Solution Overview
Problem
Existing systems face challenges in efficiently transferring engine data from aerial vehicle electronic engine controllers to a ground system, leading to difficulties in data availability and utilization.
Innovation Solution
A wireless communication unit is introduced that includes processors configured to receive and store engine data, with specific memory locations reserved for parameterized and streamed data, enabling communication via interfaces like TIA-485, and transmission to a ground system over a wireless network upon trigger conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual data retrieval is used, then system complexity is reduced, but data availability and transfer efficiency deteriorate
Solution Approach 1:
The wireless communication unit automatically retrieves and transfers engine data from the EEC to ground systems without requiring manual intervention. The system self-manages the data collection, packaging, and transmission processes, eliminating the need for manual data retrieval while maintaining operational simplicity through automated protocols
Solution Approach 2:
The wireless communication unit acts as an intermediary device between the EEC and ground systems. It receives data requests from ground systems, retrieves data from the EEC, and manages the transfer process, thereby automating data availability without significantly increasing overall system complexity
2Loss of information
If data is stored on EECs, then data source availability is improved, but ground system data accessibility deteriorates
Solution Approach 1:
The wireless communication unit serves as an intermediary that bridges the EEC and ground systems. It receives data from the EEC via standardized interfaces and makes it accessible to ground systems through wireless communication, thereby improving ground system accessibility without adding complex direct connection requirements
Solution Approach 2:
The data transfer system is segmented into distinct functional components: the EEC that generates data, the wireless communication unit that manages transfer, and the ground system that receives data. This segmentation allows each component to operate independently with well-defined interfaces, improving accessibility without proportionally increasing overall system complexity
