Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft systems lack an efficient mechanism for safely extending and retracting payloads stored in a payload bay while maintaining aerodynamic performance and ensuring consistent load reaction without rotation.
Innovation Solution
A system comprising tracks attached to the upper interior surface of a payload bay and extending along the bottom surface of the aircraft wing, with a rack moveably connected via a carrier assembly and a payload actuator system for selective extension and retraction, utilizing locking mechanisms to manage load and position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If payload is extended from payload bay along track, then payload deployment capability is improved, but aerodynamic drag increases
Solution Approach 1:
The payload extension system is divided into segmented components: payload bay, track segments along the wing, carrier assembly, and rack. This segmentation allows the payload to be extended only when needed while maintaining aerodynamic efficiency during retraction, resolving the contradiction between deployment capability and drag reduction.
Solution Approach 2:
The system transitions between static (retracted) and dynamic (extended) states based on operational requirements. The payload is retracted to minimize drag during flight and extended only when deployment is required, dynamically adapting to balance aerodynamic performance with operational capability.
2Adaptability or versatility
If rack is moved along track using carrier assembly, then payload extension flexibility is improved, but system complexity increases
Solution Approach 1:
The carrier assembly serves as an intermediary component between the track and the rack, enabling smooth movement and positioning of the payload along the track. This intermediary mechanism provides flexibility while managing system complexity by using a standardized interface that simplifies the interaction between moving parts.
3Reliability
If locking mechanisms are engaged at extended and retracted positions, then load reaction stability is improved, but device complexity increases
Solution Approach 1:
Locking mechanisms are pre-positioned at specific locations along the track corresponding to extended and retracted positions. These mechanisms are engaged automatically or manually at predetermined moments during payload movement, ensuring load reaction stability without requiring continuous active control, thus balancing reliability with manageable complexity.
