Embodiment

[0036] Example: see Figure 1 to Figure 3 . The fuel tank of a certain model is the integral fuel tank of the wing, which is flat. When the aircraft is skidding or rolling, the oil level in the fuel tank changes greatly. At the same time, considering the uninterrupted supply of fuel to the engine in various attitudes of the aircraft, the overall fuel tank of the wing is divided into two parts: the consumption compartment and the large fuel tank. This method is now used to optimize the layout of the oil quantity sensor in the large fuel tank, and the same method can be used for the oil quantity sensor in the consumption compartment. Since the overall fuel tank of the wing is arranged along the span direction, although the shape of the fuel tank is relatively regular, it is longer along the span direction. The large fuel tank is about 4.2 meters long from the 5th rib to the 18th rib of the wing. When arranging the fuel quantity sensor, first determine a Primary sensor locatio...

Abstract

The invention belongs to the field of arrangement for fuel oil quantity measuring systems of airplanes, and particularly relates to an arrangement method for the fuel oil quantity sensors of airplanes. Any oil tank is provided with a neutral surface, and the liquid level height of fuel oil with equal volume is equal at the neutral position when the oil tank is in rolling and pitching attitudes. The method comprises the following steps of: determining a straight line by the intersection point of the fuel oil levels of two airplanes in a parking state and a rolling-angle state as a neutral line, and arranging the fuel oil quantity sensors of the airplanes on the neutral line. Utilizing the method, design cycle can be greatly shortened, and accurate measurement for oil quantity in each state of oil tank based on achieving high-accuracy demand can be satisfied.

Description

technical field [0001] The invention belongs to the field of arrangement of aircraft fuel oil quantity measuring systems, and in particular relates to an arrangement method of an aircraft fuel oil quantity sensor. Background technique [0002] In order to be able to provide the crew with fuel quantity information during the flight, a fuel quantity sensor needs to be installed in the aircraft fuel tank, and a capacitive fuel quantity sensor with very mature technology is used. Its number is determined with the complexity of the aircraft fuel tank, and the number of oil quantity sensors for large passenger aircraft or transportation can reach more than 20. In this way, the determination of the installation position and the number of sensors has become a key technology in the oil quantity measurement system. [0003] The current design method is mainly based on the complexity of the fuel tank. For a more regular fuel tank, such as a rectangular parallelepiped or cylindrical sh...
