STAR-M
which operate like human eye, with focal plane of input
optics covered with dense micro-mosaic of 2-D receptors
which ‘look’ continuously, direction of target being determined
from knowledge of which detector(s) see it.
STAR-M STAR (5)-mid range (over 30 kW).
starplates Upper and lower spiders each formed from
one piece of composite material or metal (titanium)
forging and forming structural basis of modern non-articulated
helicopter rotor hub. Not to be confused with star
(3).
Stars 1 Silent tactical-attack/reconnaissance system.
2 Plural of STAR, Star (1).
3 Standard terminal and arrival reporting system
(CAA).
4 Small transportable (or tethered) aerostat relocatable
system.
5 Surveillance and, or stand-off, target-attack radar
system (USAF).
6 Standard terminal automation-replacement system
(FAA, on-going).
7 Software technology for adaptable reliable system.
8 Space-based telemetry and range safety.
START Strategic Arms Reduction Treaty; *1, 31 July
1991; *2, 3 January 1993; *3, not yet ratified 2003;
*4, being discussed.
Start 1 Spacecraft technology and advanced re-entry
test.
2 Solid-state angular rate transducer.
3 Shf tri-band advanced range-extension terminal.
4 Special threat-awareness receiver/transmitter.
starter Device for cranking any prime mover of rotary
type during starting: 14 basic species.
starter exhaust Overboard discharge of exhaust from
starter of cartridge, monofuel, fuel/air, bipropellant or
air-bleed types; potentially dangerous.
starter gearbox Box containing gear train through
which starter cranks engine; may be reduction or step-up
gears.
starter/generator Single electrical machine, usually DC,
serving both as electrical starter and electrical generator
(see CSDS).
starter magneto Various forms of magneto designed to
provide powerful spark during start, eg hand-cranked,
impulse starter and LT boosting energy transfer.
Startex Start of exercise (UK).
starting chamber 1 Combustion chamber in multichamber
(multi-can) gas turbine in which igniter is fitted,
flame thereafter being carried round by inter-chamber
pipes.
2 Liquid-rocket precombustion chamber.
starting coil Auxiliary induction coil used as HT booster
when starting piston engine; alternatively used as energytransfer
LT booster.
starting envelope A plot of flight conditions within
which a [usually gas-turbine] engine can be started,
usually pressure altitude against dynamic pressure or
Mach number.
starting pressure Minimum rocket combustion pressure
at which nozzle exit plane is shock-free.
starting transients Temporary variations in pressures,
flows, velocities and temperatures during complete start
sequence of rocket.
starting vortex Transverse vortex left by lifting wing at
start of motion providing essential link behind subsequent
vortices from wingtips (part theoretical concept, since at
start wing may not be lifting and ** has zero strength, but
necessary because trailing tip vortices cannot have free
ends).
star tracker Optical or opto-electronic sensor which
automatically locks on to preselected celestial body or
bodies to provide input to astro or astro-inertial nav
system.
Starts Strategic arms reduction treaties.
startup Launch of new OEM.
start-up airline Commonly taken to mean first six
months’ operations.
start-up costs Those incurred in launching new type of
aircraft. Precise definition lacking; general opinion is that
it covers all costs up to certification, excluding related
engine and systems.
Star-21 Strategic aerospace review for 21st Century
(EU).
star washer Hard steel washer with multiple twisted
radial projections which bite into superimposed nut and
prevent it becoming loose.
STAS Space transportation architecture studies.
STAT 1 Statistical.
2 Statute (US).
state 1 Readiness condition of combat aircraft, from
cockpit-alert to unserviceable (different national subdivisions).
2 In connection with runway, condition of surface or
traffic occupancy.
3 For rotorcraft main rotor, usually three subdivisions:
propeller *, vortex ring * and windmill-brake *.
4 Amount of main propulsion fuel remaining, esp.
when running low.
State chicken Air-intercept code: fuel state requires
recovery, tanker or diversion (DoD).
State lamb Air-intercept code: “I do not have enough
fuel for intercept plus reserve required for carrier
recovery”.
state of occurrence State in which an incident, such as an
accident, takes place.
state of the art Level to which technology and science
have at any designated cut-off time been developed in any
given industry or group of industries (USAF).
State tiger Air-intercept code: “I have fuel for completion
of mission”.

(Eurocontrol).
static 1 At rest, or at rest relative to solid surface or local
atmosphere [ram pressure zero].
2 Structural test with application of single increasing
load.
3 Radio and other com. interference, esp. that due to
discharge of * electricity.
static air temperature Static temperature.
static balance 1 Aircraft condition in which there is no
resulting moment about any axis.
2 Control-surface condition in which in absence of any
applied torque surface is freely balanced about hinge axis,
either because c.g. lies on that axis or because mass
balance has been added.
3 Propeller condition in which when supported on rod
on knife-edge it rests in any position.
