Task of the present utility model realizes as follows: the body of flame bullet comprises interior copper seat, the papery cylinder, the shell case that choker block constitutes, propellant powder is housed in it from the bottom to top in turn, the cloth pad, paper washer, the felt pad, ignition charge, the ignition powder transitional medicine, catalyst, and paper washer, arm, the sign pad, center at choker block has manhole, an electric primer is equipped with in the bottom that is positioned at this through hole and propellant powder, this electric primer is by the positive pole of cylinder blanket as the contact utmost point, cylindrical core in the enclosure is as negative pole, insulation sleeve is installed between the both positive and negative polarity, negative plate links to each other with heating wire plate, and the heating wire that links to each other with heating wire plate links to each other with the ignition powder that is positioned at the electric primer bottom.

The emitter that is used to launch above-mentioned flame bullet comprises a fixed head, fixed block before, during and after being equipped with on it, before, during and after emitter is fixed on by standing screw together with the backing plate under it, insulation board on the fixed block, the front and back of emitter have several launching tubes, be contained in corresponding with each launching tube has several emission seats on the insulation board, front and back at emitter are equipped with radome fairing respectively, and distributor is housed on fixed head, and this distributor and aircraft mouth core plug join.

The utility model is owing to be that the signal flare housing is improved, former starlight body is become catalysis and transition powder column, and regulate the emission dose, ignition charge is a first order ignition charge, igniting easily, stable chemical performance, firing temperature is low, ignition powder is the second stage ignition medicine, and the ignition temperature of generation is also than the ignition charge height, and transitional medicine is an ignition charge of lighting the agent of catalysis flame, ignition temperature is than ignition powder height, these medicaments can control lag be lighted the agent of AgI flame after 4 seconds, be equivalent to fly light the catalysis medicament after 150 meters, produce required artificial-ice nucleus aerosol in the flight dropping process; Regulate the emission dose and can produce certain pressed gas, the place ahead powder column lighted and release shell case with certain speed, reach required range and unlikely destruction shell case and transmitter, make the powder column issuing velocity reach 55 meter per seconds, range owing to changing machinery percussion igniting into electric ignition, makes interior remote control of aircraft and automatic emitter flame bullet become possibility greater than 150 meters, simultaneously can strengthen bullet-loading capacity, and make Job Operations convenient.

Have several emission seats with the matching used transmitter of above-mentioned flame bullet, the distributor of its energising of control can make the electric primer of flame bullet pass to the work of rated current starting propellant powder, and emitter flame bullet speed is fast, the target standard.
