Abstract
Planetary research of the solar system has been of great scientific interest for a long time. Today, thanks to the technology developed, it is a reality. The instrument that has contributed the most to planetary exploration has been the rover vehicle, whose mission is to circulate on the Mars surface to take photographs and measurements of environment parameters and to collect certain geological samples for later analysis. This work includes a study of the aerodynamic flow around a planetary exploration vehicle to determine the influence of the geometry of the exploration vehicle itself on the incident flow velocity measurements, measured by the anemometers included in its environmental station. Some experiments have been carried out with a subscaled model of the vehicle in a modified wind tunnel to simulate the very low Reynolds number of Mars in order to obtain the velocity measurements by Laser Doppler Anemometry in the zones where wind sensors are located. The results obtained show a region of space in which the velocity measurements taken by the sensors are invalid due to they are in the wake of the mast.
