Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerial defense systems are inadequate for defending against invasive low-cost unmanned aerial vehicles (UAVs) due to high costs and impracticality, and they struggle to effectively intercept and incapacitate multiple fast-moving targets, especially when sensors and tracking systems are not suited for proximate and maneuverable threats.
Innovation Solution
A modular and cost-effective aerial defense system utilizing modified commercial off-the-shelf (COTS) UAVs equipped with improved communication and sensor payloads, along with a virtual reality simulation system for training and testing, to generate a realistic aerial simulation environment, allowing for efficient tracking and neutralization of multiple targets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional anti-aircraft systems (missiles or guns) are used to defend against invasive UAVs, then the defensive capability is improved, but the cost becomes prohibitively expensive
Solution Approach 1:
The patent employs disposable COTS UAVs as defensive weapons instead of expensive traditional anti-aircraft systems. These low-cost defensive UAVs are designed to be consumed in single-use missions, where they intercept and neutralize target UAVs, then are discarded. This approach makes the defensive system cost-effective by replacing prohibitively expensive missiles and guns with inexpensive disposable drones.
Solution Approach 2:
The patent creates a copy of the target UAV platform by using similar COTS UAV technology for both offensive and defensive purposes. By copying the design and technology of the threat platform, the defensive system achieves cost parity with the target while maintaining the ability to effectively intercept and neutralize the same type of aircraft.
2Ease of manufacture
If tube-launched small UAS systems are used for defense, then the cost is reduced, but the speed and maneuverability decrease due to tube sizing requirements
Solution Approach 1:
The patent extracts the defensive UAVs from tube launchers and enables them to operate independently as free-flying aircraft. By removing the tube launch constraint, the defensive UAVs achieve full maneuverability and speed capabilities without being limited by tube diameter requirements, while still maintaining low costs through COTS technology.
Solution Approach 2:
The patent employs dynamically controllable COTS UAVs with adjustable flight characteristics that can adapt to different mission requirements. These UAVs possess full flight control surfaces and can dynamically adjust their speed, altitude, and maneuverability during interception missions, unlike rigid tube-launched systems with fixed trajectories.
3Measurement precision
If traditional sensor systems are used for tracking, then the system is suitable for distant targets, but it fails to effectively track proximate fast-moving objects
Solution Approach 1:
The patent employs dynamic sensor systems with high refresh rates and adjustable field of view that can adapt to both distant and proximate targets. The sensor payload includes cameras and detectors with electronic zoom and tracking capabilities that maintain measurement precision whether the target is far away or in close proximity, unlike fixed mechanical gimbal systems.
Solution Approach 2:
The patent creates a universal sensor system that can effectively track targets at all ranges from distant to proximate. The sensor payload is designed to handle both long-range detection and short-range high-speed tracking through electronic controls and image processing, eliminating the need for separate sensor systems for different target ranges.
4Reliability
If experimental flight testing is conducted to develop and evaluate autonomous aerial systems, then the system reliability is improved, but the time and technical risks increase
Solution Approach 1:
The patent implements comprehensive virtual reality simulation testing before actual flight tests. The simulation environment models various flight scenarios, weather conditions, and target behaviors to pre-validate autonomous algorithms and system performance. This preliminary virtual testing identifies and resolves issues before physical flight, reducing the time and risks associated with experimental flight testing.
Solution Approach 2:
The patent introduces a virtual reality simulation environment as an intermediary between theoretical development and physical flight testing. This intermediate testing layer allows thorough evaluation of autonomous systems in a controlled virtual setting, reducing the number of high-risk flight hours needed while maintaining system reliability through extensive virtual validation.
