Aerial refueling is considered to be a promising approach to reduce fuel burn and thus CO2 emissions of civil commercial aviation. Within a European research project it shall be evaluated if an aerial refueling maneuver can comply with civil airworthiness and safety standards. To substantiate this, detailed simulations are required. This paper presents a high fidelity aerial refueling boom model for simulation and boom controller design in MATLAB/SIMULINK. The boom is assembled from point masses and pipes, which are considered rigid bodies with individual inertia tensors. Instead of manually deriving equations of motion of the multi-body system (e.g. using the Newton-Euler method), the commercial SimMechanics Simulink toolbox is utilized, whereby still maintaining auto-code and real-time capability. To enable the simulation of a complete aerial refueling maneuver, a receptacle model is introduced and methods are described to take the interaction between the boom nozzle and the receptacle into account, including guidance of the boom tip towards the receptacle and constraint forces acting while the boom tip is coupled with the receptacle.
