Title: Innovations of Cheng-Chien Chou
Introduction
Cheng-Chien Chou is an accomplished inventor based in Carmel, IN (US). He holds three patents that showcase his expertise in engineering and design. His work primarily focuses on advancements in gas turbine technology and fan blade efficiency.
Latest Patents
One of his latest patents is for an "Iris control for gas turbine engine air brake." This invention involves a gas turbine engine of the two-shaft free turbine type, which includes a first gasifier turbine that drives a compressor. This compressor supplies air to a combustor for combustion with fuel, producing motive fluid for driving the compressor turbine and a second free-wheeling power turbine. The air brake features a compressor impeller directly coupled to the power turbine, equipped with an inlet and exhaust, along with a close-coupled iris throttle assembly. This assembly regulates the inlet flow of air into the compressor, maximizing power turn-down ratios without causing aerodynamic instability.
Another significant patent is the "Sheet metal fan," which features a blade design that improves performance and efficiency. The fan blade has a varying camber angle and chord angle along its radial positions. This design ensures that the angle of attack along at least 70% of the blade's length remains between 2 degrees and 10 degrees. This innovative fan blade construction is particularly useful in automotive radiator cooling systems.
