Fuel oil measuring system comprehensively utilizing large flight attitude change

Abstract

The invention provides a fuel oil measuring system capable of comprehensively utilizing large flight attitude change. The fuel oil measuring system comprises a float type fuel oil measuring sensor (1), an oil quantity data processing system (2), a flight attitude acquisition system (3) and a comprehensive display system (4), the flight attitude acquisition system (3) acquires flight pitch and rollangle changes in due time, angle values of the flight pitch and roll angle changes are transmitted to the fuel quantity data processing system (2), and the fuel quantity data processing system (2) comprehensively utilizes attitude angle change values and numerical values measured by the float type fuel measuring sensor (1) to calculate fuel quantity and transmits results to the comprehensive display system (4) to be displayed. The system can still keep a certain measurement precision when an airplane does a large maneuvering action, and the measurement precision of the float-type fuel oil measuring system is effectively improved.

Description

technical field [0001] The invention belongs to the field of aviation control, in particular to a fuel oil measurement system which comprehensively utilizes large flight attitude changes. Background technique [0002] The fuel in the wing fuel tank of the aircraft is transported to the consumption fuel tank through the oil delivery pipeline, and the fuel in the consumption fuel tank enters the engine through the fuel supply pipeline. The traditional float type fuel measuring system usually consists of two parts, including the float type fuel measuring sensor installed in the wing fuel tank and the display device installed on the cockpit instrument panel. The float type fuel oil measurement sensor has a built-in sliding rheostat. The float of the sensor always floats on the oil surface. As the fuel is consumed, the float drops with the oil level. The ratio of the resistance across the two ends. The display device installed on the instrument panel of the cockpit displays the...

Problems solved by technology

[0003] The measurement accuracy of the above-mentioned float fuel measurement system is greatly affected by the flight attitude. Generally speaking, when the pitch angle or roll angle of the aircraft exceeds ±5°, the accuracy of the measurement results is unacceptable

[0004] Aiming at the above technical problems, the study proposes a fuel measurement system that comprehensively utilizes large flight attitude changes, which can still maintain a certain measurement accuracy when the aircraft makes large-scale maneuvers, so as to solve the defects of the traditional float fuel measurement system.
