An automobile includes a main front air screen generator having a curved wall member extending rearwardly and upwardly to a crest. A central deflector plate develops an air screen in front of the vehicle and a low pressure pocket behind the curved member. The surfaces of the automobile include minute wave-shaped flutes, each including a trough which extends upwardly and rearwardly to a relatively sharp crest and then breaks downwardly and forwardly into the next trough such that any impactive air moves over the surface with engagement only at the crest portions. A screen covers the flutes on the back surfaces and curved vances extending rearwardly and upwardly may optimize the pressure condition.

In a craft adapted to be moved through a fluid and having a forward wall portion moving through and parting the fluid as the craft moves through the fluid and having a trailing portion, said forward wall portion of the craft defining a fluid impacting surface, said surface including a substantial plurality of adjacent and parallel waveshaped elongated flutes, each of said flutes extending as an elongated flute with a constant cross-section along said forward wall portion, each of said flutes having an essentially similar cross-section to that of the other flutes and having a trough portion extending upwardly and rearwardly to a crest portion developing an outwardly directed air stream, the crest portion of each flute overlying the trough portion of the flute rearwardly adjacent thereto to define a fluid pocket beneath the crest portion, said flutes being connected by a thin mounting base member, said flutes and base member being formed as an integral molded plastic element, and an adhesive attachment means securing said plastic element to said forward wall portion.
