Aircraft Engine Support Frame for Inclined Mount Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The attachment of aircraft engines to inclined surfaces on main planes is complicated and time-consuming due to the difficulty in aligning the engine with the inclined surface using conventional lifting devices.
Innovation Solution
A device comprising a linear movement device and a swinging device that supports the engine along a horizontal direction and allows it to be inclined and positioned accurately on an inclined surface by adjusting its angle using swinging mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional crane is used to raise the engine vertically, then the engine can be lifted to the attachment position, but the engine cannot be aligned with the inclined surface of the main plane
Solution Approach 1:
The support frame is designed to be dynamically adjustable, allowing it to swing between a horizontal state (for engine loading) and an inclined state (for attachment). This dynamic transformation enables the same structure to perform multiple functions: horizontal movement for positioning and inclined positioning for alignment with the main plane surface.
Solution Approach 2:
The invention adds a swinging dimension to the conventional vertical lifting mechanism. By introducing the first swinging device that enables rotation about a first center axis, the system transitions from purely vertical movement to a combination of vertical and angular movements, allowing the support frame to match the inclined angle of the main plane.
2Reliability
If the engine is attached directly to the inclined surface without proper alignment, then the attachment process is simplified, but the attachment precision and reliability are compromised
Solution Approach 1:
The support frame is preliminarily positioned in the horizontal state to facilitate easy engine loading and initial positioning. This preliminary horizontal positioning action allows the engine to be securely placed on the support frame before the swinging and vertical movement operations begin, ensuring proper alignment from the start.
Solution Approach 2:
The support frame acts as an intermediary device between the conventional vertical lifting mechanism and the inclined attachment surface. It receives the engine in a horizontal state, then transforms its orientation to match the inclined surface, serving as a bridge that reconciles the mismatch between vertical lifting and inclined attachment.
3Measurement precision
If multiple devices are used to achieve both vertical lifting and angular adjustment, then positioning precision is improved, but the device complexity increases
Solution Approach 1:
The invention merges the functions of vertical lifting and angular adjustment into a single integrated support frame system. The support frame combines the first swinging device (for angular adjustment) and the linear movement device (for vertical positioning) into one unified structure, eliminating the need for separate lifting and positioning devices.
Solution Approach 2:
The support frame is designed as a multi-functional device that can perform horizontal movement, vertical movement, and angular swinging operations. This universal structure replaces multiple specialized devices, achieving positioning precision through integrated functionality rather than through a complex assembly of separate components.

AI summary
A device and a method for attaching an aircraft engine include a linear movement device that supports a support frame for supporting the aircraft engine along a horizontal direction to freely move along a movement direction orthogonal to a rotation center axis of the aircraft engine, and a first swinging device that supports the support frame to freely swing about a first center axis parallel with the rotation center axis.
