About Us

Dr. Robert P. Dougherty, President 


Affiliate Associate Professor 
William E. Boeing Department of Aeronautics & Astronautics 
University of Washington

Dr. Dougherty has made leading contributions to the phased array aeroacoustic test technique, including beamforming algorithms, array design, and presentation of results. He has applied this technique to clarify airframe, turbomachinery, and jet noise sources. In addition, he has developed standard computer programs for predicting nacelle acoustic propagation by ray tracing (RDIFF) and the parabolic approximation (cduct); he also has developed concepts for nacelle acoustic design, including nacelle shape and lining placement.


Dr. Dougherty has written a number of technical papers and one book chapter. He has taught several courses including beamforming, nacelle acoustic propagation, and acoustics. He has conducted research programs for several agencies. In 2013 he invented "Functional Beamforming". He has four patents.

Dr. Dougherty is an ASSOCIATE FELLOW in the American Institute of Aeronautics and Astronautics.

Dennis L. Huff - Board of Directors


Dennis L. Huff is a retired Research Aerospace Engineer from the Acoustics Branch at the National Aeronautics and Space Administration (NASA) John H. Glenn Research Center at Lewis Field in Cleveland, Ohio. He retired in June 2021 after serving 36 years with NASA. Huff was Deputy Chief of the Aeropropulsion Division and Chief of the Acoustics Branch, and led teams from NASA, industry, and universities to develop engine-noisereduction technologies. Projects included chevron nozzles and swept/leaned stators that have been proven to reduce jet and fan noise and are being implemented by industry.
