Delta Wing: Meaning, Synonyms, Antonyms, Translation, Use Cases

delta wing

In today’s dictionary word search, we are going to be looking at the delta wing. We will be taking a look at what it means in aviation, what has similar meanings, and how it is used in constructing sentences.



A Delta wing is a triangularly shaped surface that a spacecraft and some supersonic airplanes use as both a wing and a horizontal stabilizer.

Certain jet aircraft have triangular shapes and sweptback wings known as the delta wing.

Also, a delta wing is an airplane wing with a swept-back triangle and a typically straight trailing edge.

It is an isosceles triangle-shaped single-wing arrangement that certain aircraft adopt.

A triangularly formed surface that certain supersonic airplanes and spacecraft use as both a wing and a horizontal stabilizer.

It is effectively a triangle, it aids in maintaining the aircraft’s stability at high speeds.














Italian –  ala a delta

French – aile delta

German – Deltaflügel

Greek – ptéryga délta


Etymology of Use

the word delta wing was first recorded within the period of 1945-1950 and was first used in 1946.





Use Cases

  • Their delta wing drone has a thermoplastic airframe skin composed of starch-based thermoplastic and a light, fuel-recyclable wooden frame.
  • The airplane’s high-placed delta wing had flat endplates and a wingspan of only 21 feet (6.4 meters).
  • The Falcon Solar takes the delta wing design, popular in military and supersonic jets like the Concorde, a step further with curved wings and a graceful, bird-like fuselage.
  • The exceptionally low wing loading (weight on the wing area) of the stubby delta wing provides enough lift while minimizing drag and maximizing maneuverability.

Frequently Asked Questions

What are the advantages a delta wing has over swept wing?

Because of the wing’s large surface area compared to its span, it can be built stronger and stiffer, and also has a greater internal volume for fuel storage. It’s favored among less expensive fighter aircraft because it’s also less expensive and simpler to construct.

Additionally, it increases the airplane’s crucial angle of attack. The flow boundary layer is reenergized by vortexes created at the leading edge of the wing, which prevents separation and stall. As a result, the wing has more stable low-speed flight characteristics.


Are they optimal for high speed?

By spinning a vortex across the wing surface, d-wings generate lift. You probably noticed the wing’s extremely thin and pointed leading edge if you’ve ever seen a delta wing. The airflow is split off by the thin front edge, which then rolls it into cone-shaped vortices. These cones lift as a result of the decreased pressure.

D-wings have a narrow design that makes it impossible to attach flaps, leading to faster takeoff and landing speeds. The takeoff and landing rolls are lengthened due to the speed requirements. Compared to other types of wings, these wings produce less lift at a given angle of attack. In particular, at low speeds, the angle of attack must be considerably increased to achieve sufficient lift.



The airplane wings are used to support the plane by air pressure, maintained beneath the wings. The larger the area, the larger the weight or the gravity force to support, the wings can support.

Normal wings are oblong rectangular. Delta wings are compact and have a larger area of the wing Just like any other wing, they are shaped so that the air passing underneath is slower and has more pressure than that air going over the top of the wing which pushes the plane up.
