Abstract

A drag reducing device for use on transport vehicles includes a delta wing having variable height and irregularly spaced undulations on an upper surface of each side of the wing. A length of each side of the delta wing is different than the length of the other wing side thereof.

Claims

1. A drag reducing device for use on transport vehicles, comprising:

a delta wing having variable height and irregularly spaced undulations on an upper surface of each side of the wing; and

wherein a length of each side of the delta wing is different than the length of the other wing side thereof.

2. The drag reducing device of claim 1 wherein a plurality of the delta wings is mounted on an air deflector wing of a tractor in a tractor trailer combination truck.

3. The drag reducing device of claim 1 wherein a plurality of the delta wings is mounted in a linear array.
