Reusable Launch Vehicle (RLV) has validated the vertical takeoff and vertical landing reusable rocket concept through the implementation of a robust vehicle design tailored to the well-structured mission profile executed in distinct phases, varying in altitude and travel speed. This study performs an in-depth exploration of the flowfield attributes and comprehensive aerothermal analysis of the vehicle and the surrounding atmosphere. Additionally, the study of angle of attack is of paramount significance, especially during the flip manoeuvre, wherein the vehicle encounters dynamic changes in this parameter. The employment of the Reynolds Averaged Navier-Stokes (RANS) solver in conjunction with the Shear-Stress Transport (SST) k-ω model within SU2 was instrumental in conducting these analyses. The findings reveal that as the vehicle progresses to lower speeds and altitudes, the manifestation of shock and plume formation becomes less pronounced, consequently diminishing the associated aerothermal effects.
