Abstract:With the quartz lamps and arc-heated wind tunnel, the high temperature supersonic flowfield was
built. A principle thermal protection specimen with a high temperature heat-pipe and high thermal conductivity graphite
was heated in this flowfield, the surface temperature distribution was measured by infrared temperature instruments.
Compared with contrastive carbon/ carbon composite material specimen, the stagnation point temperature of
high temperature heat-pipe was decreased 9. 5% as well as the cylinder surface temperature is increased 14. 6%, the
stagnation point temperature of high thermal conductivity graphite is decreased 14. 4% as well as the cylinder surface
temperature is increased 11. 4%,both of the two specimens can transfer the heat load effectively from the high heatflux
field to the lower one.
