Abstract:Reverse design method based on given wall pressure distribution was proposed for the shortcoming of traditional design method of asymmetrical nozzle. The reverse design program of expansion surface was obtained, and optimization method was used to find the wall pressure distribution with better comprehensive performance. Comparisons were made between the nozzle based on given wall pressure distribution and maximum thrust nozzle. The result showed that: the thrust coefficient of the nozzle decreased by 0.102% than that of maximum thrust nozzle, while the lift and pitch moment increased by 2.295% and 15.774% respectively when flow was fully expanded, verifying the design method and providing an efficient design approach for asymmetrical nozzle. © 2017, Editorial Department of Journal of Aerospace Power.
