1-10. HAZARDOUS COMPONENTS - Continued
The nozzle plate has two canned gas exit holes which provide axial thrust and impart a high spin rate to stabilize
flight. The primer, initiated by the firing pin, lights the igniter, which in turn ignites the propellant. The exhaust
gases are expelled through the nozzle holes and propel the flare out of the launcher, in a spin stabilized flight.
After approximately 1100 feet of travel (3.0 sec. ), the delay column burns through and ignites the payload.
Ignition of the payload causes separation from the rocket motor section. The display burns in upward flight,
through maximum altitude and in downward flight. The signal duration is approximately 10 seconds and provides a
10,000 candle power illumination, visible for 15 to 20 miles. The flare is approximately 2.0 inches long, 0.5 inches
in diameter, and weighs approximately 1/2 ounce. The flares are available in green, red, and white. The launcher
consists of a black anodized aluminum housing, spring, firing pin release knob, and a flare holder. All internal
parts are corrosion-resistant steel. The overall dimensions are 5. 5 inches long, 0. 8 inches in diameter and the
launcher weighs approximately 2-1/2 ounces.
