Gas Extraction System for Aircraft Vibration Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vibration control systems for aircraft, such as those using gas accumulators, face inefficiencies due to gas bubbles in the working fluid, which affect damping performance and cannot modify dynamic pressure without compromising gas bubble removal.
Innovation Solution
A gas extraction system with a cap and conduits that channels fluid and gas bubbles into a gas reservoir, allowing for efficient removal of bubbles while minimizing fluid dynamic pressure losses and accommodating thermal expansion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a gas extractor system with conduits is used to remove gas bubbles, then gas bubble removal efficiency is improved, but fluid dynamic pressure losses increase
Solution Approach 1:
The patent employs a porous plate instead of conventional conduits to separate gas bubbles from the working fluid. The porous structure allows fluid to pass through with minimal pressure drop while effectively extracting gas bubbles, thus resolving the contradiction between gas removal efficiency and fluid dynamic pressure losses.
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 removes gas bubbles, maintaining damping efficiency and allowing for dynamic pressure adjustments without adverse effects, thus enhancing vibration control in aircraft.
Implementation Method 1
a flow restriction system configured to create a pressure differential across the porous plate during operation
Implementation Method 2
a porous plate configured to separate gas bubbles from the working fluid
Implementation Method 3
Vibration control systems are well known in the art and are effective means to control the vibrations exerted against a non-vibration object by a vibrating object

AI summary
A vibration control system includes an outer housing, an inner housing carried within the outer housing, a fluid passage extending through the inner housing and in fluid communication with a first fluid reservoir and a second fluid reservoir on opposing sides of the inner housing, and a gas extraction system. The gas extraction system includes a gas reservoir in fluid communication with the first fluid reservoir, a removable cap secured to the outer housing, a lid removably attached to the cap, and a plurality of conduits extending through cap and lid and configured to provide fluid and gas communication between the first reservoir and the gas reservoir.
