DeltaTragfläche

DeltaTragfläche, also known as delta wing, is an aircraft design feature characterized by a triangular or delta-shaped wing planform. This design is distinguished by its sharp leading edge and relatively small sweep angle, typically between 60 and 80 degrees. Delta wings are known for their unique aerodynamic properties and have been employed in various aircraft types, including fighters, bombers, and supersonic aircraft.

The primary advantage of delta wings is their ability to generate lift at high angles of attack, making them suitable for high-performance aircraft. This characteristic is due to the wing's ability to create a strong vortex system, which enhances lift generation. Delta wings also tend to have a lower drag coefficient at supersonic speeds compared to conventional wings, which contributes to their efficiency in high-speed flight.

However, delta wings also have several disadvantages. They are generally less efficient at low speeds and require higher landing speeds, which can be a safety concern. Additionally, delta wings can suffer from a phenomenon known as "Dutch roll," a combination of rolling and yawing motions that can be difficult to control. This instability is more pronounced in delta-winged aircraft.

Delta wings have been used in numerous aircraft designs throughout history. Notable examples include the Messerschmitt Me 262, the Convair B-58 Hustler, and the SR-71 Blackbird. Despite their challenges, delta wings continue to be studied and employed in modern aircraft design, particularly in the development of supersonic and hypersonic vehicles.
