aeroplane (US = airplane)
aeroplane (US = airplane) BS.185, 1940: ‘A flying
machine with plane(s) fixed in flight’. Modern definition
might be ‘mechanically propelled aerodyne sustained by
wings which, in any one flight regime, remain fixed’.
Explicitly excludes gliders and rotorplanes, but could
include MPAs, VTOLs and convertiplanes that behave as
* in translational flight.
aeroplane effect Error in radio DF caused by horizontal
component of fixed aerial or trail angle of wire (arch.).
Aeropp Aeronautical message switching system.
aeropulse Air-breathing pulsejet.
aeroresonator Resonant air-breathing pulsejet.
aeros Aerobatics, plural of aero. (colloq.).
aerosat Aeronautical satellite.
aeroservoelasticity Study of aeroelasticity in aircraft
with automatic control systems.
aeroshell High-drag aerodynamic-braking heatshield
for returning spacecraft or planetary lander.
aerosol Colloid of finely divided solid or liquid dispersed
in gaseous (esp. air) continuous phase. Natural
examples: smokes, dustclouds, mist, fog. In commercial
product active ingredient is expelled as aerosol by gaseous
propellant.
aerospace 1 Essentially limitless continuum extending
from Earth’s surface outwards through atmosphere to
farthest parts of observable universe, esp. embracing
attainable portions of solar system.
2 Pertaining to both aircraft and spacecraft, as in ‘aerospace
technologies’.
3 Activity of creating and/or operating hardware in
aerospace, as in ‘the US leads in aerospace’.
aerospace craft Vehicle designed to operate anywhere in
aerospace, and especially both within and above atmosphere.
aerospace data miner Analyses fleet performance (eg of
all aircraft of one type).
aerospace forces National combat armoury capable of
flying in atmosphere or rising into space, including all
satellite systems and strategic ballistic missiles.
aerospace medicine Study of physiological changes,
disorders and problems caused by aerospace navigation.
Among these are high accelerations, prolonged weightlessness,
vertigo, anoxia, ionising radiation, Coriolis
effects, micrometeorites, temperature control, recycling
of material through human body, and possibility of
developing closed ecological systems to support human
life away from Earth.
aerospace plane Colloquial term for space vehicle which
can re-enter, manoeuvre within atmosphere and land in
conventional way on Earth’s surface. Generally assumed
to be manned and to include some air-breathing propulsion.
aerospace relay mirror system Mirror [s] suspended under
airship at 65,000 ft (19.8 km) to relay beam from groundbased
laser to track and possibly kill objects in space
(AFRL).
aerospace warfare Conflict within and above atmosphere.
aerostat Lighter-than-air craft, buoyant in atmosphere
at a height at which it displaces its own mass of air. Major
sub-groups are balloons and airships. In airships aerodynamic
lift from hull can be significant, but not enough
to invalidate classification under this heading.
AETB
aerostatics The mechanics of gases at rest, in mechanical
equilibrium.
aerostation Operation of aerostat.
aerostructure 1 The wing [s], engine [s] and tail of a flying
boat (term now rare).
2 The supporting and controlling surfaces of an aeroplane
(also rare).
3 Today the term is usually synonymous with airframe.
aerothermal flow Slipstream past hypersonic vehicle in
upper atmosphere.
aerothermodynamic border Region, at height around
100 miles (160 km), at which Earth atmosphere is so
attenuated that even at re-entry velocity aerodynamic
heating is close to zero and can be neglected, as also can
drag.
aerothermodynamic duct Athodyd, early name for
ramjet. Aerothermodynamic in this context does not
necessarily conform to definition given below.
aerothermodynamics Study of aerodynamic phenomena
at velocities high enough for thermodynamic properties of
constituent gases to become important.
aerothermoelasticity Study of structures subject to aerodynamic
forces and elevated temperatures due to
aerodynamic heating.
aerotitis Pain in the ear caused by pressure difference.
aero-tow Tow provided for glider by powered aircraft.
Not normally applicable to banner or other towing.

bonded honeycomb sandwich materials.
Aerozine Trade name, family of liquid fuels based on
MMH or UDMH.
