Available in PDF, EPUB and Kindle. Book excerpt: An unshielded actively cooled structural panel was designed for application to a hypersonic aircraft. The design was an all aluminum stringer-stiffened platefin sandwich structure which used a 60/40 mixture of ethylene glycol/water as the coolant. Eight small test specimens of the basic platefin sandwich concept and three fatigue specimens from critical areas of the panel design was fabricated and tested (at room temperature). A test panel representative of all features of the panel design was fabricated and tested to determine the combined thermal/mechanical performance and structural integrity of the system. The overall findings are that; (1) the stringer-stiffened platefin sandwich actively cooling concept results in a low mass design that is an excellent contender for application to a hypersonic vehicle, and (2) the fabrication processes are state of the art but new or modified facilities are required to support full scale panel fabrication.

This book was released on 1978 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of a program to design and fabricate an unshielded actively cooled structural panel for a hypersonic aircraft. The design is an all-aluminum honeycomb sandwich with embedded cooling passages ordered to the inside of the outer moldline skin; the coolant is a 60/40 mixture of methanol/water. The panel was mass optimized to sustain 20000 cycles (5000 x scatter factor of 4) of + or - 210 kN/m (+/- 1200 lbf/in.) inplane loading combined with a 6.9 kPa (+/- 1.0 psi) uniform pressure while subjected to a 136 k W/m (12 BTU/ft(2) uniform beat flux. Six fatigue specimens, of critical panel areas, were fabricated by McDonnell Aircraft Company and tested (at room temperature) by NASA. A representative test panel was not fabricated because of problems with the plotting/soldering process. The overall finding is that an actively cooled structure appears feasible for application on a hypersonic aircraft, but the fabrication process is complex and some material and manufacturing technology developments are required. Results from the program are summarized in the body of the report and supporting details are presented in several appendices. (AN).

Download or read book Internal Convective Cooling Systems for Hypersonic Aircraft written by F. M. Anthony and published by . This book was released on 1975 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parametric studies were conducted to investigate the relative merits of construction materials, coolants, and cooled panel concepts for internal convective cooling systems applied to airframe structures of hydrogen-fueled hypersonic aircraft. These parametric studies were then used as a means of comparing various cooled structural arrangements for a hypersonic transport and a hypersonic research airplane. The cooled airplane studies emphasized weight aspects as related to the choice of materials, structural arrangements, structural temperatures, and matching of the cooling system heat load to the available hydrogen fuel-flow heat sink. Consideration was given to reliability and to fatigue and fracture aspects, as well. Even when auxiliary thermal protection system items such as heat shielding, insulation, and excess hydrogen for cooling are considered the more attractive actively cooled airframe concepts indicated potential payload increases of from 40 percent to over 100 percent for the hypersonic transport as compared to the results of previous studies of the same vehicle configuration with an uncooled airframe.

This book was released on 1981 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: A 0.61 x 1.22 m (2 x 4 ft) test panel was fabricated and delivered to the Langley Research Center for assessment of the thermal and structural features of the optimized panel design. The panel concept incorporated an aluminum alloy surface panel actively cooled by a network of discrete, parallel, redundant, counterflow passage interconnected with appropriate manifolding, and assembled by adhesive bonding. The cooled skin was stiffened with a mechanically fastened conventional substructure of stringers and frames. A 40 water/60 glycol solution was the coolant. Low pressure leak testing, radiography, holography and infrared scanning were applied at various stages of fabrication to assess integrity and uniformity. By nondestructively inspecting selected specimens which were subsequently tested to destruction, it was possible to refine inspection standards as applied to this cooled panel design.
