Non-initiating Tandem Warhead Powder Jet Precursor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tandem warheads struggle to effectively penetrate tanks equipped with advanced explosive reactive armor, as the precursor's conventional penetrator leaves behind residue, reducing the penetration capability of the main warhead jet.
Innovation Solution
A non-initiating tandem warhead with a precursor forming a low-density powder jet using a metal powder-based powder jet formation liner, which creates a penetration hole in the explosive reactive armor without detonating it, allowing the main warhead to pass through unimpeded and leaving no residue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional penetrator is used in the precursor to penetrate the explosive reactive armor, then the penetration hole is created, but residue is left behind that reduces the penetration capability of the main warhead jet
Solution Approach 1:
The patent changes the physical state and density parameters of the jet material by using powder form instead of solid penetrator. The powder jet has lower density and leaves no residue, fundamentally altering how the precursor interacts with the explosive reactive armor while maintaining penetration capability.
Solution Approach 2:
The powder jet formation liner is designed to be consumed during the interaction with explosive reactive armor, forming a powder jet that dissipates without leaving harmful residue. This disposable approach ensures the precursor completes its function of creating a penetration path without compromising the main warhead's performance.
2Reliability
If the precursor detonates the explosive reactive armor to eliminate it, then the armor is removed, but the main warhead jet loses penetration capability due to the detonation impact
Solution Approach 1:
The powder jet acts as an intermediary that interacts with the explosive reactive armor without causing detonation. It creates a penetration hole through controlled erosion and mechanical action, serving as a mediator that removes the armor's protective function without triggering its explosive response.
Solution Approach 2:
The patent converts the harmful effect of explosive reactive armor (its ability to detonate and disrupt jets) into a benefit by avoiding detonation altogether. The powder jet's low density and non-detonating interaction allow the precursor to neutralize the armor's protective function while preserving the main warhead jet's penetration capability.
3Strength
If thick steel plates are used in explosive reactive armor to disrupt the main warhead jet, then the protective capability is enhanced, but the precursor cannot fully eliminate the explosive reactive armor
Solution Approach 1:
The patent changes the interaction parameters by using a powder jet with lower density and different mechanical properties compared to conventional solid penetrators. This allows the precursor to effectively interact with and create penetration holes in thick steel plates without triggering detonation, maintaining reliability against enhanced armor protection.

AI summary
The present invention relates to a tandem warhead including a precursor neutralizing an explosive reactive armor, which is an additional armor of tanks, without detonating it and a main warhead configured to destroy a main armor, and more particularly to a non-initiating tandem warhead with a precursor forming powder jet against the explosive reactive armor, the powder jet leaving behind no residue of the precursor jet to maximize the penetration capability of the main warhead jet.
