The invention belongs to the field of aircraft design, and particularly relates to an early warning aircraft with an annular wing layout. The early warning aircraft with the annular wing layout comprises an aircraft body (1), an annular wing (2), an engine (3), a vertical stabilizer (4), a radar radome (5) and a horizontal stabilizer (6), the vertical stabilizer (4) is arranged on the back of the fuselage (1), the radar radome (5) is fixed above the vertical stabilizer (4), a wing root (21) of the annular wing (2) penetrates through the lower portion of a floor of a fuselage middle section (12) and bends outwards and backwards to extend to a wing middle section (22) located on the side of the fuselage middle section (12), the wing middle section (22) extends upwards and backwards to a wingtip (23) located above the fuselage, and the wingtip is connected with the radar radome above the fuselage. The aerodynamic characteristics and the cruising efficiency of the early warning aircraft are improved, the aircraft structure is optimized, the structural weight is reduced, strong infrared signals radiated by the engine are effectively shielded, and the combat effectiveness of the early warning aircraft is comprehensively enhanced.

本申请属于飞机设计领域，特别涉及一种环形翼布局的预警机。该环形翼布局的预警机包括机身(1)、环形机翼(2)、发动机(3)、垂直安定面(4)、雷达天线罩(5)及水平安定面(6)；垂直安定面(4)设置在机身(1)背部，上方固定雷达天线罩(5)，环形机翼(2)的翼根(21)从机身中段(12)的地板下方贯穿而过，向外向后弯曲延伸至位于机身中段(12)侧方的机翼中段(22)，机翼中段(22)向上向后延伸至位于机身上方的翼梢(23)，翼梢在机身上方与雷达天线罩连接。本申请提高了预警机的气动特性和巡航效率，优化了飞机结构，降低了结构重量，并且有效遮挡了发动机辐射的强红外信号，全面增强了预警机的作战效能。
