Key Technologies of Aviation Fuel Systems and Integrated Equipment Solutions

As a company specializing in fuel transfer equipment manufacturing, we deeply understand the complexity and high-standard requirements of aviation fuel systems. This article will analyze three core elements - aviation fuel composition, aircraft fuel tank design, and fuel system architecture - while focusing on introducing professional aviation refueling equipment solutions to provide comprehensive technical support for aviation industry clients.

Aviation Fuel Characteristics and Specialized Refueling Equipment

The unique properties of aviation fuel demand refueling equipment with exceptional safety and precision. Current mainstream aviation fuels include Jet A, Jet A-1, and Jet B, which feature high flash points, low freezing points, and excellent thermal stability. Jet A-1, the most widely used aviation turbine fuel globally, has a flash point ≥38°C and freezing point ≤-47°C, requiring all fuel-contacting equipment materials to possess outstanding chemical corrosion resistance.

To meet these specialized requirements, we have developed a series of aviation-specific refueling nozzles made from aerospace-grade aluminum alloy or stainless steel with special surface treatments to ensure compatibility with various aviation fuels. Our products have obtained API 607 fireproof certification and ATEX explosion-proof certification, meeting the most stringent aviation safety standards. Particularly, our high-flow aviation refueling nozzle series can achieve flow rates exceeding 1000L/min, specifically designed for rapid refueling of large commercial aircraft and already in use at multiple international airports.

With Sustainable Aviation Fuel (SAF) becoming an industry focus, our equipment is fully compatible with various SAF blends. In 2023, we participated in developing the world's first "SAF Refueling Equipment Technical Specifications," providing industry solutions for the special requirements of biofuels on sealing materials.

Aircraft Fuel Tank Structures and Over-Wing Refueling Technology

Modern aircraft fuel tank systems feature complex designs, primarily including integral wing tanks, center tanks, and auxiliary tanks. Different tank locations and structures determine various refueling methods. Modern airliners like the Boeing 787 typically use pressure refueling systems through single-point refueling ports under the fuselage, while general aviation aircraft commonly employ over-wing refueling directly through fuel ports on the wing surface.

For over-wing refueling requirements, we developed the Over-Wing series aviation refueling nozzles with these outstanding features:

Ergonomic design for labor-saving operation, allowing single-person refueling
Integrated anti-static system ensuring safe refueling
Automatic shut-off function preventing spill accidents
Optional digital Flow meter with ±0.5% accuracy

Our over-wing refueling equipment has obtained dual certification from FAA and EASA, serving over 200 general aviation airports worldwide. Particularly for helicopters and other special aircraft, we developed lightweight, drip-proof specialized nozzles solving safety challenges in rotor-down refueling.

Aircraft Fuel Systems and Ground Refueling Equipment Integration Solutions

A complete aircraft fuel system includes multiple subsystems for storage, transfer, supply, and monitoring. As ground support equipment providers, we offer comprehensive ground refueling solutions that seamlessly integrate with onboard fuel systems:

High-flow pressure refueling systems: For commercial airliners with flow rates up to 4000L/min, featuring intelligent control systems that automatically identify aircraft models and match optimal refueling parameters. The system integrates multiple protection devices against overpressure, static electricity, and overflow.

Aviation fuel filtration systems: Utilizing three-stage filtration with precision up to 3 microns, ensuring fuel purity meets ASTM D1655 standards. The system includes differential pressure alarms and automatic drainage, widely used in airport fuel storage systems.

Mobile aviation refuelers: Integrating pump units, metering systems, filtration systems, and control terminals, suitable for military airports and remote areas. Our latest models adopt new energy power to reduce carbon emissions, aligning with aviation industry environmental trends.

Intelligent refueling management systems: Using RFID technology for automatic aircraft identification, interfacing with airport fuel management systems for complete refueling process traceability. The system generates electronic refueling records meeting civil aviation regulatory requirements.

Industry Hotspot Technologies and Innovative Products

Considering current trends in aviation fuel technology, we focus on developing these innovative products:

Carbon-neutral refueling equipment series: Featuring lightweight designs to reduce energy consumption from equipment weight, using recycled materials to lower lifecycle carbon footprint by 40%.

Smart anti-misoperation refueling nozzles: Integrating sensors and AI chips to automatically identify aircraft refueling port types and prevent errors. Mechanical interlocks prevent refueling when mismatches are detected.

Multi-purpose aviation fuel service stations: Supporting both conventional aviation fuel and SAF refueling, automatically identifying fuel types and adjusting parameters. This solution is particularly suitable for airports undergoing energy transitions.

UAV autonomous refueling systems: Targeting the emerging drone logistics market, developing fully automatic refueling robotic arm systems for unattended operation, with ±0.1% accuracy and capability to refuel 20 medium-sized drones per hour.

Looking ahead, our technology roadmap includes:

Research on hydrogen fuel aviation refueling equipment
Blockchain-based aviation fuel full-process traceability systems
AR-assisted refueling operation guidance systems
