Load-Factor Rotating Seats for Space Launcher Passenger Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing passenger transport systems propelled by space launchers require non-straight trajectories, which can be uncomfortable and require specific training due to high speeds, necessitating a solution to make these trajectories more bearable for passengers.
Innovation Solution
A transport system with rotating seats and cabins that adjust to the load factor experienced during flight, using a control unit to maintain a predefined rotation speed and orientation relative to the passenger's frame of reference, combined with radiation shielding and passenger interfaces for enhanced comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the transport system follows non-straight trajectories to reach desired altitude and speed, then the transport efficiency and speed are improved, but the passenger comfort deteriorates due to high G-forces and disorientation
Solution Approach 1:
The seat is made rotatable about the longitudinal axis of the vehicle, allowing its orientation to dynamically adjust during flight. The control unit rotates the seat in response to detected trajectory changes, maintaining optimal passenger orientation relative to the resultant force vector, thereby resolving the contradiction between high-speed maneuvering and passenger comfort
Solution Approach 2:
A detection unit continuously monitors the vehicle's trajectory and provides feedback to the control unit, which then adjusts the seat rotation accordingly. This closed-loop feedback system ensures the seat orientation continuously adapts to maintain passenger comfort during high-speed non-straight trajectories
2Device complexity
If the seat orientation is fixed relative to the vehicle, then the device complexity is reduced, but the passenger ability to withstand load factors deteriorates
Solution Approach 1:
The seat mounting system incorporates a rotation mechanism about the longitudinal axis, transforming a static fixed mounting into a dynamic adjustable mounting. This allows the seat to actively track and align with the load factor direction, significantly improving passenger tolerance to G-forces while adding only moderate rotational actuation components
Solution Approach 2:
The seat orientation parameter (rotation angle about longitudinal axis) is made variable rather than fixed. The control unit adjusts this parameter in real-time based on trajectory detection, optimizing the alignment between seat orientation and load factor direction to maximize passenger comfort during maneuvers
