The two-order response surface regression functions of the belly temperature rise of the aircraft about the nozzle pressure ratio (NPR), inflow velocity and the height of the nozzle exit were obtained by CFD method and the response surface method, and the key factors significantly affecting the belly temperature rise were also acquired. The interaction effects of NPR, inflow velocity and height of nozzle exit above ground on aircraft belly temperature rise were analyzed, and the maximum belly temperature rise in certain range working state was obtained. The study showed that when considering single factor the belly temperature rise decreased with the increase NPR, inflow velocity and the height of nozzle exit above the ground. When considering the interaction of the two factors, only height and NPR had interaction effects on the belly. When considering the two-order influence of single factor, there were two order effects of height of nozzle exit, inflow velocity and NPR. According to the maximum belly temperature rise obtained by optimization, the height of rear nozzle exit above ground was treble the diameter of rear nozzle exit, the NPR was 2, and the inflow velocity was 0 m/s. In this case, the belly temperature change was 13.92%.
