What type of turbine blading is used for installation in circumferential grooves?

• A. Flat blading
• B. Curved blading
• C. Tee-root blading
• D. Clip blading

Answer: (C)

The use of tee-root blading in circumferential grooves is primarily due to its design, which allows for a secure and effective attachment within the turbine casing. This type of blading features a T-shaped root that fits snugly into the machined grooves, providing stability and minimizing the potential for movement during operation. The design enables a more efficient transfer of forces and helps in maintaining the alignment of the blades under operational stresses. Additionally, tee-root blading is beneficial for maintenance and replacement since the T-shape can be more easily installed and removed from the grooves, simplifying the overall service process of the turbine. This structural integrity and ease of maintenance make tee-root blading a preferred choice in many turbine applications, especially in those that utilize circumferential grooves for blade retention. Other types of blading, such as flat, curved, or clip blading, do not provide the same level of compatibility with circumferential grooves and may lead to complications in installation, retention, and performance within the turbine system.
