With a heavy heart we announce that Dr. Jan Roskam passed away on September 9, 2022 at the age of 92.  In 1991 Dr. Roskam co-founded, with Dr. Willem Anemaat, Design, Analysis and Research Corporation (DARcorporation) and functioned as president until 2004.  From 2004 until 2019 he served as Project Advisor.  After his retirement he stayed on as a consultant to DARcorporation.

During his tenure at DARcorporation Dr. Roskam supervised the technical aspects of all consulting work.  He reviewed all consulting work and was involved with all engineering meetings for consulting projects.

Dr. Roskam authored a two-volume text called: Airplane Flight Dynamics and Automatic Flight Controls and an eight-volume text called: Airplane Design and he co-authored (with Dr. C. Edward Lan) Airplane Aerodynamics and Performance.  These texts are used by universities and aerospace companies, worldwide, and are published by DARcorporation.  In his later years, he wrote Roskam’s War Stories and Lessons Learned in Aircraft Design, also published by DARcorporation.

Dr. Roskam was actively involved on over 400 aircraft design and analysis projects at DARcorporation over the last 31 years.

Our condolences go out to his wife Janice Thomas Barron.
