Missile Launch Container Shock Damping via Breakable Threshold Bars
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing missile launch container systems on ships transmit shocks fully to the ammunition, such as those from underwater explosions, leading to potential damage due to inadequate protection.
Innovation Solution
The missile launch container is designed with axial and lateral movement control in the well, featuring centering/guiding means and a shock filtration threshold with damping assemblies comprising metal coils and breakable bars, which absorb and filter shock energies to protect the ammunition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the launch container is rigidly fixed to the well bottom, then the container is stable and positioned correctly, but shocks from underwater explosions are transmitted entirely to the ammunition
Solution Approach 1:
The patent applies beforehand cushioning by installing shock-filtering threshold damping means between the container sole and ship support sole before shocks occur. These damping means include metal coil assemblies and breakable threshold bars that are pre-positioned to absorb and filter shock energies during underwater explosions, preventing direct transmission to the ammunition while maintaining container stability during normal operation
Solution Approach 2:
The patent applies parameter changes by using damping materials with specific viscoelastic properties that change their energy absorption characteristics based on shock intensity. The damping means are designed to remain rigid under normal conditions for stability, but transition to energy-absorbing modes during shock events, dynamically adjusting the system's mechanical properties to protect ammunition
2Object-affected harmful factors
If shock-filtering damping means are added between the container and ship structure, then ammunition protection is improved, but the device complexity increases
Solution Approach 1:
The patent applies merging by combining multiple shock protection functions into an integrated assembly. The damping means include metal coil assemblies and breakable threshold bars that work together as a unified system, with the coils providing primary shock absorption and the threshold bars providing secondary protection and structural linkage, reducing the need for separate complex components
Solution Approach 2:
The patent applies the disposable principle by incorporating breakable threshold bars that are designed to fail in a controlled manner during extreme shocks, sacrificing these relatively simple components to protect the valuable ammunition. After use, these bars can be replaced without replacing the entire complex damping system, reducing overall system complexity and cost

Function Achieved in This Case
This solution effectively reduces the acceleration of ammunition during shocks, limiting damage and allowing for the reuse of the launcher after an event by reconfiguring the broken components, thus enhancing the protection and operational resilience of the system.
