UAM Flight Plan Battery Management for Reachable Destinations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery management systems for UAM (Urban Air Mobility) aircraft struggle to determine whether a destination can be reached based on battery capacity, leading to potential accidents due to insufficient battery power.
Innovation Solution
A method for managing batteries in UAM aircraft involves calculating battery consumption based on flight plans, generating modified flight plans by adjusting for vertical and horizontal movement rates, and determining candidate destinations based on battery capacity, ensuring safe operation and efficient energy use.

Engineering Contradiction Analysis
1Duration of action of moving object
If battery capacity is increased to enable longer flight duration and greater destination reachability, then the aircraft can reach more distant destinations, but the battery weight increases which reduces energy efficiency
Solution Approach 1:
The system performs preliminary calculation of battery consumption for different flight scenarios before takeoff. It divides the flight path into vertical and horizontal segments, calculates required battery capacity for each segment, and determines the minimum battery capacity needed to reach the destination before the flight actually occurs. This allows optimal battery selection without excessive capacity.
Solution Approach 2:
The flight path is segmented into vertical movement portions (takeoff, climbing, landing) and horizontal movement portions. Each segment is analyzed separately for battery consumption characteristics, allowing precise calculation of total energy requirements without over-provisioning battery capacity.
2Measurement precision
If battery management system calculates detailed battery consumption for vertical and horizontal movement, then destination reachability accuracy improves, but system complexity increases
Solution Approach 1:
The battery management system segments battery consumption calculation into distinct vertical and horizontal movement components. By treating these movement types separately with different consumption coefficients, the system achieves precise destination reachability determination while maintaining manageable computational complexity through modular calculation approach.
