TURBOMACHINE ROTOR HAVING IMPROVED VIBRATORY BEHAVIOUR - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240035385 titled 'TURBOMACHINE ROTOR HAVING IMPROVED VIBRATORY BEHAVIOUR

Simplified Explanation

The patent application describes an assembly with a central axis and a body surrounding it. The body has a surface from which multiple blades extend, each with a root and a tip. The blades have the same height relative to the central axis. The innovation lies in the fact that each blade is connected to the body through its root using a connection with a non-zero height. This means that the connection height between two successive blades is different.

  • The assembly has a body with blades extending from its outer surface.
  • Each blade is connected to the body through its root using a connection with a non-zero height.
  • The connection height between two successive blades is different.
  • The blades have the same height measured radially relative to the central axis.

Potential Applications:

  • Wind turbines: The assembly could be used in wind turbines to improve efficiency and reduce noise by optimizing the airflow around the blades.
  • Gas turbines: The design could be applied to gas turbines to enhance the performance and stability of the turbine blades.
  • Fans and propellers: The assembly could be used in fans and propellers to improve their aerodynamic properties and increase their efficiency.

Problems Solved:

  • Improved aerodynamics: The non-zero connection height between the blades and the body helps optimize the airflow around the blades, reducing turbulence and improving overall performance.
  • Enhanced stability: The different connection heights between successive blades contribute to better stability and control of the assembly, especially in high-speed applications.
  • Noise reduction: The innovative design can help reduce noise generated by the assembly, making it suitable for applications where noise is a concern.

Benefits:

  • Increased efficiency: The optimized airflow and improved stability result in higher efficiency, leading to reduced energy consumption and improved performance.
  • Enhanced durability: The design improves the structural integrity of the assembly, increasing its lifespan and reducing maintenance requirements.
  • Noise reduction: The assembly's design helps minimize noise generation, making it suitable for noise-sensitive environments.
  • Versatility: The assembly can be applied to various types of turbines, fans, and propellers, providing a versatile solution for different industries.


Original Abstract Submitted

assembly comprising a body extending around a central axis, the body having an outer surface from which a plurality of blades extend, each of said blades having a blade root and a blade tip, defining an inner radial end and an outer radial end of the blade relative to the central axis, said blades having the same blade height measured radially relative to the central axis, characterized in that each of the blades is connected to the body by its blade root via a connection having a nonzero connection height, so that for the plurality of said blades, the connection height of two successive blades is different.
