A cover assembly for covering an object subjected to an airstream due to transportation
of the object in open air. The cover comprises a flexible cover adapted to fit
over the object so as to conceal a portion of the object. An aperture is provided
in the cover. A deflector is provided on an exterior surface of the cover and forward
of the aperture with respect to a direction of transportation. The deflector is
positioned such that a low pressure zone is created proximate to the aperture during
transportation of the object in the direction by an airstream being deflected by
the deflector, whereby air located between an interior of the cover and the object
being transported exhausts through the aperture to an exterior of the cover to
cause the cover to at least partially conform to the object.
