Embodiment Construction

[0027] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated.

[0028] like Figure 1 to Figure 6 As shown, the binary plug nozzle with reverse thrust function of the present invention includes a rounded square cylinder 1 and a converging section.

[0029] Specifically, the round-rotating square cylinder body 1 is connected with the front-end engine as a supporting member for the entire nozzle. One end of the rounded square cylinder 1 away from the engine is fixedly connected with one end of the converging section. The convergent segment consists of two vertical blocks (according to figure 2 Viewing direction) and left and right symmetrically arranged side wall panels 10 and two converging plates symmetrically arranged up and d...

Abstract

The invention relates to the field of engine spray pipes, in particular to a binary plug type spray pipe having a reverse thrusting function. The problem that an existing reverse thrusting device is complicated in structure and enables air flows to be easily leaked is solved. The binary plug type spray pipe having the reverse thrusting function mainly consists of a circularly-rotating square cylinder, a convergence plate, a plug cone, a connecting rod mechanism, an actuating cylinder, a fixed chute and a side wall plate. The front end of the circularly-rotating square cylinder is connected with an engine, and the convergence plate, the plug cone and the side wall plate form a spray pipe inner flowing channel. The actuating cylinder drives an adjustable wall plate through the connecting rod mechanism to achieve the reverse thrusting function. On the premise that the binary plug type spray pipe having the reverse thrusting function, the structural style and functions of a conventional binary plug type spray pipe are ensured, the binary plug type spray pipe is small in outline size, light in weight, simple in structure, high in reliability and better in air permeability, and the defects of the conventional spray pipe reverse thrusting device are overcome.

Description

technical field [0001] The invention relates to the field of engine nozzles, in particular to a binary plug nozzle with a reverse thrust function. Background technique [0002] The increase of the speed of the aircraft and the increase of the wing load will inevitably increase the take-off and landing run distance of the aircraft. In order to shorten the run distance of the aircraft and perform necessary maneuvering flight actions, a reverse thrust deceleration device is needed. The traditional grab-shaped baffle thrust reverser is relatively heavy and bears a large reverse thrust load; the baffle grid thrust reverser has many mechanical coordination parts and a complex structure, and the airflow is easy to leak, resulting in reduced engine performance. Therefore, in order to make up for the shortcomings of the traditional thrust reverser, it is necessary to design a nozzle that does not affect the conventional structure and performance of the nozzle and has the reverse thru...
