Methods of controlling equipment temperature rise in airborne compartments at supersonic flight speed are investigated. Design and performance data for expanded ram air cooling systems and various types of fuel cooled equipment cases are presented for steady state thermal operation. Other methods of controlling temperature rise are analyzed for transient thermal performance and design procedures for their applications are developed. Calculation methods are given in detail. Design procedures are illustrated by examples. The performance characteristics of the following methods are investigated 1 insulation of equipment compartment walls without cooling, 2 insulation of individual equipment items, 3 fuel jacketing of equipment compartments, 4 cooling of the compartment atmosphere by means of a central fuel cooled heat exchangers, 5 cooling of individual equipment items by installation on a fuel-cooled plate, and 6 cooling of individual equipment items by evaporation of an expendable coolant. Methods of analysis and criteria for the selection of specific means for the control of temperature rise are emphasized. The large number of variables by which each practical situation would be defined does not permit a concise description of the optimum range of conditions for the application of each method.
