A deformable mechanism driven by memory alloy

Abstract

The invention discloses a deformable mechanism driven by a memory alloy, which comprises a driver mounting bracket (1), a memory alloy driver (2), a window wall plate (3), an actuator (4) and an aircraft casing (5). A window is provided on the aircraft casing (5), and a hollow detachable window wall plate (3) is arranged outside the window; a driver mounting bracket (1) is arranged inside the aircraft casing (5). One end of the memory alloy driver (2) is connected with the driver installation bracket (1), and the other end is connected with the actuator (4). The actuator (4) is an upturned arc at one end and is in contact with the arc structure of the aircraft casing (5); the free end of the actuator (4) protrudes to the aircraft casing (5) through the window wall (3) outside, and the free section is higher than the upper surface of the aircraft shell (5). The invention can reduce the flight-induced resistance during the flight of the aircraft at a constant speed, thereby improving the flight mileage.

Description

technical field [0001] The invention belongs to the technical field of deformable mechanisms realized by intelligent materials, and in particular relates to a deformable mechanism driven by a memory alloy. Background technique [0002] The concept of deformable mechanism has been proposed for several years, but there is still no specific deformable structure that can be applied in military aircraft. During the flight, the air flow will produce a certain flight resistance to the aircraft. At present, the structure of the aircraft is a fixed structure, that is, it cannot be deformed during the flight. Due to the existence of flight resistance, the non-deformable mechanism directly affects the flight mileage of the aircraft. In order to reduce the resistance of the aircraft during flight, it is proposed to add a deformable structure during the uniform flight stage of the aircraft to reduce the flight resistance and increase the flight mileage. How to realize the deformability ...

[0002] The concept of deformable mechanism has been proposed for several years, but there is still no specific deformable structure that can be applied in military aircraft

During the flight, the air flow will produce a certain flight resistance to the aircraft. At present, the structure of the aircraft is a fixed structure, that is, it cannot be deformed during the flight. Due to the existence of flight resistance, the non-deformable mechanism directly affects the flight mileage of the aircraft.
