Problems solved by technology

The traditional vector nozzle can realize the adjustment of the nozzle throat area and the vector deflection function, but it cannot realize the low infrared radiation intensity value of the engine, and the stealth effect is poor
The S-curved binary nozzle with a fixed structure can completely shield the high-temperature components inside the engine, and has good infrared stealth performance, but it cannot satisfy the adjustment of the nozzle outlet area and the vector deflection function of the engine under different working conditions.

Embodiment Construction

[0030] 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.

[0031] Such as Figure 1 to Figure 3 As shown, the present invention provides an S-curved binary nozzle with a vector deflection function, including a cylindrical body 1 , a circular square 2 , an S-curved body 3 , a nozzle outlet adjustment mechanism and a side wall 7 .

[0032] The front end of the cylinder body 1 is connected with the engine as a supporting member for the entire nozzle.

[0033] The rounded square 2 (also the cylinder body) is the transition section between the circular section and the rectangular rounded section. The front end of the rounded square 2 is sealed with the rear end of the cylindrical barrel 1, and the rear end of the rounded square 2 ...

Abstract

The invention relates to the field of aeroengine nozzles, in particular to an S-curved binary nozzle with a vector deflection function. The nozzle includes a cylindrical barrel, a rounded square, an S-curved barrel, a nozzle outlet adjustment mechanism and a side wall; the rounded square front end is connected with the cylindrical barrel, the rear end is connected with the S-curved barrel, and the rear end of the S-curved barrel The nozzle outlet is connected with a nozzle outlet adjustment mechanism; the upper adjustment plate and the lower adjustment plate of the nozzle outlet adjustment mechanism are respectively hinged at the rear end outlet of the S-curved cylinder body; the side wall is fixed at the rear end outlet of the S-curved cylinder body; The actuator drives the upper adjustment plate to connect, and the lower actuator drives the lower adjustment plate; the S-curved binary nozzle with vector deflection function of the present invention can realize the adjustment of the outlet area of ​​the nozzle and vector deflection under different working conditions of the engine The function makes up for the defect that the existing S-bend nozzle is not adjustable, and at the same time takes into account the advantages of simple structure, light weight and high reliability.

Description

technical field [0001] The invention relates to the field of aeroengine nozzles, in particular to an S-curved binary nozzle with a vector deflection function. Background technique [0002] With the continuous improvement of aircraft's requirements for engine stealth and maneuverability, the engine is required to have good infrared radiation characteristics and a large throat adjustment range, and at the same time achieve a certain angle of vector deflection. The traditional vectoring nozzle can realize the adjustment of nozzle throat area and vector deflection function, but it cannot realize the low infrared radiation intensity value of the engine, and the stealth effect is poor. The S-curved binary nozzle with a fixed structure can completely shield the high-temperature components inside the engine and has good infrared stealth performance, but it cannot meet the adjustment of the nozzle outlet area and the vector deflection function of the engine under different working co...
