Firearm Suppressor Baffles with Neck Port for Gas Disruption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm suppressors do not adequately reduce sound and flash escaping from the barrel, as high velocity expulsion of hot gases still produces significant noise and visibility.
Innovation Solution
The design incorporates baffles with a first cone portion, a second cone portion, and a neck with a reduced radius, where the port in the neck is positioned to disrupt gas flow, directing it through the passageway and reducing escape of sound and flash.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional suppressor baffles are used, then the suppressor structure is simple, but sound and flash suppression is insufficient
Solution Approach 1:
The baffle is divided into multiple functional segments: a first conical portion for initial gas direction, a neck portion with reduced radius for flow restriction, and a second conical portion for further gas management. This segmentation allows each portion to perform a specific function in the gas flow disruption process, enhancing suppression effectiveness while maintaining manufacturing feasibility through modular geometry
Solution Approach 2:
The neck portion is designed with a reduced radius specifically at the location where maximum gas flow disruption is needed. This local modification of the geometry creates a bottleneck effect that intensifies turbulence and enhances sound and flash suppression precisely where required, without unnecessarily complicating the entire baffle structure
2Object-affected harmful factors
If the neck radius is reduced to enhance suppression, then sound and flash reduction improves, but manufacturing precision requirements increase
Solution Approach 1:
The neck portion is designed with conical geometry rather than a sharp, abrupt reduction. This curved, tapered transition from the first to second conical portions allows for more tolerant manufacturing specifications while still achieving the desired flow restriction effect. The gradual geometric change is easier to manufacture with standard machining tolerances compared to sharp edges or abrupt radius changes

AI summary
Suppressors and baffles therein provide for sound and/or flash suppression of a firearm. The baffles include a first cone portion, a second cone portion, and a neck connecting the first cone portion and the second cone portion. The first cone portion and second cone portion define a passageway through which hot gases and a bullet may be expelled through and out of the suppressor. The first cone portion directs at least some expelled gases around the outer edge of the first cone portion and to the neck and second cone portion. The second cone portion together with a suppressor body block movement of the expelled gases. A port in the neck allows the expelled gases blocked by the second cone portion to escape toward the passageway to disrupt the flow of the expelled gases and thereby further suppress the sound and/or flash.
