Dr. Kurt L. NicholDr. Kurt L. Nichol

Kurt Nichol is President, CEO, and co-founder of APEX Turbine Testing Technologies in Spring Hill, TN. APEX was formed in August 2000 to better enable transition of HCF test and evaluation (T&E) technologies developed under the USAF HCF T&E Plan to the commercial sector. He has long been a key proponent of “holistic” test and evaluation where seamless integration of experimental and numerical methods becomes reality. His vision and leadership have influenced significant changes in standard T&E approaches used to assess HCF capability of components in high vibration environments at major aerospace organizations world-wide.

Prior to forming APEX, Dr. Nichol was employed by Sverdrup Technology, Inc., AEDC Group, as Chief Engineering Officer for Turbine Engine Structural Test & Evaluation. During his career at AEDC, Dr. Nichol was a key contributor in numerous evaluations of front-line fighter engines for the United States Air Force and Navy. He has spent hundreds of hours engaged in test coverage and detailed analysis of data which have led to the development of many time and labor saving approaches and tools. These approaches and tools form the basis for most of the products currently marketed by APEX. Prior to working at AEDC, Dr. Nichol worked as a structural engineer for Pratt & Whitney in West Palm Beach where he worked in turbine design, structural analysis and testing.

Kurt’s leadership of APEX is guided by his faith in Jesus Christ which compels him to treat his customers, vendors, employees, and competition with respect and dignity. He serves on the Board of Living Sent Ministries (www.livingsentministries.org) He and his family live in Franklin, Tennessee.
