The system was modelled and simulated using Computational Fluid Dynamics (CFD)<br>using Fluent\u00ae as software, with density and pressure-based solvers to obtain its aerodynamic<br>coefficients for simulation and control purposes. A 1st and 2nd order spatial discretization was made to<br>generate the meshes with around 7.5 million elements and a Spalart-Allmaras turbulence method was<br>used. The complete Aerodynamic database will be obtained after computing the stability derivatives<br>using the Vortex Lattice Method (VLM). With the aerodynamic coefficients it\u2019s possible to load the glider<br>model in a simulation environment, developed in Matlab Simulink, and check the behaviour of the<br>aircraft in flight. Using the simulation environment and control system techniques it is possible to<br>develop a control system able to manage the vehicle in different conditions below Mach 2 until splash-<br>down. An external layer is then added to the control algorithm in order to perform a parameter<br>identification in-flight experiment when the correct conditions are obtained. The experiment is planned<br>to perform a series of doublet manoeuvres at Mach 2 and Mach 1.35. After the flight the embedded<br>sensors data will be analysed and compared to the numerical model in Simulink aiming to improve the<br>model within the limits of the experiment.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/04\/HiSST-2022-426.pdf\">Read the full paper here<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>L.
