CENTRALIZED AIRCRAFT REFUELING SYSTEM IS A TIME OPTIMIZATION FOR AIRCRAFT REFUELING
In recent years, the civil aeronautics have widely used the pressure refueling systems, in which the fuel is fed from the feed-tanks by pumps through pipelines directly to the aircraft tanks.
- Practically unlimited performance and reduced aircraft fueling time;
- Reducing labor intensity of the production process of intra-aerodrome fuel pumping and reducing maintenance personnel;
- Average 4 times decrease in the cost of fuel delivery from the fuel depot to the aircraft tanks;
- Prevention of fuel contamination by mechanical impurities and water contamination during transportation from tanks to aircraft owing to tightness;
- Increase of fire safety during refueling due to the lack of tanks with fuel in close vicinity to the aircraft.
- Expenses for the capital construction of the CAFS systems are relatively small and fast-payback due to reducing operating costs.
Airports use three types of CAFS systems, differing in equipment capability and quantity of fuel pumped:
- Dismountable simplified systems in airports are of the IV and V classes;
- Average performance systems in airports are of the II and III classes;
- High-performance automated systems in airports are of the I class.
- An aircraft is installed on an apron or a parking area in accordance with the currently available striping and fixed from moving by the stop blocks after the engine has been stopped;
- Sediment is discharged from the aircraft tanks and sampling for presence of mechanical impurities and water is carried out according to the current regulations;
- A mobile refueling unit is put on the handbrake in a space designated to it, next to a hydrant (connecting column), and fixed from moving by the stop blocks;
- Inlet hose of the mobile refueling unit is grounded and connected to the hydrant; discharge hoses are unfolded and connected to the aircraft; fueling nozzles are opened and at the same time electrical connection (metallization) of the refueling unit with the aircraft is provided using a cable;
- A required flow and pressure refueling mode as well as a dose of an additive deicing fluid are set on the refueling unit;
- Fuel sediment from filters and refueling nozzles (valve) is discharged and checked.
