As a vehicle enters an atmosphere, it interacts with the surrounding gas. The interaction produces aerodynamic forces and moments that act on the vehicle during entry, and in the process, reduce the vehicle internal energy to an acceptable value for the deployment of a decelerator. The RCS jets will interact with the aftbody flow too, inducing different interaction phenomena that may alter both aerodynamic characteristics and aerothermodynamic environment of the backshell of the capsule. Those interactions, in some cases, could counter the RCS control authority too. The ESA study \"Preliminary design and performance verification of critical elements for guided entry thrusters\", performed by Thales Alenia Space Italia, CIRA and T4i, has the main goals to define the preliminary design of a RCS capable to control and guide a reference entry probe in the scope of the studied ESA Mars Precision Lander mission and to derive the requirements for a future test campaign in CIRA Scirocco PWT facility, to verify the performance of the designed system. The present paper will describe: *) The preliminary design of a Guided Entry Thruster System for Precision Landing on Mars, including the trade-off between different layouts *) The setup of a test campaign in CIRA Scirocco facility to verify the performance of the designed system *) The design of the test article, including the test thruster system, and the setup of the Wind Tunnel Test campaign in CIRA SCIROCCO arc jet facility to verify the performance of the flight thruster system. |
