Abstract

A series of works on the construction of optimal supersonic 2D asymmetric nozzles and on the investigation of their off-design regimes was carried out. The variation problem of the design of the supersonic 2D asymmetric nozzles with maximum thrust at given lift power and given size limitations was solved. The method of characteristics was used. Structures of flow and power characteristics in nozzles are numerically investigated at transonic and supersonic speeds of external flow. Power characteristics and three-dimensional phenomena of 2D asymmetric nozzles were experimentally and numerically studied
