Abstract:
1. An aircraft refuelling equipment for an aircraft, the equipment comprising: a pipework comprising a fuel supply line connected to a plurality of tank supply lines; fuel tanks connected to tank supply lines of the pipework and adapted to be refuelled through the fuel supply line); first valves arranged in said pipework and adapted to allow each fuel tank to be disconnected from the fuel supply line; at least one captor allowing, for each of said first valves, a first valve flow parameter to be estimated, said at least one captor being arranged within the pipework for providing at least one signal indicative of a pressure or a flow rate, said at least one captor comprising at least one pressure captor for sensing a pressure within the pipework and for providing at least one signal indicative of a pressure; wherein each first valve comprises a valve body with a plurality of adjustable positions between a full open position and a closed position, wherein the equipment further comprises: at least one actuator associated with each of said first valves in a respective actuator-first valve assembly and allowing adjustment of an opening of the associated first valve at a defined position of the valve body chosen among the full open position, the closed position and the plurality of adjustable positions therebetween; an electronic control unit (ECU) connected to the respective actuator-first valve assemblies,the electronic control unit comprising: a receiving module for receiving position data from said first valves and for estimating the respective first valve flow parameters, using the pressure data and the position data, and a control module adapted to regulate the opening of the first valves, using respective first valve flow parameter data.
