In our steadily advancing world, air travel has emerged as one of the predominant modes of transporting both people and goods. However, achieving economically efficient supersonic speeds for passenger aircraft has posed a significant challenge for manufacturers. The development of supersonic aircraft has been underway for more than seven decades. Delta wings stand out as a pivotal innovation in supersonic air travel, offering exceptional efficiency in lift and drag properties at high speeds. However, their efficiency diminishes at lower speeds primarily due to the elevated drag characteristics exhibited by the wing. In this project the Coefficient of Drag of a 76/40 double delta wing with and with-out modifications are numerically and experimentally analyzed. The modifications applied were Dimples and Tubercles. It was found that the results from numerical analysis and experimental analysis agree with each other. It was also found that Delta wings with Tubercles modification gave the best results in drag reduction. The Delta wing with Dimples did not cause much change.
