Aircraft Front Engine Mount Transverse Beam Spatial Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing aircraft propulsion assemblies require a large vertical transverse spatial area due to the configuration of the front engine mount, which is not efficiently optimized for reduced spatial requirements.
Innovation Solution
The front engine mount incorporates a transverse beam partially positioned opposite the front transverse reinforcement of the primary structure, with connection elements and brackets arranged to reduce vertical transverse spatial requirements, including an upper extension and lateral extensions connected to the primary structure and engine via specific connection axles and rods.

Engineering Contradiction Analysis
1Ease of operation
If the transverse beam is positioned below the primary structure perpendicular to the front transverse reinforcement, then the front engine mount can be connected to the primary structure and engine, but the vertical transverse spatial area occupied is large
Solution Approach 1:
The transverse beam is repositioned from a configuration entirely below the primary structure to one that is partially opposite the front transverse reinforcement, utilizing the transverse dimension more efficiently. This dimensional redistribution reduces the vertical transverse footprint while maintaining all necessary connection capabilities through strategically positioned connection elements.
Solution Approach 2:
The transverse beam is divided into multiple segments: a first portion opposite the front transverse reinforcement, a second portion extending rearward, and connection elements distributed along its length. This segmentation allows different portions to serve different functions (spatial optimization, structural connection, force absorption) simultaneously, reducing overall spatial requirements while maintaining connectability.
2Area of stationary object
If the transverse beam is repositioned to reduce vertical transverse spatial area, then spatial requirements are optimized, but force absorption capability must be maintained
Solution Approach 1:
Different portions of the transverse beam are assigned different functional qualities: the first portion opposite the front transverse reinforcement optimizes spatial arrangement, while connection elements (vertical connection elements, beam connection axles, engine connection axles) are strategically positioned to handle force absorption. This local differentiation allows spatial optimization without compromising force absorption capability.
Solution Approach 2:
The invention merges multiple functions into the repositioned transverse beam structure: spatial optimization through positioning opposite the front transverse reinforcement, structural connection through vertical connection elements, and force absorption through the integrated beam-connection element-engine assembly. This functional merging achieves compact spatial arrangement while maintaining comprehensive force absorption capability.
