WIND TUNNEL, installation in which there is an air flow for experimental study of the phenomena originating at an airflow of solids, primarily flight vehicles and their parts. In a wind tunnel investigate models, and sometimes and full-scale objects, determining the forces originating, napr., at flight of airplanes, missiles; locate their optimal forms, etc.

AERODYNAMIC DRAG (drag), force, with which gas (napr., air) acts on a body driving in a nem. The aerodynamic drag is directed always aside, counter speeds, and is one of components of a full aerodynamic force.

AERODROME (from aero... And grech. dromos - trot race, a place for trot race), the ground area with an airspace, structures and the equipment, ensuring take-off, planting, disposition and service of airplanes, helicopters and gliders. See also the Airport.

AEROSOLS (from aero... And sols), the disperse systems consisting from fluid or solids, located in suspension in a gaseous medium (it is routine in air). To aerosols concern, napr., smokes, fogs{mists}, a dust, a smog. By the way an aerosol incinerate{consume} fluid and powdery fuel, put paint coatings, use toxic materials, medicinal preparations, perfumery items, etc.

AEROSOL GENERATOR, the machine for education by a thermomechanical way of aerosols of pesticides and their dispersions with the purposes of externination of pests of agricultural crops, wood and fruit plantings, and also for a disinfection of agricultural storehouses and livestock barns.

AEROSOLTHERAPY, inhalation of aerosols primarily medicinal substances for prophylaxis and treatment of diseases of a respiratory organs.

AEROIONOTERAPIJA, treatment by conducting air of inflammatory diseases of the wind - pipes, sluggishly healing wounds, ulcers, etc. Can be general and aboriginal (an air direct on a wound, a ulcer).

AEROCLIMATOLOGY, the section of a climatology investigator climatic conditions in a troposphere and the lower stratosphere (up to an altitude of 25 kms).

AEROLITE, the obsolete title of a stone meteorite.

AEROLOGY (from aero... And... logija), the section of meteorology investigator physical processes and the phenomena in a loose atmosphere (is higher than a ground layer) and methods of their probe.

AEROMAGNETOMETER, the device for measurements of a magnetic field of the Earth from a flight vehicle (including from a satellite). Distinguish ferroprobe, proton and quantum aeromagnetometers. See. The magnetometer.

AEROMECHANICS, the section of mechanics investigator balance and motion of gaseous mediums and mechanic influences of these mediums on solids submersed in them. It is sectioned into aerodynamics and aerostatics.

AERONAUTICS, the same, that an aerostation.

AERONOMY (from aero... And grech. nomos - the law), studies high layers of an atmosphere where the dissociation of atmospheric gases and their ionization are essential. Research techniques - rocket-propelled and satellite atmospheric sounding, overseeing by a wave propagation, spectral analysis.

AERO-OTITIS (from aero... And an otitis), disease of a middle ear which can be advanced at differentials of a barometric pressure (in flights, in an altitude chamber): sensation zalozhennosti, a pain, sometimes hum in an ear.

AEROPA, in the Grecian mythology daughter Katreja, the grand daughter kritskogo tsar Minosa. Has married tsar of Argos Plejstena, then for his{its} brother Atreja. Has given rise from latter Agamemnona and Menelaus.

AIRPLANE (from aero... And an armour. planum - a plane), the obsolete title of an airplane.

AEROPONIKA (from aero... And grech. ponos - activity) (air crop), a propagation without soil in a moist air. Roots periodically{batchly} spray a nutrient solution. Apply in hothouses, greenhouses, on spacecrafts and so forth.

AIRPORT (air port), the transport agency consisting of air terminal, aerodrome, etc. and ensuring regular public conveyances, freights, mail a means of aircraft. Large airports have some air terminals (the Moscow airport of the Sheremetyevo, an Orly in Paris, etc.).
