R G Pettit, P W Scott: 2180. Application of Arall 3 to the C-17A Cargo Door. 1993.



Since 1985, McDonnell Douglas Aerospace has been developing ARALL laminate technology for new military and commercial aircraft. In 1988 effort was focused on identifying and evaluating various applications for the United States Air Force C-17 aircraft. Late that year, the cargo door skin application was authorized for production. This paper presents the reasons for selecting the cargo door for an ARALL laminate application over other candidates and reviews various design and manufacturing issues. A weight-strength analysis of the cargo door is also presented. Finally, a few remarks are dated at the future of the technology.
