【Abstract】 Contoured nozzle and conical nozzles having large half angles can be designed with the characteristics of isentropic, non symmetrical flow fields in nozzle simulated numerically by CFD. The applicable range of mini thrust misalignment nozzles can thus be much extended. Experimental tests and applications on rockets show that the mini thrust misalignment nozzle exists and the new method of design is feasible.更多还原
