Aircraft Galley Cooling Duct Redesign
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional aircraft galley cooling systems require a large footprint due to the space needed for airflow supply and return components, limiting the available space for passenger seating and other uses.
Innovation Solution
The galley system reconfigures the airflow supply and return ducts to be positioned forward of the rear wall and between the mid-wall and bottom wall, reducing the depth of the galley and allowing for more passenger space by eliminating the need for ducts in the rear wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If airflow supply and return components (ducts, valves) are routed through the rear wall of the galley, then the galley can supply cooled air to cart compartments, but the galley depth increases by 4-5 inches requiring more cabin space
Solution Approach 1:
The patent repositions the airflow supply and return components from the rear wall to the side walls of the galley. This dimensional shift moves the components from a depth-oriented arrangement to a width-oriented arrangement, reducing galley depth while maintaining cooling functionality through alternative routing paths along the sides of cart compartments.
Solution Approach 2:
Instead of routing ducts through the rear wall as in conventional systems, the patent inverts the approach by routing supply and return ducts through the side walls. This inverted configuration eliminates the need for deep rear wall penetration and reduces the overall galley footprint in the depth direction.
2Area of stationary object
If the galley depth is reduced to free up cabin space for passenger seating, then more passenger area is available, but space for airflow supply and return components becomes limited
Solution Approach 1:
The patent resolves the space conflict by transitioning the airflow component layout from a depth-based arrangement to a width-based arrangement along the side walls. This allows the galley to maintain necessary cooling infrastructure while reducing depth to expand passenger area, effectively trading width utilization for depth reduction.
Solution Approach 2:
The patent segments the airflow supply and return system into separate side wall-mounted components rather than consolidating them in the rear wall. This segmentation allows independent optimization of each duct's position along the side walls, enabling compact integration that accommodates reduced galley depth while maintaining full cooling functionality.
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 configuration reduces the galley's depth by 3-4 inches, increasing passenger area space and potentially allowing for additional seating or other uses, while maintaining efficient air-over-cart cooling for galley carts.
Implementation Method 1
A supply duct supplies cooled airflow to the cart compartment

AI summary
A galley includes a cart compartment configured to receive at least one galley cart. The cart compartment is defined by a plurality of walls including a rear wall behind the cart compartment, side walls along sides of the cart compartment, a mid-wall above the cart compartment and a bottom wall below the cart compartment. Doors are coupled to the cart compartment to enclose and allow access to the cart compartment. A supply duct supplies cooled airflow to the cart compartment. The supply duct is positioned in the cart compartment forward of the rear wall and positioned in the cart compartment between the mid-wall and the bottom wall. The supply duct includes a supply device to allow airflow from an interior of the supply duct into the cart compartment.
