A Case Study of the Application of Model Based Systems Engineering to a UAS Systems Engineering Process The goal of this student project is to use a combination of well-known Systems Engineering best practices and modelling by means of SysML notation for the engineering of the K2B UAS (Unmanned Aircraft System) used for generic civil missions. A former member of the K2 family is shown in Figure 1 . The Systems Engineering community describes the Systems Engineering process as an iterative approach to technical management, acquisition and supply, system design, product realization, and technical evaluation at each level of the system, beginning at the top and propagating them through a series of steps, which eventually lead to a preferred system solution. The aim of functional analysis is to create a functional architecture that is the input for defining the physical architecture through the allocation of functions to the system components. Large systems are often made up of subsystems that are logically and physically partitioned into parts or components. Aggregation allows us to consider the thing as a unit, ignoring its parts, a simplification in thought. Alternatively, hierarchy lets us consider a component as an assembly of parts to think how it is built. The Systems Engineering process used here has three main steps: (1) Defining the UAV operational concepts; (2) Modelling the UAV functional architecture; (3) Modelling the UAV physical architecture. The operational concepts are described by 14 operational scenarios using the Use Cases modelling technique and complemented with a state diagram describing the main operational states of the UAV. Some of the operational scenarios identified are Starting the UAV, turn manoeuvre, automatic flight path execution, and landing manoeuvre. The UAV functional architecture, displayed in Diagram 1 , represents a hierarchical view of the UAV capabilities without considering the implementation solution. Here the SysML block diagram is used to describe the UAV functional hierarchy. A five-level block hierarchy identifying more than 130 UAV functions was produced. These hierarchical diagrams are complemented with a N 2 chart, Table 1 , to represent the main functional interfaces. The physical architecture shows the main UAV subsystems, their interfaces and their internal parts represented as blocks in SysML. Here, for illustrative purposes, the UAV fuel system is shown in Diagram 2 . Student: Mario Garcia Garcia | Supervisor: Jose Luis Fernandez Sanchez UAV Relative Position to the Aerodrome.
