Description

Technical Field

[0002] The vortex generator is a small aspect ratio delta wing installed vertically on the surface of the blade at a certain installation angle. It mainly includes a base plate and two wing plates fixed to the base plate. It generates strong wingtip vortices in the oncoming airflow. After this high-energy wingtip vortex mixes with the low-energy boundary layer flow downstream, it transfers energy to the boundary layer, so that the boundary layer flow field in the adverse pressure gradient obtains additional energy and can continue to adhere to the surface of the fuselage without separation, thereby allowing the blade to continue to maintain lift.

[0003] Before installing the turbine generator, the blades are generally adjusted to a plumb state; then, a line is drawn on the blade surface with a string, and the bonding area of ​​the vortex generator is marked at the drawn area and then polished. After polishing, the vortex generator is bonded. Since the drawn line is an irregular curve, there is a problem that the symmetry axis of the vortex generator and the rotation axis of the blade are no longer perpendicular during pasting, making the positioning of the vortex generator difficult.
