Multi-Chamber Combustion Gun Heat Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gun designs that utilize internal combustion chambers for bullet ejection face issues with extreme temperatures causing bullet deformation or explosion, as the heat from igniting volatile gases is directly applied to the bullet, leading to potential jamming or explosion.
Innovation Solution
A gun mechanism with multiple combustion chambers, where compressed fuel and oxidant gases are ignited in a first fixed chamber to create an expansion of gas that is directed towards subsequent movable chambers, which then propel the bullet, separating the initial ignition from the bullet and distributing the heat across multiple expansions to safely harness the expansion properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a single combustion chamber is used to ignite volatile gas mixture directly adjacent to the bullet, then the bullet can be propelled effectively, but the extreme heat generated causes bullet deformation or explosion
Solution Approach 1:
The single combustion chamber is divided into multiple combustion chambers arranged in sequence. The volatile gas mixture is ignited sequentially in each chamber, distributing the heat generation across multiple locations and time points rather than concentrating it all at once adjacent to the bullet. This segmentation allows the bullet to be propelled by the cumulative expansion while avoiding direct exposure to extreme temperatures from a single ignition event.
2Object-affected harmful factors
If multiple combustion chambers are used to distribute heat, then bullet deformation is prevented, but the device complexity increases
Solution Approach 1:
Multiple combustion chambers are combined within a single barrel structure, sharing common components such as the barrel itself, the volatile gas mixture supply system, and the bullet propulsion path. This merging approach allows the system to benefit from distributed heat generation while avoiding the full complexity of completely separate combustion systems, as the chambers utilize shared infrastructure.

Function Achieved in This Case
This design safely ejects bullets by distributing the heat and expansion across multiple chambers, reducing the risk of deformation or explosion and minimizing recoil, allowing for efficient and reliable operation with various types of ammunition.
Implementation Method 1
Compressed fuel and oxidant gas are introduced into the chamber to form a volatile mixture, which is ignited to eject the bullet from the barrel
Implementation Method 2
the ignition in the first chamber creates an expansion of gas, which is directed towards the second and further subsequent chamber or chambers to move them forward
Implementation Method 3
a gas compression means adapted to provide compressed fuel and oxidant gas to form volatile mixtures in the combustion chambers
Implementation Method 4
subsequent combustion chamber or chambers being movable in the direction of the barrel... to eject the bullet from the barrel

AI summary
A gun having at least two combustion chambers, a first combustion chamber being fixed within the gun, subsequent combustion chamber or chambers being movable in the direction of the barrel, wherein the trigger mechanism is adapted to ignite the volatile mixture in the first chamber; and the gun having means to regulate the timing of ignition of the volatile mixtures in the subsequent chamber or chambers to eject the bullet for the barrel. A reloading plate prevents a bullet being loaded, while the volatile mixtures are ignited.
