Submarine Diving Cell Gas Heating for Deep Emergency Ascent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing submarine blowing devices using stored compressed gas can only effectively empty diving cells up to 150 meters due to heat loss during volume change work, limiting emergency ascent capabilities, while gas generators for deeper dives are expensive and pose safety risks.
Innovation Solution
Heating the compressed gas within the diving cell using a heat source, such as a gas generator, to compensate for heat loss and increase water displacement volume, allowing emergency ascent from greater depths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If stored compressed gas is used to blow out diving cells, then operational readiness and cost-effectiveness are improved, but the maximum diving depth is limited to approximately 150 meters
Solution Approach 1:
The patent applies parameter changes by heating the compressed gas before introduction into the diving cell. This temperature increase causes thermal expansion of the gas, increasing its volume and buoyancy effect. The heated gas compensates for the high counterpressure at greater depths, enabling effective blow-out operations beyond the conventional 150-meter depth limit while maintaining the use of stored compressed gas.
2Reliability
If gas generators are used to enable complete blow-out from depths greater than 150 meters, then emergency ascent capability is improved, but cost and operational readiness deteriorate due to expense and inability to reuse
Solution Approach 1:
The patent replaces the expensive, single-use gas generator system with a reusable stored compressed gas system. By heating the stored gas, the patent achieves the same deep-diving blow-out capability without requiring disposable gas generators. The compressed gas tanks can be refilled and reused multiple times, dramatically improving operational readiness and reducing costs while maintaining emergency ascent capability from depths greater than 150 meters.
3Reliability
If gas generators are used for emergency inflation, then blow-out capability at great depths is improved, but safety and equipment integrity worsen due to high operating temperatures endangering paint- and heat-sensitive parts
Solution Approach 1:
The patent extracts the heating function from the gas generator system and applies it separately to the stored compressed gas before introduction into the diving cell. This separation allows controlled heating of only the gas needed for blow-out, rather than generating high temperatures within the diving cell environment. The heated gas is introduced quickly, minimizing thermal exposure to heat-sensitive parts while maintaining the blow-out capability at great depths.
