Which type of aircraft design is characterized by a triangular wing shape?

The delta wing design is defined by its triangular shape, which resembles the Greek letter delta (Δ). This configuration is known for its excellent aerodynamic properties, particularly at high speeds. The shape allows for significant lift-to-drag ratios, making it ideal for supersonic aircraft and facilitating stable flight at higher altitudes. Additionally, delta wings are known for their structural simplicity and strength, which helps reduce weight and improve overall performance. This design can also enhance maneuverability and reduce the risk of stalling compared to traditional wing configurations. Overall, the unique features of the delta wing shape contribute to its suitability for a variety of aircraft, especially those designed for speed and performance.
