Abstract

Atmospheric glided re-entry is one of the main key technologies for future space vehicle applications. In this frame Pre-X is the CNES proposal to perform in-flight experimentation mainly on reusable thermal protections, aero-thermo-dynamics and guidance to secure the second generation of re-entry X vehicles. This paper describes the system principles and main aerothermodynamic experiences currently foreseen on board the vehicle. A preliminary in-flight experimentation and measurement plan has been assessed defining the main objectives in terms of reusable Thermal Protection System (TPS) and Aero Thermo Dynamics (ATD) data on the most critical phenomena. This flight aims also to take the opportunity to fly some innovative measurements. A complete system loop has been performed including the operations, ground system assessment, and visibility analysis. The vehicle re-entry point is at 120 km and the mission objectives are fulfilled between Mach 25 and 5. Then the vehicle has to pass...
