The invention belongs to the technical field of aviation, and particularly relates to a supersonic civil aircraft layout. According to the supersonic civil aircraft layout, the engine nacelle is installed above the rear fuselage between the wing and the horizontal tail, the lower portion of the air inlet is shielded by the rear edge of the wing, the lower portion of the air outlet is shielded by the front edge of the horizontal tail, shock waves generated by the engine are prevented from spreading to the ground through the shielding effect of the wing and the horizontal tail, and the ground sound explosion loudness of the aircraft is effectively reduced; the engine and the hanger can perform small-angle pitching deflection around the rotating shaft in the hanger, so that the mounting angle of the engine is adjusted, and the propulsive efficiency of the engine under the non-design-point working condition is improved; the horizontal tail tip can be folded upwards to provide additional vertical tail capacity during supersonic cruising, loss of vertical tail efficiency during supersonic cruising is made up, and expansion waves generated by an engine exhaust nozzle and a horizontal tail are prevented from spreading to the ground. And the wingtip is put down during low-speed take-off and landing, so that a larger horizontal tail area is ensured, and the trimming requirement of a take-off and landing structure is met.
本申请属于航空技术领域,特别涉及一种超声速民机布局。本申请的超声速民机布局,发动机短舱安装在机翼和平尾之间的后机身上方,进气口下方被机翼后缘遮挡,排气口下方被平尾前缘遮挡,利用机翼和平尾的遮蔽作用避免发动机产生的激波向地面传播,有效降低该类飞机的地面声爆响度;发动机及挂架可绕挂架内的转轴进行小角度俯仰偏转,从而调整发动机的安装角,提高非设计点工况下发动机的推进效率;平尾翼尖超声速巡航时可以向上翻折提供额外的垂尾尾容量,弥补超声速巡航时垂尾效率的损失,同时阻止发动机尾喷管及平尾产生的膨胀波向地面传播;低速起降时翼尖放下,保证较大的平尾面积,以满足起降构型配平需求。
