Construction: The flare consists of three main elements: (1) the flare case, (2) the illu-minating candle unit, (3) the 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 flare's free fall. The nose is threaded to receive 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 opened end contains in its center an ingnition charge 3 inches in diameter and 1/4 inch thick.

Length of illuminant container: 26 inches.

Length of illuminant: 24 1/2 inches.

Diameter of illuminant: 5 1/2 inches.

3. Model 1: A single silk parachute is housed in the after end of the body. It is surroun-ded by a layer of cardboard to insure smooth ejection.

Model 1 Modification 1: A small guide parachute and a larger parachute are housed in the after end of the body. They are surrounded by a layer of cardboard to insure smooth ejection.

Operation: Shortly after being released from the plane the aerial burst fuze operates. The resultant flash from the magazine ignites the ignition charge which in turn ignites the illuminant. The expanding gases force the end cap off and eject the parachute and illu-minating candle unit. The flare sheds a bright white light and burns for 3 minutes and 40 seconds.
