TurAerospace fuel systems are crucial for the efficient and safe operation of aircraft, encompassing a complex network of components designed to store, manage, and deliver fuel under varying conditions. These systems ensure optimal performance from takeoff to landing, playing a pivotal role in the aircraft's functionality.
A key element of these systems is the fuel pump, responsible for delivering fuel from the tanks to the engines, maintaining consistent flow regardless of altitude or pressure. Advanced systems also incorporate filtration mechanisms to remove contaminants, ensuring reliable engine performance and contributing to sustainability by minimizing fuel consumption and emissions.
Modern aerospace fuel systems are also integrated with advanced electronics and sensors. These components monitor fuel levels, flow rates, and pressure, allowing real-time adjustments to ensure optimal performance. This is crucial for maintaining the aircraft's balance and stability, enhancing both safety and efficiency.
At ANOVA ARGE Company, we focus on fuel system components and total system integration, ensuring seamless operation of all components to support aircraft needs.
The fuel booster pump is a critical component of the fuel system’s
distribution subsystem. It delivers the proper amount of clean fuel at the
correct pressure to the engines under all flight conditions. The cartridge-
type design allows for easy maintenance without draining the tank. It also
features a self-suction capability. Click here to check our brochure.
The non-return valve prevents fuel from flowing backward and helps maintain pressure within the fuel system.
Shut-off valves are used in helicopters to stop fuel flow in emergency
situations or to isolate parts of the fuel system for safety and maintenance
purposes
"Shut-off valves and crossfeed lines work together in helicopters to control
fuel routing between tanks and engines, provide redundancy in case of
failure, and enhance safety during emergencies such as engine fires."
A fuel pressure transducer is installed on each engine’s fuel feed line to monitor and measure the fuel’s gauge pressure. It transmits the pressure signal to the rotorcraft’s avionics system.
The Pressurized Fuel Refueling Subsystem enables efficient and controlled aircraft refueling via pressurized fuel transfer. In addition, the system provides a defueling capability, allowing safe transfer of fuel back to the ground fueling unit under maintenance or servicing conditions.
In case of a failure in the refueling/defueling system, the pressure inside the fuel tanks may rise until it reaches the structural limit. Exceeding this limit may result in structural damage to the aircraft’s surrounding structure. To mitigate this risk, a Pressure Relief Valve (PRV) is installed to relieve excess pressure and protect the structural integrity of the tank.
The Bleed Valve is used to drain the water accumulated at the bottom of the fuel tanks and collect fuel samples, ensuring the safe and efficient operation of the helicopter.
The Gravity Filler CAP (GFC) is a connection point that allows the helicopter’s fuel tanks to be manually filled using gravity. It is typically used as a backup or emergency refueling method when pressure refueling is not available.
Capacitive gauging probes are used to accurately indicate the fuel mass remaining in the aircraft’s tanks. They determine fuel level by measuring the dielectric constant of the fuel. The collected data is transmitted to the aircraft’s Fuel Control Unit (FCU), where it is processed to precisely calculate the remaining fuel quantity, ensuring safe flight operations and efficient fuel management.
The Low Level Sensor detects when the fuel level drops below a critical threshold. It sends a signal to the cockpit to alert the pilot and may also trigger automatic fuel transfer or system protection functions.
