Full scale thermal simulator development for the solar probe plus thermal protection system
Solar Probe Plus (SPP) is a NASA mission that will go within ten Solar Radii of the sun. One of the crucial technologies in this system is the Thermal Protection System (TPS), which shields the spacecraft from the sun. The TPS is made up of carbon-foam sandwiched between two carbon-carbon panels, and is approximately eight feet in diameter and 4.5 inches thick. At its closest approach, the front surface of the TPS is expected to reach 1200°C, but the foam will dissipate the heat so the back surface will only be about 300 ...

Development of the solar probe plus spacecraft thermal protection system (TPS) thermal simulator-subscale testing
The NASA’s Solar Probe Plus spacecraft must endure extreme heat loads while passing near the Sun. Due to its high incident heatload and temperature, the spacecraft Thermal Protection System (TPS) must be simulated using a custom thermal simulator during spacecraft thermal vacuum testing. As part of the development of the TPS thermal simulator, subscale testing was performed. The design, testing, results and lessons learned are described in this paper. Especially useful are the design aspects needed to achieve the high ...
