• Aerocartographer — A specialist in creating maps and topographic plans based on aerial photographs obtained from airplanes or drones; a high-precision optical apparatus used in photogrammetry to trace contour lines and planimetric details through the stereoscopic rendering of aerial photographs.
• Aerocell — A porous, insulating, and ultra-light material characterized by a cellular structure in which the liquid phase of a gel has been completely replaced with a gas (usually air) without the solid network collapsing. It is widely used in industrial thermal insulation, the aerospace industry, and construction due to its extremely low thermal conductivity.
• Aerospace — Relating simultaneously to airspace (atmospheric) and cosmic space (extra-atmospheric); located within these spaces or adapted to operate in both environments. The term describes technologies, vehicles, research missions, or related industries that integrate classical aviation and orbital or interplanetary spaceflight.
• Aerodyne — Any aircraft heavier than air, whose support and lift in the Earth's atmosphere are provided exclusively by the dynamic forces exerted by air on its lifting surfaces (fixed wings or moving rotors) during travel. The classification includes airplanes, helicopters, gliders, and drones, representing the opposite of aerostats.
• Aerodyne — A general or historical technical term used to designate any aircraft heavier than air (such as airplanes, helicopters, or gliders), whose support and lift in the atmosphere are provided exclusively by aerodynamic forces generated by the relative motion of its lifting surfaces (wings, rotors) in contact with the airflow. It represents the opposite of aerostats (balloons, zeppelins), which float based on Archimedean buoyancy.
• Aerodynamic — Relating to aerodynamics, concerning the motion of air and gases relative to solid bodies; having a fluid and optimized geometric shape, specially designed to minimize the drag resistance opposed by air during movement. It is widely applied in the design of aircraft, high-speed vehicles, and high-performance sports equipment.
• Aerodynamics — A branch of fluid mechanics that studies the laws governing the motion of air or other gases, as well as the forces exerted by them on solid bodies in relative motion to them. This scientific field governs the design of aircraft, rockets, and terrestrial vehicles by optimizing lift and drag forces.
• Aerodynamicist — An engineer or researcher specialized in the field of aerodynamics; a specialist who deals with the study, design, optimization, and testing of the behavior of solid bodies (aircraft, cars, rockets) moving through airflows or gases. This activity includes the use of advanced computer simulations and experimental tests in wind tunnels to reduce drag resistance.
• Aerodynamicist — The feminine form for the term aerodinamician; a female engineer or researcher specialized in the study of aerodynamic forces, the design of aerodynamic profiles, and the optimization of airflows for various vehicles, aircraft, or industrial structures through computational or experimental methods.
• Air duct — A large-sized pipe, structural tube, artificial channel, or complex technical installation specially designed for capturing, transporting, conveying, or distributing air masses or other gases within an industrial, mining, or urban ventilation system. The term can also conceptually describe a secured aerial corridor intended exclusively for the controlled transit of certain pneumatic flows.
• Avionics — A specialized branch of applied electronics and aeronautical engineering dealing with the design, manufacturing, installation, and maintenance of electronic systems and equipment used on board aircraft and rockets (navigation systems, communications, autopilot, radars, and cockpit sensors).
• Air filter — A technical device or industrial installation designed to retain impurities, dust, pollen, or other suspended particles in the air, ensuring the purification of the gas stream before it enters a room or an internal combustion engine. In ecology, the term also applies to biological systems for natural atmospheric filtration.
• Airbrake — A mobile aerodynamic device (retractable lifting surface, flap, or spoiler) mounted on the wings or fuselage of an aircraft or space vehicle, designed to be deployed into the airflow in order to increase drag resistance and rapidly reduce movement speed.
• Wind turbine — A complex technical installation (wind turbine) consisting of a bladed rotor, a speed multiplier, and an electrical generator, structurally designed to capture the kinetic energy of the wind and transform it directly into useful electrical energy. It represents the fundamental pillar of modern wind power plants destined for clean and renewable energy production.
• Hovercraft — A self-propelled amphibious vehicle (hovercraft) capable of moving at a low altitude above water, land, swamps, or ice, by generating a continuous layer of compressed air beneath its hull (air cushion) which cancels its direct friction with the ground surface.
• Aeromechanics — A branch of fluid mechanics that studies the equilibrium and motion of air or other gases, as well as the mechanical behavior of solid bodies immersed in them or in relative motion to them. This major scientific field is structurally subdivided into aerostatics (the study of gases in equilibrium) and aerodynamics (the study of gases in motion).
• Airmobile — As an adjective, it describes military forces, equipment, or tactical units capable of being rapidly transported and deployed through the air using aircraft (especially helicopters); as a neuter noun, it represents a conceptual or experimental hybrid vehicle designed to drive on roads and fly in airspace.
• Female aeromodeller — A woman who practices aeromodelling; an enthusiast or competitive athlete specialized in assembling, structurally calibrating, and radio-controlling scale model aircraft. Her activity combines the engineering rigor of construction with the fine reflex skills required to pilot the devices during technical demonstrations or specialized championships.
• Aeromotor — A mechanical device, motor, or complex technical installation that transforms the kinetic energy of air currents or wind into directly usable mechanical energy or electrical energy. In a broad structural sense, the term includes everything from high-power modern wind turbines to traditional windmills or pneumatic motors driven by compressed air.
• Aeronautical — Belonging to aeronautics or relating to aerial navigation, as well as the study, design, construction, and operation of aircraft. This term describes structural, regulatory, industrial, or scientific elements essential for vehicle flight within Earth's atmosphere, ranging from airplanes and helicopters to complex propulsion and control systems.
