This document is intended for use as a design handbook for the ringsail parachute. It begins with an historical review of the aerodynamic and structural development of the parachute, including the development of the modified ringsail design used in the Apollo ELS main parachute cluster. Salient characteristics of all ringsail parachutes fabricated and tested over the past 16 years are summarized. An explosion of the present status of ringsail design and operational theory, with special emphasis on a general theory of the inflation characteristics of clustered canopies, is given. Accumulated performance and weight data are presented in tabular and graphical form. A detailed step-by-step procedure for the design of the ringsail parachute is given and illustrated by numerical example. (Author)
