Problems solved by technology

[0003] Testing of aircraft fuel tank systems can be quite time consuming, in some cases up to 8 hours
It is very uncomfortable for the operator to operate the emergency brake for such a long time
In addition, there is the risk that the test will be interrupted unexpectedly by the operator, for example, by mistake not pressing the emergency stop button due to inattention

Embodiment Construction

[0025] Apparatus 10 for testing an aircraft fuel tank system 12 includes a fuel supply 14 in the form of a refueling cart including a fuel reservoir 16 . A fuel supply reservoir 16 is connected to a first end of a fuel supply line 18 . A second disconnect of the fuel supply line 18 is connected to a fuel outlet 20 of the fuel supply device 14 .

[0026] A first isolation valve 22 is provided in the fuel supply line 18 which, in the closed state, interrupts the supply of fuel from the fuel reservoir 16 to the fuel outlet 20 of the fuel supply 14 . Conversely, in the open state, the first isolation valve 22 allows fuel to be supplied from the fuel reservoir 16 to the fuel outlet 20 of the fuel supply 14 . A fuel pump 24 is provided in the fuel supply line 18 downstream of the first isolation valve 22 for delivering fuel from the fuel reservoir 16 .

[0027] A fuel outlet 20 of the fuel supply 14 is connected to a first end of a fuel delivery line 26 via a suitable coupling mem...

Abstract

A kind of device used in detecting the airplane oil basin includes the fuel supplying equipment and this fuel supplying equipment includes the fuel container, the fuel supplying pipe used to supply the fuel to the fuel outlet of fuel supplying equipment from the fuel container and the first isolated valve set in the fuel supplying pipe. The equipment said above also includes: the fuel delivery pipe which is used to supply the fuel to air oil basin system from the fuel outlet of fuel supplying equipment; and the second isolated valve set in the fuel delivery pipe. The electronic control unit of this equipment (ECU) suits to the first isolated valve and the second isolated valve and responses to the test reference signal supplying to the electronic control unit of the device and corresponds to breaking the fuel supply by the fuel supplying pipe and the fuel delivery by the fuel delivery pipe.

Description

technical field [0001] The present invention relates to apparatus and methods for testing aircraft fuel tanks. Background technique [0002] During the final assembly of an aircraft, the aircraft fuel tank system must be tested to ensure proper operation of the aircraft fuel tank system control equipment, particularly the fuel level control. Additionally, this test is used to detect leaks in the fuel tank system. Testing of the aircraft fuel tank system involves supplying a predetermined amount of fuel from a fuel reservoir to the fuel tank system. For safety reasons, equipment used to test aircraft fuel tanks often includes an emergency shutdown device that interrupts the test in the event of a safety emergency, such as an overpressure situation in one of the aircraft fuel tanks being tested . Furthermore, the supply of fuel from the fuel reservoir is usually controlled by a deadman device. If the operator fails (for example at equal intervals or continuously) to press ...
