Problems solved by technology
[0004] However, the disadvantages of the prior art are: the engine provides the front lift directly from the bleed air behind the fan, resulting in a decrease in the flow rate of the compressor and a decrease in engine power
[0005] The other one is that the structure of the engine is more complicated, the reliability is reduced, and the weight is greatly increased due to the addition of a lift fan.
And the addition of the lift fan requires power extraction on the worm gear, reducing engine performance

The invention discloses an exhaust system and an aircraft with the same. The exhaust system includes a first auxiliary lift nozzle, a second auxiliary lift nozzle, a main nozzle and a spherical vector adjusting sheet, wherein the cavity of the main nozzle is provided with a first connection hole and a second connection hole. hole; one end of the first auxiliary lift nozzle communicates with the first connection hole; one end of the second auxiliary lift nozzle communicates with the second connection hole; the spherical vector adjusting piece is hinged in the cavity of the main nozzle, and can be relatively The main nozzle turns. The exhaust system of the present application switches between providing lift and not providing lift by changing the position of the spherical vector adjusting plate, so as to realize short vertical take-off and landing of the aircraft, and has the advantages of simple structure, light weight, and is convenient for installation, manufacture, cooling and weight reduction The advantages.
Description
Technical field[0001]The present invention relates to the field of engine technology, and more particularly to an exhaust system and a aircraft having it.Background technique[0002]The shorthanding decreases that the aircraft can achieve short distance or vertical takeoff and landing, with aircraft combat reactivity, environmental adaptability, and battlefield survivability of this function.[0003]The prior art uses a thrust vector engine or a thrust engine combination with a thrust engine.[0004]However, the disadvantage of the prior art is that the engine is due to the front lift from the fans, causing the compressor flow to decrease, and the engine power is lowered.[0005]Another one has been added separately, resulting in more complex, reliability decreases, while the weight is increased. And the addition of the lift fan requires power extraction on the worm gear, reducing engine performance.[0006]Therefore, it is desirable to have a technical solution to overcome or at least mitiga...
