Embodiment Construction

[0026] 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.

[0027] like Figure 1 to Figure 4 As shown, the present invention provides an adjustable S-curved binary nozzle, including a cylinder body 1 and a left wall plate 11, a right wall plate 12, an outer baffle plate, a middle baffle plate, and an inner baffle plate forming the cylinder body 1, It also includes a first pull rod 5 , a second pull rod 6 , a first actuator 7 and a second actuator 8 .

[0028] The front end of the cylinder body 1 is connected with the engine as a supporting member for the entire nozzle. In addition, the outlet at the rear section of the cylinder body 1 can be zigzag-shaped through stealth modification.

[0029] The left wall 11 and the right...

Abstract

The invention relates to the field of an aircraft engine spraying pipe, particularly to an adjustable S-shaped binary spraying pipe. The adjustable S-shaped binary spraying pipe comprises a barrel, a left wallboard, a right wallboard, a front outer baffle plate, a rear outer baffle plate, an upper middle baffle plate, a lower middle baffle plate, a front inner baffle plate and a rear inner baffle plate, and also comprises a first pulling rod, a second pulling rod, a first actuating tube, a second actuating tube and a sealing plate; the upper middle baffle plate and the lower middle baffle plate are respectively arranged between the left wallboard and the right wallboard in a hinge manner, the front outer baffle plate and the rear inner baffle plate are respectively hinged to the front end and the rear end of the upper middle baffle plate, and the front inner baffle plate and the rear outer baffle plate are respectively hinged to the front and rear ends of the lower middle baffle plate; the first actuating tube drives the front outer baffle plate and the front inner baffle plate to move, and the second actuating tube drives the rear outer baffle plate and the rear inner baffle plate to move. The adjustable S-shaped binary spraying pipe is simple in structure, fewer in moving connecting pieces, capable of driving the connected outer baffle plate, middle baffle plate and inner baffle plate to be deformed by virtue of the actuating tube and capable of realizing the mode conversion of the binary spraying pipe between the high pneumatic performance and the high stealth performance.

Description

technical field [0001] The invention relates to the field of aeroengine nozzles, in particular to an adjustable S-curved binary nozzle. Background technique [0002] The S-curved binary nozzle is one of the types of nozzles used in aero-engines. The design of the S-curved flow path makes it have excellent stealth performance in terms of infrared, radar and noise, but the aerodynamic performance of the corresponding S-curved flow path will be lower than conventional binary nozzles. In order to meet the diversified needs of future aircraft, so that the aircraft can selectively improve the stealth performance or aerodynamic performance of the nozzle, it is necessary to design an adjustable S-curved binary nozzle with a simple structure and few moving parts. Contents of the invention [0003] The object of the present invention is to provide an adjustable S-curved binary nozzle to solve the problem of low aerodynamic performance of the current S-curved binary nozzle.
