Dr. Jan Roskam
(1930 – 2022)

Past President

Dr. Roskam retired as the Dean E. Ackers Distinguished Professor in Aerospace Engineering at The University of Kansas in Lawrence, Kansas in 2003. He authored a two-volume text called Airplane Flight Dynamics and Automatic Flight Controls and an eigh-volume text called Airplane Design. He co-authored (with Dr. C. Edward Lan) a text called Airplane Aerodynamics and Performance. These texts are used by more than fifty universities and by aerospace companies in the USA and abroad. In addition he authored or co-authored over 150 papers, articles and technical reports. Dr. Roskam was a Fellow in the AIAA (American Institute of Aeronautics and Astronautics), a Fellow in the SAE (Society of Automotive Engineers) and a Fellow in the Royal Aeronautical Society (England). He authored of more than 155 publications including 16 textbooks on aeronautical engineering. He worked on the design and development of more than 36 different airplane types. Dr. Roskam also piloted more than 38 different types of airplanes.

Before joining K.U. in 1967, Dr. Roskam had twelve years of experience working for Aviolanda Aircraft Co. (in The Netherlands), for Cessna Aircraft Co. (in Wichita, Kansas) and for The Boeing Company (in Wichita, Kansas and in Seattle, Washington). He received his MSAE (1954) from the Delft University of Technology (The Netherlands) and his Ph.D. in Aeronautics and Astronautics (1965) from The University of Washington (Seattle).

Before co-founding DARcorporation, Dr. Roskam was a consultant to companies in the USA and in Europe and also served as a consultant to NASA, USAF and DARPA. Dr. Roskam had been actively involved in the design and development of the following aircraft: Aviolanda AT 21, Cessna T-37, Boeing TFX design, Boeing SST design, Learjet Models 25, 35/36 and 55, Cessna Citation I, SIAI Marchetti S-211 and Piaggio 180-Avanti. Jan Roskam managed the low speed and transonic speed wind tunnel programs for the SIAI Marchetti S-211 and Piaggio 180-Avanti. In 1991 Jan Roskam co-founded DARcorporation and functioned as president until 2004. He supervised the technical aspects of all consulting work. Dr. Roskam reviewed all consulting work and was involved with all engineering meetings for consulting projects.
