[0027] Helicopter Fuel Indicating System Calibration Process

[0028] 1) Connect the oil return line of the tester to the oil supply line of the helicopter engine to simulate the oil supply from the helicopter to the engine so as to calculate the return oil quality, pressure and flow parameters.

[0029] 2) Turn on the power of the tester, turn on the switches of each pipeline, operate the tester to add an appropriate amount of fuel to the helicopter, and the tester will automatically record the quality A of the added fuel.

[0030] 3) Turn on the fuel booster pump of the helicopter, and return fuel to the tester until no more fuel can be pumped out, and the tester will automatically record the returned fuel quality B.

[0031] 4) The difference between the total amount of added fuel A and the total amount of returned fuel B is the amount of non-fuel remaining in the helicopter fuel tank C=A-B. ,

[0032] 5) At this time, adjust the helicopter fuel indication system to make ...

Abstract

The invention discloses a calibration method for a helicopter fuel oil indication system, and belongs to the field of aircraft instruments. On the basis that a fuel oil test comprises the zero and full position correction and flow and pressure measurement for a fuel quantity measurement system, a fuel oil tester has an oiling function and can accurately measure the oiling quantity, has an oil returning function and can accurately measure the oil returning quantity, can accurately measure oiling and oil returning flows, and can accurately measure the oil returning pressure. The advanced control method is employed in the invention, pipelines are increased, the software is optimized, a pressure parameter display function is added, all the parameters can be integrally displayed, the operation is facilitated, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a method for calibrating a helicopter fuel indicating system, which belongs to the technical field of aviation instruments. Background technique [0002] The existing equipment control method is relatively old, the parameters such as fluid flow and quality cannot be displayed in a centralized manner, and there is no pressure indication, and the software control and pipeline design cannot meet the technical requirements of new products. Contents of the invention [0003] The purpose of the invention is to design a device to realize the calibration of the helicopter fuel indicating system. [0004] The technical scheme of the invention: a kind of calibration method to the helicopter fuel indicating system, it is characterized in that, this method comprises the following steps: [0005] 1) Connect the left and right engine oil supply joints of the helicopter to the oil return pipeline of the tester; [0006] 2) Control the con...
