Aircraft Engine Yoke Mounting System with Interlocking Vibration Damping

Solution Overview

Problem

Existing aircraft engine mounting systems require multiple parts and redundant securement mechanisms, which can lead to safety issues during installation and operation, particularly due to potential failure points and pinch points between components.

Innovation Solution

An aircraft engine mounting system utilizing a yoke member with interlocking engine mounts, where the yoke member is secured between two engine mounts with specific spacing and alignment, eliminating the need for redundant hardware by ensuring retention through precise geometric relationships and material configurations, such as soft or hard mounts with vibration damping components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple parts and redundant securement mechanisms are used in existing aircraft engine mounting systems, then reliability is improved through backup security, but device complexity increases and potential failure points multiply

Engineering Contradiction:

ImprovesecurityVSAvoidnumber of parts

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple separate mounting components into a single integrated yoke member that features interlocking engagement with the engine pylon. This consolidation eliminates the need for multiple separate parts and redundant securement mechanisms while maintaining secure attachment through the interlocking geometry of the yoke member itself.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The invention extracts and eliminates redundant hardware and excessive securement mechanisms from traditional mounting systems. By removing these unnecessary components, the design reduces the total number of parts and potential failure points while the interlocking yoke member provides sufficient security through its geometric retention features.
