Abstract

Two experimental investigations were carried out in DLR’s arc heated facility L2K using particle loaded CO<sub>2</sub>/N<sub>2</sub> flow simulating a dust storm scenario in the Martian atmosphere. Precise particle velocity measurements were performed in the shock layer of a flat-faced cylinder model during the first test campaign. Using the L2F measurement technique the particle deceleration could be measured almost down to the model’s surface for two different types of particles. In the second campaign dust erosion tests were performed. For different dust particles the influence of particle erosion on mass loss and surface degradation was measured. The measured data can be used for validation or modification of existing models for gas-particle interaction and surface erosion.
