The drag coefficient of internal flow was calculated to be 0.114, which indicates that only one third of total drag measured by a wind tunnel testing was produced by internal flow. The pressure drag derived by the computation agreed with the deviation of seven percent with that found in the experiments although the calculated frictional drag was higher than that found in experiment by about 25 percent. The pressure drag decreased as increasing Mach No. The frictional drag was not strongly affected by Mach No. Therefore the engine drag mainly consisted of frictional drag at M6 and M8 condition in the tested engine.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
