In a device for optically tracing the trajectory of a powered flying body, especially a rocket, by mixing visible smoke and/or vapour particles with the emitted gas jet and/or passing air, a smoke and/or vapour unit is connected to the rocket nozzle and is activated or ignited by the rocket exhaust. Preferably, the smoke unit is in the form of a hollow cylinder (1, 2) containing a pyrotechnic mixture (9) of 22% zinc oxide, 18% polyvinyl chloride, a reaction mixture of 22% y chloride, 36% ammonium perchlorate and 2% collodion cotton. |
