Structural Design and Testing: Outline of the Structural Design Philosophy, Detail Design and Testing Programme of the Argosy Series 100 and Argosy Series 200 Aircraft

AS outlined in the description of the evolution of the Argosy design, a decision was taken to develop the Shackleton wing for the Argosy in order to reduce design development and manufacturing time. This was of fundamental importance on the structural side, as it postulated the use of a mass boom type wing spar for the first 10 Series 100 Argosies, and this same type of wing structure was used also for the fifty‐six military Argosies. The following description of the structural design of the aircraft starts with the Series 100 and is followed by a description of the changes introduced by the adoption of a box spar wing on the Series 200.
