Solution Overview

Problem

Current active protection systems for aerial platforms against rocket-propelled grenades and other aerial threats are either too heavy, bulky, or ineffective for platforms with weight and size constraints, and lack the ability to coordinate multiple engagements and avoid fratricide or collateral damage.

Innovation Solution

A lightweight, portable active kinetic countermeasure system that includes a guided eject vehicle launched from a conventional dispenser, using radar modules for detection, tracking, and guidance to intercept and destroy aerial threats, with the ability to coordinate with other platforms to prevent damage to friendly forces and civilians.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional active protection systems are installed on aerial platforms, then protection against RPG attacks is improved, but weight and size constraints are violated

Engineering Contradiction:
Improveprotection effectivenessVSAvoidsystem weight
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

The system divides the protection function into separate modular components: radar modules for detection, a lightweight eject vehicle for interception, and a control system for coordination. Each module is independently optimized for minimal weight while maintaining effectiveness, allowing the overall system to meet aerial platform constraints.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A lightweight eject vehicle serves as an intermediary between the aerial platform and incoming RPG threats. This intermediate interceptor destroys threats at a distance from the platform, eliminating the need for heavy armor or large-scale active protection systems while maintaining 90% success rate at close ranges.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Area of stationary object

If multiple engagement systems operate simultaneously, then coverage area is improved, but fratricide and collateral damage increase

Engineering Contradiction:
Improvecoverage areaVSAvoidcollateral damage
Core Design Contradiction:
Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The system incorporates real-time feedback mechanisms where radar modules continuously monitor the electromagnetic environment, detect friendly platform signatures, and communicate threat locations to adjacent systems. This feedback loop enables dynamic coordination that prevents fratricide while maintaining comprehensive coverage.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

Multiple engagement management systems are merged into a coordinated network that shares radar data and threat information. By combining detection capabilities and coordinating intercept decisions across platforms, the system achieves expanded coverage while minimizing collateral damage through unified engagement control.

Inventive Principle:
Principle #5Merging (Combining)
