A Delta wing is a type of aircraft wing design that has a triangular shape, resembling the Greek letter delta (Δ). This design allows for better aerodynamic performance at high speeds, making it popular in military jets and supersonic aircraft. The shape helps to reduce drag and improve stability during flight. Delta wings are often used in aircraft like the Concorde and the Lockheed Martin F-22 Raptor. Their unique structure allows for a larger wing area, which enhances lift and maneuverability. Additionally, delta wings can maintain control at high angles of attack, making them effective for various flight conditions.
