The roundnose wedge is a water-cooled holder for a 5-inchsquare test panel. The fiat Iy, el affords m some economy in specimen preparation. Currently, such specimens are tested in a large-diameter subsonic arc jet. Views of 5-inch-square specimens tested to determine performance of charring ab]ators at very low heating rates are shown in figure. A hot jet research facility, used extensively in the design and development of the reentry heat shield on the Project Mercury spacecraft. The electrically heated arc jet simulates the heating encountered by a space vehicle as it returns to Earths atmosphere at high velocities. NASA EL

results. Technical. The Arc-Jet provides the expertise to support screening, development, and validation of human-rated spacecraft thermal protection systems and robotically piloted vehicles. The Arc-Jet is a high altitude, hypersonic wind tunnel facility that uses 4 direct current (DC) rectifiers capable of producing 10 MW of electrical power to heat test gases.

Washington, DC: The National Academies Press. doi: / Recent research has been focused on the development of lower density ablators. For higher speed entries into the outer planets or their moons that. The testing capabilities (based on plasma jet torches) for TPS materials are also evidenced in Fig.
It appears that current facility does an adequate job of covering a low Earth orbit (LEO) entry (such as a shuttle return) and almost capture the Apollo lunar return peak heating point; however, they are inadequate for simulating the peak heating regions for Mars and far solar system by: 1.
Atmospheric entry is the movement of an object from outer space into and through the gases of an atmosphere of a planet, dwarf planet or natural satellite. There are two main types of atmospheric entry: uncontrolled entry, such as the entry of astronomical objects, space debris or bolides; and controlled entry (or reentry) of a spacecraft capable of being navigated or following a predetermined.
The RFP requires us to predict the thermal and mechanical response of a ceramic tile wing leading edge design under both ground test (arc-jet) and flight environments. According to Milos and Squirethe wing leading edge can be model as a inch long beam with a “U-shape cross section” having a characteristic dimension inches.
