Description

Air inlet and outlet channel structure of vertical air sail Technical Field The utility model provides a channel structure, in particular to an air inlet and outlet channel structure of a vertical air sail. Background The vertical air sail device is widely applied to the fields of aerospace, ship propulsion, wind energy utilization and the like, and has the core effects of guiding airflow through a specific structure, converting air kinetic energy into mechanical energy or thrust and realizing effective capturing and utilization of energy. The conventional device is generally composed of a single vertically arranged sail body, the shape of the sail body is a flat plate or a simple arc, and air flows in from the front surface of the sail body, flows out after passing through the surface, and generates required thrust or lifting force by means of momentum change of the air flow. However, existing vertical aerosail devices suffer from significant drawbacks and deficiencies. On the one hand, the simple shape of the traditional sail body cannot effectively control the airflow, and the airflow is easy to separate on the surface of the sail body, so that a low-pressure vortex area is formed.
