Abstract:
1. A wake disturbing apparatus reducing drag (i.e., air resistance) on an object with blunt trailing edge (e.g., a truck), the wake disturbing apparatus comprising: a plurality of disrupters, which are arranged at regular intervals along a trailing edge of the object and protrude to a predetermined height so that the vortical strength of wake occurring behind the object can be reduced and the pressure at the base surface, which has been decreased due to the wake, can be recovered; wherein the disrupters comprise: a pair of narrowing wing plates having a distance therebetween which gradually narrows toward the trailing edge of the object so that airflow therebetween can be converged and accelerated; and a pair of widening wing plates having a distance therebetween which gradually widens toward the trailing edge of the object so that airflow therebetween can be expanded and decelerated, and the pair of narrowing wing plates and the pair of widening wing plates are arranged adjacent to each other and share a common wing plate; and an angle adjustment means, which is installed at each of the disrupters and optimizes an angle formed by each pair of disrupters by adjusting the angle in consideration of airflow (or the speed of the object).
