Throe chamber configurations were analyzed: 1) an 8-inch diameter (Ec = 2) chamber having constant width channels;2) an 8-inch diameter chamber having constant width lands;and 3) a 10-inch diameter chamber (Ec = 3) having constant width lands. Component weights, pressure drops, and nozzle performance were calculated for each configuration using experimental heat transfer data. OMS trade factors were used to convert the weights and pressure drops to equivalent specific impulse values for: 1) constant OMS inert weight, and 2) constant OMS wet (tanked) weight.nThe resulting weights, pressure drops, and performance values summarized below indicate the superiority of the constant width land over the constant width channel configuration. The 8-inch diameter chamber provides a significant equivalent performance gain relative to the 10-inch chamber based on constant OMS inert weight but a slight perform-ance loss based on wet weight.
