Title: Innovations by Clayton M. Grondahl

Introduction

Clayton M. Grondahl is a notable inventor based in Clifton Park, NY (US). He has made significant contributions to the field of gas turbine technology, holding a total of 5 patents. His work focuses on improving cooling systems and airfoil designs, which are critical for enhancing the efficiency and performance of gas turbines.

Latest Patents

One of his latest patents is titled "Cooling system utilizing flow resistance devices to distribute liquid." This innovative cooling system employs flow-resistant devices to effectively distribute liquid coolant to airfoil coolant channels within a turbine's bucket. Each coolant channel is equipped with a separate flow resistance device that regulates the flow of liquid coolant, creating a fluid head in a standpipe upstream. This design allows for better control of fluid flow through various resistance devices, which can take the form of tortuous passages, orifices, or vortex flow chambers.

Another significant patent is the "Method for forming a liquid cooled airfoil for a gas turbine." This method involves creating a series of holes in an oversized airfoil blank, into which pre-formed composite liquid coolant tubes are bonded. These tubes consist of an inner member made from anti-corrosive material and an outer member with high thermal conductivity. After bonding, the airfoil blank is machined to the desired shape, ensuring that part of the outer member of each tube is in contact with the airfoil's surface. Finally, an external skin is bonded to the airfoil and the composite tubes, enhancing the overall design.
