Embodiment Construction
[0022] The purpose and effect of the present invention will become more obvious by referring to the accompanying drawings to describe the present invention in detail.
[0023] The self-adaptive bionic non-smooth surface film with aerodynamic drag reduction function of the present invention comprises a substrate, a variable-volume non-smooth unit, a non-smooth unit carrier, an air-filled cavity, an air pressure lifter in the cavity, a vehicle speed signal receiver, and a controller. structured as figure 1 As shown, variable height non-smooth unit 2 adopts non-metallic materials with less rigidity, especially materials with elastic modulus lower than 100MPa, such as rubber, PVC0.007 plasticized, non-smooth unit carrier 3 and matrix 1 are Non-metallic materials with higher rigidity, especially materials with elastic modulus higher than 1GPa, such as high-pressure polyethylene and polypropylene, and the non-smooth unit 2 are sealed and bonded to each opening of the non-smooth unit...
