文摘

The theoretical generation principle of the parabolic configuration is presented. The first-order spatially accurate upwind scheme is chosen. The effects of jet operating conditions and physical dimensions are studied. The combinational drag and heat reduction scheme is effective at an AoA of 10°. Multi-objective optimization for drag and heat reduction is needed in the future.
