Aircraft Cabin Floor Air Distribution via Integrated Panel Cavities
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an efficient and space-saving way to supply air within the cabin area of an aircraft, as existing methods often occupy valuable space and are not highly integrated.
Innovation Solution
An aircraft cabin floor arrangement with air distribution is provided, comprising a plurality of floor panels with elongate cavities aligned transversely, and at least one air supply connected to these cavities to distribute air efficiently across the cabin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If air supply ducts are arranged in the ceiling area or below the cabin floor, then air supply function is provided, but valuable space is occupied and device complexity increases
Solution Approach 1:
The air supply ducts are merged with the floor panels to form an integrated structure. The floor panels themselves serve as the air distribution system, eliminating the need for separate ceiling or under-floor duct arrangements. This combining of structural and functional elements resolves the space occupation issue while maintaining air supply capability.
Solution Approach 2:
The floor panels are designed to serve multiple functions: they provide structural support for the cabin floor and simultaneously function as air supply ducts. This multi-functionality eliminates the need for dedicated air supply spaces, as the floor structure itself performs both mechanical and aerological roles.
2Volume of moving object
If air supply is integrated within floor panels, then space is saved and aircraft diameter can be reduced, but manufacturing complexity increases
Solution Approach 1:
The air supply system is segmented into multiple individual ducts distributed across the floor panels. Rather than requiring a single large duct, the system uses numerous smaller channels formed within the panel structure. This segmentation allows the air supply function to be integrated into the floor panels without requiring complex large-scale modifications, making the manufacturing more manageable.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution provides an efficient and highly integrated air distribution system that saves space, allowing for reduced aircraft diameter and improved performance by integrating air supply within the floor panels.
Implementation Method 1
The at least one air supply is fluidly connected to at least a part of the elongate cavities of the floor panels for supplying air from the at least one air supply to the elongate cavities
Implementation Method 2
a second part of the elongate cavities is provided as insulation cavities used for providing thermal insulation to thermally insulate the air supply cavities
