Crash Lethality Model
Abstract
The purpose of this report is to evaluate the possible modes in which an Unmanned Air System (UAS) could inflict life threatening injuries to 3rd party individuals and develop a model that would calculate the total Lethal Crash Area (LCA) given some standard UAS calculations. A literature search was done to evaluate previous models at determining LCA from aircraft accidents. Two cases were proposed, an inert case in which the individual was impacted by the air vehicle and energetic case where components of the vehicle, namely aviation fuel, reacted to result in a hazardous area around the air vehicle. This report investigated several methods for developing models that could capture both these cases, as well as submodes for each case. An interactive decision making tool, the 3rd Party Risk Assessment Tool was constructed based on the conclusions found in this report. Using the tool, a decision maker may determine the total area related to aircraft parameters can be used to assess 3rd party risk. Ten UAS cases were evaluated and suggest that the factor most correlated to the size of the LCA is the weight of the air vehicle.
