The determination of detonation velocity is based upon measurement of the time interval needed for the detonation wave to travel a known distance through the explosive under test. The methods used to determine VOD may be classified as mechanical methods (Dautriche method), electrical methods [pin oscillographic technique (POT)], optical methods and radiographic methods. The methods which are generally used for the determination of VOD are ... [Pg.198]

Figure 3.19 A typical oscillogram for determination of detonation velocity.

There are some simpler methods which can be applied for the rough estimation of detonation velocity one such method is known as the Dautriche method . This simple method does not require the use of any special or costly instrument. The determination of detonation velocity is based on the fact that the processes that propagate at different linear velocities travel different distances in the same time. The difference in length of the distance traveled is a simple function of the velocities of these two processes. This method is mainly used for the determination of detonation velocity of commercial explosives. However, the same principle can be applied in order to determine detonation velocities of military explosives. The accuracy of the data obtained by this method is -4—5%. The Dautriche method for the determination of VOD of explosives as described by Meyer [80] is illustrated in Figure 3.20. [Pg.202]

Tlie principle of the continuous determination of detonation velocity is based on the continuous oscilloscopic recording of an electric resistance change of special types of probes through which constant current flows, caused the detonation wave propagation through the test explosive charge.
