The Modern Design of Experiments for Wind Tunnel Testing: A Practitioner's Guide to Formal Experiment Design for Low-Cost, High-Quality Testing in Experimental Aeronautics covers the background theory needed by those unfamiliar with Design of Experiments (DOE) methods, using detailed examples from decades of work at NASA Langley to demonstrate practical realities, applications and limitations. Pioneering NASA research scientist Richard DeLoach shares theoretical background, unrivalled practical experience and detailed examples of a new approach to aeronautical wind tunnel test design. The book is an essential reference to this novel approach from an experienced leader in the field.
In this ground-breaking new book, DeLoach examines the massive potential for cost savings and quality improvement through DOE methods of testing, driving great interest in the topic within the aerospace community. Understanding the needs of wind tunnel practitioners faced with insufficient resources for, and disappointingly unreliable results through, traditional One Factor At a Time (OFAT) testing, DeLoach has spent decades honing his take on the established Design of Experiments (DOE) approach and applying it to aeronautical testing in a wind tunnel setting. His papers on Modern Design of Experiments (MDOE) relating to experimental aeronautics have won him numerous AIAA 'Outstanding Paper' and 'Best Paper' accolades, as well as a NASA Exceptional Technology Achievement Medal in 2005.

Dr. DeLoach introduced the principles of formal experiment design to the wind tunnel testing community in the 1990's, coining the term "Modern Design of Experiments (MDOE) to describe an approach focused on acquiring new aerodynamic knowledge rather than simply collecting data in high volume. At conferences of the American Institute of Aeronautics and Astronautics (AIAA), MDOE papers authored by DeLoach have won eleven "Outstanding Paper or "Best Paper awards since 2000. He has lectured on MDOE at major government and commercial laboratories throughout the United States, as well as in Europe, Asia, and Africa, and has led "Concepts in the Modern Design of Experiments seminars for the AIAA for over a decade. In 2005, NASA presented DeLoach with its Exceptional Technology Achievement Medal "for pioneering the development and application of the Modern Design of Experiments in aeronautical research that revolutionized the wind tunnel testing process.
