M-206 Flare, Aircraft: Countermeasure
The M-206 flare is the same length as the MJU-7 (8 inches), but half the cross-section (1 inch square). It uses a M-796 impulse cartridge that ignites the first fire mix simultaneously. The M-206 (T-l) is the simulator version of the flare. Approximately 120,000 M-206 and 4,000 M-206 (T-l) flares were used by ACC annually in the mid-1990s.
Flare, Aircraft: Countermeasure, M206 is an infrared decoy to be used with aircraft dispenser systems and shall not be substituted with the XM211 or XM212 flares.This flare is dispensed from aircraft to decoy infrared seeking missile threats away from the aircraft. The M206 flare is wrapped with an aluminum filament reinforced tape and inserted into an aluminum case that is closed with a felt spacer and a small plastic end cap. The top of the case has a pyrotechnic impulse cartridge that is activated electrically to produce hot gases that push a piston, flare material and end cap out of the aircraft into the air stream.
Self-protection flares are primarily mixtures of magnesium and Teflon (polytetrafluorethylene) molded into rectangular shapes. Longitudinal grooves provide space for materials that aid in ignition such as:
- First fire materials: potassium perchlorate, boron powder, magnesium powder, barium chromate, Viton A, or Fluorel binder.
- Immediate fire materials: magnesium powder, Teflon, Viton A, or Fluorel
- Dip coat: Magnesium powder, Teflon, Viton A or Fluorel
M-206 is a parasitic-type flare that uses an M-796 impulse cartridge. It is ignited in the aluminum case before it leaves the aircraft. Holes in the piston permit ignitor gases to contact the first fire mixture on top of the flare pellet. The parasitic type flare is less likely to produce duds. The plastic end cap falls to the ground following flare ejection. Flares are tested to ensure they meet performance requirements in terms of ejection, ignition, and effective radiant intensity. If the number of failures exceed the upper control quality assurance acceptance level (approximately 99 percent must be judged reliable), the flares are returned to the manufacturer.
The M206 flare cartridge is yellow-brown with an embossed F on the end cap. It is marked in black letters FLARE, AIRCRAFT, COUNTERMEASURE, M206 PCMK9311623, and the date loaded and the lot number. The AMD206 flare cartridge is similar in appearance to the M206. However, as currently fielded, it is a preproduction, developmental flare; the markings, handwritten using a black magic marker, are marked AMD206N with the flare lot number. A gray epoxy seals the end cap. The simulator is identical to the M206 flare cartridge except it has a blue end cap with an embossed S. It is marked in black letters SIMULATOR-IR FLARE SD-206 SOS P/N 117053-1, with the NSN and lot number. The M1 and M839 chaff cartridges are translucent gray with black designation markings.
