Abstract

Launching and control of pyrotechnical systems at a specified coordinate is among the most complicated problems in the tests at a missile track. A method for launching and a corresponding device are proposed for activation of pyrothechnical systems of missile trains boosting along an ejection path to hypersonic velocities with ejection of an object to free flight. The method is based on generation of current pulses for activation of pyrotechnical systems of the moving stages of a missile train using inductive sensors. The principle can also be used for implementation of a noncontact method for activation of recording systems and a device for measurement of the mean velocity of an ejected object in continuous media. The method is based on the generation of starting signals (positive rectangular pulses) for activation of recording equipment with matching relative to the specified coordinate and measurement of the velocity of the ejected object at the moment when it passes through the measurement cross section. Methods for activation of recording systems and results of hydrodynamic and terradynamic experiments are presented.
