Large-scale airplane fuel oil system test device

Abstract

The invention discloses a large-scale aircraft fuel system test device, which belongs to the field of aviation industry, and comprises a trailer, a tank-shaped fuel tank, a purification and refueling module and an electronic control module, the tank-shaped fuel tank is fixedly connected to the top of the trailer, and the The purification and refueling module is arranged on the trailer and connected with the tank-like fuel tank, the electronic control module is arranged on the trailer and connected with the purification and refueling module through wires, and the device connects the tank-like fuel tank through the trailer. The fuel tank is transported to the designated location. The device has four functions: aircraft gravity refueling, transfer fuel tank aircraft refueling, transfer fuel tank purification, and self-circulation purification functions. It can independently complete the calibration of large aircraft fuel oil. Its unique design improves Efficiency, the device is designed with a refueling channel and a fuel return channel, and the refueling and fuel return cycle calibration can be performed at the same time during the aircraft fuel system test. This device reduces measurement errors, improves accuracy, reduces costs, and improves equipment durability.

Description

technical field [0001] The invention relates to the field of aviation industry, in particular to a large aircraft fuel system test device. Background technique [0002] There may be inconsistencies between the indication of the fuel gauge of the newly developed large-scale aircraft fuel system and the actual fuel load of the aircraft, and the fuel gauge must be calibrated. There are three aspects to the calibration of the fuel system fuel volume: one is the calibration of the zero position of the fuel volume; the other is the calibration of the full fuel volume of the fuel volume; the third is the calibration of the linearity of the fuel volume. [0003] In the prior art, the calibration of the fuel volume of large aircraft is realized by the equipment of the refueling truck, which uses the fuel pump of the fuel truck to add fuel into the fuel tank of the aircraft, and calculates the refueling volume by relying on the indication readings on the fuel truck equipment . The m...

Problems solved by technology

The measurement error of this method is relatively large, and the use of oil truck equipment to recover the fuel after the aircraft test can easily cause damage to the filter element of the oil truck (because the oil truck is designed to refuel and return oil to the same channel) and fuel pollution, resulting in huge use costs waste
