Propellant Combining Explosive and Liquid for Focused Launch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ammunition rounds using cordite or gunpowder have limited propulsion capabilities, leading to wear and reduced accuracy in firearms over time due to unfocused explosions.
Innovation Solution
Replacing cordite with a combination of an explosive charge, such as a shaped high explosive, and a liquid like water, where the explosive compresses and evaporates the liquid to amplify the propulsion effect, potentially reducing barrel wear and maintaining accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If cordite or gunpowder is used as propellant, then the ammunition round can be manufactured with simple structure, but the propulsion capability is limited and causes barrel wear over time
Solution Approach 1:
The patent combines explosive charge and liquid propellant into a single integrated propellant system within the same casing. The explosive charge is positioned to directly contact and compress the liquid, creating a unified propulsion mechanism that achieves higher power output while maintaining manufacturing simplicity through integrated design.
Solution Approach 2:
The propellant system uses a composite approach by combining explosive material with liquid propellant. This composite propellant configuration allows the explosive to compress and evaporate the liquid, creating amplified propulsion effects while distributing the mechanical stress more evenly across the barrel, thereby reducing wear.
2Object-affected harmful factors
If conventional cordite explosion is used, then the propellant structure is simple, but the explosion is unfocused causing greater wear on the barrel
Solution Approach 1:
The patent applies local quality by shaping the explosive charge and positioning it to create a focused explosion at a specific location within the barrel. The explosive is configured to compress and evaporate the liquid propellant at a controlled point, concentrating the explosive energy in a localized manner that reduces distributed wear on the barrel while maintaining propulsion effectiveness.
3Duration of action of stationary object
If shaped high explosive is used to focus the explosion, then barrel wear is reduced, but the propellant system becomes more complex
Solution Approach 1:
The patent segments the propellant system into distinct functional zones: the explosive charge section and the liquid propellant section, separated by a divider. This segmentation allows the explosive to be shaped for focused compression of the liquid while keeping the overall design modular and manufacturable, balancing complexity reduction with enhanced performance.

Function Achieved in This Case
The solution provides a more powerful launch system with focused energy, reducing barrel damage and extending the service life of firearms by utilizing both thermal and kinetic energy from the explosion.
Implementation Method 1
The explosive may be conventional cordite or gunpowder or may be high explosive, and the high explosive may be a shaped charge, the shape for additional effect in focusing the directionality of the explosion. The liquid can be compressed by the explosion
Implementation Method 2
The liquid can be compressed by the explosion and then evaporate to amplify the effect of the explosion in propelling the projectile from the gun
Implementation Method 3
the high explosive may be a shaped charge, the shape for additional effect in focusing the directionality of the explosion
