Fuselage Collision Load Distribution via Wing-Support Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional urban air vehicles lack sufficient safety measures to prevent impact loads from being directly transferred to the occupant space during collisions, compromising passenger safety.
Innovation Solution
A collision load distribution structure comprising a support unit, wing unit, and seat unit that transfers and distributes impact loads through connections between the front, rear, and wing units, reinforcing transverse and vertical rigidity of the fuselage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fuselage structure is used, then manufacturing is simpler, but collision load is directly transferred to occupant space compromising safety
Solution Approach 1:
The fuselage is divided into front unit, rear unit, and wing unit as separate structural segments. The support unit connects these segments through specific connection points, allowing collision loads to be distributed across multiple segments rather than transferred directly to the occupant space. This segmentation enables independent structural optimization for each unit while maintaining overall safety.
Solution Approach 2:
The seat unit is designed with dual functionality: it provides seating for occupants and simultaneously serves as a structural reinforcement element. By extending the seat backrest to connect with the support unit and incorporating connection frames that link to both the floor frame and support structure, the seat unit reinforces transverse rigidity and vertical rigidity of the fuselage in multiple dimensions.
2Strength
If rigid structure is used to prevent deformation, then strength is improved, but impact load is directly transferred to occupants
Solution Approach 1:
The support unit acts as an intermediary structural element between the front and rear units. It includes connection frames that connect to both units and provide designated connection points for load transfer. This intermediary structure distributes collision loads through multiple connection paths rather than allowing direct transfer to the occupant space, reducing harmful impact forces while maintaining overall structural strength.
3Stability of the object's composition
If seat unit is integrated with structural frames, then rigidity is enhanced, but manufacturing complexity increases
Solution Approach 1:
The seat unit is designed to perform multiple functions: it provides seating for occupants while simultaneously serving as a structural reinforcement element. The connection frames are integrated into the seat unit design, allowing it to connect with both the floor frame and support unit. This multi-functionality enhances transverse and vertical rigidity without requiring separate reinforcement structures, thereby reducing overall manufacturing complexity.

AI summary
Proposed is a collision load distribution structure of a fuselage, wherein the structure includes a support unit positioned between a front unit and a rear unit of the fuselage and configured to allow a collision load of the fuselage to be transferred by being connected to the front unit and the rear unit, a wing unit positioned at the inside of the support unit and connected to the support unit to transfer the collision load of the fuselage, and a seat unit coupled to a connection frame mounted in a second-row passenger space of a floor frame constituting the front unit and fastened to a first rear frame extending in a height direction from the floor frame toward the support unit.
