Title: Rafael A De Cardenas: Innovator in Thermal Barrier Coating and Turbine Cooling Systems

Introduction

Rafael A De Cardenas is a notable inventor based in Orlando, FL (US). He has made significant contributions to the field of engineering, particularly in the development of methods and systems that enhance the performance and efficiency of turbine engines. With a total of 4 patents to his name, his work reflects a commitment to innovation and excellence.

Latest Patents

One of Rafael's latest patents is a method of cleaning a component having a thermal barrier coating. This method involves providing the component after its operation in a high-temperature environment, where the component includes a thermal barrier coating (TBC). The cleaning process utilizes a sponge jet blasting technique, and it includes measuring the cleaned thickness of the TBC to ensure it exceeds a predetermined minimum value, allowing the component to return to high-temperature operations.

Another significant patent is for a turbine airfoil cooling system with rotor impingement cooling. This system features a hollow, disc post body positioned between adjacent roots of turbine airfoils, designed to cool the inner aspects of the turbine engine. The hollow, disc post body is configured to pass cooling fluids through impingement orifices, which then impinge on the inner surfaces of the turbine airfoils' platforms. This innovative approach directs cooling fluids to the internal cooling systems of the turbine airfoils, rather than discharging them as film cooling fluids.
