This paper discusses the thermal protection system (TPS) on an airframe of the Single Stage to Orbit (SSTO) with a scramjet engine. There is aerodynamic heating to the airframe during flight through the air, especially during hypersonic flight, and this paper examines ceramic tile insulation and hydrogen active cooling. The transient nature of each system was simulated along the ascent trajectory of the SSTO to the low earth orbit of 100 km. When ceramic tiling was used, a tile thickness of around 60 mm was required to protect the inside of the airframe. The highest temperature on the inside surface of the tile occurred after arrival to the orbit. The temperature on the inside surface increased with the decrease of the flight dynamic pressure. In the active cooling system, around 20% of fuel was used for airframe-cooling. Attaching thin ceramic tiling on the surface of the cooling panel reduced the cooling requirement.
