Abstract:
The contours of a maximum thrust nozzle are designed and calculated for different throat structures. The influence of throat curvature radius on flow coefficient, geometry efficiency, thrust coefficient, divergence loss and location of flow separation point is analyzed. The results show that the flow coefficient increases with the increase of the upstream curvature radius, the thrust coefficient and geometry efficiency decrease with the increase of the downstream curvature radius, the divergence loss decreases with the increase of downstream curvature radius in a small
