PARTICLE SEPARATOR
NO. 230-706-501-XXX
The particle separator engine air induction system provides protection of the engine
against the ingestion of sand, dirt, and other foreign debris, with a minimum loss of
engine power. The particle separator kit, when installed, allows conduct of takeoff and
landing operations from unprepared areas. The particle separator kit is compatible
with the snow deflector kit, which is required for conduct of operations in falling or
blowing snow. The kit consists of the separator assemblies, bleed-air tubing and hoses,
purge switches, and other hardware required to complete the installation. The separators
are installed within the left and right air induction cowlings, and cause no aerodynamic
change to the helicopter. Each of the 530 filter elements (tube assemblies) in each of
the separators, through which all inlet air must pass, consists of a vortex generator
bonded into an inlet tube, and a second smaller tube which forms a scavenge chamber.
The vortex generators are 1.7 centimeters (5/8 inch) in diameter. When operating, foreign
particles which enter the filter elements are spun in the vortex generator and directed
centrifugally into the scavenge chamber. The debris within the scavenge chamber is
ejected overboard by the effect of bleed-air directed through venturis located at the
side and base of each separator assembly. The scavenge flow which carries the debris
with it accounts for about 8% of the total inlet air flow.
