Tandem Charge Shock Wave Deflection Cap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tandem charges for missiles face challenges in shock wave management, which can compromise the performance and safety of the main charge due to the coupling of shock waves into the envelope, particularly in penetrator tips where geometric changes are not feasible.
Innovation Solution
A shock-resistant cap is applied to the tip of the main charge's shell, designed to deflect shock waves with optimized geometry and material selection, reducing shock wave transmission into the envelope and allowing the penetrator tip to maintain its original shape and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the penetrator tip is designed with a specific geometry for penetration performance, then penetration effectiveness is improved, but shock wave rejection capability deteriorates
Solution Approach 1:
The tip region is segmented into two functional parts: the original penetrator tip geometry (for penetration) and the added cap structure (for shock wave rejection). This segmentation allows each part to be optimized independently for its specific function without compromising the other.
Solution Approach 2:
The cap acts as an intermediary element between the shock wave and the penetrator tip. It receives the shock wave and deflects it away from the tip, preventing direct coupling while allowing the tip to maintain its penetration-optimized geometry.
2Object-affected harmful factors
If the tip geometry is modified to reduce shock wave transmission, then shock properties are improved, but penetration performance deteriorates
Solution Approach 1:
The tip is divided into the original penetrator section (maintaining penetration geometry) and the added cap (providing shock wave deflection). This allows the penetration function to remain unchanged while the shock wave protection is added through the cap structure.
Solution Approach 2:
The cap serves as an intermediary that handles shock wave interaction, preventing the need to modify the penetrator tip geometry. It mediates between the incoming shock wave and the tip, absorbing and deflecting the shock while allowing the tip to maintain its optimized penetration shape.
3Object-affected harmful factors
If a protective hood is added to surround the main charge, then shock wave protection is improved, but device complexity and space requirements worsen
Solution Approach 1:
Instead of providing comprehensive shock wave protection through a full protective hood, the invention applies shock wave rejection capability locally at the tip region where shock coupling is most critical. This localized approach provides necessary protection while minimizing added complexity and space requirements.
Solution Approach 2:
The protective function is segmented from the main charge structure by adding a separate cap element only at the tip. This modular approach provides shock wave protection where needed without requiring a complete redesign of the entire charge structure.
