Advanced rocket motor nozzles aspire to improve the rocket motor performance by various means or nozzles of non-conventional geometries. An experimental investigation was conducted along with CFD analysis to study the effect of changing the rocket motor nozzle cross section from round to rectangular on its ballistics performance. 收起
