Fig.1.2. The dispenser of cf5061gxjynkr type.
CF5061GXJYNKR dispenser consists mainly of chassis, pipeline system, pneumatic control system, hydraulic system, electrical system, etc. This type of dispenser allows large flow of aviation fuel to enter the aircraft fuel tank safely and quickly. It filters oil impurities, from the fuel, and accurately measure the amount of fuel.
The main characteristic of this dispenser is its total height is not exceeding 2 meters, which allows it process any size of the aircrafts without limitations. The product can at maximum speed perform small, medium and large sized aircraft underwing refueling using its two platform hose or a single reel hose.
Refueling - the fuel from the borehole passes the filters and metering, using hose reel or platform and goes into the aircraft fuel tank;
Recovery tank – during the refueling process, the fuel from the recovery tank will pass the filters and will be go to aircraft fuel tank, while the recovery tank will be emptied.
The values of main parameters and technical specification of CF5061GXJYNKR dispenser are given in the Table 1.2.

The third prototype of hydrant dispenser, is the vehicle of model 120 m3/h hydrant dispenser (Fig.1.3). Its functions and specification are also considered.
Fig.1.3. The dispenser of 120 m3/h capacity
So, the performances of the hydrant dispenser of 120 m3/h capacity are:
Fuelling performances: 2000 l/min (500 gpm) through the deck hose. 1000 l/min (250 gpm) through the 2’’ long hose EN1361-C HD type (U/W nozzle).
Filtration: one filter in total compliance with API/IP norm.
Mesuring system: one meter with adapted lighting for night operations : refuelling operations.
Regulation: primary regulation consists in hose end pressure control valve (HEPCV). Secondary one consists in line pressure control valve mounted on hydrant coupling.
The next prototype of hydrant dispenser, is the vehicle of model 120 HD01 - capacity of up to 4000 l / min (Fig.1.4). Its functions and specification are also considered.
