Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fluid systems in aircraft propulsion and lift generation do not effectively address debris entry, which reduces efficiency and do not provide alternatives for altering fluid flow to enhance propulsion and lift.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conduit is used to combine propulsion and lift-generating systems, then system integration and efficiency are improved, but debris can enter the conduit and reduce system effectiveness
Solution Approach 1:
The fluid passage is divided into multiple sections with strategic openings (first opening, second opening, third opening) that allow selective access to the passage interior. This segmentation enables debris to be introduced into specific zones while maintaining overall system integration, resolving the contradiction between unified conduit design and debris exclusion.
Solution Approach 2:
The patent introduces an intermediary substance or mechanism within the conduit that facilitates debris management. This intermediary element allows the conduit to maintain its integrated propulsion and lift functions while simultaneously addressing debris contamination through controlled interaction points.
2Device complexity
If fixed fluid flow configuration is used in the conduit, then system simplicity is maintained, but propulsion and lift efficiency cannot be optimized under varying conditions
Solution Approach 1:
The fluid passage incorporates moveable elements or adjustable openings that allow the flow configuration to change dynamically based on operational requirements. This enables the system to optimize propulsion and lift efficiency under varying flight conditions while maintaining a relatively simple base structure, resolving the contradiction between simplicity and adaptability.
Solution Approach 2:
The patent allows for changes in flow parameters (such as flow direction, velocity distribution, and pressure gradients) through controlled modification of the passage geometry or opening positions. This parameter adjustability enables efficiency optimization without requiring complete system redesign, balancing simplicity with performance adaptability.

AI summary
A fluid system has a lengthwise axis, a chord length, a first body portion, a second body portion, a spacer, and a fluid pressurizer. The first body portion and the second body portion cooperatively define an injection opening, a suction opening, and a channel that extends from the injection opening to the suction opening. The fluid pressurizer is disposed within the channel cooperatively defined by the first body portion and the second body portion. The first body portion defines a cavity that is sized and configured to filter debris that enters the channel during use and provide a mechanism for removing the debris from the system.
