Aeroelastic Modeling of Hose and Drogue Aerial Refueling Systems Including a Hose Reeling Mechanism

U.S. Navy aerial refueling operations commonly utilize a hose-and-drogue system to connect a receiver to a tanker aircraft. For pilot training, it is important to have a physicsbased simulation of the hose and drogue system, so that pilots are able to practice aerial refueling with realistic hose and drogue behavior in a flight simulator. A modeling, simulation and analysis software package called ARES (Aerial Refueling Simulation) has been developed to study the aeroelastic behavior of the hose and drogue during aerial refueling events. ARES has been developed in a MATLAB/Simulink environment and utilizes a detailed modeling approach for each of the relevant subsystems, including the hose, drogue and reeling mechanism. This paper introduces the ARES approach, describes the validation efforts that have been undertaken, and provides a brief analysis of the hose aeroelastic response.
