초록

A device for controlling drag on a ground vehicle. The device consists of a porous skin mounted on the trailing surface of the ground vehicle. The porous skin may be separated from the vehicle surface by a distance of at least the thickness of the porous skin. Alternately, the trailing surface of the ground vehicle may be porous. The device minimizes the strength of the separation in the base and wake regions of the ground vehicle, thus reducing drag.

[ What is claimed is:] [1.]1. A method for reducing drag of a ground vehicle comprising the steps of:attaching a porous skin substantially adjacent to a trailing surface of the ground vehicle, the porous skin being substantially rigid after attachment;forming a plenum between the porous skin and the trailing surface, whereby the asymmetric character of the external trailing wake flow field of the ground vehicle is changed to a substantially steady and laterally symmetric trailing wake flow field;wherein the porous skin comprises a first porous skin porti...
