Modular Environmental Chamber for Aircraft Moisture Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for evaluating moisture management designs in aircraft interiors are ineffective, as they typically require in-service troubleshooting after the aircraft is built, leading to difficulties in developmental testing and phased improvements.
Innovation Solution
A modular environmental control chamber (MECC) that simulates different temperature and humidity conditions by separating into an outer and inner chamber, allowing for controlled airflow and environmental control, enabling the testing of moisture accumulation and management systems under flight-like conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If moisture management design is installed on an aircraft and tested under actual flight conditions, then the design can be evaluated in real-world conditions, but corrections or improvements can only be implemented after the aircraft interior is already designed and built
Solution Approach 1:
The patent creates a test chamber that replicates aircraft interior conditions, allowing moisture management designs to be tested before actual aircraft installation. This preliminary testing enables design evaluation and improvement in advance, avoiding the need for post-installation troubleshooting and reducing development time delays
2Measurement precision
If a test chamber is designed to exactly replicate aircraft interior conditions, then testing accuracy is improved, but the complexity and cost of the test chamber increases
Solution Approach 1:
The test chamber applies different environmental conditions to different zones within the chamber, replicating specific aircraft interior conditions (such as cold outer surfaces and warmer interior air) without requiring the entire chamber to be equally complex. This localized approach to environmental control achieves testing accuracy while managing system complexity
3Adaptability or versatility
If the test chamber uses separate inner and outer chambers to simulate aircraft insulation layers, then the ability to simulate flight conditions is improved, but the device complexity increases
Solution Approach 1:
The test chamber employs a nested structure with an inner chamber containing the test specimen and an outer chamber surrounding it, simulating the aircraft's insulation layers. This nesting arrangement enables sophisticated environmental simulation (different temperatures, humidity conditions) while containing the complexity within a compact, organized structure rather than requiring separate distributed systems

AI summary
An example modular environmental control chamber (MECC) includes an outer chamber formed by an outer chamber housing section enclosing an outer face of a section of fuselage and an inner chamber formed by an inner chamber housing section enclosing an inner face of the section of fuselage. An outer chamber airflow delivery and return system includes an outer chamber blower for directing temperature-controlled air to the outer chamber through an air inflow aperture of the outer chamber housing section and an outer chamber air return duct connected to an air outflow aperture of the outer chamber housing section. An inner chamber airflow delivery and return system includes an inner chamber blower for directing humidity-controlled air to the inner chamber through an air inflow aperture of the inner chamber housing section and an inner chamber air return duct connected to an air outflow aperture of the inner chamber housing section.
