Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for collecting and displaying test flight data are cumbersome, costly, and inefficient, particularly due to the need for extensive equipment and static data recording, which limits the ability to dynamically select and analyze data in real-time on aircraft.
Innovation Solution
A method and system that dynamically selects and retrieves real-time data from a flight computer's main memory using a memory read-out device with a standard interface, allowing for in-flight reprogramming and minimal hardware requirements, enabling real-time data collection and analysis via serial data busses or radio telemetry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional flight test data collection systems are used, then data can be recorded, but the equipment is cumbersome, costly, and requires large physical space
Solution Approach 1:
The patent extracts the data collection functionality from traditional cumbersome flight test equipment and relocates it directly into the aircraft's existing flight computer system. By utilizing the flight computer's built-in memory and processing capabilities, the system eliminates the need for separate external recording equipment, thereby reducing device complexity while maintaining data collection reliability
Solution Approach 2:
The patent makes the flight computer serve multiple functions: it acts as both the flight control system and the data collection/analysis system. By programming the flight computer to collect, store, and analyze test data in addition to its primary flight control functions, the system eliminates the need for dedicated separate equipment, reducing overall system complexity and cost
2Reliability
If preprogrammed flight test data systems are used, then data collection is possible, but the system is static and requires re-flying to change parameters
Solution Approach 1:
The patent transforms the static, preprogrammed data collection system into a dynamic one by enabling real-time parameter selection and configuration. The system allows operators to modify data collection parameters, memory addresses, and analysis settings during flight operations, providing adaptability and versatility while maintaining reliable data collection
Solution Approach 2:
The patent implements a feedback mechanism where the system continuously monitors flight parameters and allows dynamic adjustment of data collection settings based on real-time conditions. This feedback loop enables the system to adapt to changing test requirements during flight without requiring re-flying, enhancing both versatility and operational efficiency
3Quantity of substance
If extensive flight test equipment is deployed, then comprehensive data can be collected, but the hardware is costly and space-consuming
Solution Approach 1:
The patent merges the data collection, storage, and analysis functions with the aircraft's existing flight computer system. By combining these functions into a single integrated system rather than using separate external equipment, the patent achieves comprehensive data collection capabilities while minimizing additional hardware weight and space requirements
Solution Approach 2:
The patent utilizes the flight computer's existing memory and processing resources to store and analyze test data, effectively copying the data collection functionality into the existing system rather than adding separate physical storage and processing equipment. This approach maintains comprehensive data collection while avoiding the weight and cost of duplicate hardware
Data Source
AI summary
A method and system for dynamically selecting and retrieving real-time data from a time/space partitioned flight computer system located on board an aircraft. The system used to implement this method consists of an on-board memory read-out device attached to a serial data bus capable of communicating with the flight computer and/or a ground-based memory read-out device capable of communicating with the flight computer via radio telemetry. This data consists of any valid memory location within the flight computer, including but not limited to flight data, aircraft status, and flight computer state.
