Abstract

The invention discloses a preselected refueling control system and a refueling method. It is connected with the second oil tank, the first and second oil tanks are connected through the oil tank connecting pipe, the refueling joint communicates with the first fuel tank through the refueling control valve and the refueling pipe, and the oil level signal device includes the first oil level signal device and the second oil level signal device. The oil level annunciator, the first oil level annunciator and the second oil level annunciator are connected through a control switch and are connected with the refueling control valve. The oil level annunciator, the full oil signal lamp and the refueling control valve are all powered by the power supply. By adopting the refueling control system and refueling method of the present invention, two connected fuel tanks can be refueled through one refueling control valve, and different amounts of fuel can be selected to meet the control accuracy of different refueling flow conditions. It has simple structure and convenient operation. Suitable for promotional use.

Description

A preselection fueling control system and fueling method technical field What the present invention relates to is fuel system automatic refueling technical field, specifically a kind of preselected refueling control system and refueling method. Background technique

[0002] An aircraft usually contains multiple fuel tanks, and when refueling, a single branch is usually refueled separately. In the design of the refueling system, Refueling with pre-selected oil volume in two fuel tanks generally requires two fueling control valves and two oil level signals, and each fuel tank oil level signal Control the fueling control valve of the fuel tank separately. Use a refill control valve to fill the two tanks with preselected quantities of oil, at different Under the oil flow, the oil level difference between the two oil tanks is different. Use the oil level signal in the first oil tank or the second oil tank to control, There will be a large amount of fuel error, and it is...
