Firearm Noise Suppressor with Multi-Chamber Gas Expansion

Solution Overview

Problem

Existing firearm noise suppressors for shotguns are not optimized for noise attenuation and heat dissipation, leading to inefficiencies in reducing muzzle noise and managing heat effectively.

Innovation Solution

The proposed suppressor system includes an inner sleeve surrounding the firearm barrel, an outer sleeve surrounding both the barrel and the inner sleeve, and a plurality of barrel and inner sleeve openings that allow gases to expand and interact, creating interference areas that attenuate noise. This configuration also includes dividers that direct gas expansion and control sound waves, enhancing noise reduction and heat dissipation.

Solution Approach 1:

The suppressor is divided into multiple chambers (first chamber, second chamber, third chamber) with distinct functions. The first chamber handles initial gas expansion, the second chamber creates interference areas for noise attenuation, and the third chamber provides additional expansion space. This segmentation allows each chamber to be optimized for specific tasks, improving overall noise attenuation and heat dissipation efficiency.

AI summary

A suppressor system for a firearm having aligned sleeve openings between the barrel or a central tube and an inner sleeve. The suppressor system further includes dividers located between an outer sleeve and the inner sleeve. The suppressor system provides improved noise attenuation through the expansion of hot gasses multiple cavities in the suppressor system and also by slowing the hot gasses via tortuous pathways or collision of hot gasses in the suppressor system.
