The paper presents results of experimental work on ignition of layers of high explosive initiated by detonation wave. The high explosive layers were placed on the bottom wall of a detonation tube in which the detonation wave propagated. Measured ignition delay was in the order of some scores of microseconds and combustion of the layer had deflagrative character. Analysis of experimental results showed that ignition mechanism had mainly thermal nature and relation between ignition delay and temperature behind detonation wave could be described by Arrhenius' law. Also influence of combustion of high explosive on pressure behind detonation wave was investigated.
