Large swing angle vector nozzle hybrid mechanism

Abstract

The invention provides a large swing angle vector jetting pipe hybrid mechanism. The large swing angle vector jetting pipe hybrid mechanism comprises a hybrid mechanism and a plate adjusting mechanism. The hybrid mechanism comprises a large ball seat, a small ball seat, a large ball sleeve, a small ball sleeve, a RPR type branch and three SPS-type branches, the big ball seat and the small ball seat are correspondingly connected with the big ball sleeve and the small ball sleeve in a ball pair mode, the two ends of the RPR type branch are correspondingly connected with the small ball seat and the small ball sleeve in a rotating pair mode, the two ends of each SPS type branch are correspondingly connected with the big ball seat and the small ball seat in a ball pair mode, and the small ball seat is fixedly connected with the big ball sleeve; and the plate adjusting mechanism comprises a cone sliding sleeve, three motors, three screws and a plurality of adjusting plates, the motors and the cone sliding sleeve are correspondingly fixedly and slidably connected with the big ball seat, motor shafts are in key connection with the screws, the screws are connected with the cone sliding sleeve in a threaded mode, and the adjusting plates are connected with the big ball seat in a rotating pair mode. According to the large swing angle vector jetting pipe hybrid mechanism, the swing angle of the vector jetting pipe can reach to 90 degrees, and the large swing angle vector jetting pipe hybrid mechanism is suitable for vertical taking-off and landing of a jet aircraft; and axisymmetric convergence and expansion movement of the vector jetting pipe can be realized by the multiple adjusting plates, and the rectification function and the sealing performance are good.

Description

technical field [0001] The invention relates to the field of aviation technology, in particular to a large-swing-angle vector nozzle hybrid mechanism for vertical take-off and landing of jet aircraft. Background technique [0002] Vertical take-off and landing aircraft reduce or basically get rid of the dependence on the runway, and only need a small flat ground to stand up and land vertically. Therefore, in war, the aircraft can be deployed in a dispersed manner, which is convenient for flexible attack, transfer and camouflage, and is not easy to be attacked. It was found that the attendance rate has also been greatly improved, and the attack on the enemy is very sudden, which greatly improves the survival rate of the aircraft on the battlefield. In addition, aircraft with vertical take-off and landing capabilities do not need special airports and aircraft carrier decks and runways, which saves expensive aircraft carrier and airport construction costs, and does not need to ...

Problems solved by technology

With the current technical strength, the technical solution of F-35B cannot be realized in the near future in China

At present, the driving structure of the domestic pneumatic vectoring nozzle is relatively complex, the rotation angle is small, the flexibility is poor, and the control is more complicated. When the rotation angle is large, the multiple palettes constituting the vectoring nozzle are difficult to achieve axisymmetric convergence and expansion adjustment, resulting in the rectification effect and The airtightness is poor, let alone the vertical take-off and landing fighter
