Title

Calculation of Stopping Torques for Limbs Subjected to Aerodynamic Loads

Abstract

Ejection from high speed aircraft during emergencies expose the limb segments of crewmembers to inertial and aerodynamic loads that can result in flail injuries. In this study, maximum joint torques necessary to stop the limb segment motion were calculated using a gross motion simulation model. A linear relationship between the restoring torque and joint flexure was assumed in the calculations. Results show that large joint torques are necessary to stop the limbs within relatively small specified angles and vice versa. The method described and the calculations made are useful in the design of limb restraint evaluation devices and dummies.
