Anti-dragging device with vortex forming anti-dragging shell pieces

Abstract

The invention provides an anti-dragging device with vortex forming anti-dragging shell pieces. The anti-dragging device is mainly composed of installation fixing bases, shuttle-like protrusions, long-strip-shaped protrusion stripes, installation fixing devices with shuttle-shaped protrusion stripes and the vortex forming anti-drag shell pieces manufactured or installed and fixed on the outer sides of the former parts. The anti-dragging device is characterized in that the installation fixing devices are manufactured or installed and fixed on the outer surfaces of airplanes, guided missiles, torpedoes, space rockets and submarines and the outer surfaces of the portions, below the water surface profile, of high-speed surface ships; the vortex forming anti-drag shell pieces (1,18-25) which are separately arranged in parallel or arranged in parallel in a stripe mode are manufactured or installed and fixed on the outermost portions of the installation fixing devices or the top near portions of the outer sides of the installation fixing devices, and inner and outer gas and liquid moving separation plates (2) can be further manufactured or installed and fixed between the adjacent vortex forming anti-drag shell pieces (1.18-25) which are in different rows. Thus, through the anti-dragging technology, the advantages of being simple in structure, wide in application range and excellent in anti-dragging effect are achieved.

Description

Technical field: [0001] The invention relates to a drag reduction method applicable to the manufacture and use of the outer surfaces of aircraft, missiles, space rockets, torpedoes, submarines and surface warships. Background technique: [0002] Nowadays, various aircrafts, missiles, space rockets, torpedoes, submarines, and surface ships need to reduce drag during movement, and the most important thing is to adopt a streamlined or streamlined body shape. However, due to the continuous improvement of this technology for many years, development, as well as repeated practical application and improvement, such technology has basically matured and finalized, and there is little room for further improvement. Therefore, in order to further significantly reduce the movement resistance of these aircraft ships, it is necessary to consider seeking other non-current Line shape drag reduction mechanism. Invention content: [0003] The object of the present invention is to propose a b...
