Infrared Suppressor (DHC-6 IRS) significantly reduces
IR signature at all view angles around the aircraft. The
installation requires minimal modifications to the
airframe. Ease of interchangeability allows the IRS to be
used as a mission kit, with less than 4 hours required
for the B-kit installation.
Davis uses low backpressure ejectors and film
cooling to provide large IR signature reduction with
minimal aircraft performance penalty.
