چکیده
Abstract The entry vehicle for the Tianwen-1 mission successfully landed on surface of Mars at 7:18 AM BJT May 15, 2021. This successful landing made China first country to orbit, land, and release a rover in their attempt exploration. guidance, navigation, control (GNC) system plays crucial role entry, descent, (EDL) phases. study focused attitude component GNC design. EDL phase can be divided into several sub-phases, namely angle attack phase, lift parachute descent powered phase. Each sub-phase has unique requirements challenges. paper introduces key aspects designing controllers each Furthermore, flight results are presented analyzed.

متن کاملHypervelocity Aeroheating Measurements in Wake of Mars Mission Entry Vehicle
Detailed measurements of aerodynamic heating rates in the wake of a Mars-Pathfinder configuration model have been made. Heating data were obtained in a conventional wind tunnel, the NASA LaRC 31" Mach 10 Air Tunnel, and in a high-enthalpy impulse facility, the NASA HYPULSE expansion tube, in which air and CO2 were employed as test gases. The enthalpy levels were 0.7 MJ/kg in the Mach 10 Tunnel,...
