Aircraft Wing Tip Anti-Icing Fluid Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for providing anti-icing fluid to aircraft wings and tail fins are inefficient, as conventional spraying methods often result in runoff, leaving these areas prone to icing.
Innovation Solution
An anti-icing fluid system with strategically located outlets on aircraft structural components, such as wing tips and tail fins, allows the fluid to run down the surfaces under gravity, ensuring comprehensive coverage and reducing icing risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If anti-icing fluid is sprayed onto wing tips and tail fins using conventional ground-based apparatus, then the fluid can be applied to the aircraft surfaces, but the fluid tends to run off, leaving these areas prone to icing
Solution Approach 1:
The patent positions fluid outlets at strategic locations (wing tips, tail fins, and leading edges) where gravity will cause the anti-icing fluid to run down and coat the surfaces before takeoff. This preliminary application ensures the surfaces are pre-covered with anti-icing fluid that will remain in place during flight, preventing ice formation accumulation.
Solution Approach 2:
The invention implements localized fluid delivery by placing outlets at specific high-risk areas such as wing tips, tail fins, and leading edges rather than using uniform spraying. Each outlet is positioned to deliver fluid precisely where gravity-driven runoff will provide maximum protective coverage, creating locally optimized anti-icing zones.
2Quantity of substance
If outlets are located in the main body of the wing, then anti-icing fluid can be delivered to the wing, but not all areas of the wing are effectively covered and the delivery is not efficient
Solution Approach 1:
The patent extends fluid delivery from the traditional two-dimensional wing surface to include three-dimensional extremities such as wing tips and tail fins. By positioning outlets at these extended locations, the system utilizes gravity to distribute fluid across multiple surfaces and angles, achieving comprehensive coverage of previously hard-to-reach areas.
Solution Approach 2:
The invention divides the anti-icing fluid delivery system into multiple segmented outlets distributed across different aircraft surfaces (wing tips, tail fins, leading edges). Each outlet independently serves a specific zone, ensuring complete coverage without reliance on a single centralized delivery point, thereby improving both coverage quantity and delivery efficiency.
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
The system effectively prevents ice formation and facilitates ice removal by ensuring uniform distribution of anti-icing fluid across the wing tips and tail fins, thereby enhancing aircraft safety and performance in cold weather conditions.
Implementation Method 1
The anti-icing fluid delivered through an outlet located at or near the tip of the upwardly-extending portion, or the base of the downwardly-extending portion may, under the influence of gravity, run down the surface of the component

AI summary
An aircraft structural component having an upwardly- or downwardly-extending portion, such as a wing tip or tail fin, comprising one or more outlets for the delivery of anti-icing fluid to a first surface of the aircraft structural component. Anti-icing fluid is delivered through an outlet located at or near the tip of the upwardly-extending portion, or the base of the downwardly-extending portion. The anti-icing fluid thus delivered may, under the influence of gravity, run down the surface of the component, thereby providing the surface of the component with anti-icing fluid.
