Abstract
The invention relates to the field of aero-engine designing, in particular to a binary spraying pipe with the reverse thrusting function. The problems that an existing reverse thrusting device is complex in structure, and air flow is prone to leakage are solved. The binary spraying pipe with the reverse thrusting function is mainly composed of a circle-to-square cylinder body, a reduction plate, a grid, movable outer covers, connecting rod mechanisms, actuating cylinders and side wall plates. The front end of the circle-to-square cylinder body is connected with an engine. In the normal air exhausting state, an in-spraying-pipe flow passage is composed of the reduction plate and the side wall plates; the actuating cylinders drive the middle section of the reduction plate through the connecting rod mechanisms to rotate to achieve the reverse thrusting function. On the premise that the reverse thrusting function is achieved, the binary spraying pipe guarantees the structural form and the functions of a conventional binary spraying pipe, the overall size is small, the structure is simple, reliability is high, convenience is brought to integration of a machine body, and the defects of a conventional spraying pipe reverse thrusting device are overcome.
