For maintaining an optimum value of thrust in a wide range of altitude, a flow separation position control system is available. Using the system, the problem of overexpanded nozzle area decreases and optimum thrust value is maintained at low altitude. The computations of thrust coefficients of nozzles with the flow separation position control system are presented and the effects are shown in figures., 資料番号: NALTR0447000, レポート番号: NAL TR-447}, title = {ロケットノズルの剥離位置制御}, year = {1976} }
