Section 11.17 describes impact attenuation if the vehicle werepermitted to impact the ground as part of its arresting technique.If the vehicle is designed with crumple zones, the impulse-momentumequation can be described as:
FZ⋅LStroke=WRecovery2⋅g⋅Vz,Impact2
Where,
From this equation, the level of force of the impact,FZ , along the z-axiscan be derived based upon the length of the vehicle’s crumple zone,LStroke along thez-axis and the vehicle’s velocity along the z-axis, Vz, Impact .
