Wright-Patterson Air Force Base 4950th Test Wing 1975-1994 In   December   1975,   after   seven   years   of   operation   by Air   Force   Eastern   Test   Range,   the ARIA, re-designated   Advanced    Range    Instrumentation   Aircraft    following    completion    of    the   Apollo program,   was   transferred   to   the   4950th   Test   Wing   at   Wright-Patterson AFB,   Ohio,   as   part   of   an Air   Force   consolidation   of   large   test   and   evaluation   aircraft.   By   the   early   1980’s,   the ARIA   fleet consisted   of   eight   modified   aircraft,   six   EC-135N   aircraft   with   J-57   turbojet   engines   and   two   EC- 135B aircraft with TF-33 turbofan engines. Dedicated   to   support   of   worldwide   missile   and   space   testing,   the   aircraft   modifications   included a   7   foot   diameter   telemetry   antenna,   housed   in   a   ten   foot   radome   in   the   nose   of   the   aircraft.   It also   included   extensive   telemetry   communications   instrumentation   which   could   be   configured to   perform   telemetry   tracking   of   dynamic   objects,   telemetry   signal   reception   and   recording,   on board   data   processing   and   reformatting,   real-time   or   post-mission   (retransmission)   data   relay through   communication   satellites   via   high   frequency   radio   or   direct   line-of-sight   relay   to   ground stations,   and   voice   communications   relay.   In   addition   to   the   antenna   in   the   nose,   the ARIA   had a   probe   antenna   on   each   wing   tip   as   well   as   a   trailing   wire   antenna   on   the   bottom   of   the fuselage,    all    used    for    high    frequency    radio    transmission    and    reception.    Further    external modifications     included     antennas     for     post-mission     data     retransmission     and     satellite communications.    The    internal    modification    to    the    cargo    compartment    included    all    of    the instrumentation   subsystems   (Prime   Mission   Electronic   Equipment)   installed   in   the   form   of   a 30,000    pound    modular    package.    Modifications    also    included    provisions    for    eight    to    nine additional   crew   members   to   operate   the   instrumentation   equipment.   The   current   Prime   Mission Electronic    Equipment    was    organized    into    six    functional    subsystems    and    a    master    control console   to   provide   the   ARIA   mission   support   capability.   The   Antenna   Subsystem   acquired   and tracked,   either   manually,   automatically,   or   by   computer,   the   launch   vehicle   using   the   7   foot   dish antenna   mounted   in   the   nose   radome. The Telemetry   Subsystem   was   configured   as   a   set   of   six dual-channel   AN/AKF-4   receivers   that   received   the   vehicle   telemetry   signals.   The   Record Subsystem   was   designed   to   use   Inter-Range   Instrumentation   Group-standard   equipment   to meet   user   requirements   for   data   recording,   monitoring,   and   playback.   The   Timing   Subsystem, physically   collocated   with   the   Record   Subsystem,   served   as   the   central   timing   facility   for   the ARIA   electronic   suite,   generating   time   codes   to   permit   time   correlation   of   vehicle   events   during tape   processing.   The   Communications   Subsystem   provided   the   voice   communications   through three    1000    watt    single    sideband    high    frequency    transmitters    and    receivers,    and    data transmission   through   a   1000   watt   AN/ARC-l46   UHF   satellite   terminal.   The   Data   Separation Subsystem    further    processed    the    telemetry    signals,    generally    a    combination    of    several channels    of    analog    and/or    digital    information,    into    individual    measurements    for    on    board display.   The   last   module,   the   Master   Control   Console   was   operated   by   the   ARIA   mission coordinator, to control on board management merit of the instrumentation crew.
