Problems solved by technology
In this low oil level warning method, since each wing oil collection tank is only equipped with a low oil level signaler, which is installed at a relatively high position in the oil collection tank, during the refueling process of the aircraft, the low oil level alarm signal lasts for a long time and then disappears. ; When the amount of refueling is small, the oil level in the fuel tank after refueling is lower than the low oil level warning oil level height, and the low oil level warning signal continues to send out warning signals; The amount of fuel in the fuel tank is quite different from the amount of fuel in the low fuel level warning, which leads to misjudgment by the pilot and affects the completion of the flight mission

Embodiment Construction
[0014] The present invention will be further described by way of specific embodiments in conjunction with the accompanying drawings:
[0015] see figure 1 , in this embodiment, the low oil level warning method for large transport aircraft includes: a fuel collection tank 1, a bulkhead check valve 2, an inner compartment low oil level signaler 3, an inner compartment 4, an outer compartment 5, Wing fuel tank 6, semi-sealed rib 7, low oil level signaler 8 of oil collection tank, low oil level warning device 9.
[0016] The wing fuel tank 6 is divided into a fuel tank 1, an inner compartment 4 and an outer compartment 5 by a semi-sealed rib 7, and the top of the semi-sealed rib 7 has a through hole for oil spillage and ventilation. The low oil level alarm annunciator is arranged in the oil collection tank 1 and the inner compartment 4, and the low oil level annunciator 8 of the oil collection tank is installed at the oil level position where the low oil level alarm is triggered ...

The invention belongs to the design of an aircraft warning, in particular to a low oil level warning method for a large transport aircraft. At present, when the aircraft is flying at a high attitude, it is easy to give an early warning or the fuel quantity in the aircraft's fuel tank during the warning is quite different from the low fuel level warning fuel quantity, which leads to the pilot's misjudgment and affects the completion of the flight mission. The low oil level warning method for a large transport aircraft provided by the present invention solves the problem that the low oil level warning signal will give a long-term warning when refueling on the ground by arranging high and low oil level signals in the fuel collecting tank and the inner compartment respectively; When the low fuel level is low, the low fuel level warning signal is continuously issued; at the same time, when the aircraft is flying at a high attitude, the fuel level in the aircraft fuel tank and the low fuel level warning fuel level are greatly different when the low fuel level early warning and warning are issued. It improves the reliability of the low fuel level warning, and ensures that the pilot can judge the remaining fuel quantity of the aircraft and complete the flight mission.
Description
technical field [0001] The invention belongs to aircraft alarm design, in particular to a low oil level alarm method for large transport aircraft. Background technique [0002] Large-scale transport aircraft usually use left and right symmetrical arrangement of wing fuel tanks to supply fuel to the engine, and each wing fuel tank for fuel supply is symmetrically set with an independent low fuel level warning signal to provide warning information to the pilot. The warning principle is that each aircraft A low oil level signaler is installed in the wing oil tank, and when the aircraft is cruising and flying, an alarm signal will be sent when the oil in the wing fuel tank reaches the low oil level warning oil level. In this low oil level warning method, since each wing oil collection tank is only equipped with a low oil level signaler, which is installed at a relatively high position in the oil collection tank, during the refueling process of the aircraft, the low oil level ala...
