Cutaway model of a 26,5mm Meldepatrone DM1 (26,5mm message cartridge German model 1). The message cartridge is meant to deliver a written message from an aircraft or helicopter to ground troops when the use of a radio is not possible or desirable for safety reasons. It is launched by means of a flare gun placed in a launch bracket in the cockpit. The plane launching the message projectile should not exeed 400 km/hr when launching.

Functioning of the cartridge:
The orange nosecone is pulled of the projectile, the written message is placed in the nosecone , and the nosecone is pushed back on the projectile. When the projectile is fired, the firing cap ignites the powder in the blue plastic cup. The hot gas starts pushing the projectile out of the shellcase, at the same moment the hot gas enters the central pipe and ignites the grains of smoke composition in top of the smoke generator. These grains consist of Potassium chlorate, lactose, black powder and the red dye methylamino- antrachinon and act as the ignition charge. Below that, four hard pressed rings of smoke composition are placed , consisting of Potassium chlorate, lactose and the red dye methylamino- antrachinon. The smoke charge burns for 30 seconds and clearly marks the place where the projectile has landed with red smoke. A two meter long white ribbon with red stripes is rolled up and placed behind the smoke charge. After firing it unrolls and marks the spot where the projectile has landed if the smoke charge has burned up before the projectile has been found
Length of the complete cartridge is 182mm.
Length of the projectile is 163,5mm.

Regards, DJH
