Integrated Engine And Flight Control With Unified Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional aircraft control systems suffer from inefficient feedback between independent control subsystems, hindering optimization of aircraft operation.
Innovation Solution
An aircraft control system with a single processor or set of processors that integrates and controls both engine and flight control subsystems, utilizing multiple processors and memory units to enhance coordination and redundancy, with direct interlinking and hub-based communication for efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple independent control subsystems are used for engine and flight control, then functional independence and reliability are improved, but feedback efficiency and coordination between subsystems deteriorate
Solution Approach 1:
The patent merges previously independent engine control and flight control subsystems into a unified control architecture where a single processor executes integrated control algorithms for both subsystems, eliminating inter-subsystem feedback delays and improving coordination efficiency
2Productivity
If a single integrated processor controls both engine and flight control subsystems, then control efficiency and coordination are improved, but system complexity increases
Solution Approach 1:
The patent segments the control system into distinct control channels (first and second control channels) that are directly linked to the processor, allowing independent processing of engine and flight control functions while maintaining unified coordination through the single processor architecture
3Reliability
If redundant processors and memory units are added for failure scenarios, then system reliability is improved, but device complexity increases
Solution Approach 1:
The patent implements preemptive redundancy by configuring the processor with multiple directly linked control channels and memory units that can immediately take over in case of failure, providing fault tolerance before failures occur without requiring complex switch-overs or backup systems

AI summary
An aircraft control system may include an engine control subsystem, a flight control subsystem, a processor, and a tangible, non-transitory memory. The tangible, non-transitory memory may be configured to communicate with the processor, and the tangible, non-transitory memory may have instructions stored thereon that, in response to execution by the processor, cause the aircraft control system to perform various operations. The various operations may include controlling, by the processor, the engine control subsystem and controlling, by the processor, the flight control subsystem. That is, a single processor (or a single set of processors) may control both the engine control subsystem and the flight control subsystem.
