Adhesive Explosive Ring-Shaped Hollow Charge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adhesive charges with flat or pointed cone hollow charges have a high penetration depth but often result in a lower material discharge relative to their diameter, making them less effective on armored targets.
Innovation Solution
Incorporating a modular ring-shaped hollow charge with a V or U cross-section into the adhesive charge, initiated by a circular segment of explosives, which expands the damaged area upon detonation, compensating for reduced penetration depths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a flat or pointed cone hollow charge is used, then penetration depth is improved, but material discharge relative to diameter deteriorates
Solution Approach 1:
The invention transitions from a conical hollow charge that acts primarily in one dimension (depth) to a ring-shaped hollow charge that distributes explosive force across a two-dimensional area. The ring shape with V or U cross-section creates a circumferential cutting effect that increases material discharge in diameter while maintaining adequate penetration depth through the charged mass.
Solution Approach 2:
The invention changes the geometric parameters of the hollow charge from a cone shape to a ring shape with specific cross-sectional profiles (V or U shape). This parameter change fundamentally alters the stress distribution and material removal pattern, enabling simultaneous achievement of penetration and wide material discharge.
2Quantity of substance
If a ring-shaped hollow charge is used, then material discharge in diameter is improved, but penetration depth deteriorates
Solution Approach 1:
The ring-shaped hollow charge is nested within or integrated with the adhesive charge body. The charged mass is positioned to engage with the ring structure, allowing the explosive energy to be transmitted through the ring to achieve both circumferential material discharge and depth penetration through coordinated action of the nested components.
Solution Approach 2:
The invention combines the ring-shaped hollow charge structure with adhesive charge material in a composite configuration. The charged mass works in conjunction with the ring geometry to produce a combined effect that achieves both wide material discharge and sufficient penetration, compensating for the inherent limitations of the ring shape alone.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Implementation Method 2
Incorporating a modular ring-shaped hollow charge with a V or U cross-section into the adhesive charge, initiated by a circular segment of explosives, which expands the damaged area upon detonation

AI summary
The adhesive explosive (10) has an ignition device with a modular body (1) merged at a lower end of the adhesive explosive, where the modular body comprises an explosive substance (2) and a circular hollow explosive insert (3). The insert exhibits a V or U cross section. A projection (4) is provided in the explosive substance to transfer shock waves to a primary charge. The hollow explosive insert is made of copper or crystal glass, where the adhesive explosive is located above or on an armored target medium. USE : Adhesive explosive i.e. hand grenade (claimed) for use in a limpet mine. ADVANTAGE : The modular body is merged at the lower end of the adhesive explosive such that the adhesive explosive applies sufficient and deep force on the armored target medium, and the explosive substance can be directly loaded into the modular body. The design of the adhesive explosive allows introduction of additional hollow explosive substances.
