Adaps Automatic data acquisition and processing
system.
Adapt Air traffic [services] data acquisition, processing
and transfer (ATC Switzerland).
adapter Interstage device to mate and then separate
adjacent stages of multi-stage vehicle. Often called skirt,
especially when lower stage has larger diameter.
adaptive bus Digital data highway to which (almost) any
number of inputs and outputs may be connected.
adaptive control system Control system, esp. of vehicle
trajectory, capable of continuously monitoring response
and changing control-system parameters and relationships
to maintain desired result. Adapts to changing
environments and vehicle performance to ensure given
input demand will always produce same output.
adaptive-cycle engine Variable-geometry turbofan
providing high specific thrust for acceleration and
economical high BPR for subsonic cruise.
adaptive logic Digital computer logic which can adapt to
meet needs of different programs, environments or inputs.
adaptive nulling See Adars.
adaptive optical camouflage Active, self-variable form of
camouflage which, chameleon-like, alters emitted wavelengths
to suit varying background tones.
adaptive radar Usual [not only] meaning is antenna
automatically alters gain, sidelobes and directivity
according to received signal.
Adapts Adaptive diagnostics and personalised technical
support.
ADAR Air-deployed active receiver (ASW).
Adario Analog/digital adaptive recorder input/output.
Adars Adaptive antenna receiver system; antenna
(aerial) provides gain towards desired signals arriving
from within a protected angle while nulling those arriving
from outside that angle.
