Large aircraft fuel system test device

Abstract

The invention discloses a large-scale airplane fuel oil system test device, and belongs to the field of aviation industry. The large-scale airplane fuel oil system test device comprises a trailer, a filling type fuel tank, a purification oiling module and an electric control module, wherein the filling type fuel tank is fixedly connected to the top of the trailer; the purification oiling module is arranged on the trailer and is connected with the filling type fuel tank; the electric control module is arranged on the trailer, and is connected with the purification oiling module through an electric wire; the device conveys the filling type fuel tank to a specified position through the trailer. The large-scale airplane fuel oil system test device has four functions including airplane gravity oiling, transfer oil tank airplane oiling, transfer oil tank purification and self circulation purification; the calibration work of the large-scale airplane fuel oil quantity can be independently completed; the design is unique; the efficiency is improved; an oil oiling passage and an oil return passage are respectively designed for the large-scale airplane fuel oil system test device; during the airplane fuel oil system test, the oiling and oil return circulation calibration work can be performed at the same time; the metering errors are reduced by the device; the precision is improved; the cost is reduced; the durability of equipment is improved.

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
