摘要
Abstract
The specific impulse is a comprehensive factor to evaluate the energy characteristics of solid rocket engine (SRE),and it affects the range of rocket greatly.It is relevant to the solid rocket propellant formulations and determined by the design parameters of SRE.The design pa-rameters of long-distance rocket TG-300 engine were used to discuss the effects of manufacturing tolerance from throat diameter,expansion cone half angle and expansion ratio on the dispersions of specific impulse and longitudinal distance.The results show that the effect of manufacturing tolerance from throat diameter on specific impulse is greatest,and the effect of tolerance from ex-pansion cone half angle takes the second place,and the effect of tolerance from expansion ratio is minor.The tolerance discussed in present paper should be controlled rationally in manufacture process,and the results obtained by current paper offer reference for structure design of SRE.关键词
