Blast Attenuator with Shear Thickening Fluid Core

The patent employs a porous foam material as the core structure of the blast attenuator. This porous material provides high energy absorption capacity through its cellular structure, allowing the vehicle to achieve effective blast protection with significantly reduced weight compared to conventional solid armor designs.

The invention uses a composite structure combining porous foam material with a shear thickening fluid. The foam provides structural framework and volume, while the fluid provides dynamic energy dissipation during blast events. This composite approach achieves superior protection-to-weight ratio compared to traditional homogeneous materials.

The porous foam core provides high specific energy absorption, enabling the blast attenuator to protect against explosive devices while maintaining a compact, lightweight form factor that preserves vehicle agility and transportability in tactical operations.

The shear thickening fluid changes its viscosity parameters dynamically in response to blast loading. The fluid remains low-viscosity during normal operation, maintaining vehicle mobility, and rapidly increases viscosity when subjected to blast forces, providing protective reinforcement only when needed.

The porous foam core can be manufactured using cost-effective industrial foam fabrication processes, avoiding the need for expensive precision metalworking or complex assembly operations. The open-cell structure is formed in a single manufacturing step, reducing production complexity and cost.

The blast attenuator is designed as a disposable or replaceable component that can be easily manufactured at low cost and installed on vehicles. The relatively simple construction using foam and fluid allows for economical production and potential replacement if degraded or damaged.
