Estimation of Firewall Loads Due to Soft Soil Impact
Overview Emergency landings on soft soil represent one of the most severe impact conditions encountered during aircraft accidents. The loads generated during these events are of special interest to crashworthiness engineers since they are needed to design the structure forward of the firewall in order to mitigate the airframe accelerations. The cabin structure must also be sized for these loads to ensure that a survivable volume is maintained throughout the impact response. All nose-down impacts are of interest, but those into soft soil represent the critical condition because of the potentially large longitudinal forces associated with the momentum transfer of the displaced soil. The nacelle and engine mount designs in aircraft with a conventional tractor propulsion configuration play an important role in aircraft response.
