The residual chamber pressure was measured by using pressure gages with full ranges of 2.5 and 5 psia(0.334 and 0.668 kPa)in a high altitude simulation facility. The motor chamber pressure measured in the low pressure cell(about 3.34 kPa) was corrected to that of a vacuum. The mechanism of the residual thrust is discussed in this paper. From the scale effect of the residual thrust of a large-scale motor corresponding to the HI-3rd stage motor is predicted from the results of these experiments., 資料番号: NALTR0800000, レポート番号: NAL TR-800}, title = {固体ロケット残留推力の実験}, year = {1984} }
