Embodiment Construction

[0062] The invention provides an electronically controlled landing gear operating system. The system of the present invention is shown in FIG. 3 .

[0063] The operating system has door control channels 16 and landing gear control channels 15 . These channels are controlled by the master control unit.

[0064] In the present invention, the door control channel 16 has at least one locking device for each door, at least one actuating unit for each door and a control unit for the actuating unit. As explained above, the landing gear bay of an aircraft has several doors, namely one or more main doors and at least one secondary door. The invention will be described for application to main landing gear doors. It must be pointed out that the present invention can also be applied to all the main doors of the aircraft (assuming the aircraft has several main doors) and to one or more auxiliary doors of the aircraft, it being understood that in this case the auxiliary doors are Leave ...

Abstract

The invention concerns a system for maneuvering an aircraft landing gear mounted in a landing gear box closed by a set of hatches, comprising: a general control unit of the landing gear box to trigger the different maneuvers, a control channel for the hatches (16), a control channel for the landing gear (15), the general control unit, the hatch control channel and the landing gear control channel being controlled by an electric power source, when the aircraft is in normal operating conditions, emergency operating conditions and in maintenance phase. The invention also concerns an aircraft comprising such a system.

Description

technical field [0001] The invention relates to a system for manipulating the landing gear of an aircraft. The landing gear operating system is the system used to deploy or retract the landing gear relative to the aircraft fuselage. In many aircraft the landing gear is retractable, ie it is mounted hinged in a gear well within the fuselage of the aircraft. Thus, during the cruise phase, the landing gear remains inside the fuselage, located in the gear well, closed by a set of doors. Before the landing phase of the aircraft, the undercarriage is deployed, or protrudes from the undercarriage bay after opening the above-mentioned door. The present invention relates to a system for controlling door opening and landing gear deployment during normal operation, emergency operation and maintenance phases. [0002] The invention can be applied in the field of aviation, especially in the field of deployment and / or retraction of landing gear. Background technique [0003] Currently...
