The invention belongs to the technical field of
airplane protection lifesaving, and provides an escape
canopy structure and a
canopy separation bolt throwing method. The escape
canopy structure comprises a hatch cover frame integrated with a
machine body and a hatch cover connected to the hatch cover frame in a sealed mode, wherein the hatch cover is movably connected with the hatch cover frame through a rear hinge mechanism, a plurality of separation bolt assemblies for fixedly connecting the hatch cover with the hatch cover frame are arranged on the inner side surface of the hatch cover frame, and the separation bolt assemblies are automatically separated to separate the hatch cover and the hatch cover frame when an
airplane encounters an emergency; and a throwing
rocket for throwing thehatch cover separated from the hatch cover frame is fixedly arranged on the inner side surface, which is away from the rear hinge mechanism, of the hatch cover. By means of the
impact force generatedafter the separation bolt assemblies explode, the cabin cover can be pushed to ascend, the canopy is facilitated to rotate, and interference with an
airplane body is avoided; and the hatch cover canbe thrown more timely and quickly, and a safety guarantee is provided for pilots in the escape process.
