ICWS Periscope Transparent Armor Projectile Deflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Integrated Commander's Weapon Sight (ICWS) Periscopes face issues with leakage affecting visibility and safety due to air gaps and the inadequacy of glass in handling high-velocity projectiles, leading to potential penetration of projectile fragments into armored vehicles.
Innovation Solution
The design incorporates a stack of ballistic-tested glass to deflect projectiles, removes air gaps, and uses a high-grade metallic band and armored plate to redirect energy and protect the viewing area, ensuring safety and maintaining visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an air gap is positioned between the laser filter and the bottom block to reduce shock transfer, then the protection against projectile fragments is improved, but the leakage prevention deteriorates causing visibility reduction
Solution Approach 1:
The invention removes the air gap entirely from the periscope assembly, extracting the problematic element that caused leakage while maintaining protection through alternative means (ballistic glass and sealing structures)
Solution Approach 2:
The invention uses composite material structures, specifically ballistic glass blocks with integrated sealing properties, combining optical transparency with projectile resistance and leak prevention in a single material system
2Illumination intensity
If glass blocks are used to form the top and bottom blocks, then the optical performance is improved, but the safety against high velocity projectiles deteriorates
Solution Approach 1:
The invention employs ballistic glass, a composite material that combines the optical properties of glass with enhanced strength and projectile resistance through specialized material composition and layering structures
Solution Approach 2:
The invention changes the material parameters of the glass blocks by using ballistic-tested glass with modified composition and structure, transforming ordinary glass into a material that can withstand high-velocity projectiles while maintaining optical clarity
3Object-affected harmful factors
If the armored plate is used to prevent projectile fragments from penetrating, then the safety is improved, but the visibility and optical performance deteriorate
Solution Approach 1:
The invention replaces opaque armored plates with transparent ballistic glass blocks that provide equivalent or superior protection while maintaining optical transparency, allowing simultaneous achievement of safety and visibility
Solution Approach 2:
The invention uses multiple stacked glass blocks that replicate and distribute the protective function across several layers, with each block contributing to projectile deflection while maintaining overall optical transparency
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enhances the safety and optical performance of the periscope by preventing projectile penetration and maintaining a clear field of view, even under high-velocity impacts, by redirecting projectiles away from the interior and using transparent armor to absorb and deflect energy.
Implementation Method 1
at least one layer of transparent armor filling the space therebetween parallel to the field of view to deflect incoming projectiles from striking the object viewing section
Implementation Method 2
The top block serves as the entry point for the external incoming image. It has a mirrored back face that reflects the image
Implementation Method 3
a laser filter bonded to it with an optical adhesive to protect the commander from harmful wavelengths of light

AI summary
A periscope construction having a ballistic guard formed inside a protective housing, and optical system mounted therein having first and second blocks of optical material mounted at opposite ends; first and second reflective surfaces, and the object and eyepiece viewing surfaces of the respective blocks being generally parallel and forming a parallelogram in cross section; the first and second end surfaces being spaced from each other within the housing with at least one layer of transparent armor therebetween to deflect incoming projectiles away from the object viewing section; and may include at least one layer of transparent armor rigidly positioned at an angle relative to the field of view no less than 300° to a maximum of 360° which is parallel to the field of view. It may further include a high grade metallic band rigidly formed around and adjacent the space between the first and second end surfaces.
