A Balanced Fuel Delivery System for Symmetrical Fuel Tanks

Abstract

A balance oil transportation system of symmetric oil tanks comprises the left wing oil tank, the right wing oil tank, an oil transportation selection switch, a fuel control box, an oil transportation selection valve and an oil transportation pipeline. A left oil quantity sensor is arranged in the left wing oil tank, and a right oil quantity sensor is arranged in the right wing oil tank; and the left wing oil tank is connected with the right wing oil tank through the oil transportation pipeline, and an oil transportation selection valve is arranged on the oil transportation pipeline. The oil transportation selection valve is connected with a fuel oil control box and an engine; and the left oil quantity sensor, the right oil quantity sensor and the fuel oil control box are connected, and meanwhile, the oil transportation selection switch is connected with the oil transportation selection valve. The electric control oil transportation selection valve is combined with a manual control oil transportation selection switch so as to precisely achieve alternating oil transportation of the left wing oil tank and the right wing oil tank, and the phenomenon that in the oil transportation process of the symmetric oil tanks, unbalanced oil transportation easily happens is avoided. The stability and manoeuvrability of an airplane are effectively improved, and the service life of the airplane is prolonged.

Description

Technical field [0001] The invention relates to the technical field of aviation machinery control, in particular to a symmetrical fuel tank balanced fuel delivery system. Background technique [0002] The fuel tanks on the aircraft are symmetrically distributed. However, due to differences in fuel pump performance and aircraft maneuvers during flight, symmetrical fuel tanks are prone to uneven fuel delivery during the fuel delivery process, which will affect the stability of the aircraft and even cause the aircraft to lose control. Harm to aircraft flight, and uneven fuel delivery can easily damage the fuel components of the aircraft, which shortens the service life of the aircraft to a certain extent. Therefore, how to achieve the balanced oil delivery of the symmetrical oil tank and the accurate oil volume has become a technical problem to be solved urgently by those skilled in the art. Summary of the invention [0003] The technical problem solved by the present invention is t...

[0002] The fuel tanks on the aircraft are distributed symmetrically. However, due to the performance difference of the fuel pump and the influence of aircraft maneuvers during flight, the symmetrical fuel tanks are prone to uneven fuel delivery during the fuel delivery process, which in turn affects the aircraft's handling characteristics and even causes the aircraft to lose control. It is harmful to the flight of the aircraft, and the unbalanced fuel delivery is easy to damage the fuel components of the aircraft, which shortens the service life of the aircraft to a certain extent
