Latest Patents

Iijima's latest patents include a riblet structure designed to minimize drag. The riblet structure features a plurality of wave-shaped riblets on its surface. Each riblet is engineered to have a smaller peak height as the angle between the ridge line and the fluid flow direction increases. Additionally, the width between peak bases decreases as the angle becomes larger. This design ensures that the angle formed between the slope of a riblet's peak and the surface remains consistent across its cross-sectional shape. The invention aims to further reduce drag, which consists of turbulent friction drag and pressure drag, in objects such as aircraft, plants, and pipelines.
