Solution Overview
Problem
Existing Kinetic Hydro Power (KHP) turbine systems face challenges in securely mounting and efficiently replacing rotor blades, which affects the turbine's performance and efficiency due to complex and cumbersome mounting arrangements.
Innovation Solution
A unique rotor hub design with three interconnected mounting plates and a cylindrical structure that allows for easy assembly and secure attachment of rotor blades, enabling efficient blade replacement and a streamlined connection, using a mounting plate system with complementary root plate designs for secure and efficient mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing mounting arrangements are used for KHP turbine blades, then the turbine can operate, but the mounting structure becomes complex and cumbersome, making blade replacement difficult
Solution Approach 1:
The rotor hub is divided into three separate mounting plates positioned at 120-degree intervals, each capable of independently securing a rotor blade. This segmentation allows individual blade replacement without affecting other blades, simplifying maintenance operations while maintaining structural integrity through the distributed plate configuration
Solution Approach 2:
The mounting system incorporates removable and replaceable mounting plates that can be dynamically installed or removed from the rotor hub. This dynamic capability enables easy blade replacement by simply detaching the affected mounting plate, transforming a previously static and complex mounting arrangement into a flexible, maintainable system
2Reliability
If complex mounting arrangements are used, then blade security may be improved, but the overall structure becomes cumbersome and less efficient
Solution Approach 1:
Each mounting plate is designed with specific local features including angled mounting surfaces, positioning protrusions, and securing mechanisms tailored to its location on the rotor hub. This localized optimization ensures each plate provides secure blade attachment while maintaining a simple overall structure, avoiding the need for complex universal mounting arrangements
Solution Approach 2:
The mounting plates are nested within the rotor hub structure, with each plate positioned in a recess or cavity of the hub. This nesting arrangement secures the blades firmly within the hub while keeping the external hub structure simple and streamlined, eliminating the need for complex external mounting frameworks
3Ease of repair
If traditional rotor hub designs are used, then assembly may be straightforward, but blade replacement becomes difficult and time-consuming
Solution Approach 1:
The mounting plates are pre-positioned and secured to the rotor hub during initial assembly, with built-in features such as positioning protrusions and angled surfaces that guide rapid blade installation. This preliminary preparation eliminates the need for complex alignment procedures during blade replacement, significantly reducing maintenance time while ensuring proper blade seating
Solution Approach 2:
The design allows for the easy removal and replacement of individual mounting plates, which can be efficiently discarded from service and replaced with new or refurbished plates. This approach enables rapid blade replacement by simply removing the affected mounting plate and installing a replacement, minimizing downtime without requiring complex disassembly of the entire rotor assembly

AI summary
A rotor hub mounting arrangement for removably mounting a plurality of turbine rotor blades to the rotor hub in a compact and secure manner. The rotor hub includes an internal mounting assembly, preferably comprised of a series of interconnected mounting plates, positioned adjacent a series of foil shaped openings in the rotor hub into which the root end of turbine blades can be inserted and removably mounted to the internal mounting assembly.
