Thermal protection systems for space vehicles: A review on technology . . . The idea of using a protection layer to prevent damage to interior parts of a vehicle is attributed to Robert Goddard who developed the concept of a heat shield in the late 1920's after observing the behavior of meteors entering the earth's atmosphere Several other pioneers in rocketry and space flight also wrote about this, including Tsiolkovskiy and Oberth as the concept of reusable space
The HEAT-SHIELD project — Perspectives from an inter . . . - ScienceDirect To provide perspectives from the HEAT-SHIELD project (www heat-shield eu): a multi-national, inter-sectoral, and cross-disciplinary initiative, incorporating twenty European research institutions, as well as occupational health and industrial partners, on solutions to combat negative health and productivity effects caused by working on a warmer
Heat Shield - an overview | ScienceDirect Topics A heat shield is defined as a thin sheet of material inserted between two surfaces to decrease radiant heat transfer, typically featuring low emissivities on its surfaces It is used in applications such as insulation for cryogenic fluid containers and improving temperature measurement accuracy
Study of film cooling performance of a support strut heat shield with . . . Applying this technology to the strut’s heat shield and investigating the effects of different hole types can be significant for the development of aero-engines The purpose of this paper is to explore an efficient cooling structure for the support strut heat shield and to understand the mechanisms that improve its cooling effectiveness (η)
The effects on heat and oxygen transport of different heat shield and . . . They noted that the new heat shield design, with a larger thickness, could prevent the heater from baking the crystal, while optimizing the sidewall insulation could prevent heat loss Song et al [10] compared the effects of using thinner and thicker heat shields (which they referred to as single-typed or double-typed heat shields)
Study on the influence of key structural parameters of turbine heat . . . However, overall, the heat transfer in these two cases with the heat shield inner rim closed mainly relies on thermal conduction of the fluid itself, and the convective heat transfer effect caused by natural convection is relatively weak
Numerical study of performance of flat and perforated radiant heat . . . The reduction ratios of the heat flux and temperature were obtained for the case without the heat shield and for a flat and perforated heat shield under the heat source of 25 kW m2 for various distances from the heat shield, and the results were compared with the experimental results
