Refueling equipment, and method for refueling an aircraft using said equipment

The invention relates to equipment for refueling an aircraft, including a pipe (40) provided with means (42) for connecting onto an intake port (301) of the fuel tank of the aircraft (400) and, at or in the vicinity of the connection means (42), means (501) for determining the value of at least one parameter representative of a flow (E) of fuel passing through the connection means. Said equipment further includes at least one receiver onboard the refueling equipment (1), means (503, 504) for transmitting, to the receiver, a signal (Si(P)) representative of a parameter value predetermined by determination means (501) and an electronic unit capable of receiving, from the receiver, a signal representative of the parameter and of driving at least one flow control and monitoring device in accordance with the signal received from the receiver. The refueling method includes the steps of during a refueling operation, determining the value of at least one parameter representative of the flow (E) at or in the vicinity of the connection means (42), transmitting, to at least one receiver onboard the refueling apparatus, a signal (Si(P)) representative of a parameter value predetermined during the previous step, and automatically driving, in accordance with the signal received by the receiver, a flow control and monitoring device.

Parallel balanced filling method for high-capacity semi-management surface tension storage tank

ActiveCN106762224AReal-time display of total filling amountReal-time monitoring of parallel balanceLiquid handling installationsCosmonautic propulsion system apparatusEngineeringHelium
A parallel balanced filling method for a high-capacity semi-management surface tension storage tank comprises steps as follows: (1) a satellite propellant filling pipeline is connected, and the leakage rate of a filling pipeline system is ensured to meet the requirements; (2) two parallel storage tanks are simultaneously filled with helium or release helium for replacement until sampled gas is tested to be qualified; (3) the propellant filling pipeline and pipelines at the downstream of the parallel storage tanks are vacuumized; (4) valve ports of filling and drainage valves of the parallel storage tanks are filled with the propellant; (5) the parallel storage tanks are simultaneously and stably filled until 90% or above of the rated filling quantity is reached; (6) refilling is performed on the parallel storage tanks until the filling quantity of each storage tank meets the task requirement; (7) air cushions are added to the storage tanks until required air cushion pressure is reached. By means of the method, parallel balanced filling of the high-capacity semi-management surface tension storage tank can be realized, time for filling the parallel storage tanks with the propellant is shortened, and the reliability and the safety of the satellite filling process are guaranteed.
