| Abstract: | Various factors acting on the measurement of vacuum total impulse of the apogee booster for STW experimental communications satellite and uncertainties resulting from them are presented in this paper. The error sources of parameters such as thrust, pressure, vacuum pressure etc are emphatically described. The e-xperiences of engine tests at simulated altitude conditions are reviewed. The imagination and the executive ways to reduce the uncertainties in vacuum total impulse measurement are also discussed. |
