Airworthiness Classification of Unmanned Aircraft Systems Based on Risk Assessment of Operational Scenario
Abstract:   (397 Views)

This paper introduces a novel strategy for the specification of certification of airworthiness (CoA) categories for unmanned aircraft systems (UAS). Logical approach in this classification, based on determination of allowable risk for an UAS supposing of operational scenario that using from this parameter as alone criteria for segregation of manned and unmanned airworthiness. In this research, for issuance of CoA in scope of UAS, is proposed regular matrix according to risk table of mil-std-882 that based on, level of airworthiness control on the design & construction of UAS’s with various missions, is specified. Referral point of the present work, is validation on proposed matrix with statistical work upon greater than 500 kinds of military and civil UAS that has been accomplish in two stage and with computation of two criteria as maximum kinetic energy and hazard area from physical, performance and aerodynamic specification each UAS with aim of determination of risk. For this intent in first step, attention to introduced various level of injury in references, is specified limits for kinetic energy that respect to their current UAS in archive is categorized and is conformed with introduced categories in proposed matrix. In next step, with creation of statistical algorithm is defined limits for hazard area parameter that in beside limits of kinetic energy, meanwhile increase the precision in proposed categorization for UAS in certification matrix, this matrix is validated again. Such after determination of certification category on the proposed matrix, this certification issue on what limitation of requirements and design & construction regulations, is subject that will implement in next issuance. Important point correspond to this technique, is degeneration and no confliction of introduced methodology for determination of CoA category of an UAV with regulations framework of part 21.

Keywords: UAS, Airworthiness, Hazard area, Operational scenario, Risk assessment
