Not all aircraft are symmetrical. Asymmetrical aircraft have a cockpit in the middle of the plane, with light and fuel tanks on either side.
Why are some planes not symmetrical? There are several reasons why this may be so, one being that some aircraft have an empty space around the cockpit area as they carry special equipment or weapons, while others may not be able to carry extra weight because of restrictions on how heavy an individual plane can be
Planes that are not symmetrical are designed for specific purposes. They are able to fly faster, jump higher or penetrate wind resistance better by creating a structural imbalance.
Rutan Boomerang
The aircraft is known for its boomerang shape wing and it’s a two-seater aircraft designed for personal use. The Rutan Boomerang is an experimental aircraft designed by Burt Rutan, which first flew in 2000.
The boomerang shape of the wing is characterized by a leading edge that is swept forward and a trailing edge that is swept back. This design allows for improved aerodynamics and maneuverability, but can also make the aircraft more difficult to control.
The Rutan Boomerang airplane is asymmetric because of its unique boomerang-shaped wing design.
NASA AD-1
NASA’s AD-1 (Ames-Dryden 1) was an experimental aircraft developed in the 1970s with the purpose of researching the aerodynamic characteristics of asymmetric or “oblique” wing configurations.
The AD-1 had a unique wing design in which one wing was mounted at a 90-degree angle to the fuselage, while the other wing was mounted at a 60-degree angle. This asymmetric configuration allowed NASA to study the effects of wing sweep on the lift, drag, and stability during flight.
The AD-1 program was successful in providing NASA with valuable data and insights into the aerodynamic characteristics of asymmetric wing configurations. The AD-1 helped NASA to understand more about oblique wing configurations and their potential benefits, such as improved aerodynamics, maneuverability, and stability.
Blohm & Voss BV 141
The Blohm & Voss BV 141 was an asymmetrical aircraft because its designers believed that the asymmetric design would offer certain advantages over a symmetric design.
One of the main advantages was improved visibility for the pilot, as the cockpit was offset to one side of the fuselage, allowing for a better field of view.
The BV 141’s asymmetry also allowed for a more balanced distribution of weight and improved stability, as the center of gravity was shifted toward the center of the aircraft.
Honeywell 757
The Honeywell 757 is not an asymmetrical plane as it is a variant of the Boeing 757, which is a twin-aisle, twin-engine commercial jetliner. The Boeing 757 has a symmetrical fuselage and wing design, which is typical of most commercial aircraft.
The Honeywell 757 is an avionics upgrade package offered by Honeywell Aerospace for the Boeing 757. This upgrade package includes modern avionics systems, such as a new flight management system, an enhanced navigation system, and an automatic flight control system, which can help to improve the performance and safety of the aircraft.
B-2 Spirit Stealth Bomber
The B-2 Spirit stealth bomber is an asymmetrical aircraft. It has a unique, flying wing design that is characterized by its curved and angled surfaces.
The B-2’s wing design allows it to have a lower radar cross-section, which makes it harder to detect by radar. Additionally, the B-2’s wing design also allows for improved aerodynamics and maneuverability, which makes it a very capable aircraft. The asymmetry of the B-2 is also seen in its engines, with one engine located on each wing’s leading edge, which helps to reduce the aircraft’s infrared signature, making it harder to detect by infrared sensors. The B-2’s asymmetrical design is a key aspect of its stealth capabilities, making it one of the most advanced and capable military aircraft in the world.

Sea Vixen
It had an unusual design feature in which one of the engines was mounted in a pod above the fuselage and the other was mounted in the fuselage.
This asymmetrical design was chosen for several reasons. Firstly, it allowed for a longer nose section which improved visibility for the pilot during landing. Secondly, the asymmetrical design of the engine nacelles also allowed for more efficient cooling of the engines. And finally, it also helped the aircraft to maintain balance and stability in flight.
The asymmetrical design of the Sea Vixen allowed the aircraft to have unique characteristics such as improved visibility, efficient cooling, and improved stability.
Asymmetrical Planes Nowadays
Asymmetrical planes are not commonly seen in modern commercial aircraft, but they are still used in some niche applications such as military and research aircraft. Asymmetrical designs can offer certain advantages over symmetrical designs, such as improved aerodynamics, stability, and maneuverability, but they also present certain challenges in terms of control and maintenance.
In military aircraft, asymmetrical designs are still being used in some cases, such as the B-2 Spirit stealth bomber and the X-47B unmanned combat air vehicle (UCAV). These aircraft have asymmetrical designs that allow them to have stealth capabilities, which makes them harder to detect by radar.
In research aircraft, asymmetrical designs are still being studied and used to test different flight regimes and gather data on the aircraft’s performance. NASA and other organizations continue to study the potential benefits of asymmetrical designs in order to improve the performance and efficiency of future aircraft.
However, in commercial aviation, symmetrical designs are more common as they provide better control, stability, and ease of maintenance, which are more important for a commercial aircraft that needs to be flown by non-experts and needs to have high availability.
