Modular Insert Barrel for Multi-Caliber Disrupter Cannon
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Disrupter cannons face limitations in supporting projectiles and cartridges of different calibers and achieving a wider range of operation, which can affect their effectiveness in disabling explosive devices.
Innovation Solution
The design incorporates an insertable barrel system that allows for the use of various calibers, including 12-gauge shotgun shells, .380 ACP, and 45 ACP, with a modular breech cap and firing assembly that can handle different cartridges, and a tripod-mounted system for stable positioning and recoil management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed barrel design is used, then the structure is simple, but the cannon cannot support projectiles and cartridges of different calibers
Solution Approach 1:
The barrel is divided into a main barrel and a removable insert barrel. The insert barrel can be removed and replaced to change the caliber, allowing the system to support multiple projectile types without redesigning the entire cannon structure.
Solution Approach 2:
The main barrel is designed with a universal interface that can accommodate multiple types of insert barrels for different calibers (12-gauge, .380 ACP, 45 ACP). This allows a single cannon platform to perform multiple functions by simply changing the insert barrel.
2Adaptability or versatility
If a modular insertable barrel system is used, then the cannon can support various calibers, but the device complexity increases
Solution Approach 1:
The barrel system is segmented into a main barrel and interchangeable insert barrels. Each insert barrel is designed with specific features (such as recesses and protrusions) that enable easy insertion and removal, reducing the complexity of switching between calibers despite the modular design.
3Length of stationary object
If the range of operation is increased, then the effectiveness against explosive devices improves, but the recoil management becomes more challenging
Solution Approach 1:
The tripod is configured to support the disrupter cannon at various positions and angles, providing stability and counteracting recoil forces. The tripod's structure acts as a counterbalance to the recoil impulse, allowing the cannon to achieve greater range while maintaining control and accuracy.
4Productivity
If rapid reloading is enabled, then the productivity increases, but the ease of operation for different calibers may be reduced
Solution Approach 1:
The barrel system is segmented into a main barrel and removable insert barrels. The insert barrels are designed with standardized interfaces and features (such as recesses and protrusions) that enable quick insertion and removal, allowing rapid reloading while maintaining ease of operation across different calibers.
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
Enables the disrupter cannon to accurately and effectively launch projectiles of different calibers over a greater range, enhancing its capability to disable explosive devices without triggering them, while maintaining ease of use and rapid reloading.
Implementation Method 1
The pyrotechnic that generates the rapidly expanding gas used to propel a projectile is generally held in the cartridge
Implementation Method 2
The shock tube includes a firing pin and a shock tube bore. The shock tube bore is configured to receive a shock tube cartridge having a pyrotechnic coating on an interior surface of the shock tube bore
Implementation Method 3
A seal may be positioned in channel 364. The seal may establish a seal between the cartridge and the barrel

AI summary
A disrupter cannon includes a barrel for launching a projectile. An insert may be used to launch a projectile of a smaller diameter than the projectile launched through the barrel of the disrupter cannon. An insert includes a bore therethrough, a breech-end portion, and a muzzle-end portion. The breech-end portion includes a channel. An O-ring is positioned in the channel of the breech-end portion. The muzzle-end portion includes one or more channels. A respective O-ring is positioned in each channel of the muzzle-end portion. While the insert is positioned in the barrel, the O-rings are configured to form a seal between an outer surface of the insert and an inner surface of the barrel. The projectile with a smaller diameter is launched through the bore of the insert.
