Available in PDF, EPUB and Kindle. Book excerpt: A flight-weight radiative and actively cooled honeycomb sandwich panel (RACP was subjected to multiple cycles of both radiant and aerothermal heating. The 0.61-m (2 ft) by 1.22-m (4 ft) test specimen incorporated essential features of a full-scale 0.61-m (2 ft) by 6.10-m (20 ft) RACP designed to withstand a heat flux of 136 kW/m2 (12 Btu/sq. ft-sec). The panel consisted of Rene 41 heat shields, a thin layer of high-temperature insulation, and an aluminum honeycomb sandwich panel with coolant tubes next to the sandwich skin. A 60/40 mass solution of ethylene glycol/water was used to cool the panel which successfully withstood a total of 3.5 hr of radiant heating and 137 sec exposure to an M = 6.6 test stream. Heatshield temperatures reached 1080 K (1945 R), and cooled-panel temperatures reached 382 K (687 R) midway between coolant tubes. Simulation of the full-scale panel indicated that the full-scale RACP would perform as expected. The tests revealed no evidence of coolant leadkage or hot- gas ingress which would seriously degrade the RACP performance. (Author).

This book was released on 1971 with total page 924 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transpiration and convective cooling concepts are examined for the fuselage and tail surface of a Mach 6 hypersonic transport aircraft. Hydrogen, helium, and water are considered as coolants. Heat shields and radiation barriers are examined to reduce heat flow to the cooled structures. The weight and insulation requirements for the cryogenic fuel tanks are examined so that realistic totals can be estimated for the complete fuselage and tail. Structural temperatures are varied to allow comparison of aluminum alloy, titanium alloy, and superalloy construction materials. The results of the study are combined with results obtained on the wing structure, obtained in a previous study, to estimate weights for the complete airframe. The concepts are compared among themselves, and with the uncooled concept on the basis of structural weight, cooling system weight, and coolant weight.
