Fleming & Associates was founded in 1972 by August E. “Gus” Fleming, a pioneer in dynamic airflow measurement techniques. His entry into the field of airflow measurement came in the late 1950’s when an unexpected problem arose that could not be solved by conventional means. It was found that a gas turbine nozzle warped so badly during engine testing that the traditional mechanical testing tools used to measure and adjust the nozzle would no longer fit onto the part. Such testing and adjustment is critical to insure proper engine performance, and until his time all measurement was done mechanically. Gus developed a new, dynamic airflow process to determine the aerodynamic area of the nozzle, and other such gas turbine components.

The improvement in the accuracy and speed of testing obtained by using this dynamic process was so great that test procedures on gas turbine components were changed to take full advantage of this methodology. This led to the development of the AF16 Test Bed and AF36 Airflow Measurement System, as well as various adaptors to allow a variety of gas turbine components to be tested on the System. The AF36 has been continually refined since that time and is today the state of the art in dynamic measurement of gas turbine components.

Ronald J. Fleming, Gus’ son, took over the company after Gus’ retirement in 1992. Gus continues to be involved with Fleming & Associates Calibration, Inc. and is in the office on an almost daily basis. The company has continued to refine and sell its products.

Fleming & Associates Calibration, Inc. now has AF36 Airflow Measurement Systems in over 120 facilities worldwide and our customer base includes almost every entry into the gas turbine field.
