HINGE ASSEMBLY FOR AN AIRCRAFT DOOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 17971857 titled 'HINGE ASSEMBLY FOR AN AIRCRAFT DOOR
The abstract describes a hinge assembly for connecting a door to an aircraft fuselage, featuring a programmable gear assembly that allows the door to maintain a parallel orientation relative to the fuselage as it opens and closes.
- The hinge assembly includes a hinge arm with a fuselage fitting pivotably coupled to a fuselage rotatable interface and a door fitting pivotably coupled to a door rotatable interface.
- A programmable gear assembly is coupled to the hinge arm, consisting of a fuselage gear, a door gear, and a rack operably coupled between the two gears.
- The programmable gear assembly enables the door to pivot around the fuselage fitting while maintaining a parallel orientation to the fuselage during the opening and closing process.
Potential Applications: - Aerospace industry for aircraft doors - Industrial machinery with similar door mechanisms
Problems Solved: - Ensures the door maintains a parallel orientation to the fuselage during operation - Provides a smooth and controlled opening and closing mechanism
Benefits: - Improved functionality and efficiency in door operation - Enhanced safety and stability during aircraft operation
Commercial Applications: - Aircraft manufacturing and maintenance companies - Industrial machinery manufacturers
Prior Art: Readers can explore prior patents related to aircraft door hinge assemblies and programmable gear mechanisms to understand the evolution of this technology.
Frequently Updated Research: Stay updated on advancements in aerospace engineering and mechanical systems to discover new innovations in door hinge assemblies and gear mechanisms.
Questions about the technology: 1. How does the programmable gear assembly contribute to the smooth operation of the door hinge assembly? 2. What are the key advantages of maintaining a parallel orientation between the door and fuselage during operation?
Original Abstract Submitted
A hinge assembly for connecting a door to a fuselage of an aircraft includes a hinge arm having a fuselage fitting pivotably coupled to a fuselage rotatable interface and a door fitting pivotably coupled to a door rotatable interface. The hinge assembly includes a programmable gear assembly coupled to the hinge arm allowing the hinge arm to pivot around the fuselage fitting when the door is moved from a door closed position to a door open position and causing the door to maintain in a generally parallel orientation relative to the fuselage between the door closed position to the door open position. The programmable gear assembly includes a fuselage gear coupled to the fuselage fitting, a door gear coupled to the door fitting, and a rack operably coupled between the fuselage gear and the door gear.
