Abstract

The invention discloses an aircraft fuel oil measurement system and an aircraft with the same. The aircraft fuel measurement system includes: a first fuel quantity measurement sensor and a second fuel quantity measurement sensor, the first fuel quantity measurement sensor and the second fuel quantity measurement sensor are arranged in the left wing fuel tank; There are a first fuel quantity measuring sensor and a second fuel quantity measuring sensor; a fuel measuring computer, a first processing unit and a second processing unit are arranged in the fuel measuring computer, and the first processing unit is connected with the first fuel measuring sensor; the second The processing unit is connected to the second oil quantity measuring sensor. In the aircraft fuel measurement system of the present invention, the first processing unit and the second processing unit transmit information to each other to obtain the information obtained by the other party. When any one of the first fuel quantity measurement sensor or the second fuel quantity measurement sensor is broken , capable of oil quantity measurement by another oil quantity measurement sensor.

Description

technical field [0001] The invention relates to the technical field of aviation fuel system design, in particular to an aircraft fuel measurement system and an aircraft with the same. Background technique [0002] With the gradual development of aviation technology, the fuel measurement system is also striving for higher usability and lower weight cost while pursuing measurement accuracy. Under the premise that a large number of off-the-shelf products are used in the system, how to use fewer sensors to ensure measurement accuracy and improve system availability has become an urgent problem for designers to solve. On the basis of ensuring that the mean time between failures (MTBF) of the fuel measurement system is not less than 12000FH, building a reasonable fuel measurement system will have a greater impact on the economy. [0003] The fuel measurement system used by a certain type of aircraft is mainly equipped with 18 fuel measurement sensors, a dual-channel measurement c...
