Abstract

The invention provides a novel spraying pipe which is characterized by comprising a straight section, installing bases, an actuator cylinder, rotating shafts, fixed pieces, adjusting pieces, rocking bars and installing sides.An inlet of the straight section is rectangular or round.The installing sides are rectangular or round and are welded to the inlet of the straight section.The installing bases are welded to the two opposite sides of the straight section respectively and used for installing the actuator cylinder.The fixed pieces are arranged on the portions, located on the same sides of the installing bases, of an outlet of the straight section respectively, the fixed pieces are installed on the outlet of the straight section in a welded mode, and two holes are formed in each fixed piece and used for determining the positions of the adjusting pieces.Rotation constraint exists between the actuator cylinder and the installing bases, that is, the actuator cylinder can rotate around the installing bases.One ends of the rocking bars penetrate through the holes in the fixed pieces and are inserted into the rotating shafts of the adjusting pieces, and the other ends of the rocking bars are hinged to an actuating rod.The novel spraying pipe has the advantages of being simple in structure and wide in application range, and the effect on contracting and expanding of the outlet of the spraying pipe and vector deflection of the spraying pipe is remarkable.

Description

technical field [0001] The invention relates to the design field of an aeroengine nozzle, in particular to a novel nozzle. Background technique [0002] It has become a very important requirement for the nozzle to realize the vector deflection and the contraction and expansion of the exhaust outlet. The current binary vector nozzle needs to use four actuators, and uses more parts such as tie rods, the structure is complex, and the maintainability and supportability are poor. Therefore, it is necessary to design a nozzle with simple structure and easy maintenance to meet the needs of the engine. Contents of the invention [0003] The purpose of the present invention is to provide a novel nozzle in order to realize the vector deflection and the contraction and expansion of the exhaust outlet. [0004] The present invention provides a novel nozzle, which is characterized in that the novel nozzle comprises a straight section 1, a mounting seat 2, an actuator 3, a rotating sh...
