Helmet and use method

Abstract

A helmet having a flow guide wing and a use method are provided. The helmet includes a helmet body and a flow guide wing, where the flow guide wing is provided outside the helmet body; and in response to a shape and/or a position of the flow guide wing, when the helmet is used, the flow guide wing generates a vertical upward lift along a chord line. The flow guide wing is shaped as a symmetrical wing or a lifting wing. The flow guide wing is collapsible and/or detachable. The flow guide wing is horizontally or vertically provided. The helmet includes the helmet body and a guiding cover connected to the helmet body.
