Which type of wings is known to produce less drag at high speeds?

Swept wings are designed with a significant angle to the plane's body, which effectively reduces drag at high speeds. This design helps in delaying the onset of shock waves that occur when an aircraft approaches the speed of sound. Additionally, swept wings enhance the airplane’s performance by minimizing pressure drag and improving lift-to-drag ratios during high-speed flight.

The aerodynamic efficiency gained through the swept wing design makes it a preferred choice for many high-speed aircraft, including jets. On the other hand, other wing types, while beneficial for different aspects of flight, do not offer the same advantages at elevated speeds. For example, perpendicular wings and set wings are better suited for slower speeds and provide good lift characteristics for conventional aircraft but can increase drag as speed increases. Delta wings, although quite effective at high speeds and showcasing good stability at steep angles of attack, are generally not as efficient at cruising speeds compared to swept wings.
