Abstract : The results of a design study of a ceramic storage heater system for the Tripltee wind tunnel are presented. The heater is designed to supply 1500 lb/sec of air at 2000 psi and 3900 R for a period of 30 sec. Emphasis was placed on the application of improved refractory materials and shapes for the heat storage matrix to achieve a large reduction in total heater size and dust carry-over. Heating of the storage matrix with combustion products and the flow processes involved pressurizing the heater were analyzed. A heater design concept is presented and the advantages accruing from use of matrix elements specifically designed for this application are indicated. Procedures for procuring refractory elements having the requisite properties are outlined. A second Tripltee design requirement is for 5000 lb/sec of air at 400 psi and 1600 R for 30 sec. The problem of achieving this flow condition by mixing hot air from the heater with cold air was studied and a design concept for a mixer developed.
