Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Determining permissible flight boundaries for aircraft is challenging due to the numerous factors that need consideration, including pilot identity, experience, and environmental conditions, which can lead to pilot error and inexperience.
Innovation Solution
A flight controller system that determines flight boundaries based on aircraft-specific data, including pilot identity and experience, generates movement limits, and generates control signals to maintain these boundaries using a thrust envelope, incorporating sensors and a propulsor component to control aircraft movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flight boundaries are determined considering multiple factors (pilot identity, experience, environmental conditions), then safety and precision are improved, but system complexity increases
Solution Approach 1:
The system segments the flight boundary determination into distinct modules: a flight boundary determination module that processes multiple factors (pilot identity, experience, environmental conditions) to establish initial boundaries, and a movement limit setting module that applies specific limit values. This segmentation allows complex safety considerations to be handled in organized, manageable sections without overwhelming the overall system.
Solution Approach 2:
The flight controller acts as an intermediary between the pilot control system and the aircraft propulsion system. It receives thrust envelope instructions from the pilot control, processes them through flight boundary determination algorithms that consider multiple safety factors, and generates appropriate control signals. This intermediary role manages system complexity by centralizing the decision-making logic in a dedicated controller that coordinates all safety-related operations.
2Reliability
If flight boundaries are strictly controlled to prevent pilot error, then safety is improved, but operational flexibility deteriorates
Solution Approach 1:
The system implements dynamic flight boundary adjustment by allowing the flight controller to modify movement limits and thrust envelope parameters in real-time based on current flight conditions, pilot inputs, and environmental factors. The flight boundary determination module continuously updates permissible flight regions, enabling the system to maintain strict safety control while adapting to changing operational requirements throughout the flight.
Solution Approach 2:
The system changes key parameters such as thrust envelope limits, speed restrictions, and altitude boundaries dynamically during flight. The flight controller adjusts these parameters based on the aircraft's current state, pilot experience level, and environmental conditions, allowing strict safety control through parameter management while maintaining operational flexibility through continuous parameter adaptation.
3Productivity
If real-time updates to flight boundaries are implemented, then operational efficiency is improved, but computational requirements and system complexity increase
Solution Approach 1:
The flight boundary determination module performs preliminary calculations of permissible flight boundaries before critical flight phases occur. By pre-determining safe flight regions based on pilot credentials, aircraft performance data, and forecasted environmental conditions, the system reduces real-time computational requirements while maintaining operational efficiency during actual flight execution.
Solution Approach 2:
The system implements continuous feedback loops where the flight controller monitors actual flight parameters, compares them against determined flight boundaries, and generates corrective control signals when approaching limits. This feedback mechanism enables real-time operational efficiency by automatically adjusting control inputs based on boundary constraints, reducing the need for complex real-time recalculation while maintaining strict adherence to safety boundaries.
