PYROTECHNICAL TORCH FOR FIREWORKS Russian patent published in 1995 - IPC

FIELD: fireworks articles. SUBSTANCE: after ignition of spark-forcing compound 2 and ejection of torch it turns to meet incoming stream of air. As spark-forcing compound burns out centers of mass and pressure are matching gradually which leads to loss of stability of torch. For prevention of this shell 1 is made from material which burning rate is faster than burning rate of spark-forcing compound 2. Thanks to this part of torch filled with spark-forcing compound acquires spherical shape which contributes to stabilization of trajectory of movement up to unpacking of pyroelements 3.
