Book Synopsis Multi-Slot Film Cooling of Supersonic Aircraft Using Air as a Coolant by : John I. Erdos
Download or read book Multi-Slot Film Cooling of Supersonic Aircraft Using Air as a Coolant written by John I. Erdos and published by . This book was released on 1974 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study evaluates multi-slot film cooling using air as an active coolant for thermal protection of aircraft surfaces under conditions of steady-state (cruise) operation at supersonic speeds and low to moderate altitudes. In-flight refrigeration of captured atmospheric air using a turbocooler, as described, is assumed to be the only practical means of providing the required continuous supply of cold air. Therefore the properties of the coolant have been described in terms of the vehicle flight conditions and the efficiency of a turbocooler. A computer program has been developed based on the described analysis which determines the slot locations necessary to protect a surface to a specified maximum adiabatic wall temperature at a given set of primary flow conditions.

Book Synopsis Comparison of Effectiveness of Convection-, Transpiration-, and Film-cooling Methods with Air as Coolant by : Ernst Rudolf Georg Eckert
Download or read book Comparison of Effectiveness of Convection-, Transpiration-, and Film-cooling Methods with Air as Coolant written by Ernst Rudolf Georg Eckert and published by . This book was released on 1953 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Various parts of aircraft propulsion engines that are in contact with hot gases often require cooling. Transpiration and film cooling, new methods that supposedly utilize cooling air more effectively than the conventional convection cooling, have already been proposed. The present report presents material necessary for a comparison of the cooling requirements of these two new methods with conventional convection cooling. Correlations that are regarded by the authors as the most reliable today are employed in evaluating each of the cooling processes.

Download or read book FILM COOLING IN SUPERSONIC FLOW. written by R. J. Goldstein and published by . This book was released on 1963 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of injecting a secondary gas stream at a rearward facing slot into a supersonic air flow was examined. A small Mach 3 wind tunnel was constructed and initially tested with no step present. A slot permitting injection of a secondary gas, parallel to the main air flow, at the wall was then installed. The step height is 0.121 in. with a slot opening of 0.064 in. The secondary gas can be heated and its flow rate varied. Air is the secondary fluid used in the experiments described herein. The absolute injection temperature is between 1.04 and 1.20 of the primary stream total temperature. The ratio, M, of the mass velocity in the secondary stream to that in the primary stream is in the range from zero to 0.16, corresponding to a maximum Mach number of 0.95. Schlieren photographs are presented and static wall pressure and adiabatic wall temperature measurements are described. The film cooling effectiveness is found to stay close to the value one for a distance of approximately 8 slot heights and to fall off rapidly downstream from this point. (Author).
