Tailfin: meaning, definitions and examples
✈️
tailfin
[ teɪlˌfɪn ]
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.
Word origin
The term 'tailfin' combines two elements: 'tail,' which refers to the rear part of an aircraft, and 'fin,' which is derived from the Middle English word 'finne,' meaning a wing or a limb of a fish, indicative of its function in stabilizing movement. The concept of the tailfin emerged with the early developments of aviation in the early 20th century as aircraft designers sought to enhance stability and control. The evolution of tailfins has paralleled advances in aerodynamics and the understanding of flight mechanics, leading to their standardization in modern aircraft design. Over time, the shape and size of tailfins have diversified, reflecting changes in design philosophy and technological innovations.
