Radar-Absorbing Projectile With Discarding Protective Carrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional projectiles are difficult to penetrate defensive nets due to radar detection and tracking, exposing stealth vehicles to counter-battery fire, and existing stealth technologies fail to maintain radar-absorbing materials during launch.
Innovation Solution
A projectile design featuring an exterior layer of radar-absorbing material covered by a carrier that detaches post-launch, ensuring the material remains intact and reduces radar observability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If radar-absorbing material is applied directly to the projectile surface, then radar observability is reduced, but the material is scraped off during contact with the artillery bore
Solution Approach 1:
The projectile system is divided into two functional segments: a protective carrier that interfaces with the artillery bore and a projectile core with radar-absorbing material that provides stealth capabilities. The carrier acts as a sacrificial protective layer that prevents damage to the RAM during launch, then separates from the projectile after firing, allowing the RAM to remain intact and functional throughout flight.
Solution Approach 2:
A carrier serves as an intermediary component between the artillery bore and the radar-absorbing material. This carrier protects the RAM from direct contact with the bore during launch, preventing contamination or damage. After firing, the carrier detaches, leaving the clean, intact RAM-coated projectile to execute its stealth function without interference.
2Reliability
If a carrier protects the radar-absorbing material during launch, then material integrity is maintained, but the carrier must detach and fall away after firing
Solution Approach 1:
The carrier is designed as a temporary, discarding component that fulfills its protective function during launch and then intentionally separates from the projectile. This allows the complex protection mechanism to be shed after use, leaving only the simple, lightweight projectile with intact RAM coating for the flight phase, optimizing both protection and performance.
3Device complexity
If conventional projectiles are used, then simplicity is maintained, but radar detection and tracking expose the launch platform to counter-battery fire
Solution Approach 1:
The projectile employs localized radar-absorbing material coating on its exterior surface, providing stealth capabilities only where needed for radar detection reduction. This selective application of special material properties allows the projectile to maintain conventional simple structure in non-critical areas while incorporating advanced RAM technology in the critical exterior surface area where radar interaction occurs.

Function Achieved in This Case
The design enhances the projectile's ability to penetrate defensive nets and reduces the likelihood of tracking back to the launch platform, maintaining stealth capabilities.

AI summary
A radar-absorbing material projectile system including a projectile with an outer layer of radar-absorbing material (RAM). A carrier or armature is disposed around the projectile, protecting the layer of RAM during the firing sequence. In some embodiments the carrier is a discarding carrier which falls away after firing, rendering the projectile low-observable with regard to radar detection due to the layer of RAM.
