Multiphase computational fluid dynamics simulation of an amphibious aircraft hull The CFD sweeps were performed over speed and angle of attack to produce surrogate models for the hydrodynamic coefficients of a supercavitating hydrofoil, capturing the water volume fraction around the wetted section. Water volume fraction around a super-cavitating hydrofoil section Surrogate contours of hydrofoil force and moment coefficients These surrogates were used in a water-takeoff analysis that coupled the hydrofoil, hull, and aircraft aerodynamic loads, over which the hydrofoil incidence and span were optimized to minimise takeoff distance. https://godot-bloggy.xyz/project/aerospace-education/ Mon, 01 May 2023 00:00:00 +0800 https://godot-bloggy.xyz/project/aerospace-education/ This work is an interactive, computational platform for aircraft design designed to be used as an instructional tool: AeroFuse. Used at The Hong Kong University of Science and Technology, and Imperial College London. Implemented geometry, aerodynamics (vortex-lattice), structures (beam-element), propulsion (blade-element momentum theory), and flight dynamics (rigid-body integrators) for coupled analyses. Enabled adjoint-based solutions of inverse and optimization problems between disciplines with automatic differentiation. eXtended Design Structure Matrix of features in AeroFuse AeroFuse couples the disciplinary solvers into a single differentiable model, so complete aircraft configurations can be analyzed and optimized from one interface for conceptual and preliminary design.
