摘要

This paper reports the results of finite analysis and trajectory simulation test of Metallic Thermal Protection System (MTPS). From the finite analysis, entry conditions are imposed and the through-the-thickness response is examined. From the temperature simulation test, the facility included 25 MW arc heater, mixing chamber, trajectory simulation and vacuum system etc. The rectangular supersonic nozzle with Mach number 4.3 was used in tests. The aero-heating conditions of the MTPS were simulated with flow field parameters of 750s. The results show that MTPS has good high temperature performance, the back temperature responses were attained in test and models have no breakage during the tests..

7. The oceans mediate the response of global climate to natural and anthropogenic forcings. Yet for the past 2,000 years — a key interval for understanding the present and future climate response to these forcings — global sea surface temperature changes and the underlying driving mechanisms are poorly constrained. Here we present a global synthesis of sea surface temperatures for the Common Era (ce) derived from 57 individual marine reconstructions that meet strict quality control criteria. We observe a cooling trend from 1 to 1800 ce that is robust against explicit tests for potential biases in the reconstructions. Between 801 and 1800 ce, the surface cooling trend is qualitatively consistent with an independent synthesis of terrestrial temperature reconstructions, and with a sea surface temperature composite derived from an ensemble of climate model simulations using best estimates of past external radiative forcings. Climate simulations using single and cumulative forcings suggest that the ocean surface cooling trend from 801 to 1800 ce is not primarily a response to orbital forcing but arises from a high frequency of explosive volcanism. Our results show that repeated clusters of volcanic eruptions can induce a net negative radiative forcing that results in a centennial and global scale cooling trend via a decline in mixed-layer oceanic heat content.
