I. Industry Background
The "14th Five-Year Plan for Green Development of Civil Aviation" and the "Action Plan for the Construction of Four-Type Airports in China's Civil Aviation" have established the strategic goal of perfecting a green, low-carbon, and circular development system for China's civil aviation by 2035. Against this backdrop, airlines, airports, and equipment manufacturers are actively responding and are committed to exploring and building green and low-carbon models for civil aviation.
II. Industry Demand
With the promotion of green and smart construction concepts, airport ground support equipment has increased significantly. To meet the layout requirements of aircraft stand equipment, the design of aircraft ground static power supplies should consider increasing the power supply coverage, especially in old airport renovation projects, where the equipment location layout has many factors to consider, and the power supply is far from the aircraft, usually more than 30 meters away.
The challenges of traditional solutions during implementation
1. Underground well-type power supply - dependent on civil engineering
While the underground power supply solution demonstrates advantages in long-distance power supply, it is not suitable for the renovation of old airports without interrupting operations due to its dependence on civil engineering. It also faces many challenges in practical applications due to limitations such as long construction periods and high costs.
2. Ground-based cable reel power supply - distance limited
While the ground cable reel power supply solution saves on civil engineering costs, it is limited to short distances. Long cables need to be manually dragged to the machine head, increasing the operational burden and manpower requirements. Therefore, it applies to distances not exceeding 30 meters.
III. Solutions
Ainuo Instruments has been deeply involved in the aircraft ground power supply industry for many years. For aircraft positions with a power supply distance of more than 30 meters, it has innovatively launched the motorized all-in-one aircraft power supply AN17MC(F), which combines economy and manpower optimization to provide electric mobile reel power supply solutions for civil aviation airports.
The motorized all-in-one aircraft power supply is electrically assisted in its movement and automatically releases the cable synchronously. It moves with the vehicle, eliminating the need for manual dragging and easily covering a power supply distance of 45 meters. The operation is simple; a single person can control it, reducing physical strain.
IV. Application Cases
Application of Contact Stands at Wuhan Tianhe Airport
As a major aviation hub in Central China, Wuhan Tianhe International Airport has seen continuous growth in passenger throughput and a surge in flight takeoffs and landings in recent years, placing higher demands on ground support efficiency and green operation levels. Its near-gate renovation and upgrade project faces the practical challenge of adapting to traditional power supply solutions.
Based on this, Wuhan Tianhe Airport introduced Aino Instruments' electric mobile reel products to build an efficient and safe long-distance power supply system.
Operating Procedure: During operation, the operator uses an integrated joystick to move the reel towards the aircraft. The cable is automatically and synchronously released during this process. Thanks to the equipment's automatic speed-matching algorithm, the cable release speed precisely matches the reel's movement speed, preventing damage caused by cable pulling and avoiding ground friction caused by cable accumulation. Once the reel reaches the aircraft, the operator inserts the aviation connector into the aircraft's power supply interface, completing the power-on operation. After power is supplied, the joystick is reversed, and the cable automatically retracts. The entire process can be completed independently by a single person without additional human assistance.
Environmental adaptability: Wuhan experiences high temperatures in summer and low temperatures in winter with occasional rainfall. The electric mobile conveyor belt, with its 7-4Gc56- level heat resistance, can withstand dust and dust intrusion and can operate stably within a temperature range of -40℃ to +60℃, fully adapting to local climate conditions and ensuring uninterrupted power supply throughout the year.
Application Results: After its implementation at Wuhan Tianhe Airport, this solution significantly improved the power supply efficiency near aircraft stands, reducing the single power supply operation time by approximately 30% compared to traditional solutions and lowering labor costs by over 50%. Simultaneously, because the cable has no sliding friction with the ground, its service life is extended by 2-3 times, indirectly reducing equipment maintenance costs. Furthermore, the electric-assisted design of the electric mobile drum avoids carbon emissions from fuel-powered equipment, highly aligning with the airport's green development concept and providing strong support for the construction of a "four-type airport" (airport with environmental protection, energy conservation, and environmental protection ).
V. Product Introduction
The motorized all-in-one aircraft power supply AN17MC(F) can solve the problem of long-distance power supply for fixed aircraft ground power sources, making it the best solution for fixed ground power transmission in near-gate, remote-gate, and hangar scenarios. It can transmit intermediate frequency electricity, EF signals, and control signals. Power start-up, stopping, and cable winding/unwinding can be operated using aviation connectors. The winding/ unwinding cart has an integrated joystick, and the movement of the reel cart and the winding/unwinding of the power supply cable are all controlled via the joystick.
Features
It meets the needs of long-distance power supply and can accommodate 45-meter cables.
The interlock function prevents the scooter from moving when the power is turned on or when the plug is inserted into the aircraft.
Overload protection function: The system can stop the circuit promptly when the cable is under stress, protecting the cable.
Limit protection function: automatically stops when the cable is fully extended or fully retracted.
The entire process, from opening to closing, is electrically assisted, saving time and effort.
Throughout the entire process, there is no slippage or friction between the cable and the ground, extending the cable's service life.
With an IP55 protection rating and a temperature range of -40℃ to +60℃, it meets the operational requirements of airports in various regions.
An automatic speed matching algorithm ensures that the cable is not pulled or piled up.
Excellent human-machine interface design, charging reminders, and driving reminders;
Comprehensive safety features include: stop if the lever comes detached, power off if pushed up, and an emergency stop button.
With its ultra-long battery life, a single charge can last for one month under normal operating conditions.
