Modelling Vega's launch

ESA's Propulsion and Aerothermodynamics division investigated the impact of the Vega engine plume at the moment of launch from the concrete surroundings of its ELA-1 pad, as its solid rocket motor produced a shower of burning propellant particles. A model of the pad, including the flame trench intended to vent this exhaust away, was created along with a model of Vega itself.
