The invention belongs to the technical field of aero-engine test run, and particularly relates to a roof hoisting type reverse thrust exhaust structure which comprises a roof steel frame, a hoisting column, a first track, a rotary driving assembly, a transport trolley, a volute support, a reverse thrust exhaust volute, an engine, a volute locking assembly, a second track and a rotary track. The two sections of rails are vertically distributed and are respectively fixed on a roof steel frame through davits, and the first rail is vertical to the air inlet direction of an engine; the transportation trolley on the rail is driven by the rotary driving assembly to rotate by 90 degrees in situ and reverse; the transport trolley can slide on the first track, the second track and the rotary track; a volute support is installed on the transport trolley and used for installing a reverse thrust exhaust volute. After the transportation trolley rotates by 90 degrees through the original position and is reversed, the engine is installed and fixed. When a reverse thrust test is not carried out, a small area is occupied, the pneumatic influence on a test room is small, and meanwhile, when the reverse thrust test is carried out, the transportation efficiency is high, and the track is accurately positioned.

    本发明属于航空发动机试车技术领域,具体涉及一种屋顶吊装式反推排气结构,排气机构包括屋顶钢架、吊柱、第一轨道、旋转驱动组件、运输小车、蜗壳支架、反推排气蜗壳、发动机、蜗壳锁紧组件、第二轨道、旋转轨道;两段轨道呈垂直分部,分别通过吊柱固定与屋顶钢架上,第一轨道垂直于发动机进气方向;通过旋转驱动组件驱动以实现轨道上的运输小车原位转90度换向;运输小车可在第一轨道、第二轨道、旋转轨道上滑动;运输小车上安装有蜗壳支架,蜗壳支架用于安装反推排气蜗壳;当运输小车经原位转90度换向后,安装固定发动机。本发明可在不进行反推试验时占用较小的面积,对试车间气动影响小,同时在进行反推试验时,运输效率高,轨道精确定位。
