“…Focusing on higher angles of attack, in [10], semiempirical data were interpolated for capturing unsteady regions to predict AUV performance for angles of attack up to 30 • , whereas in [11], Jorgensen's analytical formulation [12] was used to calculate the AUVs hydrodynamics in the 0 • -360 • angle-of-attack range.…”

Hydrobatic AUVs are very agile, and can perform challenging maneuvers that encompass the full 0 • -360 • flight envelope. Such AUVs can be beneficial in novel use cases in ocean production, environmental sensing, and security, by enabling new capabilities for docking, inspection, or under-ice operations. To further explore their capabilities in such scenarios, it is crucial to be able to model their flight dynamics over the full envelope, which includes strong nonlinear effects and turbulence at high angles of attack. With accurate and efficient simulation models, new hydrobatic maneuvers can be generated and control strategies can be developed. Therefore, this article contributes with a strategy to perform efficient and accurate simulations of hydrobatic maneuvers in real time. A multifidelity hydrodynamic database is synthesized by combining analytical, semiempirical, and numerical methods, thereby capturing fluid forces and moments over the full envelope. A component buildup workflow is used to assemble a nonlinear flight dynamics model using lookup tables generated from the database. This simulation model is used to perform real-time simulations of advanced hydrobatic maneuvers. Simulation results show agreement with literature and experiment, and the simulator shows utility as a development tool in designing new maneuvers and control strategies.
