Removable Helicopter Step Assembly with Modular Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing helicopter step systems do not provide adequate foot support during flight and are often difficult to install and remove without permanent modifications.
Innovation Solution
A modular step assembly system with adjustable and removable components, including a main tube, bushing housing, and adapter assembly, that can be easily mounted and dismounted on the helicopter, providing both entry/exit steps and in-flight foot support, with options for single or multiple levels and adjustable height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If steps are permanently attached to the fuselage or landing skids, then structural stability is improved, but ease of installation and removal deteriorates
Solution Approach 1:
The step assembly is divided into separate modular components including a step support, step elements, and mounting brackets that can be independently attached and detached. This segmentation allows the step to be securely installed when needed while enabling easy removal without permanent modifications to the helicopter structure.
Solution Approach 2:
The step assembly incorporates adjustable and removable components that transition between installed and removed states. The dynamic design allows the step to be securely fixed during operation providing stability, while enabling quick installation and removal when not needed, resolving the contradiction between permanent attachment and ease of operation.
2Reliability
If steps are permanently modified into the helicopter structure, then reliability is improved, but adaptability deteriorates
Solution Approach 1:
The step assembly is designed as a universal system that can be installed on various helicopter models and configurations without permanent modifications. The modular components and standardized mounting interfaces enable the same step assembly to adapt to different aircraft types while maintaining reliable performance through secure attachment during operation.
3Device complexity
If single-level steps are used, then device complexity is reduced, but functionality deteriorates
Solution Approach 1:
The step assembly incorporates multiple detachable step elements that can be configured in single-level or multi-level arrangements. This segmented design allows users to select the appropriate configuration for different operational needs without increasing overall system complexity, as the same modular components serve both single and multi-level functions.

AI summary
A removable step assembly for a helicopter includes a main tube, which supports a forward step and a rear step, as well as a bushing housing. The main tube is mounted to a helicopter by the bushing housing, an associated bushing, and by an adapter assembly that is secured to the cabin of the helicopter.
