BOUNDARY LAYER CONTROL SYSTEM

摘要

A boundary layer control system includes a boundary layer separating portion that separates a boundary layer of an airflow at an underside of a body of a moving object from a main flow of the airflow, and an ejecting portion that ejects fluid in a state different from that of the boundary layer and the main flow, between the boundary layer and the main flow that have been separated by the boundary layer separating portion. This boundary layer control system is characterized in that boundary layer and the main flow are reliably separated by the fluid in a state different from that of the boundary layer and the main flow, so the percentage of the main flow that is slowed down (i.e., reduced in velocity) by the boundary layer is reduced.

1. A boundary layer control system comprising:
a boundary layer separating portion that separates a boundary layer of an airflow at a surface of a body of a moving object from a main flow of the airflow; an ejecting portion that ejects fluid in a state different from that of the boundary layer and the main flow, between the boundary layer and the main flow that have been separated by the boundary layer separating portion; and a suction portion that is provided behind the boundary layer separating portion in a longitudinal direction of the moving object, and sucks in fluid included in the boundary layer, wherein the ejecting portion ejects the fluid sucked in by the suction portion, between the boundary layer and the main flow.
