delta3

Delta-3 is a type of delta wing aircraft configuration, characterized by a wing with a sweep angle of 30 degrees. This configuration is a compromise between the delta wing and the straight wing, offering a balance between the high-speed capabilities of the delta wing and the low-speed handling characteristics of the straight wing. The delta-3 configuration was first introduced in the 1950s and has since been used in various aircraft designs, including military and experimental aircraft.

The delta-3 wing provides good lift at high angles of attack, making it suitable for high-speed flight and maneuverability. However, it also introduces some challenges, such as increased drag and reduced stability at low speeds. To mitigate these issues, many delta-3 aircraft incorporate additional design features, such as leading-edge extensions, wing fences, or canards, to improve low-speed handling and stability.

Delta-3 aircraft have been used in various applications, including supersonic flight, high-altitude research, and experimental aircraft development. Some notable examples include the Convair F-102 Delta Dagger, the North American X-15, and the NASA X-24B. These aircraft have contributed to the understanding and development of delta wing configurations, paving the way for modern supersonic and high-speed aircraft designs.
