Modular Skid Assembly for Gas Turbine Engine Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing engine skid assemblies for gas turbine engines are not rated for heavy loads, leading to failures of front down bolts due to high loads, and there is a need for a modular and efficient solution for supporting and transporting large gas turbine engines.
Innovation Solution
A modular skid assembly with a first segment and a second segment, each equipped with engine support structures, tubular members, wheel assemblies, structural rings, and a hitch assembly, allowing for interchangeable configurations and disassembly for compact storage and transport, supporting both the gas producer and turbine power groups of the gas turbine engine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a single rigid skid assembly is used to support heavy gas turbine engines, then load-bearing capacity is improved, but device complexity and difficulty of storage/transport increase
Solution Approach 1:
The skid assembly is divided into multiple segments (first skid segment, second skid segment) that can be connected via replaceable members. Each segment has its own engine support structures, allowing the assembly to be configured in different arrangements (side-by-side, end-to-end) depending on the engine size and load requirements. This segmentation enables the system to handle heavy loads while maintaining ease of storage and transport through modular components.
Solution Approach 2:
The skid assembly incorporates replaceable members that allow dynamic reconfiguration of the segments. The replaceable members can be attached and detached to change the assembly configuration, enabling adaptation to different engine types and load conditions. This dynamic capability provides the strength needed for heavy loads while allowing the assembly to be disassembled for compact storage.
2Adaptability or versatility
If a modular skid assembly with replaceable members is used, then adaptability and ease of storage are improved, but connection reliability may worsen
Solution Approach 1:
The replaceable members are designed as distinct, interchangeable components that connect the skid segments. These members can be easily attached and detached, allowing the assembly to be reconfigured for different engine configurations (single engine, dual engines, different orientations). The segmented design with standardized replaceable members ensures reliable connections while maintaining high adaptability.
Solution Approach 2:
The replaceable members are designed with universal connection features that can accommodate different engine support requirements. The same replaceable member design can be used across different skid segment configurations, ensuring consistent connection reliability while providing versatility for various engine types and arrangements.
3Adaptability or versatility
If tubular members are fixed at multiple heights with holding brackets, then adaptability for different engine configurations is improved, but device complexity increases
Solution Approach 1:
The tubular members incorporate holding brackets at specific localized positions along their length, creating discrete height options for engine support. This local quality approach provides multiple mounting heights without requiring complex continuous adjustment mechanisms. The brackets are strategically positioned to offer adequate support for different engine configurations while maintaining relatively simple overall structure.
