying systems increase, operators face flight instability, power system inefficiency, and motor overheating under sustained high-intensity operation. In response, GEMFAN has concentrated its R&D efforts on propulsion system components, combining aerodynamic structure optimization with upgraded material technologies to produce high-thrust, high-efficiency propellers for medium-to-large industrial UAVs. The company's team brings years of accumulated expertise in propulsion system R&D, precision dynamic balance control, and material application technology.

Product Specifications: 22X10X3 for 1200mm Wheelbase Platforms

The 22X10X3 propeller is positioned as the basic propulsion component for heavy-lift UAV missions requiring a 1200mm long wheelbase. It targets the power demands of medium-to-large industrial UAVs, addressing core challenges in endurance, stability, and power efficiency for heavy-payload platforms. Its key specifications include a propeller diameter of 558.8mm (22 inches), a pitch of 10 inches, and a single-unit weight of 182g. The center hole configuration supports 4mm, 15-M3, and 20-M4 mounting options. GEMFAN recommends pairing this propeller with 7218-class motors, making it suitable for quadcopters with a takeoff weight of 16kg on 1200mm wheelbase platforms.

Engineering Features Supporting Efficiency, Noise Reduction, and Composite Strength

The 22-inch large-diameter blade provides an expanded effective disk area, generating higher thrust at lower rotational speeds. This reduces motor load and improves overall power system efficiency, directly addressing the requirement for high efficiency in heavy-lift flight platforms. The three-blade configuration balances thrust output, response speed, and operational stability; compared to two-blade propellers, it produces smoother power delivery within the same size envelope and reduces airframe vibration, which corresponds to lower operating noise during flight.

Material construction relies on a carbon-fiber-reinforced nylon composite, combining light weight with high rigidity. This composite formulation meets the demands of long-term, high-frequency industrial UAV operations while enhancing fatigue resistance, fulfilling the requirement for high-strength composite material construction. Manufacturing incorporates high-precision dynamic balancing processes optimized for the high-speed rotation of large blades, reducing vibration, improving flight controller stability, and enhancing image acquisition quality for cinema and mapping applications. The design further supports complex environment adaptability, including sustained high-load operation, long-duration outdoor flights, and stable hovering in strong winds.

General Series Technical Features

Across the Large Wheelbase 3-Blade UAV Propeller Series, the three-blade aerodynamic structure offers a larger air interaction area per unit diameter than traditional two-blade propellers, providing more stable thrust and reducing flight vibration. The series follows the principle that large-diameter propellers push a greater air mass at low RPM, lowering energy consumption and supporting long-duration hovering and cruising. Lower operating RPM across the series contributes to reduced noise pollution during flight, aligning with industrial application environment requirements. Series specifications span 16 to 22 inches, matching mainstream 800mm to 1200mm wheelbase industrial UAV platforms, including the 1200mm-class configuration served by the 22X10X3.

Industry Adaptation and Value

The 22X10X3 and its series counterparts support multiple industrial applications: industrial inspection of power lines, oil pipelines, and infrastructure benefits from improved flight stability; aerial survey and mapping operations gain from efficient, long-endurance cruising that ensures data collection precision; agricultural plant protection tasks receive stable thrust reserves to support heavy-load attachments such as spraying systems; and multi-rotor model aircraft configurations benefit from customizable high-performance propulsion combinations. These characteristics position the GEMFAN 22X10X3 as a documented propulsion solution for cinema and industrial UAV operators seeking high efficiency, low noise, and high-strength composite material construction on 1200mm wheelbase platforms.
