Construction of body: The flare consists of 3 main elements: (1) the flare case, (2) the illuminating candle unit, (3) in parachute.

1. The flare case consists of three sections: a nosepiece, body and end cap. The nose-piece is soldered securely to the body, and the hemispherical end cap is held in position by spot soldering in four places. Four tail fins are welded to the after two-fifths of the body. A steel ring 1 inch wide fits around the body at its junction with the tail cone. It is attached to the fins and serves to brace them as well as to retard the velocity of the flares free fall. The nose is threaded to re-ceive the fuze.

2. The Illuminant is contained in a cardboard canister which is covered by sheet brass 0.025 inch thick. The after end is closed by a steel plate held by screws to the cylinder. A 1/4-inch wire rope 65 inches long from which the candle unit is suspended is attached to this steel plate by means of a shackle. The forward end of the container is open and fits against a wooden block in the nosepiece. The illuminant at the open end contains in its center an ignition charge 3 inches in diameter and 1/4 inch thick.

3. There is a single silk parachute housed in the after end of the body. It is surrounded by a layer of cardboard to insure smooth ejection.

Operation: Shortly after being released from the plane the arial burst fuze operates. The resultant from the magazine ignites the ignition charge which in turn ignites the illumi-nant. The expanding gases force the end cap off and eject the parachute and illuminat-ing candle unit. The flare sheds a bright white light and burns for 3 minutes and 40 se-conds.
