TM 1-1510-224-10 Section II.  AIRCRAFT SURVIVABILITY EQUIPMENT 4-2. M-130 FLARE AND CHAFF DISPENSING SYSTEM. a. Description. The M-130 flare and chaff dispensing system provides effective survival countermeasures against radar guided weapons systems   and   infrared   seeking   missile   threats.      The system    consists    of    two    dispenser    assemblies    with payload module assemblies, two control wheel mounted chaff     dispensing     switches     and     two     control     wheel mounted    flare    dispensing    switches,    and    associated wiring.        The    system    is    controlled    by    the    aircraft survivability equipment/avionics control system (ASE/ACS)   keyboard,   located   on   the   control   pedestal extension   (fig.   2-14).      The   flare   and   chaff   dispensing system    is    powered    by    a    5-ampere    circuit    breaker, placarded  M130   located   on   the   mission   control   panel (fig.  4-1). WARNING Right  engine  nacelle  dispenser  is  for chaff only. (1) Dispenser assemblies. Two interchangeable  dispenser  assemblies  are  mounted  on the aircraft.  One is located in the aft portion of the right nacelle and the other is mounted on the right side of the fuselage.    The  dispenser  in  the  nacelle  is  used  for  chaff only  while  the  dispenser  mounted  on  the  fuselage  can be  used  for  either  flares  or  chaff.    The  selector  switch (placarded  C-F)  on  the  dispenser  can  be  set  for  either chaff or flares.  The unit also contains the sensor for the flare   detector   and   the   sequencing   mechanism.      The dispenser    assembly    breech    plate    has    the    electrical contact pins .which fire the impulse cartridges. (2) Payload module assemblies. A removable   payload   module   assembly   is   provided   for each dispenser assembly.  Each payload module has 30 chambers which will accept either flares or chaff.  Flares or  chaffs  are  loaded  into  the  rear-end  (studded  end)  of the payload module, and secured in place by a retaining plate. (3) Flare    detector.        The    flare    detector    is provided   to   ensure   that   a   flare   is   burning   when   it   is ejected from the dispenser payload module.  If the initial flare    fails    to    ignite,    the    detector    automatically    fires another  flare  within  75  milliseconds.    If  the  second  flare fails  to  ignite,  the  detector  will  fire  a  third  flare.    If  the third  flare  ignition  is  not  detected,  the  detector  will  not fire  another  flare  until  the  system  is  activated  again  by pressing the FLARE DISPENSE switch. (4) Internal safety switch.    The  internal  safety switch (with safety pin and yellow flag), mounted on the right  rack  behind  the  copilot,  prevents  firing  of  chaff  or flares  when  the  safety  pin  is  inserted.    The  safety  pin shall  be  removed  only  while  the  aircraft  is  in  flight  or during test of the system. (5) Control    wheel    mounted    flare    dispenser switches.    Two  pushbutton  switches  placarded    FLARE DISPENSE,  one  located  on  the  top  right  portion  of  the pilot's control wheel and the other located on the top left portion  of  the  copilot's  control  wheel,  activate  the  flare dispensing   system   when   pressed.      Depressing   either one  of  the  switches  will  fire  a  flare  from  the  dispenser payload   module   each   time   it   is   pressed.      If   a   it   is pressed.  If a FLARE DISPENSE switch is held down, it will dispense a flare every 2.3 seconds until all flares are expended. (6) Control    wheel    mounted    chaff    dispense switches.    Two  pushbutton  switches  placarded    CHAFF DISPENSE,  one  located  on  the  top  left  portion  of  the pilot's  control  wheel  and  the  other  located  on  the  top right  portion  of  the  copilot's  control  wheel,  activate  the chaff dispensing system when pressed. (7) Wing    mounted    safety    switch.        A    wing mounted   safety   switch   (with   safety   pin   and   red   flag), located  on  top  of  the  right  wing,  just  aft  of  the  nacelle, prevents   the   firing   of   chaff   or   flares   when   the   pin   is inserted.      This   safety   pin   shall   be   inserted   while   the aircraft  is  on  the  ground  and  removed  prior  to  flight  or during system test. (8) Ammunition   for   dispenser.      Ammunition for  the  system  consists  of  countermeasure  chaff  MI  and countermeasure   flares   M206.      An   impulse   cartridge M796, fits into the base of either the flare or chaff and is electrically   initiated   to   eject   flares   or   chaff   from   the dispenser payload module. (a) Countermeasure  chaff    M1.      These units consist of a plastic case 8 inches in length and 0.97 inches square.  The base of the chaff case is flanged to provide   one-way   assembly   into   the   dispenser   payload module.        The    chaff    consists    of    aluminum    coated fiberglass strands. (b) Countermeasure flare  M206.  These units consist of an aluminum case 8 inches in length and 0.97  inches  square.    The  base  of  the  flare  is  flanged  to provide   one-way   assembly   into   the   payload   module. The  flare  material  consists  of  a  magnesium  and  teflon composition.      A   preformed   packing   is   required   in   the base   of   the   flare   unit   prior   to   inserting   the   impulse cartridge. (c) Impulse cartridge M796. This cartridge fits into the base of either the flare or chaff and is  electrically  initiated  to  eject  flares  or  chaff  from  the dispenser payload module. 4-4
