Problems solved by technology

When ice accumulates on the wing, the aerodynamic shape of the wing changes, resulting in a decrease in lift and an increase in drag. At the same time, ice accumulation on the wing will also damage the handling performance and seriously affect flight safety.

Abstract

The invention discloses a wing deicing device and a wing including the deicing device. The device is installed inside the wing and includes a base body, a magnetic vibrator, an elastic membrane, a wing skin and screws; the magnetic vibration The vibrator is composed of a coil frame, a vibrator shell, a magnetostrictive rod, an actuator rod, a coil and a disc spring; the base body is fixed inside the wing, and the magnetic vibrator is installed between the skin and the base body through the coil frame perpendicular to the base body to form a In the inner cavity of the vibrator shell, a coil skeleton and a magnetostrictive rod are installed inside the vibrator shell, and the coil is wound outside the coil skeleton. The shell of the vibrator is connected by screws, and the skin of the wing is also connected with the shell of the vibrator by screws. The invention utilizes the continuous deformation produced by the supermagnetic material in the changing magnetic field to clear the ice accumulation on the wing, has high efficiency, less energy consumption, and does not destroy the aerodynamic shape of the wing or damage the skin of the wing.

Description

technical field [0001] The invention relates to a wing deicing device using giant magnetostrictive materials, belonging to the technical field of deicing aircraft wings. [0002] technical background [0003] During the flight of the aircraft, when the aircraft body touches the supercooled water droplets in the air, there is a risk of icing on the surface of the aircraft. When ice accumulates on the wing, the aerodynamic shape of the wing changes, resulting in a decrease in lift and an increase in drag. At the same time, ice accumulation on the wing will also damage the handling performance and seriously affect flight safety. [0004] At present, the commonly used deicing methods include thermal deicing method, mechanical deicing method and chemical deicing method. purpose of ice. Contents of the invention [0005] The patent of the present invention utilizes the principle that giant magnetostrictive materials can produce telescopic deformation under the action of an exte...
