Tethered UAV Power and Data Link for Extended Flight
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned aerial vehicles (UAVs) face limitations in extended flight time and restricted mission areas due to battery power, and existing power extension methods are not universally effective.
Innovation Solution
The Persistent Aerial Reconnaissance and Communication (PARC) System employs a microfilament tether that transmits over a kilowatt of power and enables bi-directional data and high-definition video transmission, allowing for extended flight times and simplified deployment in austere environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If battery power is used to power the UAV, then the UAV can operate autonomously, but the flight time is limited by battery capacity
Solution Approach 1:
A ground-based power station serves as an intermediary to supply power to the UAV through a microfilament tether, extending flight time beyond battery limitations while maintaining autonomous operation. The power station acts as an external energy reservoir that connects to the moving UAV through the tether medium.
2Duration of action of moving object
If a microfilament is deployed from ground location to extend power, then flight time is extended, but the mission flight area is restricted by filament length
Solution Approach 1:
The microfilament tether system is designed to be dynamic and extensible, allowing the UAV to operate at varying distances from the ground station. The tether can be deployed or retracted as needed, enabling the flight area to adapt to mission requirements while maintaining power connection.
3Duration of action of moving object
If traditional tether systems are used, then power can be supplied for extended duration, but operator management and logistics requirements increase
Solution Approach 1:
The UAV system incorporates autonomous tether management capabilities, including automated deployment, retraction, and tension control. The microfilament tether system is designed to self-regulate during flight operations, reducing the need for continuous operator intervention and minimizing logistics requirements.
