Summary
This work outlines a design process of high-speed and high-density expansion tube flow conditions for future Mars Sample Return missions. The expansion tube must attain 10 km/s or above shock velocity through denser gas fills in shock/expansion tubes to produce higher freestream density for the subscale test models. An experimental investigation was carried out in the T6 Stalker Tunnel at the University of Oxford to examine the feasibility of generating such conditions. The experiments showed that these conditions obtained desired flow velocity and steady test-time.
