Problems solved by technology

figure 1 The J in the APU and the signal line 1 and signal line 2 on the left side of the front firewall of the APU need to be installed on each aircraft, which will increase the weight of the aircraft and the cost of a single aircraft
Especially with the advancement of technology, the reliability of the intake damper actuator has reached the order of 100,000 flight hours, and the faulty intake damper actuator will usually be replaced quickly, so that in most during flight time figure 1 The J in and the signal line 1 and signal line 2 on the left side of the front firewall of the APU will not be used, resulting in a large unnecessary increase in aircraft weight and unit cost

Embodiment Construction

[0012] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0013] see figure 2 , which shows a connection diagram of the APU air intake door actuator, the connector plug P1, the connector socket J1 and the APU according to an embodiment of the present disclosure.

[0014] As shown in the figure, according to an aspect of the present disclosure, the connector plug P1 includes a drive signal line interface and a position signal line interface for connecting to the intake door actuator on one side thereof and a position signal line interface on the other side thereof. The drive signal line interface and the position signal line interface are docked with the connector socket. Among them, the drive signal line interface is used to connect the drive signal line, and the drive signal line is used to supply power to the actuator motor to open or close the intake damper, while the position signal line interface is used to connect ...

Abstract

The invention relates to an APU air inlet air door actuator fault processing method and device. A connector plug used for butting with a connector socket at a firewall in front of an APU compartment is provided. An APU air inlet air door actuator fault detection and processing method is provided.

Description

technical field [0001] The present disclosure relates to aircraft APU system control. Background technique [0002] Civil aircraft, especially large passenger aircraft, usually require that the APU system should work normally when flying, so as to ensure that the aircraft has available auxiliary air sources and power sources. Therefore, in order to improve the dispatch reliability of the aircraft, in the design of the APU system, measures should be provided to ensure that the APU system can still be started, operated and parking. [0003] The current practice is that in the case of failure of the APU intake damper actuator, the maintenance personnel manually open the APU intake damper and fix it at a certain angle, and at the same time inform the APU controller through an electrical signal at the intake damper actuator. In this case, it is not necessary to operate the intake damper when starting, running and stopping the APU. [0004] E.g, figure 1 This solution in the p...
