tailfin
[teɪlˌfɪn ]
Definition
Context #1 | Noun
aerodynamics
A tailfin is a vertical stabilizing structure located at the rear of an aircraft or jet that provides directional stability during flight. It is designed to counteract the forces that can cause an aircraft to yaw, which is the side-to-side motion around its vertical axis. By maintaining the aircraft's directional control, the tailfin plays a crucial role in ensuring a safe and efficient flight.
Synonyms
fin, rudder, vertical stabilizer.
Examples of usage
- The plane's tailfin was damaged during the storm.
- Engineers redesigned the tailfin for improved performance.
- The aircraft's tailfin helps maintain stability during turbulence.
Interesting Facts
Etymology
- The word 'tailfin' combines 'tail,' meaning the rear part of an animal, and 'fin,' a thin structure that helps in swimming.
- First used in English around the 19th century to describe fish anatomy more accurately.
- Tailfins took on a new cultural significance in the mid-20th century with the rise of automobile design.
Science
- Tailfins in marine animals, like sharks and whales, provide thrust and lift, allowing them to navigate through water efficiently.
- In aviation, the vertical stabilizer (often mistakenly called the tailfin) helps maintain aircraft stability during flight.
- Different shapes of tailfins can influence speed; for instance, some are designed to be sleek to reduce drag.
