Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft maintenance equipment lacks an efficient and versatile solution for supporting and removing helicopter tail booms during maintenance, which requires a stable and adjustable setup to handle the weight and positioning of the tail rotor boom assembly safely and efficiently.
Innovation Solution
A tail boom support stand assembly featuring a telescopic support system with adjustable vertical and horizontal components, webbing arrangements, and lockable casters, allowing for secure cradling and easy movement of the tail boom, including a forward and aft telescopic assembly with diagonal and horizontal stabilizer supports, and a frame structure that interconnects these components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid support structure is used for the tail boom, then stability and strength are improved, but the ability to accommodate different tail boom sizes and shapes is reduced
Solution Approach 1:
The support structure is divided into multiple segments including telescopic support assemblies with adjustable lengths, webbing arrangements with multiple straps, and modular cradle components. This segmentation allows each part to be independently adjusted to accommodate different tail boom configurations while maintaining overall structural integrity and strength.
Solution Approach 2:
The support structure incorporates dynamic elements such as telescopic support assemblies that can extend and retract, webbing arrangements that can be tightened or loosened, and adjustable cradle positions. These dynamic features enable the rigid support structure to adapt to various tail boom sizes and shapes while maintaining the necessary strength and stability.
2Stability of the object's composition
If a fixed support structure is used, then structural stability is improved, but ease of adjustment for different maintenance positions is reduced
Solution Approach 1:
The support structure transitions from a completely fixed design to a dynamically adjustable one, featuring telescopic support assemblies with lockable mechanisms, webbing arrangements with adjustable tensioning, and movable cradle positions. These dynamic elements allow maintainers to easily adjust the support configuration to different positions while maintaining structural stability when locked in place.
Solution Approach 2:
The support structure allows for parameter changes including telescopic support lengths, webbing tension levels, cradle positions, and stabilizer angles. These adjustable parameters enable the structure to be configured for different maintenance positions and tail boom weights, providing both ease of operation and structural stability through proper parameter selection and locking.
3Ease of operation
If a single-person operation system is used, then ease of operation is improved, but the ability to handle heavy tail rotor assemblies is reduced
Solution Approach 1:
The support structure incorporates stabilizer supports with adjustable legs that extend outward to create a wider base of support, effectively counterbalancing the weight of heavy tail rotor assemblies. This anti-weight principle allows a single maintainer to safely handle and position heavy components by distributing the load across a broader footprint and utilizing gravitational counterbalance.
Solution Approach 2:
The system uses dynamic adjustment mechanisms including telescopic support assemblies that can be extended to provide additional leverage, webbing arrangements that can be progressively tightened, and stabilizer supports that can be adjusted during the lifting and positioning process. These dynamic features enable a single person to manage heavy loads through mechanical advantage and progressive stabilization.
