Airfoil transformation mechanism of submarine aircraft

Abstract

The invention relates to an airfoil transformation mechanism of a submarine aircraft. A motor is connected in a fuselage, the motor is connected with a screw rod, the screw rod is parallel to the longitudinal axis of the fuselage at the center of the fuselage, a sliding block is connected to the screw rod, the inner section of a back beam of airfoils is in rigid connection with the sliding block, the inner section of the back beam of the airfoils is connected with the outer section of the back beam of the airfoils through a rotating shaft, a front beam of the airfoils is parallel to the back beam of the airfoils, the inner section of the front beam of the airfoils is connected with the wall of the fuselage, and the outer end part of the front beam of the airfoils and the outer end part of the back beam of the airfoils are connected through a front half section wing rib and a back half section wing rib. The airfoil transformation mechanism of the submarine aircraft has the technical effects that symmetrical wing-shaped hydrofoils arranged below the fuselage can produce downward lifting force during submerging, thereby ensuring the submerging requirement of the submarine aircraft and playing a role like a skid type landing gear when the submarine aircraft takes off from the water surface.

Description

technical field [0001] The invention relates to a wing conversion mechanism, in particular to a diving aircraft wing conversion mechanism. Background technique [0002] A diving plane is an aviation vehicle that can fly in the air and dive underwater. The concept of diving aircraft was first proposed during World War II, because the technical conditions at that time failed to overcome the key difficulties of diving aircraft. In the 1860s, the United States developed the world's first diving plane. The pilot drove him to complete the test flight mission. Although he realized two operating modes of diving and flying, he failed to solve the key problems such as materials and wings. The problem caused his technical parameters to fall short of the Navy's requirements and he was forced to stop research. Recently, the U.S. Advanced Planning Bureau re-proposed the plan of the diving aircraft. They summarized the key difficulties in the development of the diving aircraft, and one ...

AI Technical Summary

Problems solved by technology

[0006] Because the wing of the diving plane is relatively large, if the ordinary rigid retractable wing is used, the lateral dimension of the aircraft fuselage will be large to accommodate the retracted wing, which is not conducive to the underwater navigation of the diving plane.

However, when the ordinary folding wing method is adopted, the cross-sectional area of ​​the aircraft does not decrease, and the resistance is too large when diving underwater.

Although the common inflatable wing can effectively solve the problem of wing shrinkage, its skin stiffness is limited, and the air velocity and pressure it can withstand is very small, which cannot meet the flight requirements of diving aircraft.
