Abstract

The invention discloses a throat deviated pneumatic vectoring nozzle with lateral expansion. The nozzle comprises an inner runner of the nozzle. The inner runner of the nozzle comprises a nozzle inlet, a throat I, a throat I front convergence portion between the nozzle inlet and the throat I, a throat II and a throat II front expanding convergence portion between the throat I and the throat II, wherein the throat I front convergence portion and / or the throat II front expanding convergence portion has lateral expanding sections in width, and the outlet width of the throat II is greater than the inlet width of the nozzle. Therefore, the vector and non-vector properties of the nozzle are improved under the circumstance of not changing the section height of the throat II, that is, the thrust coefficient and the vector angle property of the nozzle are improved.

Description

technical field

[0001] The invention relates to a vectoring nozzle, in particular to a throat offset pneumatic vectoring nozzle with lateral expansion. Background technique

[0002] With the development of science and technology and the improvement of actual demand, more and more thrust vectoring aeroengines will be used in future aircraft. The core of the thrust vectoring aeroengine to realize the thrust vectoring function is the thrust vectoring nozzle. The traditional mechanical thrust vectoring nozzle has complex structure, poor reliability and troublesome maintenance. Therefore, it is imminent to develop a thrust vectoring nozzle with simple structure, light weight and good maintainability.

[0003] At present, the fluid thrust vectoring nozzle has gradually become the research focus and research focus of various countries due to its simple structure and light weight, and will enter engineering applications in the near future.

[0004] The throat offset pneumatic vec...
