Jan Roskam

Jan Roskam (February 22, 1930 – September 9, 2022) was a Dutch-born American aircraft designer. He was the Deane E. Ackers Distinguished Professor of Aerospace Engineering at the University of Kansas. He was also the author of eleven books on airplane design and flight dynamics and over 160 papers on the topics of aircraft aerodynamics, performance, design and flight controls.^[1] He founded the company DARcorporation with Willem Anemaat.

Born in The Hague on February 22, 1930,^[2] Roskam received his engineer's degree in aeronautical engineering in 1954 from the Delft University of Technology followed by a Ph.D. degree from the University of Washington in aeronautics and astronautics in 1965.

Roskam has been involved in the design and development of 36 aircraft programs, including 12 which made it to flight, while working for three major aircraft companies.^[3] He was actively involved in design and development of the Boeing SST, Cessna Citation I, and Learjet 35. He also acted as a consultant on the Boeing 747.^[4] He was particularly proud of his work on the Piaggio P-180 Avanti.^{[citation needed]}

In 1967 he became a Professor of Aerospace Engineering at the University of Kansas. He served as chairman of the department from 1972 to 1976 and was recognized as the Ackers Distinguished Professor of Aerospace Engineering from 1974 until his retirement in 2003. During his time at the university he continued to serve as a member of various advisory committees to NASA and was a member of the X-29 future applications committee. He was involved in founding the Aerospace Short Course program at the University of Kansas in 1977, which has grown into a center for aerospace professional development and training, and he still teaches for the program.^{[citation needed]}

In 1991, Roskam co-founded the Design, Analysis and Research Corporation (DARcorporation) with Willem Anemaat in Lawrence, Kansas. He served as the company's president until 2004.^[3][5] The main focus of the company is design consultation, software and textbooks in the aviation field. The company developed its own aircraft design software, Advanced Aircraft Analysis (AAA), as well as a second design program for a NASA Small Business Innovative Research contract.^[5]

In 2002 he published Roskam's Airplane War Stories a collection of stories about airplane design and analysis and engineering mistakes that were made. Many of the stories are based on his own experiences and have previously been used to demonstrate to young engineers that "when we make mistakes, we kill people". Roskam has written eleven books on airplane design and flight dynamics.

Shortly before his retirement in 2003, Roskam received the Chancellor's Club Award for his career in teaching, recognizing his exceptional teaching history.^[4] His former students include Alan Mulally, former president and CEO of Boeing Commercial Airplanes.^[6] Mulally calls Roskam one of his heroes and notes that he learned important skills such as team-building during Roskam's courses.^[7] Roskam is also credited with helping Mulally get his first job at Boeing.^[8]

The American Institute of Aeronautics and Astronautics honored him with the AIAA Aircraft Design Award in 2007. The award is given each year for advancements in the area of aircraft design, in Roskam's case the award was to recognize his lifetime contribution to the fields of airplane and configuration design and education.^[9][10]

Roskam died on September 9, 2022, at the age of 92.^[11]
