Solution Overview
Problem
The transition of electric vertical takeoff and landing (eVTOL) aircraft from vertical to horizontal flight is complex and poses safety challenges for pilots due to the different flight modes involved, necessitating a smoother and safer transition mechanism.
Innovation Solution
A system comprising a fuselage, laterally extending elements, and propulsors that can rotate between lift and thrust positions, controlled by a flight controller to autonomously identify and execute the transition point, ensuring a smooth transition from vertical to horizontal flight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If autonomous transition system is implemented, then pilot safety is improved, but device complexity increases
Solution Approach 1:
The flight controller autonomously identifies the flight transition point and controls the rotation of propulsors without requiring manual pilot intervention. The system monitors flight parameters, determines when transition conditions are met, and executes the rotation sequence automatically, allowing the aircraft to self-manage the complex transition process while the pilot maintains oversight through the override switch.
2Adaptability or versatility
If propulsors rotate between lift and thrust positions, then flight mode transition is improved, but ease of operation deteriorates
Solution Approach 1:
The flight controller continuously monitors flight parameters and automatically determines when transition conditions are satisfied. The system provides feedback-based autonomous control by comparing actual flight state with transition criteria, executing rotation when conditions are met, and allowing pilot override only when explicitly commanded through the override switch, thereby simplifying operation while maintaining transition capability.
3Use of energy by moving object
If automated flight transition is implemented, then energy management efficiency is improved, but manufacturing complexity increases
Solution Approach 1:
The flight controller serves multiple functions: it monitors flight parameters, identifies transition points, controls propulsor rotation, and responds to pilot override commands. The propulsors themselves are designed to function in both lift and thrust configurations. This multi-functionality reduces the need for separate dedicated systems for each function, thereby improving energy management efficiency while moderating manufacturing complexity.
