Add to dictionary

aerodynamics

[ˌɛəroʊdaɪˈnæmɪks ]

Definition

Context #1 | Noun

science field

Aerodynamics is the study of the behavior of air as it interacts with solid objects, like an aircraft or a vehicle. It involves the analysis of forces and the resulting motion due to the interaction of air with these objects. Understanding aerodynamics is crucial for designing efficient vehicles and structures that can minimize drag and maximize lift.

Synonyms

aerial mechanics, airflow dynamics, fluid dynamics.

Examples of usage

Origin of 'aerodynamics'

Main points about word origin

  • The word comes from the Greek words 'aero' meaning 'air' and 'dynamics' meaning 'force and movement'.
  • It first appeared in the late 19th century as scientists began to understand flight better.

The term 'aerodynamics' is derived from the Greek words 'aero', meaning air, and 'dynamics', meaning force or power. The study of aerodynamics dates back to ancient times, but it gained prominence during the early 20th century with the advent of powered flight. Early pioneers like Sir George Cayley and Otto Lilienthal laid the groundwork for understanding how air interacts with moving bodies. Over the years, the field has expanded significantly, leading to modern advancements in not only aviation but also in various engineering disciplines. Aerodynamics plays a crucial role in the design and optimization of vehicles, buildings, and various structures that must contend with air forces.
