Flight Restriction Setting System for Aircraft Damage Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems fail to effectively set appropriate flight restrictions for an aircraft based on the degree and location of damage to its structure, often imposing excessive restrictions even when structural members have strength margins, leading to unnecessary limitations on altitude, speed, and load factor.
Innovation Solution
A flight restriction setting system that includes a damage detector and a flight restriction calculator, which detects damage and sets restrictions based on the degree and location of damage, using sensors and signal processing to determine allowable internal and external loads, and generates a V-n diagram to define safe flight conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flight restriction is imposed based on conservative safety assumptions, then safety is improved, but flight performance and operational flexibility deteriorate due to excessive restrictions
Solution Approach 1:
The system applies local quality by assessing damage specifically at the damaged location and calculating restrictions only for structural members affected by the damage. Instead of imposing uniform flight restrictions across the entire aircraft, the system identifies which specific structural members have reduced strength margins and calculates allowable loads only for those members, allowing other unaffected members to operate at their full capacity.
Solution Approach 2:
The system changes parameters by dynamically calculating allowable internal and external loads based on the specific damage characteristics (location, extent, type). The flight restriction calculator adjusts structural strength parameters, load factors, and maneuvering envelope parameters according to the actual damage condition, rather than applying fixed conservative restrictions. This allows the aircraft to operate with optimized flight conditions matched to the actual structural state.
2Reliability
If uniform flight restriction is applied across all structural members, then safety is simplified to ensure, but unnecessary restrictions are imposed on members with sufficient strength margins
Solution Approach 1:
The system implements local quality by evaluating each structural member's strength margin individually based on its specific damage condition. The flight restriction calculator determines allowable loads for each member separately, allowing members without damage or with sufficient strength margins to operate without restriction while applying restrictions only to damaged members. This localized approach replaces uniform restrictions with differentiated, member-specific operating conditions.
Solution Approach 2:
The system applies segmentation by dividing the aircraft structure into individual members and assessing each member's damage condition and strength margin separately. The flight restriction calculator processes each structural member independently, calculating allowable internal and external loads for each member based on its specific damage characteristics, rather than applying a single uniform restriction to the entire aircraft structure.
3Productivity
If detailed damage assessment and individualized flight restriction calculation are implemented, then operational flexibility is improved, but system complexity increases
Solution Approach 1:
The system applies self-service by enabling the aircraft's own flight control system to automatically assess damage conditions and calculate appropriate flight restrictions using onboard sensors and the flight restriction calculator. The system serves itself by autonomously determining allowable loads and generating updated maneuvering envelopes without requiring external expert intervention, reducing the complexity burden on operators while maintaining detailed assessment capabilities.
Solution Approach 2:
The system implements preliminary action by pre-calculating and storing the relationship between damage characteristics and allowable loads for various structural members. The flight restriction calculator uses pre-established methods and formulas to quickly determine flight restrictions based on detected damage, avoiding the need for complex real-time analysis during critical post-damage situations. This preliminary preparation simplifies the operational complexity while maintaining detailed assessment accuracy.
