Book Preliminary Survey of Possible Cooling Methods for Hypersonic Aircraft

Download or read book Preliminary Survey of Possible Cooling Methods for Hypersonic Aircraft written by Jack B. Esgar and published by . This book was released on 1958 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Many methods of cooling the structure of an aircraft capable of flight speeds up to 18,000 feet per second were studied. Water and hydrogen stored in the liquid state appear very promising as both coolants and heat sinks. The storage and circulation of hydrogen throughout the aircraft need not be a hazard. Cooling the outer skin of the aircraft in high-equilibrium-temperature regions could probably be avoided by using a material such as silicon carbide. The internal structure could be cooled by use of a thin layer of balsa wood saturated with water. In this way tanks for storage of coolant would be avoided.

Book Design and Evaluation of Active Cooling Systems for Mach 6 Cruise Vehicle Wings

Download or read book Design and Evaluation of Active Cooling Systems for Mach 6 Cruise Vehicle Wings written by W. A. McConarty and published by . This book was released on 1971 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Active cooling systems, which included transpiration, film, and convective cooling concepts, are examined. Coolants included hydrogen, helium, air, and water. Heat shields, radiation barriers, and thermal insulation are considered to reduce heat flow to the cooling systems. Wing sweep angles are varied from 0 deg to 75 deg and wing leading edge radii of 0.05 inch and 2.0 inches are examined. Structural temperatures are varied to allow comparison of aluminum alloy, titanium alloy, and superalloy structural materials. Cooled wing concepts are compared among themselves, and with the uncooled concept on the basis of structural weight, cooling system weight, and coolant weight.

Book Numerical and Deep Learning Study of Transpiration Cooling for Sharp Hypersonic Leading Edge

Download or read book Numerical and Deep Learning Study of Transpiration Cooling for Sharp Hypersonic Leading Edge written by Danny Ko and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent escalating interest in the development of highly maneuverable hypersonic vehicles demands sharp leading edges. However, sharp leading edges induce severe aerothermal conditions where conventional passive or ablative thermal protection systems fail to protect the leading edge. This dissertation investigates transpiration cooling employing oxide coolants as an alternative system to thermally protect sharp leading edges. This dissertation studies two primary objectives that collectively assess the viability of transpiration cooling. The first objective is to characterize the performance of transpiration cooling for various coolant properties, flight conditions, and leading edge radii. We use semi-analytical boundary layer model to predict the surface temperature, evaporative mass flux, and boiling limit of the system. Our findings do not readily align with an optimal set of material properties for transpiration cooling. Instead, certain coolant properties are more appropriate for various flight conditions and leading edge sizes. The second objective is to characterize the liquid coolant flow through porous media for various hypersonic aerothermal conditions. We experimentally and numerically obtain the permeability of representative silicon carbide foams to estimate the necessary pressure gradient and assess the self-pumping capability of various coolants to meet the mass flow rate demands at the surface. We then utilize computationally efficiency deep learning models to characterize the porous media at the pore-scale to facilitate the design of the microstructures of porous leading edge. Our two numerical frameworks cohere both external and internal aspects of the system to evaluate the performance of transpiration cooling and optimize the coolant properties to effectively protect sharp leading edges, which are paramount for highly maneuverable hypersonic vehicles, for various hypersonic applications.
