Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Muzzle brakes effectively reduce recoil but increase noise, percussion, and dust signature, while suppressors reduce noise and signature but offer limited recoil reduction, posing challenges for firearms that require both noise suppression and recoil management.
Innovation Solution
An integrated muzzle braked suppressor (MBS) with multiple radial/lateral ports and axial baffles that divert propellant gas at an angle to reduce recoil and multiple expansion chambers to minimize noise and recoil, featuring radial or lateral expansion chambers connected by orifices to optimize gas pressure, velocity, and temperature, with exhaust ports directed to reduce recoil and muzzle blast.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a muzzle brake is used to reduce recoil, then recoil reduction is improved, but noise and dust signature increase
Solution Approach 1:
The suppressor is divided into multiple axial stages with multiple radial/lateral expansion chambers in each stage. This segmentation allows the propellant gas to be expanded and cooled progressively through numerous small openings and orifices, reducing noise and dust signature while maintaining recoil reduction benefits
Solution Approach 2:
The invention adds radial and lateral expansion chambers that extend perpendicular to the axial direction, creating a three-dimensional gas expansion path. This multi-dimensional approach increases the surface area for gas cooling and noise reduction while maintaining effective recoil management
2Object-generated harmful factors
If a suppressor is used to reduce noise, then noise reduction is improved, but recoil reduction is limited
Solution Approach 1:
The invention merges the noise reduction function of a suppressor with the recoil reduction function of a muzzle brake into a single integrated device. The radial/lateral expansion chambers provide suppressor-like noise reduction while the configured openings and orifices redirect propellant gas to generate forward thrust for recoil reduction
Solution Approach 2:
The integrated muzzle braked suppressor performs multiple functions simultaneously: noise suppression through expansion chambers, recoil reduction through gas redirection, and dust signature reduction through controlled expansion. This multi-functional design eliminates the need to choose between noise control and recoil management
3Object-generated harmful factors
If multiple axial stages with radial/lateral expansion chambers are used, then noise and recoil reduction are improved, but device complexity increases
Solution Approach 1:
Multiple radial/lateral expansion chambers are nested within each axial stage, with chambers contained within one another or arranged concentrically. This nesting approach maximizes the noise and recoil reduction capability within a compact structure, reducing the overall device complexity compared to distributed separate chambers
Solution Approach 2:
Different regions of the suppressor have specialized functions: axial stages for sequential gas expansion, radial/lateral chambers for multi-directional expansion and cooling, and specifically configured openings/orifices for gas redirection. This local optimization allows each component to contribute efficiently to noise and recoil reduction
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 MBS significantly reduces noise and recoil while eliminating the dust signature, offering more effective noise reduction than traditional suppressors and recoil reduction than muzzle brakes, while directing the muzzle blast to minimize visible signature.
Implementation Method 1
redirect the propellant gas to counter the recoil forces
Implementation Method 2
the velocity is significantly greater (typically twice the velocity of the projectile). Consequently, the secondary recoil component due to the propellant gas is large
Implementation Method 3
multiple axial baffles, each of which reduces the pressure, velocity and temperature of the propellant gas before any remaining gas is ultimately exhausted down the suppressor bore

AI summary
A firearm suppressor with an integral muzzle brake that combines elements of muzzle brake, which comprises a plurality of radial/lateral ports that divert the high pressure propellant gas at an angle approximately perpendicular to the travel of the projectile thus reducing the recoil, with elements of a suppressor, which employs a plurality of axial baffles, each of which reduces the pressure, velocity and temperature of the propellant gas and before the gas is exhausted thus reducing the noise. Each individual axial stage has multiple subsequent radial/lateral chambers such that each axial stage has elements of a complete suppressor. Multiple expansion chambers each have an orifice connecting one expansion chamber to the next, and eventually vents to the external atmosphere. The exhaust port vents to the atmosphere and is directed radially or can be directed rearward to even further reduce the recoil in a similar fashion to a muzzle brake.
