Book Description
An analysis yielding six-degree-of-freedom equations of motion is presented for predicting the dynamic behavior of a general parachute-payload system. The parachute canopy and associated air-mass are approximated as a rigid body, and separate equations of motion are derived for the canopy and payload subject to the constraint of the risers and suspension lines. The analysis determines the forces and the response of various riser and suspension-line geometries subjected to large displacements, under the assumption that these lines are linearly elastic. The euqations are readily adaptable to computer solutions and should be of interest in analyzing the dynamic performance of lifting-parachute payload systems.

Book Description
This document serves as the third revision of the USAF Parachute Handbook which was first published in 1951. The data and information represent the current state of the art relative to recovery system design and development. The initial chapters describe representative recovery applications, components, subsystems, material, manufacture and testing. The final chapters provide empirical data and analytical methods useful for predicting performance and presenting a definitive design of selected components into a reliable recovery system.
