Jet aero-engine vector nozzle and aero-engine

Abstract

The invention discloses an jet aircraft engine vector nozzle capable of changing the direction of the jet air flow up and down and left and right, continuously adjusting the volume of the jet air flowand controlling the jet air flow through opening and closing. According to the jet aircraft engine vector nozzle, the design idea of an original jet aircraft engine vector nozzle is changed, a brand-new design scheme is adopted, the shape of the original jet aircraft engine vector nozzle is changed daringly, the process is greatly simplified compared with the process of the original design, the production and manufacturing difficulty is also greatly reduced; the novel jet aircraft engine vector nozzle is invented so that a pressure cavity can be installed on an aircraft by people, high-pressure airflow generated by the aircraft engine can be sprayed into the pressure cavity of the aircraft, then the airflow sprayed by all the novel jet aircraft engine vector nozzles connected to the pressure cavity of the aircraft is closed, opened and continuously adjusted correspondingly, so that the purpose of more easily controlling the attitude of the aircraft is achieved, and then the jet vertical-lifting aircraft which can be driven by a common person just like an automobile is produced.

Description

technical field [0001] The invention belongs to the technical field of jet aeroengines, in particular to a jet aeroengine vectoring nozzle and an aeroengine. Background technique [0002] At present, the known jet aeroengine vectoring nozzle is to set a mechanical device at the position of the tail nozzle that can control the swing of the tail nozzle up and down, so that all the high-pressure airflow generated by the engine is ejected through the tail nozzle. Up, down, left, and right directions, thereby correspondingly changing the direction in which the jet aeroengine generates thrust to the aircraft. Such aero-engine vectoring nozzle obviously has the following deficiencies: [0003] (1) The high-pressure airflow produced by each jet aircraft engine at present is all ejected through a single tail nozzle, and the air flow is huge, and the shape of the tail nozzle is all circular, so it is necessary to control the circle where the huge amount of high-pressure airflow is ej...

Problems solved by technology

[0004] (2) The current vectoring nozzles of jet aeroengines can only change the direction of the ejected airflow, up, down, left, and right, and cannot control the air flow of the vectoring nozzles or close and open the vectoring nozzles, so that the direction of the vectoring nozzles of the aeroengines The scope of use is very limited, and it is impossible to change the flight attitude of the aircraft by controlling the amount of air ejected from different vector nozzles of the aircraft

[0005] (3) At present, only one vectoring nozzle can be installed on each jet aircraft engine. It is impossible to install several pressure chambers on the aircraft, which can be closed and opened at the same time, and the jet flow can be adjusted. The vectoring nozzle that swings left and right prevents us from producing a jet-type vertical lift aircraft that is easy to change the attitude of the aircraft and easy to control
