Problems solved by technology

[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.

Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0016] like figure 1 As shown, a memory alloy driven deformable mechanism of the present invention adopts the technical solution of installing a memory alloy driver 2 and an actuator 4 inside the aircraft shell 5 . The shape memory alloy driver 2 is a shape memory alloy material. After being deformed and fixed, the memory alloy driver 2 realizes the shape memory function by inducing a material phase transformation mechanism through external conditions such as stress or temperature, that is, it can be shaped under high temperature conditions, and its shape can be realized at low temperature or normal temperature. Plastic deformation occurs. During the execution process, the actuator is actuated by means of energization and heating.

[0017] During the flight of the aircraft at a constant speed, the memory alloy driver 2 is actuated, thereby driving the actua...

Abstract

The invention discloses a deformable mechanism driven by memory alloy. The deformable mechanism comprises a driver mounting bracket (1), a memory alloy driver (2), a window wall plate (3), an actuating mechanism (4) and an aircraft shell (5). A window is formed in the aircraft shell (5), and a hollow detachable window wall plate (3) is arranged at the window; and the driver mounting bracket (1) isarranged in the aircraft shell (5). And one end of the memory alloy driver (2) is connected with the driver mounting bracket (1), and the other end is connected with the actuating mechanism (4). Theactuating mechanism (4) is in an arc shape with one end tilting upwards and makes contact with the arc-shaped structure of the aircraft shell (5). The free end of the actuating mechanism (4) extends out of the aircraft shell (5) through the window wall plate (3), and the free section is higher than the upper surface of the aircraft shell (5). Flight induction resistance can be reduced in the constant-speed flight process of the aircraft, and the flight mileage is increased.

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 ...
