Description: The cylindrical external case of sheet steel construction is closed at one end by a conical nose piece and at the after end by a wooden disk. The nose, threaded to receive a fuze, is filled by a wooden block. A black powder ignition charge is just aft of the block. The central body houses a parachute and a candle unit. The silk parachute is surrounded by a split cylindrical fiber housing. The shrouds are attached to a 1/8 inch wire rope 53 inches long which is attached to the candle unit. The illuminant is contained in a sheet-steel cylinder, open at the forward end and closed at the after end by a steel plate. The open forward end rests on the black powder charge in the nose. While carried in the plane a safety wire is passes through two eyelets at the tail end of the external case, preventing the parachute from coming out until the flare has been released from the plane.

Operation: When the fuze initiates explosion on the black powder charge, the resultant flash ignites the illuminant. The expanding gases cause both the parachute and the illu-minant container to be expelled out the rear of the flare case. The parachute housing falls away allowing the parachute to be opened.

The illuminant burns for 1 1/2 to 3 minutes with a greenish-white flame.

The main components of the illuminant are:
