Problems solved by technology

Compared with traditional aircraft, the variable-sweep wing of a seaplane brings additional considerations: if the wingtip pontoons rotate with the wings, the pontoons and the water flow will form a larger angle when the aircraft is gliding on the water surface. This will result in greater drag and directional torque disturbances

Embodiment Construction

[0027]The present invention will be further described in detail below in conjunction with the drawings.

[0028]The wingtip follow-up pontoon of the variable-sweep-wing seaplane of the present invention includes a pontoon main body 1, a pontoon connection mechanism and a follow-up mechanism, such asfigure 1 ,figure 2 ,image 3 Shown.

[0029]The overall shape of the pontoon body 1 adopts a boat-shaped shell. The pontoon body 1 is axially parallel to the symmetrical plane of the fuselage 4 and is installed below the wing 5 near the wing tip, and the section of the pontoon body 1 is located at 1 / 2 of the fuselage 4 . The pontoon main body 1 is designed with a vertical connecting tube 101 for connection with the wing 5, and the pontoon main body 1 and the wing 5 are connected in a detachable manner, specifically: on the main wing beam 501 Install the float connecting mechanism 2 to connect. The pontoon connecting mechanism includes a connecting surface 201, a shaft sleeve 202 and a hollow con...

Abstract

The invention discloses a wingtip follow-up buoy of a variable swept wing water plane. The wingtip follow-up buoy of the variable swept wing water plane comprises a buoy main body, a buoy connection mechanism and a follow-up mechanism; and the buoy is located below a wing and close to the root of the wing and is connected with the wing through the buoy connection mechanism. The wingtip follow-up buoy of the variable swept wing water plane, disclosed by the invention, has the function that the buoy is always parallel to an axis of a plane body along with the change of a wing sweepback angle isrealized through the follow-up mechanism; the buoy is divided into two parts; the upper part can rotate around the wing and be connected with the follow-up mechanism; the lower part is detachable, sothat the process and use maintainability of the buoy are ensured; and the wingtip follow-up buoy is designed through a relative simple structure and very light weight, so that the buoy can always keepparallel to the plane body in a process of changing the sweepback angle by the wing, and has very strong practical application value.

Description

Technical field[0001]The invention belongs to the field of aircraft design, and specifically designs a wingtip follower pontoon of a variable-sweep wing hydroplane.Background technique[0002]Wingtip pontoons are usually used in seaplanes with ship-type fuselages to maintain the lateral stability of the seaplane when taxiing on it. Some military aircraft have higher requirements for speed, so the wings need to have a larger sweep angle during the design of the aircraft. When taxiing on the water, the resistance is relatively large, acceleration is more difficult, and the landing speed should not be too fast. The aircraft is required to have a small take-off and landing speed, which requires the aircraft's sweep angle to be as small as possible. Therefore, there is a demand for seaplanes with variable swept wings. Compared with traditional aircraft, the variable swept wing of a seaplane brings additional considerations: if the wingtip pontoon rotates with the wing, when the aircraft is...
