ARTICULATED HINGE ASSEMBLY FOR AN AIRCRAFT DOOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240309685 titled 'ARTICULATED HINGE ASSEMBLY FOR AN AIRCRAFT DOOR

The articulated hinge assembly described in the patent application is designed to connect a door to the fuselage of an aircraft using a complex system of hinge members and linkages.

The articulated hinge arm consists of a first hinge member pivotably coupled to a second hinge member at an elbow.
The first hinge member includes a fuselage fitting that is pivotably coupled to a fuselage bracket, while the second hinge member includes a door fitting pivotably coupled to a door bracket.
A linkage assembly is coupled to the articulated hinge arm, the fuselage fitting, and the door fitting, controlling the movement of the hinge members relative to each other and to the fuselage fitting.
The linkage assembly includes a hinge linkage assembly to control the movement of the hinge members and a door linkage assembly to control the positioning of the door between open and closed positions.

Potential Applications: - Aerospace industry for aircraft doors - Military aircraft - Commercial airlines

Problems Solved: - Secure and reliable connection of aircraft doors to the fuselage - Smooth and controlled movement of the door between open and closed positions

Benefits: - Enhanced safety and security in aircraft operations - Improved durability and longevity of door connections - Streamlined maintenance and repair processes

Commercial Applications: Title: Aircraft Door Hinge Assembly: Innovative Solution for Secure Door Connections This technology can be utilized by aircraft manufacturers, airlines, and military aviation for ensuring safe and efficient operation of aircraft doors. The market implications include improved aircraft safety standards, reduced maintenance costs, and enhanced passenger experience.

Questions about Aircraft Door Hinge Assembly: 1. How does the articulated hinge assembly improve aircraft safety and security? The articulated hinge assembly provides a secure and reliable connection between the door and the fuselage, ensuring that the door remains in place during flight and can be easily opened and closed as needed.

2. What are the potential cost-saving benefits of using this innovative hinge assembly in aircraft design? By improving the durability and longevity of door connections, the articulated hinge assembly can reduce maintenance costs for airlines and aircraft manufacturers, leading to overall cost savings in the long run.
