Aeronautics

Aeronautics is the science concerned with the study, design, and produce of flight-capable equipment, or the technique of in use aircraft. While the term accurately meaning "sailing the air" initially referred solely to the science of working the aircraft, it has since been extended to include technology, business and other aspect related to aircraft. One of the important parts in aeronautics is a branch of physical discipline called aerodynamics, which deal with the activity of air and the way that it interact with objects in movement, such as an aircraft. Aviation is a word sometimes used interchangeably with aeronautics, though "aeronautics" consists of lighter-than-air craft such as airships, while "aviation" does not.
