Pressure-Sealed Pipe Passage Assembly for Air Vehicle Fluid Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fluid leakage occurs during transfer between areas of varying pressure in air and/or space vehicles due to pressure differences and leakage through pipe-joint parts.
Innovation Solution
A transmission system with a body separating areas of different pressures, featuring pipes with flanges and sealing elements to prevent fluid leakage, and a passage element with an inner sealing extension to enhance sealing and regulate fluid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If simple pipe connections are used between pressure areas, then device complexity is reduced, but fluid leakage occurs due to pressure differences
Solution Approach 1:
The pipe connection system is divided into multiple functional segments: a first pipe in the first pressure area, a second pipe in the second pressure area, and a passage element with sealing components. This segmentation allows each component to be optimized for its specific function while maintaining overall system reliability against pressure differences.
Solution Approach 2:
The passage element acts as an intermediary component between the first pipe and second pipe, which are located in different pressure areas. The passage element includes sealing structures that mediate the fluid transfer while preventing leakage caused by pressure differences, thus resolving the contradiction between simple connection and reliable sealing.
2Reliability
If multiple sealing elements are added to prevent leakage, then sealing performance is improved, but device complexity increases
Solution Approach 1:
Multiple sealing functions are merged into a single integrated passage element. The passage element combines a first sealing structure (including a first sealing element and first sealing extension) and a second sealing structure (including a second sealing element and second sealing extension) into one component, achieving reliable sealing without proportionally increasing device complexity.
Solution Approach 2:
The passage element serves multiple functions simultaneously: it connects the first pipe and second pipe, provides sealing against pressure differences, and regulates fluid flow. This multi-functionality reduces the need for separate components, maintaining device complexity at an acceptable level while improving sealing performance.
3Strength
If flanges with fasteners are used to connect pipes, then connection strength is improved, but ease of operation is reduced
Solution Approach 1:
The connection system is segmented into modular components (first pipe with flange, passage element, second pipe with flange) that can be independently assembled and disassembled. This segmentation maintains connection strength through flange-fastener joints while improving ease of operation by allowing systematic assembly and disassembly procedures.

AI summary
A body separates areas on an air vehicle from each other. A plurality of pipes are located on both sides of the body in connection with the body and allow fluid to be transferred therethrough. An opening located on the body provides fluid passage between the pipes. A plurality of fasteners enable the pipes to be connected to each other and/or to the body. A flange extends outward from the pipe to allow the fasteners to be placed thereon. At least one sealing element is located between the flange and the body to provides sealing during the passage of the fluid between the pipes. A first pipe and a second pipe are connected on the body in an opposed manner such that the opening is therebetween.
