METHOD TO START PYROTECHNICAL DEVICES AND DEVICE FOR ITS REALISATION Russian patent published in 2013 - IPC F02K9/95 

FIELD: blasting.

SUBSTANCE: when starting pyrotechnical devices of an object a signal is sent from a field-generating device arranged outside the object, through a field-generating device on the object, to igniters of pyrotechnical devices. Pyrotechnical devices are installed on the object in the form of a missile train, and the field-generating device is installed on the specified section of a rail guide. The first group of pyrotechnical devices designed for starting the last stage of the missile train, is arranged as capable of actuation at the first time interval after the missile train achieves the specified motion speed. The second group of pyrotechnical devices used to separate a test object is arranged as capable of actuation as a signal arrives from a field-generating device in the second time interval, shorter than the first one, after the missile train achieves the specified motion speed. The device for starting pyrotechnical devices comprises a field-generating device installed outside the object, and the field-generating device electrically connected at least with one of igniters of one of pyrotechnical devices and arranged inside the specified object, the following components placed in the object: an overload sensor, an integrator, a comparator, the first, second and third circuits of "AND" matching, the first and second duration shapers, the first and second output keys, a time-setting device, an "OR" matching circuit, a start pulse shaper.

EFFECT: inventions make it possible to increase reliability and safety of pyrotechnical devices actuation, and also to increase accuracy of starting stages of a missile train and ejection of a test object.
