Abstract

The DREAMS (Dust characterisation, Risk assessment and Environment Analyser on the Martian Surface) sensor suite is designed to investigate Martian meteorology and atmospheric electric properties at the ExoMars 2016 EDM (Entry, Descent and landing demonstrator Module) landing site. The DREAMS package will provides wind speed and direction measurement by means of MetWind hot-film anemometer and near surface temperature by means of MarsTem resistance thermometer sensor. The aim of this work is to investigate and quantify the flow distortion due to the lander and meteorological mast shape and the temperature perturbation due to the buoyant thermal plume from lander. The results of the thermal and Computational Fluid Dynamics (CFD) of the lander will be presented. Moreover, preliminary design of environmental simulation wind tunnel is presented.
