Embodiment Construction

[0028] Below by embodiment and accompanying drawing, the present invention will be further described:

[0029] see figure 1 , which is a functional block diagram of the aircraft air emergency oil discharge control system of the present invention. The aircraft air emergency oil discharge control system includes an air emergency oil discharge control panel 1, a controller 2, a power distribution device 3 and a controlled object. Wherein, the controlled objects include several emergency oil discharge pumps 5 and several emergency oil discharge valves 4 .

[0030] Two control channels of the air emergency oil discharge control board 1 for sending switch commands are connected to the controller 2 and the power distribution device 3 respectively. The channel of the controller 2 for driving the indicator light is connected to the air emergency oil drain control panel 1 , while the control channel for sending automatic commands is connected to the power distribution device 3 . The ...

Abstract

The invention belongs to an aerial oil drainage technology, and relates to an aerial emergency oil drainage control system and an aerial emergency oil drainage control method for an airplane. The control system comprises an aerial emergency oil drainage control board, a controller, a power distribution device and a controlled object. The control method comprises the following steps that: a manual mode and an automatic mode are switched and automatic oil drainage amount is preset by an oil drainage mode selection knob, and automatic control is invalid in the manual mode; oil drainage starting control method and principle are the same in the two modes, namely a control relay is locked to be switched on by a self-locking circuit when an oil drainage starting switch is turned on, and oil drainage is started; and oil drainage is stopped by an oil drainage stopping switch in the manual mode, and is automatically cut off by the controller according to the preset oil drainage amount in the automatic mode, and automatic oil drainage also can be overridden and interrupted by the oil drainage stopping switch. The aerial emergency oil drainage control system and the aerial emergency oil drainage control method are convenient, quick and reliable, the operating load of a unit is reduced, and system control reliability and the safety of the airplane are improved.

Description

technical field [0001] The invention belongs to the oil discharge technology in the air, and relates to an aircraft air emergency oil discharge control system and a control method thereof. Background technique [0002] The control of the aircraft air emergency fuel dump system is the key measure to realize the release of excess fuel on the aircraft in an emergency, so that the aircraft can quickly reduce its own weight and achieve the purpose of safe landing and climbing. At present, most aircraft equipped with emergency fuel draining systems in the air use power draining, that is, relying on emergency fuel drain pumps (or fuel booster pumps also serving as emergency fuel drain pumps) installed in each fuel tank as a power source to drain fuel out of the aircraft. Therefore, the air emergency oil discharge control usually includes the control of each emergency oil discharge pump and the control of each oil discharge valve on the emergency oil discharge pipeline, so as to rea...
