A delta wing is a wing shaped in the form of a triangle. ... This also improves stall characteristics and can benefit supersonic cruise in other ways.
A stall strip is a small sharp-edged device that, when attached to the leading edge of a wing, encourages the stall to start there in preference to any other location on the wing. If attached close to the wing root, it makes the stall gentle and progressive; if attached near the wing tip, it encourages the aircraft to drop a wing when stalling.
Cropped delta: wing tips are cut off. This helps avoid tip drag at high angles of attack. The Fairey Delta 1 also had a tail. At the extreme, merges into the "tapered swept" configuration. Compound delta or double delta: inner section has a (usually) steeper leading edge sweep as on the Saab Draken. This improves the lift at high angles of ...
Four basic configurations which have used vortex lift are, in chronological order, the 60-degree delta wing; the ogive delta wing with its sharply-swept leading edge at the root; the moderately-swept wing with a leading-edge extension, which is known as a hybrid wing; and the sharp-edge forebody, or vortex-lift strake.

JD-1 Dyke Delta - a small version, with 1+2 seating and fixed landing gear, used to generate and verify delta-wing and tailless-configuration flight characteristics. First flight July 1962; destroyed June 1964. [4] JD-2 Dyke Delta - an updated and enlarged version, with 1+3 seating and retractable landing gear. Debuted at Experimental Aircraft ...
Aircraft wing leading-edge extensions – annotated. A leading-edge extension (LEX) is a small extension to an aircraft wing surface, forward of the leading edge.The primary reason for adding an extension is to improve the airflow at high angles of attack and low airspeeds, to improve handling and delay the stall.
In the close-coupled delta wing canard, the foreplane is located just above and forward of the wing. The vortices generated by a delta-shaped foreplane flow back past the main wing and interact with its own vortices. Because these are critical for lift, a badly-placed foreplane can cause severe problems.
Wing loading is a useful measure of the stalling speed of an aircraft. Wings generate lift owing to the motion of air around the wing. Larger wings move more air, so an aircraft with a large wing area relative to its mass (i.e., low wing loading) will have a lower stalling speed.
