Embodiment 1

[0020] figure 1 The schematic diagram of the retracted state of the water skid of the seaplane with three stages of deceleration in this embodiment, figure 2 In this embodiment, the three-stage deceleration is a schematic diagram of the state of the water skid of the seaplane, combined with figure 1 with figure 2 As shown, the present embodiment provides a three-stage deceleration seaplane, which includes a fuselage 1 capable of gliding on water, wings arranged on the fuselage and power provided on the wings. device, the seaplane also includes a water skid 9 telescopically arranged under the fuselage. The section of the water skid 9 along the axial direction is similar to the hull; when the water skid 9 shrinks under the fuselage, the water skid 9 is attached to the bottom of the fuselage.

[0021] Water skids are installed at the bottom of the aircraft hull to reduce the collision between the hull and the wave surface through the sinking of the water skids when landing i...

Abstract

The invention belongs to the technical field of aircrafts, and provides a three-stage deceleration dampening water plane which comprises a plane body 1 capable of sliding on water, wings arranged on the plane body and power devices arranged on the wings, and further comprises a water pry 9 arranged below the plane body in a telescopic mode. Compared with a conventional seaplane, the water load isgreatly reduced when the seaplane lands on water.

Description

technical field [0001] The invention belongs to the technical field of aircraft, and relates to a seaplane capable of three-stage deceleration and low-speed water entry. Background technique [0002] Water load mitigation design technology is a key technology in the development of seaplanes. By reducing the landing speed of seaplanes on the water surface, it can effectively restrain the excessive hydrodynamic load of seaplanes when they land, improve the safety and reliability of seaplanes, and promote the development of seaplanes. Extended service life of aircraft. At the same time, reducing the water load during take-off and landing of the seaplane can effectively reduce the structural weight of the seaplane and improve its transportation capacity. [0003] At present, the seaplanes / amphiplanes under research in my country have relatively high landing and landing speeds on water. For example, the landing speed of the Kunlong 600 is about 180km / h, and the landing speed of ...
