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).

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.

Book Synopsis Thermal Design for Areas of Interference Heating on Actively Cooled Hypersonic Aircraft by : R. L. Herring
Download or read book Thermal Design for Areas of Interference Heating on Actively Cooled Hypersonic Aircraft written by R. L. Herring and published by . This book was released on 1978 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerous actively cooled panel design alternatives for application in regions on high speed aircraft that are subject to interference heating effects were studied. Candidate design concepts were evaluated using mass, producibility, reliability and inspectability/maintainability as figures of merit. Three design approaches were identified as superior within certain regimes of the matrix of design heating conditions considered. Only minor modifications to basic actively cooled panel design are required to withstand minor interference heating effects. Designs incorporating internally finned coolant tubes to augment heat transfer are recommended for moderate design heating conditions. At severe heating conditions, an insulated panel concept is required.

Book Synopsis Thermostructural Behavior of a Hypersonic Aircraft Sandwich Panel Subjected to Heating on One Side by : National Aeronautics and Space Administration (NASA)
Download or read book Thermostructural Behavior of a Hypersonic Aircraft Sandwich Panel Subjected to Heating on One Side written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-17 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermostructural analysis was performed on a heated titanium honeycomb-core sandwich panel. The sandwich panel was supported at its four edges with spar-like substructures that acted as heat sinks, which are generally not considered in the classical analysis. One side of the panel was heated to high temperature to simulate aerodynamic heating during hypersonic flight. Two types of surface heating were considered: (1) flat-temperature profile, which ignores the effect of edge heat sinks, and (2) dome-shaped-temperature profile, which approximates the actual surface temperature distribution associated with the existence of edge heat sinks. The finite-element method was used to calculate the deformation field and thermal stress distributions in the face sheets and core of the sandwich panel. The detailed thermal stress distributions in the sandwich panel are presented, and critical stress regions are identified. The study shows how the magnitudes of those critical stresses and their locations change with different heating and edge conditions. This technical report presents comprehensive, three-dimensional graphical displays of thermal stress distributions in every part of a titanium honeycomb-core sandwich panel subjected to hypersonic heating on one side. The plots offer quick visualization of the structural response of the panel and are very useful for hot structures designers to identify the critical stress regions. Ko, William L.
