RPG Disruption System Intercepting Warheads via Conductive Bar
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current protection systems for enclosures against Rocket Propelled Grenades (RPGs) are ineffective in preventing the initiation of the explosive material before impact, as they primarily rely on deflecting or disrupting the kinetic energy after the projectile has struck, rather than neutralizing the threat before detonation.
Innovation Solution
The RPG Disruption System (RDS) uses a casing with a propelling mechanism to deploy a disrupting element that intercepts and neutralizes the RPG by disrupting the electric initiation sequence, either by breaking or truncating the Piezo-electric sensor or causing an electric shortcut, thereby preventing the detonator from activating the explosive.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If reactive armor plates with explosive material are used to disrupt kinetic energy after impact, then protection against projectile impact is improved, but the system cannot prevent initiation of explosive material before impact
Solution Approach 1:
The patent applies preliminary action by detecting the incoming RPG threat before impact and pre-positioning the disrupting element (conductive bar) to intercept the projectile. The system uses sensors to detect the RPG launch and trajectory, then activates the propelling mechanism to deploy the disrupting element at the optimal position and timing to short-circuit the Piezo-electric sensor before the RPG can detonate upon impact.
Solution Approach 2:
The patent replaces the passive mechanical reactive armor system with an active electro-mechanical system. Instead of relying solely on explosive-reactive plates that respond after impact, the system uses electronic sensors to detect the threat, an electronic control system to process the detection signal, and a propelling mechanism (electromagnetic or pneumatic) to rapidly deploy the disrupting element. This substitution of mechanical with electro-mechanical systems enables timely prevention of explosive initiation.
2Reliability
If high-momentum disrupting elements are used to intercept RPGs, then neutralization effectiveness is improved, but the complexity and energy requirements of the propelling mechanism increase
Solution Approach 1:
The patent changes the key parameter of the disrupting element from high momentum to high electrical conductivity. Instead of using heavy, high-momentum projectiles that require complex and energy-intensive propelling mechanisms, the system uses lightweight conductive bars (made of materials like copper, aluminum, or galvanized steel) that can be propelled by simple electromagnetic or pneumatic mechanisms. The neutralization effectiveness is achieved through the electrical conductivity that creates a short-circuit in the Piezo-electric sensor, not through mechanical momentum.
