Embodiment Construction

[0023] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] refer to Figure 1 to Figure 6 , the bionic shark skin using shape memory alloy artificial muscle to laterally inject drag reducing agent, including support base 1, hardened conductive layer I2, artificial muscle expansion unit 3, hardened conductive layer II4, and imitated shark scale skin layer 5. The support base 1 is used to support and install and fix the bionic shark skin on the wall of the carrier shell, the lower surface of the hardened conductive layer I2 is fixed to the upper surface of the support base 1, and the upper surface of the hardened conductive layer II4 is connected to the imitation shark skin. The lower surface of the scale skin layer 5 is glued together, and the thicknesses of the hardene...

Abstract

The invention relates to the field of engineering bionic technology, in particular to bionic sharkskin making use of a shape memory alloy artificial muscle transversely-injected drag reducer. The bionic sharkskin making use of the shape memory alloy artificial muscle transversely-injected drag reducer comprises a supporting base, a hardened conductive layer I, artificial muscle flexible units, a hardened conductive layer II, a shark scale imitation skin layer and a drag reducer transverse injection device, wherein each artificial muscle flexible unit comprises a shape memory alloy artificial muscle spring, a pulling head, a two-section electric heating rod and a connection conductive wire, and each shape memory alloy artificial muscle spring has a certain amount of supporting strength. Compared with the prior art, the bionic sharkskin making use of the shape memory alloy artificial muscle transversely-injected drag reducer has the advantages that by the adoption of the design of shape memory alloy artificial muscle, a micro mucus secreting mechanism of the sharkskin is simulated by means of the unique material characteristic that the double-trip memory effect is presented under the driving of transformation temperature of the shape memory alloy artificial muscle, the working mode and control method of injecting a micro amount of the drag reducer are more sensitive, controllable and reliable compared with existing means, service life is guaranteed effectively, and a beneficial example is provided for the engineering bionic technology, especially the bionic drag reduction skin manufacturing technology, in the aspect of structure and function bionics.

Description

technical field [0001] The invention relates to a kind of bionic shark skin, more particularly, refers to a kind of bionic shark skin which utilizes shape memory alloy artificial muscle to laterally inject a drag reducing agent, and belongs to the field of engineering bionic technology. Background technique [0002] Effectively reducing the surface resistance of aircraft to improve speed, maneuverability, endurance and fuel efficiency is of great significance to national economy and national defense security. High-speed underwater creatures such as sharks, dolphins, and tuna undoubtedly provide humans with extremely valuable engineering bionic models. The targeted development of high-efficiency, low-resistance bionic drag-reducing skin has become a current research hotspot and difficulty. [0003] The high swimming speed of sharks is not only related to its perfect streamlined shape, but also closely related to the special micro-scale structure of its epidermis and the mucus...
