Title: Leonard J Meyer: Innovator in Turbomachinery Technology

Introduction

Leonard J Meyer is a notable inventor based in Mesa, AZ (US), recognized for his contributions to turbomachinery technology. With a total of 2 patents, he has developed innovative solutions that enhance the performance and efficiency of gas turbine engines.

Latest Patents

Meyer’s latest patents include an "Adjustable blade root spring for turbine blade fixation in turbomachinery." This device is designed to be placed in a rotor disk cavity adjacent to the tip of a blade root fir tree. It applies a radial outward force on the turbine blade to secure its position within the rotor disk. The device features an accordion-shaped spring that is compressed by a bolt and a coil spring. When compressed, the accordion spring increases in height, making contact with both the rotor disk and the turbine blade. The force exerted by the accordion spring can be adjusted via the bolt, while the coil spring provides an increased compliance range. This innovative device can be inserted into the designated space without scraping against the blade root or rotor disk, allowing for expansion once in position.

Another significant patent is the "Ring segment with forked cooling passages." This invention pertains to a gas turbine engine and includes a panel with an integrated cooling system. The cooling fluid is supplied to the outer side of the panel, while the inner side defines a portion of the hot gas flow path through the engine. The cooling system, located within the panel, receives cooling fluid from the outer side for effective cooling. It features multiple cooling fluid passages, each with a generally axially extending portion that includes at least one fork. These forks divide each passage into downstream portions, ensuring efficient cooling fluid distribution.
